Bohm

Free · Open-source engine · Works on internal networks

The web browser that works with AI.

Ask about the tabs you have open, let it fill in and click — with you deciding — and have the pages you check read again on their own. It is also where the apps you describe live: made here, kept on your PC, still working next month.

AI web browser

AI that works in the tabs you have open.

The chat beside your tabs reads the pages you have open — in your own tab, signed in as you — answers, fills in and clicks. The steps that matter wait for you.

Bohm’s chat beside a web page, answering from the three open tabs
Ask about open pages. Compare, summarize or pull tables together across the tabs you have open. The pages it read are listed under the answer.
Let it fill in and click. Ask it to open a site or do something on a page. A search goes ahead; anything that submits, pays, posts, sends or deletes waits for your confirmation.
An app saved from an answer, showing league tables read from three web pages, with Read again
It reads them again on its own. Save an answer built from a web table as an app. “Read again” reads the same pages with the same rules — no AI needed — and can do it on its own every few minutes while Bohm is open.

Why an app in your browser, not an app builder

And still the browser you use every day.

Tabs that behave. Vertical tabs for apps and the web, pinned pages (Ctrl+D), a closed tab back (Ctrl+Shift+T), Ctrl+1–9, and last session’s tabs restored.

Your search, your history. Type an address, a search or a question. Point the search box at the search you use; history stays on this PC.

Skills and MCP. Add your own skills — guides the AI follows — and connect MCP servers. The AI asks before it uses a tool.

Zoom, downloads, sign-in. Zoom each tab, follow a download and find it in its folder, and stay signed in to the sites you use — passkeys included.

Why Bohm

Making a useful app with AI is the easy part now. Keeping it in use is where it stops. Clear the browser and the records you kept are gone. The AI key gets pasted into the file. A new version no longer fits the data you already entered. Bohm is a browser built for that second part: the place you make an app is the place it keeps running. An app you make stays on your PC as a file, and keeps opening even if the AI service you made it with changes or ends.

How it works

Describe it. Use it. Point at what should change.

Describe it. Write the app you want on the first screen. The AI makes it and shows it to you — try it, and keep it if you like it. It gets its own tab and its own place for data.
A receipt expense app made in Bohm, listing expenses with their receipt photos
Use it every day. What you enter is saved to a folder on your PC. Close the tab or restart the computer — it is there the next time.
The expense list pointed at, and beside it the request for a trip field and the suggested change
Point and ask for a change. Click the part you want different and say what should change. It arrives as a suggestion; apply it and your data stays.

Your data

The app can be made again. The data cannot.

Make the app again and change it as often as you like. Its data, and what it may send out, stay in Bohm’s keeping.

One folder on your PC. Apps, their data and your settings live in one folder. Copy it to back up, or export one app with its data and versions.
One step back, always. Every change you apply becomes a new version, and its data carries over. «Previous version» brings back the code and the data as they were.
Nothing disappears quietly. Archiving keeps the app and its data. Deleting moves them to the Recycle Bin, where you can still restore them.

AI inside your apps

Apps that call AI, without a key in the file.

Your key, kept by your computer. When an app calls an AI service, Bohm answers with the key you connected. The key stays in the Windows credential store, or the Keychain on a Mac, and is never handed to the app.
Or a model on your PC. Without a key, apps can get their answers from a model on your PC — pick a file you have, or let Bohm get one for you (it tells you the size first). Quality follows the model — a stronger one gives more reliable results.

Internal networks

Works well on an internal network with no internet.

Bohm runs on your PC, so it works the same on an internal network — a company network, say — that cannot reach the internet.

Works on an internal network. The apps you made or brought in keep running where the internet cannot be reached. Nothing signs in or checks with a server first.

Apps cannot reach out on their own. An app that tries to reach another site is blocked, and Bohm tells you what it tried. An app’s AI requests go only to the AI you connected.

See what went out. Settings shows what apps sent off this PC in this session, and every connection that was blocked.

Gallery

Made by asking. Watch how, then try it.

The engine is open source.

The runtime that runs your apps, keeps their data and applies every change is published under AGPL-3.0. What Bohm does with an app and its data is there to read, not to take on trust. (The part that writes and changes apps with a model is in the app, not in the published source.)

An AI file explorer, and working agents for your folders.

Visit Filer

  • An AI file explorer

    Ask about the files in the folder you are in, or right-click any file for a one-off.

  • Working agents for your folders

    Write what you want in plain language. The folder’s agent works when files arrive, on a schedule or when a message comes in — and keeps going while you are away.

Bohm and Filer share one idea. Make it in plain words, use it, change it whenever you like — no developer in between.

Try Bohm.

Bohm is free for Windows and Mac, and works well even on an internal network with no internet access.
