Sisyphos · Editorial reasoning engine
You shot for hours. Sisyphos watches every frame, finds the moments worth keeping, and lines them up as a first cut you can open and change.
Every pick comes with a reason. Every reject, too. You stay the editor.
For macOS · In development
For anyone who shoots far more than they use.
Before anything is judged, every clip is measured on your Mac across five signals, from motion to technical quality. Motion and sound, ten times a second, first frame to last.
Then Sisyphos selects and trims. Every reason it gives comes from these measurements.

01Motion
Subject and camera, measured apart.
Movement in the frame is split into subject motion and camera moves.
02Audio
Energy, peaks and onsets.
Where the sound hits, and how loud the clip really is in LUFS.
03Beat
Where the beat lands.
Cut points snap to real hits in the sound. Never at fixed intervals.
04Aesthetic
How good the image looks.
Every keyframe gets an aesthetic score from an image model, on your Mac.
05Technical
Focus, exposure and shake.
Shaky moments are dropped, and the reason goes on record.
Every clip · first frame to last
Every frame watched.
Every measurement is stored, so every decision can be explained.
06Footage
The whole shoot, clip by clip.
Every clip goes through the same measurements, first frame to last.
07Shortlist
The strongest moments go forward.
Near-duplicates drop out. When two moments overlap, the stronger one stays.
08Trim
Each one trimmed toward its best second.
In and out points land on a beat, a shot change or a quiet dip.
09Picks
Every pick comes with a reason. Every reject, too.
The AI judge rates each one and writes down why, in plain words.
Illustrative values · stills from a skate session
Every clip Sisyphos considered is on the record, including the ones it dropped, and why.
Ask “why isn’t this moment in my cut?” and you get an answer, not a shrug.

Same footage, same cut
The same footage with the same settings produces the same cut, every time, and you can verify it.

Local-first
All analysis runs locally. Only the final rating step sends a few still images plus the measurements to the AI, through your own key.
Into your timeline
Everyone else gets standard FCPXML and EDL exports. All three link your original files at the right timecode. Never proxies.
“Perpetual, because it runs on your machine.”
Sisyphos works on your footage, on your hardware. So you own it, the way you own your lenses.
Footage you’ve already analyzed never costs you again. Sisyphos remembers its answers instead of buying them twice.

No. Your video files stay on your Mac. All analysis runs locally. Only the final rating step sends a few still images plus the measurements to the AI, and the app technically can’t send more: every outgoing file is checked, and anything that isn’t a still image is blocked before it leaves.
With your own Gemini key, those stills go to your Google account under your data terms. Not through our servers. We run no cloud.
DaVinci Resolve gets a one-click push: Sisyphos builds the timeline in your running Resolve Studio via the scripting bridge. Everyone else gets standard FCPXML and EDL (CMX3600) exports. All three link your original files at the right timecode. Never proxies.
A Mac. Apple silicon is recommended: perception is compute-heavy and caches aggressively, so the first pass over a card is the slow one and everything after is instant. Windows is on the roadmap; tell us on the waitlist if that’s you.
Cents per clip, with a hard cap. Footage you’ve already analyzed is never billed again. Sisyphos remembers. You see every cent in your own Google console.
No. An auto-editor hands you a finished opinion; Sisyphos hands you an argument: every pick has axes, a rationale, and a ledger row, and every reject has a reason. It assembles the first cut; you stay the editor.
