Upload your MP4, auto-generate captions with AI, correct the text, style and position subtitles, then render a finished video with burned-in captions. Works for TikTok, Reels, Shorts, and any format. No watermarks. No storage. Your files are deleted the moment you download.
Most subtitle editors either watermark your output, store your footage, or make you fight a bad AI transcript. SubForge auto-generates captions with Whisper AI, lets you fix every subtitle, and burns them permanently into your MP4 and then deletes everything.
Upload a video and move straight into caption generation without a bloated workflow.
Edit wording, timing, and grouping before you commit the final render.
Choose from curated fonts, clean presets, and exact on-screen subtitle placement.
Burn subtitles into the final MP4, download it, and retain nothing on the server.
No complex timeline editor. No render queue you can't see. Upload, fix the transcript, pick a style, and download a finished MP4 with burned-in captions.
Drop your video in and preview it instantly.
Clean up text, timing, punctuation, and subtitle grouping.
Choose fonts, size, safe-zone placement, and subtitle treatment.
Render the finished video and auto-delete all temporary files.
The workflow is designed around non-retention. Upload, process, preview, render, download, delete. That makes the product easier to trust for client work, internal content, and sensitive footage.
Used by content creators, social media agencies, podcast clip editors, and marketing teams who need burned-in captions on TikTok, Instagram Reels, and YouTube Shorts, without storing footage on a third-party server.
A subtitle tool that does exactly what you need and nothing you don't. No bloat, no stored footage, no watermarks.
