What Filer Does — Every Feature in One Place

Explorer — your files, the way you already work

Filer is a file explorer first. Everything below starts from the folder you have open.

Browse, open and organize: Folders, files, a folder tree and a Details view whose columns you can resize by dragging a column’s edge — a double-click on the edge restores its width. In a narrow window the tree and the chat give up space before the file list does.
Delete the way your computer does: Delete moves the selection to the Trash or the Recycle Bin at once, as Finder and File Explorer do, and a short message names what moved. Deleting permanently still asks first.
Recent folders are the folders you worked in: The address bar remembers the last ten folders where you created, renamed, moved, copied, deleted, compressed or extracted something, or opened a file — not every folder you passed through.
Compress and extract: Make a zip of a selection beside it, or extract one where it is.
At home on a Mac: A full menu bar (File, Edit, View, Go, Window, Help) with the shortcuts Finder uses, the keys of Finder’s file list, a navigation pane that starts where Finder’s sidebar does, and files shown with the icon Finder shows for them — a file you drag out of Filer carries it. Folders keep Filer’s yellow folder.

The chat sits beside the file list and works on the folder you are in.

Ask, summarize, explain, translate: Ask about a file or a whole folder in your own words, or right-click a file for a ready-made action. Filer reads the files itself — there is nothing to upload.
Reads like a messenger: Your messages on the right, Filer’s on the left.
Asks before it changes anything that matters: Depending on the folder’s trust level, when the chat wants to overwrite, move or delete a file it shows you what it is about to do and waits for your answer.
Scanned documents: With the Image Understanding add-on installed (Settings › AI › Add-ons), a PDF page that is only a picture is read, and so are the pictures inside a document. Without it, asking about a scanned document points you to the add-on.

Find looks for files by their name, and answers at once.

Patterns and filters: Type part of a name, or a pattern such as *.png or report*. Narrow it by file type, size, date modified, or matching upper and lower case.
Where to look: The current folder, your knowledge base, or any folder you paste in.
Always current: Filer keeps a list of the files on your computer so a name search does not wait on the disk. If a folder or a drive could not be read — one that was disconnected, for instance — the status bar says Search index partial and names it on hover.

AI Search finds files by meaning, not by name, in the files you asked Filer to remember.

The folder you are in is the scope: Search from a folder and the results come from that folder and everything under it; step into a subfolder and the same search narrows with you.
Widen in one press: When nothing in the folder matched, or a better match is outside it, one button runs the same search one folder up — or in the folder that holds the better match.
Answers, not just files: Ask a question in the chat and Filer answers from the passages it found, naming the file each answer came from. See it step by step.

The Vault is the list of files and folders Filer has read and remembers — the knowledge base AI Search and the chat answer from.

Remember a file or a whole folder: Ask in the chat (“remember everything in this folder”) or add a folder in the Vault. The Vault shows what was read, what is still being read and what could not be, with a filter by status.
Followed folders keep up: A folder added in the Vault is followed: files you put in it later, or change, are read too, and files you delete or move out are forgotten. Stop following ends it — what was read stays.
Stays on your computer: With the built-in models, reading and remembering happen on your computer; your documents are not uploaded anywhere to be searched.

Turn on Filer AI for a folder and tell it, in plain words, what to do with what arrives.

Instructions in plain words: “When a new receipt arrives, add it to the expense sheet.” Filer shows what it understood as rules you can read before anything runs. Set up with AI looks at the folder, asks a few questions and proposes the instructions and settings next to what is set now — nothing changes until you press Apply.
When it runs: When files arrive or change, on a schedule, when a message comes in through a connected app, or when another folder hands it a file.
Activity: Every run, what it did, and the approvals waiting for you, in one place. Filer can also tell you with a desktop notification when a task finishes or needs your approval while its window is behind another (Settings › Notifications).
Trust levels you choose: Each folder has a trust level, from read-only to fully automatic, that decides what it may do without asking. A folder that arrives with its own raised level — copied from another computer, say — runs at Productive until you choose to use it, and Settings says which level, rules and plugins came with it.

Plugins add actions and connect Filer to other apps.

Messaging and services: Telegram, Slack, Discord, email, Notion and webhooks — so a folder can send what it made, or take instructions from a message.
Documents and media: Converting documents (including to PDF, where Microsoft Edge is available), transcripts, redaction, video and more. Each one adds its actions to Filer’s own right-click menu as soon as it is installed.
Only what runs here: A plugin that needs a program or a browser this computer does not have is not offered here.

Filer works with the model you choose.

A local model, no account: Filer can download a model that runs on your computer. Before you pick one, each says how it would run here — a model that would run from system memory says it may be slow, and one that cannot run says so. A download can be stopped and picks up where it left off next time.
Cloud models with your own key: Use a cloud model with your own API key; you pay the provider only for what you use.
Your company’s endpoint: Point Filer at any OpenAI-compatible endpoint your company runs. Filer for teams.

Filer updates itself.

Updates: Filer checks for a new version when it starts and offers it when one is ready; on a Mac it also checks every few hours while it stays open.
