How it works
There is no web editor and no chat inside the app. Your AI uses Praxino's tools, and you keep the window open next to it.
Connect your AI
Praxino ships an MCP server that listens on 127.0.0.1 only, with a token unique to your Mac. It works with Claude Desktop, Claude Code, Cursor or any MCP client.
Ask for the video
Say what you want: the format, what to cut, which captions, which music. The AI imports, looks at frames and the transcript, and edits.
Watch and adjust
The preview updates with every step. Each AI action is a single ⌘Z. If a change isn't valid it isn't applied, and the AI is told what to fix.
Everything happens on your Mac: no accounts, no telemetry, no uploading your videos to any server of ours.
What it does
Edit by talking to your AI
It imports, cuts, removes silences, transcribes on your Mac with Apple's speech recognition and adds captions. It also places titles, transitions and colour, and exports.
Word-by-word captions
Animated captions that follow the voice, in five styles: highlight, pop, karaoke, reveal and box. Fix them by hand or ask the AI.
360 video
Opens equirectangular video and Insta360 .insv and .lrv files directly: it stitches both lenses with the camera's calibration and stabilises with the gyro. Virtual camera in natural, normal or tiny planet, with keyframes, or have it follow a subject, or yourself, with Vision.
Your activity data
Import .FIT files from Garmin and compatible devices and overlay speed, power, heart rate, map and elevation profile. They stay synced to the time you recorded, even after cuts and speed changes. Animated map and an end card with the ride summary.
Auto reel
Picks the best moments by image, camera motion and activity data. Cuts on the beat of your music, and the music ducks on its own when someone speaks.
Colour
Histogram, automatic suggestions for exposure, highlights and shadows, and white balance. Filters with previews and a before/after comparison.
Ready for social
Series styles so every video comes out consistent. Safe-zone guides for Reels, TikTok and Shorts, and export without music so you can add a licensed song inside Instagram or TikTok.
Pro keyboard editing
J, K and L to go back, pause and forward (repeat to go faster). I and O to mark a range. Q and W to trim the clip to the playhead and close the gap. Whatever the AI does, you can touch up by hand.
Why Praxino
Twelve mirrors, before cinema
In 1877, Émile Reynaud patented the praxinoscope in France: a drum holding a strip of twelve drawings and, at its centre, a prism of twelve mirrors. As it spun, each mirror reflected one frame and the eye saw a single moving figure, sharper and brighter than in the zoetrope.
In 1892 Reynaud took the idea to the screen with his Théâtre Optique, projecting the first animated films at the Musée Grévin in Paris, three years before the Lumière brothers' first show.
Praxino's icon is that device seen from above: the brass drum, the twelve frames with a bouncing ball and the mirror prism.
