Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Timed for video,
not for reading.
An SBV file is a list of timed cues, each a comma-separated start and end time above its caption line. Converting turns those cues into a readable transcript, each line stamped with its start.

General Kenobi.
**[0:00:01]** Hello there.
**[0:00:05]** General Kenobi.
Everything you
actually need.
SBV cues in, a clean timed transcript out, with no server and no account anywhere.
It never leaves your browser
Your .sbv is read and converted on your own device. Nothing is uploaded to any server, ever.

Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
**[0:00:01]** Hello there.
**[0:00:05]** General Kenobi.
Cues to a transcript
Each cue keeps its caption text prefixed with its start time; the end time goes.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for SBV, so the page never drifts from what the converter really does.
