Scored from public evidence (GitHub, Hacker News, release activity, free access), rebuilt 27 Oct 2026. Method.
Ranked by evidence — GitHub stars, Hacker News mentions, Wikipedia readership, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ Free, runs fully offline, and remains the accuracy benchmark that most commercial transcription services are measured against.
− No speaker diarization out of the box, it hallucinates text during silence, and large models are slow without a GPU.
+ The most capable free editor for short-form, with TikTok-native templates and captions.
− Features keep migrating behind Pro, and its ByteDance ownership raises data and availability concerns in some regions.
+ Eye-contact correction and lip-synced dubbing work well on phone-shot talking-head video.
− The subscription is expensive relative to CapCut and many effects feel gimmicky.
+ Strong accuracy plus built-in audio intelligence (speaker labels, chapters, PII redaction) and LeMUR for asking questions of a transcript.
− No consumer app, and per-hour pricing adds up on high volumes compared with self-hosted Whisper.
+ Strong team collaboration and brand kit features for a browser editor.
− Exports are watermarked and capped at 720p on the free plan.
+ The option to upgrade any file to a human transcript gives you a guaranteed-accuracy path for legal or published work.
− AI transcripts cost more per minute than pure-API rivals, and human turnaround can take hours to days.
+ Deleting a word from the transcript deletes it from the audio, and Studio Sound removes room echo and noise in one click.
− Studio Sound can make voices sound processed, and the desktop app is heavy on large projects.
+ Accurate auto-subtitles and a broad toolset without installing anything.
− Browser rendering is slow for long projects and the free plan watermarks exports.
+ Generous free minutes and a solid editor for tweaking clips after auto-selection.
− Clip selection quality is inconsistent on multi-speaker or non-English content.
+ Very simple link-in, clips-out workflow with good automatic reframing.
− Limited editing control and no free tier beyond a trial.
