Why we bundled video tools

Video tools are the most expensive specialty category — Submagic alone is $16-50/mo, then add a video compressor, a trimmer, a captioner. Apexkit ships one set of tools that cover the 80% case: Auto-Subtitle Generator runs OpenAI Whisper for SRT/WebVTT output, our compressors and trimmers are client-side via WebCodecs, and a Replicate-hosted ffmpeg pipeline handles heavier conversion jobs. Everything is included — no per-minute usage fees as long as you stay inside your tier's pack budget.

Frequently asked

How accurate is the auto-subtitle?
OpenAI Whisper large-v3 — same model the specialist captioning tools use under the hood. Word-level accuracy is ~95-98% on clear English audio, ~92-95% on Indian / African / European-accented English, and good but lower (~85-92%) on heavy background music.
Burn the subtitles into the video, or sidecar SRT?
Both. We export the SRT/WebVTT files for upload to YouTube/LinkedIn (recommended), and offer a burn-in option for TikTok / Reels where platforms don't support upload sidecars.
