CueForge is a subtitle and caption editor that runs in the browser. Everything happens on your device. The files you open, including audio you transcribe, never get uploaded. The only network calls it makes are a Pro licence check and a cookieless page-view count.
The free tier reads and writes SRT, WebVTT, SBV, and ASS/SSA in both directions, and it handles QC checks, file repair, timing shift and retime, cue-by-cue styling, and authoring from scratch. No account required.
Pro is $99 a year or $12 a month, with a 7-day trial. It adds the broadcast and platform formats: SCC (CEA-608), MCC (CEA-708), EBU-STL, TTML, iTunes iTT, and EBU-TT-D. You also get frame-rate conversion, drift correction, audio auto-resync, QC compliance reports as CSV or printable output, custom QC presets, and batch conversion of a folder into a ZIP. On-device transcription produces a timed, word-aligned draft that you then edit by hand.
Before any conversion, CueForge shows a loss matrix for that specific format pair, so you can see what data will not survive the round trip. The built-in QC presets cover Netflix (Latin and Arabic), YouTube, and a generic profile. Right-to-left and bidirectional text, including Arabic and Hebrew, is carried through the whole pipeline.
Compliance QC, with a report
Reading speed, durations, gaps, overlaps and line length, checked against verified Netflix presets or a baseline you tune โ every QC pass runs free. Auto-fix the safe ones, then export a CSV or printable report to sign off a delivery
Style-preserving conversion
Colour, positioning, italics and line breaks survive the round-trip, with a live loss matrix that shows exactly what each target keeps before you convert.
Broadcast & OTT formats
SCC (CEA-608), EBU-STL, TTML/IMSC, Apple iTT, MacCaption MCC (CEA-708) and EBU-TT-D, imported and exported with styling and timing intact. Validate the export against your platform's spec before delivery.
Arabic & RTL, bulletproof
Right-to-left text, bidi and shaping handled correctly end-to-end, with QC rules written for Arabic, not bolted on.
Two things, really. Nothing you open ever leaves your machine: conversion, QC, and even transcription run locally in the browser tab, so subtitle files for embargoed or NDA'd content stay on your device. And before any conversion it shows a loss matrix for that exact format pair, spelling out which styling, positioning, and timing data will survive and which won't. Other tools convert silently and let you discover the damage in review.
Against upload-based web converters, the case is privacy plus honesty about loss; your files stay local and you see what a conversion drops before you run it. Against desktop editors like Subtitle Edit or Aegisub, it's zero install with broadcast delivery built in: SCC, MCC, EBU-STL, TTML, iTunes iTT, and EBU-TT-D, with QC presets for Netflix and YouTube specs and compliance reports you can hand to a client. The free tier covers SRT, WebVTT, SBV, and ASS work without an account.
Freelance subtitlers, captioners, and localization professionals who deliver to broadcast and streaming specs, plus video editors and small post-production teams who need occasional format conversion or a QC pass without buying enterprise captioning software.
Subtitle work has quietly hostile tooling. The common web converters upload your files to someone's server, and most tools convert between formats without telling you what got destroyed along the way. CueForge started from those two annoyances: build an editor where files never leave the device, and be upfront about exactly what each format conversion loses instead of pretending the round trip is clean. QC came next, because checking against a delivery spec by hand is the least fun part of the job.
TypeScript and React, built with Vite. The heavy work (batch conversion, audio resync, transcription) runs in Web Workers, with speech recognition running fully on-device via WebAssembly. Hosted on Cloudflare.
