Interactive demo — filter lines, navigate, and place markers

Built for editors, not chatbots

Jam Marker sits in your AE workspace — link a layer, transcribe once, then work the timeline like a script.

Local transcription

Whisper runs on your GPU or CPU via faster-whisper. Footage never leaves your machine.

Search & jump

Filter every line, double-click to go, or step through hits with the playhead.

Smart markers

Label with first two words, full sentences, timecode, or rich metadata — your choice in Settings.

Timeline-aware

Maps source time to comp timecode — layer in-points, trim, stretch, and display offset included.

How it works

Three steps from raw footage to marked timeline.

Link your source

Select the footage layer in your comp or pick a file. Jam Marker syncs layer timing automatically.

Transcribe

One click runs ffmpeg + Whisper. Results are cached beside your media for instant reloads.

Mark the timeline

Click a line → Go + mark. Or label every sentence at once with All · 2 words.
