Subtitles

Subtitles is an AI transcriber tool. A free, no-signup web tool that transcribes and translates video speech, then renders the subtitles back into the video file. All processing happens inside the browser, so recordings stay on the user's machine.

Subtitles by fframes is a browser tool that takes a video file, transcribes the speech, optionally translates it, and burns the resulting captions back into the video. The whole workflow runs locally in the browser tab, so the uploaded file and its audio never leave the machine. That design choice makes it an unusual entry in a category where most automatic captioning services upload media to a cloud queue and return a finished file minutes later. The process is short by intention: choose a video, let the transcription run, review or adjust the text, pick a translation target if needed, and export a new video with the subtitles rendered on top. Because rendering happens client side, the output is a downloadable video rather than a separate caption track or a shareable link, which suits people who need a finished file to publish, send or archive. The project is open source and the author lists a GitHub repository alongside links to Product Hunt, a personal Twitter account and a GitHub Sponsors page for funding development. The tool fits creators, editors and small teams who need quick captions without creating an account or handing footage to a third party. It is also a reasonable pick for anyone working with sensitive recordings, since nothing is transmitted to a server. Against paid captioning suites it trades extras for simplicity: there is no visible account system, no collaborative workspace and no listed API or third-party integrations on the homepage. It is best treated as a fast, private utility for single videos rather than a production captioning pipeline. Language coverage, model choice, file size limits and export formats are not documented on the homepage, so anyone with strict format requirements should test with a representative clip first.
