Swap the top and bottom text blocks in bilingual SRT subtitles — structurally, without language detection or guessing.
Fix SRT subtitle timing with precise offset, FPS conversion, and two-anchor drift correction. Deterministic, local, and fail-safe — no AI guessing.
Turn a script into a vertical narrated short with voice and subtitles that light up word by word. Speech recognition recovers the timings from the generated audio, so captions never drift when you change the voice, the speed, or a line.
Check SRT files in batches, get cue-level QA reports, and export conservative repair copies while preserving your originals. Includes explicit time shifts, overlap trimming and two-line track splitting. English edition. Python 3.10+; no API key needed for the local engine.
Batch validate, clean, normalize, swap, and convert subtitle files with deterministic processing and failure-safe reports.
Check existing SRT subtitles for timing errors, overlaps and readability warnings. Get source-linked HTML, Markdown and JSON reports plus an optional format-only normalized SRT. Python 3.10+, no third-party packages or script API key. No transcription, translation or automatic retiming.
Enforce consistent names, terms, and recurring corrections across SRT subtitles using your own glossary. Review matches before applying changes — deterministic, local, and no AI guessing.
A free retention check for one published short video: paste your average percentage viewed and get a PASS / REWORK / REBUILD verdict with the threshold shown, plus the single biggest retention leak named and one concrete fix.
A free single-file tool that tells you whether a short-form script fits your target length before you record it. Open the HTML in any browser - no install, no signup, no API key, no coding tool of any kind. Paste your script and get the estimated spoken length, a per-line breakdown marking your first cuts, a hook-length check, a warning for lines too long to read as captions, and a stopwatch that measures your own pace and recalibrates to it. Runs offline; your script is never uploaded.
