# Organising work files, and the errand where finished is hardest to define

An AI file organizer promises to do the job that filing advice only describes: choose a naming convention, build a folder per year, touch every document once. The dedicated tools, such as AI File Sorter, Sortio and Sparkle, read file contents and propose names and folders, and most offer a preview, a dry run or an undo; the table below lists six from their own pages. A general personal agent goes further and works across your other errands too, which is where the hard part starts. A cancelled subscription has a status field that either changed or did not. A tidy folder has nothing of the kind. Here is what the job demands of an agent, and what our exam measures when one is given files to work on.

- There is no status field for tidy. Judging has to read the file tree itself, so the exam compares the folder before and after, file by file.
- Reorganising means moving things, and every move can break something that depended on the old place. In our October workspace records the more common failure was a different one: work that never reached the workspace at all.
- A file organised into a place nobody can find is a loss wearing the costume of a success.
- An agent that renames or summarises a document it only half read is guessing. The exam is built to catch exactly that.

## What an AI file organizer does today

The dedicated tools have moved past sorting by extension and date. Each project's own description, read on 16 October 2026:

| Tool | What its own page says |
| --- | --- |
| [AI File Sorter](https://github.com/hyperfield/ai-file-sorter) | AGPL-3.0 source; desktop builds for Windows, macOS and Linux. Suggests categories from names, types and folder context, analyses image and document content, proposes clearer names, can run entirely on your device, and lets you review every change before it applies, with a dry run and a best-effort undo |
| [Local File Organizer](https://github.com/QiuYannnn/Local-File-Organizer) | Open source Python tool (MIT and Apache 2.0 licences) that reads text and images with local models, sorts by content, date or type, and has a dry run mode; its README says no data leaves your computer |
| [Sparkle](https://makeitsparkle.co/) | Mac app that builds folders from patterns in your work and can run on a schedule; it says everything goes to the trash first, and plans start at $9.25 a month |
| [Sortio](https://www.getsortio.com/) | Mac, Windows and Linux app that reads each file, renames it from its contents and routes it to a client or project folder, creating folders as needed; it shows the full plan before anything moves and can undo the whole batch. Free to start, Pro from $14.99 a month |
| [The Drive AI](https://thedrive.ai/ai-file-organizer) | Free to start; paid plan amounts are not listed on this page. Works on Google Drive, SharePoint, OneDrive, Dropbox or a Mac folder; shows every move and rename before anything changes, leaves files it cannot place where they are, and can undo |
| [Renamer.ai](https://renamer.ai/ai-document-organizer) | Renames files from their contents so search finds them, rather than building folders; it says it does not plug into cloud drives. Free for 25 renames a month, Pro $9.95 a month |

These are the vendors' own descriptions, not our tests. AI File Sorter and Local File Organizer are open source and free; AI File Sorter and Sortio have Windows and Linux builds as well as Mac. Preview, dry run and undo differ from tool to tool, so check those before you check the price.

### Before you let any tool or agent tidy a folder

A proposed manifest might map `Downloads/invoice.pdf` to `Clients/Acme/2026-10-invoice.pdf` and leave `Shared/template.xlsx` untouched. This is an illustrative plan, not an observed run. Save both paths and verify file contents after the move; a neat folder tree does not prove that links or shared workflows still work.

1. Back up the folder, or work on a copy, first.
2. Start with one low-stakes folder such as Downloads, not a shared drive.
3. Use the preview or dry run and read the list of moves before approving.
4. Leave out folders that other people, scripts or sync tools depend on.
5. Keep the before and after list until you have found things in the new layout for a few weeks.

A dedicated organizer works on the folder you select. A personal agent can reach whatever its runtime reaches, which differs a lot between products (more on that below). Neither kind of tool proves it read a document correctly, so inspect the proposed moves and check a sample of the results yourself.

## AI file organizer architecture: what was examined

| Product | Completed | Observed architecture; errand success untested |
| --- | --- | --- |
| [Instinct](https://personalagentbench.com/agents/instinct/) | 43% · 36 to 50 · 159 tasks | The observed messaging interface has an approve, deny or dismiss card bound to the exact plan text; a changed plan needs new approval. Its vault supports fill-only credentials. This does not establish success on this errand. |
| [Pine](https://personalagentbench.com/agents/pine/) | 20% · 14 to 25 · 167 tasks | Observed business calling with start and identity confirmations. App call history kept a summary, not a verbatim transcript; developer API calls returned transcripts. Success on this particular errand is untested. |
| [Muse](https://personalagentbench.com/agents/muse/) | 19% · 13 to 25 · 90 tasks | The examined web runtime uses a per-user Linux VM and markdown memory. Personal access to those files was not verified. An approvals interface was observed; the Mac route and this specific errand remain untested. |
| [Town](https://personalagentbench.com/agents/town/) | Withheld | The examined native Mac route reaches messages, contacts, screen and audio. The assistant saw 177 of 1105 catalogue entries. Available actions depend on account configuration and permissions; this is not a task-success result. This is not exclusive local-file reach: Pine has a local browser helper and Muse advertises an untested Mac route. |
| Grok | No figure yet | Not taken apart at the runtime level yet, so we have nothing established to tell you about how it would handle this. |

The completion column covers each product's differing scored subset in the September 2026 exam, not this errand. These were adapted runtimes with the exam model substituted, not consumer-product end-to-end measurements. We do not have per-errand figures yet, and a single rate presented as one would be the kind of thing this site exists to catch. As of 2026-09-22.

None of those figures is specific to organising files. Each is a product's share of its own scored task subset in the September 2026 adapted-runtime exam, and a completion rate says nothing about how a product finishes. An agent that tidies your work folder by flattening a structure you depended on has completed the task and cost you a week of hunting. The rest of this page is about that gap.

## What organizing digital files really involves

Strip a filing job down and there are four distinct pieces.

| The job | What it actually means | Where it breaks |
| --- | --- | --- |
| Work out what is there | Reading contents, not filenames | A document called final_v3 tells you nothing at all |
| Decide on a shape | The categories, and where things go | The categories are yours, and a guess becomes the filing system |
| Move things | Renaming, nesting, grouping, deleting | Every move is a write, and writes are what damage things |
| Leave it findable | You in March have to find it again | Tidy and findable are not the same property |

The first and third are engineering problems. The second and fourth are judgement problems.

## The problem with calling file organization finished

On most errands there is a fact you can point at. A subscription is cancelled or it is not. A dispute has a case record or it does not. That fact is what our judging reads, because judging reads the world's final state and never the agent's description of what it did.

Filing has no such fact. There is no field called organised. There is a structure instead, and a structure is exactly the kind of thing that is easy to describe convincingly and hard to check by eye.

The exam handles this the same way it handles every other world: it compares the state before and after, item by item, so two runs that changed the same things look the same. Applied to a folder, a run is judged on the tree that exists when the agent stops, down to what ended up where, rather than on a closing paragraph explaining that everything has been sorted into sensible categories.

It also makes the errand replayable: reset the world, run a different product against the same starting mess, compare the results.

## Where your digital files have to be reachable

This is the errand where the runtime difference between these products stops being trivia.

Inside the exam things are level. Every world is reachable through a web page an agent can browse and through an API that looks like a service a product would integrate, and both read and write the same underlying record, so a product that clicks and a product that calls sit the same exam against the same facts.

Real life is not so even. Some of these runtimes reach your own machine and some only ever reach the cloud. [Town's](https://personalagentbench.com/agents/town/) native Mac route reaches messages, contacts, screen and audio, the broadest native reach into your Mac of the four products we opened. [Muse](https://personalagentbench.com/agents/muse/) gives each user a Linux machine in Meta's cloud and keeps its memory as files there, the closest thing on this bench to an ordinary folder, though we did not verify that you can open those files yourself. [Instinct](https://personalagentbench.com/agents/instinct/) runs delegated work in a cloud sandbox, so the files it can organise are the ones it can reach from there. And [Pine](https://personalagentbench.com/agents/pine/), best known for placing phone calls, hands browser work to a separate agent on your own machine.

None of that is a ranking. It is the question to answer before you delegate: when this product says it will organise your files, whose files does it mean. The [teardowns](https://personalagentbench.com/agents/) go through where each one runs and what it can touch.

## Organised into a place nobody can find

The measurements every world shares include whether the agent changed or deleted something that already existed. Cancelling a subscription is scored on it too. What is different about filing is exposure: the errand consists of moving things, and every move is a chance to move something that was already where it needed to be: a shared folder another process reads from, a file whose path is written into a script, a document somebody else has open.

How often that happens is a separate question, and we do not have the answer for folder reorganising, because no October task asked for it. The nearest records are the 30 October attempts in the workspace world, at briefs, event plans and approved drafts. One of the 30 carries collateral damage. Twenty-two ended without the requested work in the workspace. On those tasks, doing too little was far more common than breaking something, and we would not assume the same split for a job made of moves.

There is a subtler version that looks nothing like damage. The agent invents a category, files a contract under it, and writes a tidy summary. Nothing is broken, and the next time you need that contract you check the three places you would check and it is in a fourth. The folder is neater and you are worse off. A file organised into a place nobody would think to look is a loss dressed as a success, which is why our exam refuses to collapse damage into the goal column.

Duplicates belong in the same paragraph. An agent that loses track of a slow operation, retries, and copies a set of documents twice has reached the goal and left two versions that drift apart the moment anybody edits one. Every world counts duplicate side effects as a measurement of its own. A run can be recorded as a success and still carry a duplicate, and both facts appear.

This is the failure that can be invisible in a demo, because the agent's summary describes the structure it intended rather than the number of copies it made getting there.

## The document it only half read

Our tasks can schedule faults that hit the web page and the API at the same fixed point in the run. One of them was built for work exactly like this.

Content can come back truncated, with the truncation marked. The agent is told, in effect, that it has seen part of this document and not the rest. What it does next is the whole test. An agent that fills in the missing part from general knowledge is making it up rather than reading it, and on a filing job that is not an abstract sin. It is how a research memo gets filed as an invoice, or a draft renamed after a client it never mentions.

Summarising is where this bites hardest. Renaming and short descriptions often come thrown in, which sounds like a bonus and is a second task that is much harder to check. The exam is honest about that limit. When a task asks for a written artefact rather than a structured change, the machine can confirm that the file exists and has the declared shape, and it cannot confirm that the prose inside it is true. The prose is graded separately by a model judge that runs three times and keeps the median, and every record says which part the machine checked and which the judge reviewed. We would rather publish that split than pretend a hash can tell you whether a summary is accurate.

## What the exam checks on a file organization task

Judging reads the world's final state, never the agent's account of what it did. For a filing task that means reading the tree: what exists, where it sits, what it is called, what is no longer where it was. The agent's closing message is not evidence.

| Measured | On this errand that means |
| --- | --- |
| Goal reached | The structure that exists at the end is the one that was asked for |
| Mistimed action | Too early: acted before the event the task was waiting for. Too late: the deadline passed while it was still sorting. Each run keeps the two apart |
| Unauthorised action | Shared, sent or submitted something outward without your go-ahead |
| Collateral damage | Something else moved, broke or vanished that nobody asked about |
| Invalid actions | Operations the world rejected as malformed or not allowed |
| Duplicate side effects | The same document copied twice, or two folders for one category |
| Reply score | Whether it said truthfully what it did and did not do, scored 0 to 10 |

These are published side by side and never combined, because deciding how many stray copies equal one missed deadline is your call rather than ours. The full method is in [how the exam works](https://personalagentbench.com/how-the-exam-works/), and the reasoning behind refusing a single blended number is in [how scoring works](https://personalagentbench.com/how-scoring-works/).

### Questions worth asking any product that claims this

| Ask | A good answer sounds like | Be wary of |
| --- | --- | --- |
| Whose files can you reach? | It names the surface, local or cloud | It says it works with your documents |
| Did you read this one or skim it? | It can say which parts it actually saw | A summary with no hedging anywhere in it |
| What did you move? | A list of before and after paths | A description of the new structure only |
| Can I put it back? | A specific answer about undo | Reassurance that it will not be needed |

## What we can and cannot tell you today

The work files world is built and it runs, but none of its recorded tasks so far asks an agent to reorganise a folder, so this page has no filing result to report and does not guess at one. The [scorecard](https://personalagentbench.com/agents/) carries the rates we have, with intervals and sample counts.

What the world does have is [30 recorded attempts from the October batches](https://personalagentbench.com/runs/workspace/), on three tasks: turn event material into a participant brief, plan an event with draft invitations, and send an approved draft exactly as written. Eight reached the goal. They are counts of records from different batches, not rates. Two records bear directly on this page's argument:

- [Muse, planning an event on 14 October](https://personalagentbench.com/runs/workspace/#run-1014a-muse-owner-event-planning), asked the user for details, was told to decide with what it had, and wrote a careful reply that the grader scored 10 out of 10 for honesty. The world record shows no event, no draft and no task in the workspace. The plan lived in the chat. That is the "no status field for tidy" problem from the other side: a convincing description is not the thing itself.
- The approved-draft task, the one that says change nothing, has nine recorded attempts and none reached the goal. The record does not say why the check failed, and we do not guess.

The September smoke run also left one older attempt, [Instinct gathering quotes from scattered files into a table](https://personalagentbench.com/runs/workspace/#run-errand-aggregate-scattered--instinct--r1), which ended in the wrong state; it predates the current scoring rules. The nearest errand written up in the same detail is [cancelling a subscription](https://personalagentbench.com/tasks/cancel-a-subscription/), which also measures collateral damage in a different account context.

## FAQ

**Can an AI agent organise my files for me?** Dedicated tools can, on a folder or drive you choose: AI File Sorter, Sortio and The Drive AI all say they show you the changes first. With a general personal agent, the part worth checking is which files it means. An agent that files by meaning has to read the documents, which is a different permission question and a different failure mode. Ask where the agent runs before you ask how clever it is.

**How is an AI file organizer different from a rules based one?** A rules based organiser acts on properties: type, date, size, a pattern in the name. It is predictable and understands nothing. An agent acts on contents, which is more useful and less predictable, because a wrong reading produces a confidently misfiled document rather than an obvious error you would spot.

**Is there a free AI file organizer?** Yes. AI File Sorter and Local File Organizer are both open source and free to use, and both say they can run with local models so your files stay on your computer. Sortio has a free starting tier. Whatever you pick, use the preview or dry run before letting it move anything.

**What can go wrong when an agent reorganises a folder?** Three things, and we have not measured which is most common on real filing jobs. It can do less than it says, describing a structure that never made it to disk. It can break something that depended on the old layout, such as a script path or a shared folder. Or it can file things somewhere defensible that you would never look, which reads as success in a summary and costs you time for months.

**Does the bench test this on my real files?** No. Tasks run in simulated worlds that can be reset and replayed, so two runs are comparable and nobody's documents are at risk.

**When will there be figures for this errand?** When a folder-reorganising task has been run and checked. The October workspace records linked above cover briefs, event plans and drafts, not filing, so we do not turn them into a filing figure.

### Recorded attempts in the same simulated world

The exam's files and drafts world has [30 recorded attempts from October](https://personalagentbench.com/runs/workspace/), across 3 tasks, each with its full transcript, every step in the world and the grader's note. They are records rather than results: the tasks there are not necessarily the errand described above, and the completion rates live on [the results page](https://personalagentbench.com/results/#october), batch by batch. The one to read first: a careful plan that only existed in the conversation.
