Questions people ask.

Bohm is an AI browser where you make apps by describing them, and keep using them. Write the app you want and the AI makes it in Bohm; its data stays on your PC, and you can change it by pointing at what should be different. An HTML app you already have runs here too. Beside your tabs, a chat reads the web pages you have open, fills in and clicks when you ask, and can keep its answer as an app.

Bohm is free.

The engine is. The runtime that runs your apps, keeps their data and applies changes — bohm-runtime — is open source under AGPL-3.0, so anyone can read what it does with an app and its data. The browser app around it is free to use under its license agreement. Source code on GitHub

Windows 10 and Windows 11. It installs into your own user folder, so it does not need administrator rights, and the installer works without an internet connection.

Apps that live in one HTML file — a tool, a tracker, a small dashboard. Bohm makes them when you describe one, runs them without changing their code, and gives each its own tab and its own place for data.

Describe it in Bohm: on the first screen, or with “Make an app” in a new tab. The AI you connected makes it the way Bohm keeps safe, and you try it before you save it. Making it in another AI chat instead? Paste our short text in with your request. Making an app for Bohm

Yes — that is the main way. Describe the app in Bohm and it is made there. You can also open the web pages that have the information, ask Bohm’s chat about them, and choose “Save as app” under the answer; that app reads the same tables again whenever you choose “Read again”. How it works

Choose “Change…”, click the part of the app you mean, and say what should be different. The change arrives as a suggestion you can try in place before you apply it. You can also drop in an updated file as a new version. Either way the data stays.

No. Bohm blocks an app’s connections to outside servers and shows you what was blocked. Links to the web ask before they open in a new tab.

In one folder on your PC — the apps, what you entered in them, every version, your settings and your history. iyulab does not run a server that receives them.

Nothing is lost. App data is kept by Bohm in its folder, not in the browser’s cache, so it is there after a restart.

Yes. Every version is kept, and “Previous version” brings back both the code and the data as they were. What you wrote in the newer version is kept aside, and even after you go on writing in the older one you can merge it back in — unless both changed the same record differently.

Copy Bohm’s folder to back everything up, or export one app with its data and versions and import it on another PC.

Yes. In the app’s info, “Records as tables” saves what the app keeps as tables (CSV) in your Downloads folder — one file per kind of record — that Excel or another spreadsheet opens. It works even when the app has no export button of its own, and the app stays as it is.

No. Apps without AI need nothing. For AI you can connect a service with your own key, pick a model file on your PC, or use an AI server on your network.

In the Windows credential store. When an app calls an AI service, Bohm answers with your key; the app never sees it.

Yes — with a model file on your PC, or an AI server on your own network. Results depend on the model; a stronger one is more reliable.

Only the pages you ask about, and only the AI you chose for the chat. Pages at addresses inside your network, and sites you or your IT team list, are never handed to an online AI service.

Only when you ask it to in the chat. By default it asks you before submitting a form that sends or changes something, or pressing anything that pays, posts, sends or deletes — a search goes ahead. You can set it to read only.

Yes. You sign in in a web tab as usual, and the app reads the table from that open tab — as you. Your password is never given to the app, to the AI or to us.

An app builder runs on a server, so reading a page behind your sign-in needs your password, an API key or an integration. An app in Bohm reads the tab you already have open, works on sites that have no API, and keeps what it reads on your PC. Gallery

No. The AI is used once, to make the app. Reading again follows fixed rules for the same site and columns, and tells you if the page no longer matches.

Crash and error reports and a daily “started” note while Bohm is being stabilized — with no app names, inputs or file contents. A weekly usage record only if you turn it on. Anything else only when you use “Tell us” and press Send. Privacy policy

Yes. Apps keep running, nothing signs in or checks with a server, and AI can come from a model on the PC or an AI server on the same network.

Yes. Through Windows policy, IT can set which AI servers and models people choose from, list sites that are never sent to an online AI service, and turn off diagnostics, the usage record, “Tell us” and the update check. For IT teams

Yes. When it starts and once a day it checks for a new public release and, if there is one, gets it in the background and checks that it is signed by iyulab. Restart when it says the update is ready — or it updates when you close Bohm. Your apps and data stay where they are. IT can turn this off.
