Instagram Reel to SRT Captions
Drop any saved reel, video, or audio file — Whisper AI transcribes it entirely on your device and hands you timestamped, editable subtitles. Hindi & Hinglish supported with Roman output. Free, unlimited, no signup, no watermark.
Save the reel to your device, then drop it below. Everything is processed locally — nothing is uploaded.
Best accuracy for Hindi/Hinglish. First use downloads ~200 MB (cached after). Runs fastest on Chrome/Edge desktop (GPU); on phones it works but is slower.
Exactly how your captions will read on a vertical reel
How it works
Drag any saved video or audio file into the studio — MP4, MOV, MP3, WAV and more.
Turbo for best Hindi/Hinglish accuracy. Choose the spoken language or auto-detect, and Roman or original-script output.
The AI model runs in your browser via WebAssembly or WebGPU. The audio is decoded and transcribed without a single upload.
Polish any cue in the editor, preview it on the reel mock, then download SRT or VTT — or copy the transcript.
Why on-device matters
Most "free" caption tools upload your video to their servers, where it can be stored, analyzed, or rate-limited behind a paywall. This studio is different: the Whisper model downloads to you, once, and every transcription after that happens inside your browser's sandbox.
- Unreleased client work stays under NDA — nothing leaves the device
- No per-minute caps, queues, or paid tiers — your hardware is the limit
- Model is cached after first use — later runs start instantly
- Works with sensitive footage: interviews, legal, medical, internal comms
Built for real workflows
Burn-in accurate captions in CapCut or Premiere — viewers watch 80% of reels muted.
Import SRT straight into Premiere Pro, Resolve, or Final Cut with frame-accurate timestamps.
Caption multilingual client accounts without per-seat SaaS fees or watermarks.
Make content deaf- and hard-of-hearing-accessible; export VTT for web players.
Pull quotable, timestamped transcripts from source video without uploading it.
Turn winning reels into blog posts, newsletters, and carousels from the TXT export.

Creators on the Reel → SRT studio
“I caption every reel in Hindi and English. The Turbo model nails my Hinglish, and the Roman output means captions read 'namaste doston' instead of Devanagari — perfect for my audience. My CapCut workflow went from 20 minutes to 3.”
“Client NDAs mean I can't upload rough cuts to cloud transcription services. This runs locally — I checked the network tab, nothing leaves the machine. SRT drops straight into Premiere with timestamps that actually line up.”
“We caption ~40 reels a week across Spanish and English accounts. Every 'free' tool we tried watermarked exports or capped minutes. This one is genuinely unlimited, and VTT export covers our web embeds too.”
“I recommend this to clients making their social content deaf-accessible. On-device processing also satisfies the privacy reviews most orgs require. I'd love speaker labels someday, but for clean single-voice reels it's superb.”
