a local AI agent

Say what you want. Your computer does the rest.

knaif is a small AI that runs on your own machine and does the fiddly jobs — shrinking a video for a chat app, combining a stack of scans into one PDF, converting a document into the format someone asked for — from one plain sentence. Nothing to set up, no account, no monthly fee. It works offline, and it shows you what it's about to do before it does it.

A real session. knaif chose the tool and the settings; you saw the command before it ran.

how it works

You describe the outcome

No flags to remember, no manual pages. "Compress this under 25 MB", "get it ready for WhatsApp", "pull the audio out as mp3".

A small AI model works out the intent

Running on your machine. It picks the operation and the values — and that is all it does. It cannot run anything.

Code does the work

Ordinary, tested code builds the command, shows it to you, asks before it writes, and runs it. Same request, same command, every time.

Documents

why local

Nothing leaves your machine

No account, no API key, no upload. Your files and your words stay where they are.

Free, however often you ask

No subscription and no per-request charge. Wemeasured it against three premium agents — same results, at $0.

The same answer tomorrow

The command is built by code, not improvised. Ask the same thing next month and you get the same command.

It asks before it writes

Anything that changes a file needs your confirmation, and that gate is enforced in code — not left to the model's judgement.
