A Windows app that runs your files, types what you say, and remembers what you do. It replaces the folder window you open a hundred times a day — and unlike that window, it was paying attention.

Separately they're useful. Together they're something else.
Browse your actual disk. Rename, move, copy, compress, delete — with progress bars, undo, tabs and a preview pane. Fast in folders that make Explorer crawl.
Connect Gmail, Slack and your calendar with one paste each — an app password, a token, a secret calendar link. No Google sign-in, no developer setup. Then ask "who am I ghosting?" or "what's on today?". Read-only, stored on your machine.
It reads your screen as text, on your own machine, so it already knows what you're doing instead of having to be told. No picture is ever kept — and it can take one look at the actual screen when you ask about something you can only point at.
Press one key anywhere in Windows, speak, and your words are typed into whatever app you were in. Punctuated, tidied, filler removed. It works on a plane.
It reads inside your PDFs, Word files, spreadsheets and slides — so you can search for a sentence you remember rather than a filename you don't.
“Where's the contract I was reading yesterday?” “What did I work on last week?” “Move all the PDFs in here into a folder called Invoices.” It shows you exactly what it intends to do before it touches anything.
Point it at Documents, or a whole drive, and it quietly reads the text out of every PDF, Word file, PowerPoint, spreadsheet and ebook it finds. Then “the contract with the ninety day notice period” is a search that works. All of it happens on your processor.
Deletions go to the Recycle Bin. Collisions ask before replacing. Every change it makes is undoable with Ctrl+Z, including the ones it made on your instruction.
Assistants that remember your work either keep video of your monitor, or ship your screen off to a server to be understood. BOND does neither. It reads the words in the window you're actually in, on your own processor, and keeps only the words — so it knows what you're working on without there ever being a recording of you.
Speech recognition runs inside the app, on your processor. No audio is uploaded, ever, by anyone — including us.
It reads the active window only — never what's behind it — through the accessibility layer Windows already ships, so nothing is uploaded to make sense of it. Only text is kept, only for a fortnight, and a badge sits in the title bar the entire time it's running. One press pauses it, one button deletes everything it has. Password managers, banking and health windows are refused outright, and card numbers and API keys are stripped before anything is written down.
Nothing is uploaded, synced or copied to a cloud. The memory of your work is a database on your own disk that you can delete at any time.
Browsing, file operations, search and dictation all work offline. Only the conversational part needs a connection — and it tells you plainly when it can't reach it.
Prefer not to use ours? Point it at OpenAI, OpenRouter, Groq, or a model running on your own machine. One field in Settings.
The app is free. What you pay for is a better brain behind it.

Prices shown are provisional while BOND OS is in early release.
One installer. About 135 MB, because the speech model lives inside it rather than on someone else's server.
It keeps itself current. New versions are offered inside the app and install when you say so — you will not have to come back here.
Windows may warn you about an unrecognised app the first time. Choose More info → Run anyway. We're in the process of getting the installer signed, which removes it.
