Manual edits stay safe
Manual blocks survive re-transcribe and remain separate from auto-generated ones.
Subtitle repair, not just auto-captions
Turn rough transcripts into export-ready subtitles.
Subtitle Studio is built for the work that starts after transcription: review the weak lines, repair what Whisper got wrong, keep manual edits safe, preview styling live, and export without the workflow collapsing.
Weak lines surface fast
Risky subtitle blocks are marked for review instead of being buried in the full transcript.
Preview before export
Style, timing, and word highlight changes can be checked before you burn anything in.
Manual block aligned
Fix the weak lines,
keep the timing,
export when it feels right.

Preview parity
The product is already shaped around making preview and export behave the same way.
Why it feels different
Made for the part after transcription, where most tools get clumsy.
This is not just an upload form with a caption button. The product already centers on repair, focused editing, review signals, timeline control, styling, and export outcomes that need to hold together.
01 / Preserve
Manual fixes do not get flattened by the next transcription pass.
Add missing lines, split blocks, and protect the fixes you actually care about.
02 / Review
Weak subtitle blocks surface first instead of hiding in a “95% accurate” promise.
The review workflow is built around risky lines, repeated bad tokens, and block-by-block cleanup.
Needs review
03 / Preview
Style changes stay inside the same browser workspace as text and timing.
Fonts, colors, highlight behavior, position, and layout all live next to the transcript instead of in a separate tool.
04 / Finish
Projects, retries, logs, and exports are kept together instead of scattered across files.
That makes the app useful for repeat work, not only for a one-off caption job.

How it works
One repair loop from upload to final export.
Upload, review, repair, preview, export
1
Upload a clip
Start with a video, an optional project title, and a language hint if you already know it.

Language hint
2
Generate the first pass
Whisper creates the transcript while the project, timeline, preview state, and exports are prepared in the background.

3
Repair the weak parts
Focus risky lines, add manual subtitle blocks, fix repeated mistakes, and retime on the waveform when needed.
Needs review

Batch replace
4
Preview and export
Check styling live, then export subtitle files, burned captions, or a subtitle-only video layer.

For creators
Get from transcript to publishable captions without bouncing between tools.
Use presets, fonts, highlight styles, and export options in one place instead of patching the result together elsewhere.
Readable captions for social video
Fast style iteration
Export when the preview looks right
For editors
Keep what is good, isolate what is bad, and repair only the fragile parts.
The app already supports focused block editing, manual insertion, split/delete, timing adjustments, and block-level alignment improvements.
Focused block editing
Waveform timeline control
Manual repair workflow
For teams
Use a persistent project workflow instead of treating subtitles like throwaway exports.
Authenticated projects, pinned retention, font handling, recent history, retries, and logs make repeat work less chaotic.

Start with one video
Upload a clip, fix the weak lines, and leave with a cleaner final export.
Subtitle Studio already covers the full loop: transcription, repair, live preview, subtitle files, and burned caption video. The homepage should now look like a product worth trying, not a list of links.
