Quick answer
Yes — Captionly is a one-time-purchase alternative to Submagic. It costs $34 once, while Submagic runs $18–39/mo — about $216 per year, every year. Local Whisper auto-captions with karaoke word-highlight styles and ffmpeg burn-in export. It is for people who want the job done on their own hardware without a renewal date — not for teams that live inside Submagic's ecosystem.
The verdict
Switch to Captionly if you are an individual or small team paying Submagic $18–39/mo for work your own machine can do. Costs about one month of Submagic, then captions the rest of your clips for free.
Stay with Submagic if your workflow depends on its integrations, you need enterprise features (SSO, admin controls, SLAs), or your team is large enough that per-seat collaboration tooling is worth the bill. Captionly does not try to replicate those.

Where Submagic still wins
- Ecosystem and integrations. Established tools accumulate years of third-party integrations, templates and add-ons. If your workflow is wired into Submagic's ecosystem, switching means rebuilding that plumbing — a real cost.
- Team and enterprise features. Shared workspaces, granular permissions, SSO, audit logs and a vendor to call when something breaks — that is what the higher subscription tiers actually buy, and a pay-once app does not come with it.
- Familiarity and hiring. Submagic is the name people already know. Onboarding a team onto a tool nobody has used before takes time the subscription never charges for.
Where Captionly wins
- Price, permanently. $34 once versus $216/yr for as long as you use it. There is no renewal, no seat count and no tier gate.
- Local Whisper transcription. whisper.cpp with word-level timestamps; the engine and model download once on first run, then run fully offline.
- Karaoke word-highlight captions. Real ASS timing tags per word for the TikTok and Reels look, rendered by ffmpeg exactly as previewed.
- 3 style presets. Karaoke Highlight, Bold Center and Classic Subtitle, plus font size, position and highlight color controls.
The math
Costs about one month of Submagic, then captions the rest of your clips for free.
- After 1 year: Captionly has cost you $34 total — Submagic has cost $216.
- After 3 years: Captionly is still $34 — the subscription is at $648.
- After 5 years: Captionly is still $34 — the subscription is at $1,080.
Common questions
Is it really free on GitHub?
Yes — Captionly is MIT-licensed at github.com/bensblueprints/video-clip-captioner-mvp. The $34 buys the signed Windows installer; building from source is free.
Does my footage get uploaded?
Never. Captionly runs Whisper and ffmpeg entirely on your machine — your footage never leaves it, with no accounts or telemetry.
Does it do everything Submagic does?
No. Submagic's AI b-roll, auto-zoom and template marketplace are real value if you use them. If what you use is transcribe, pretty word captions and export, Captionly does that pipeline locally for one month's price.
