Free video tools that never upload your files
Single-file video tools that run entirely in your browser. The AI models download to your computer and process the video there, so there is nothing to sign up for, no watermark and no server ever sees your footage.
Why these tools run in the browser
Most free online video tools upload your file, process it on a server and send the result back. That is slow for large files, it is why so many of them cap the length or add a watermark, and it means the footage sits on somebody else's disk. These tools use the video decoder built into your browser and open AI models (Whisper for speech, Florence-2 for pictures) running through WebGPU or WebAssembly. Once a model has downloaded, you can disconnect from the internet and they keep working.
When one file at a time is not enough
They are built by the team behind Reelary, a desktop app that does the same things across a whole footage library: it transcribes and describes every clip, lets you search all of it by meaning ("drone shot of a coastline at sunset", or a line someone said), and assembles the results into a cut. It also runs entirely on your own machine. Download Reelary free for Mac or Windows, or read how local AI video search works.
