AI transcription with uncertainty flags
Generate subtitles with AI, then work through the transcript with low-confidence words already marked for review.
SubtitleGenerator
SubtitleGenerator is a browser-based AI subtitle tool for generating, reviewing, styling, and exporting subtitles from local video files.
Overview
SubtitleGenerator is a browser-based AI subtitle tool for generating, reviewing, styling, and exporting subtitles from local video files. It is built around a fast correction workflow: the system flags uncertain words, then lets you fix, keep, or re-transcribe the parts that need attention before export.
The product supports a wide range of caption looks, including 33 styles across six families, and it offers subtitle workflows that can fit both social video and editing timelines. The site highlights no signup to start, common video format support, and a local-first approach where the uploaded video stays on your device.
Core features
Interactive subtitle correction
Edit subtitles in the browser by correcting words, keeping a cue, or re-transcribing only the part that is wrong.
33 subtitle styles
Choose from 33 caption styles across six families, with typography, framing, highlighting, and motion changing together.
Style and font preview
Preview styles on your own video and use curated open-licence fonts that are shown before you commit.
Browser-based export workflows
Export subtitles in the browser, with reviewed SRT available on Pro or Max and burned-in video mentioned as an output option.
Full-track translation on paid plans
Translate full tracks in the same editor on Pro and Max, while keeping the subtitle workflow in one place.
Where it fits
Quick subtitle cleanup for social video
A creator can upload a local clip, review the automatically flagged uncertain words, and export styled subtitles without setting up a separate desktop workflow.
Portable subtitles for an editing timeline
An editor can generate and review subtitles outside the timeline, download SRT on Pro or Max, and import the file into Premiere Pro or another compatible NLE.
Caption styling for different content types
Teams making videos with different visual treatments can choose from the style library to match tutorial, interview, gaming, lyric, or branded formats.
Transcript review before import
Users who want to check transcription quality before committing to a timeline can correct names, technical terms, and other uncertain cues in the browser.
Full-track subtitle translation workflows
Projects that need translated subtitles on paid plans can keep generation, review, translation, and export in one editor instead of using separate tools.
Pros and Cons
Pros
- No signup is required to start, which lowers the barrier to testing the tool.
- The editor flags uncertain words automatically, making transcript cleanup more focused.
- Subtitles can be corrected in browser without leaving the workflow.
- A large style library is available, with 33 styles across six families.
- The product supports a reviewed SRT workflow for editors using Premiere Pro and other compatible NLEs.
- Your video stays on your device according to the site copy.
Cons
- SRT export is tied to Pro or Max, so the free workflow is more limited for editors who need portable subtitle files.
- The site says SRT does not carry fonts, colors, position, or word-by-word animation, so designed captions need another workflow.
FAQ
Is there a free version, and what requires a paid plan?
Yes. The homepage states that you can start for free with no signup required, and the workflow happens in the browser. The site also notes that Pro and Max add full-track subtitle translation and that SRT export is available with Pro or Max.
What video files can I use, and does the video leave my device?
The product is browser-first and works from a local video file you upload. The site says your video stays on your device, and it supports common video formats including MP4, MOV, WebM, and MKV.
What can I do in the editor?
SubtitleGenerator can generate subtitles, flag uncertain words, let you edit or re-transcribe cues, translate subtitles on Pro and Max, apply one of 33 styles, and export subtitles in the browser.
Can I use the output in Premiere Pro or DaVinci Resolve?
The site describes a reviewed SRT workflow for Premiere Pro and other compatible NLEs. You can generate and review subtitles in SubtitleGenerator, export SRT on Pro or Max, and import the file into an editing timeline.
