Live Captions by Subanana
Summary
Subtitle files that drift out of sync, transcripts where speaker turns blur together, and live event captions that drop out mid-sentence — these are the production failures that Live Captions by Subanana is built to prevent.
The tool covers four distinct workflows under one interface: video subtitling with glossary enforcement, verbatim transcription with word-level speaker separation, meeting capture without requiring a bot to join the call, and live captioning for in-room or public-display audiences across 95+ languages. Dual ASR engines run per language pair with millisecond timecodes, and custom glossaries correct terminology before translation — each substitution logged. Export options include SRT, VTT, FCPXML, XLSX, Markdown, and burned-in video up to 4K. The free tier caps projects at 15 minutes, which surfaces the wall fast for anyone processing long-form content. No API is available, so teams that need to wire this into an existing pipeline hit a dead end and look elsewhere.
Bottom line: Pick this for subtitle and transcript work where glossary accuracy and multi-language export to spec are the deliverable — plan a different stack when your workflow requires API access or automated pipeline integration.

Pros
Sign in to edit- Dual ASR engines run per language pair with millisecond timecodes and silence recovery, so the exported file stays frame-accurate even when audio quality dips between speakers.
- Glossary enforcement corrects domain-specific terms before translation and logs every substitution, which means brand names, product terms, and specialized vocabulary survive the language switch without a manual review pass.
- Word-level speaker diarization splits overlapping voices at word boundaries and carries named roster labels through every export format, so a two-hour interview with four speakers arrives as a quotable, attributed transcript rather than an undifferentiated wall of text.
- Export covers SRT, VTT, FCPXML, XLSX, Markdown, and burned-in video up to 4K, which means the same processed file hands off to a video editor, a data analyst, and a publishing workflow without conversion steps.
- A no-bot browser extension captures meetings without joining as a participant, so teams whose platforms block third-party bots can still get a transcript without requesting IT exceptions.
Cons
Sign in to edit- The free tier caps each project at 15 minutes, so a 90-minute interview or a two-hour event recording hits the wall on the first upload — teams processing long-form content regularly are immediately into paid territory and need to budget accordingly before starting.
- No API is available, which means every file requires a manual upload through the web interface. Teams that generate transcription jobs programmatically — automated ingest pipelines, post-production workflows triggered by a CI step — cannot integrate this tool and move to a competitor that exposes an endpoint.
- Live captioning and meeting transcription depend on a stable connection to the Subanana service with no self-hosted option, so organizations under strict data-residency requirements or operating in environments where outbound connections to third-party SaaS are restricted cannot deploy this tool.
