AI captions that transcribe, translate and export in minutes
Beginner
What is SubtitleGen?
SubtitleGen is an online AI subtitle generator that transcribes video and audio, produces editable captions and translates them into multiple languages, then exports formats such as .srt. It runs in the browser with no install, accepts major media formats, and offers a free starting quota before you subscribe.
SubtitleGen is a browser based subtitle and transcription service aimed at creators who publish video across more than one language. You upload an audio or video file, the platform transcribes the speech automatically, and it returns timed subtitle lines you can review before exporting. The vendor claims accuracy of up to 99.8 percent and says files are processed in seconds to minutes depending on length and size. No installation is required; the whole workflow runs in a web browser on any device. The practical loop is four stages: upload, auto-generate, review, export. The review stage matters most, because automatic transcription still benefits from a human pass, especially with overlapping speech, heavy accents, background music or specialist vocabulary. An in-browser editor lets you correct wording, adjust line breaks and fine-tune timing. Translation is built into the same flow, so a finished transcript can be pushed into other languages without a separate tool. The site lists English, Spanish, French, German, Italian, Portuguese, Japanese, Chinese, Korean, Dutch and Turkish, with a dedicated languages page for the fuller set. Export produces standard subtitle files such as .srt that drop into YouTube or an editing timeline. Who it suits: solo YouTubers and course creators who want captions without a manual transcription pass, small teams localising a back catalogue, and social media producers who need burned-in or sidecar captions quickly. It is also a reasonable fit for accessibility work, where accurate captions are a requirement rather than a nice extra. Where it sits: the field is crowded, with dedicated captioning tools, general transcription services and built-in editor features all competing. SubtitleGen's pitch is the combination of transcription, translation and a lightweight editor behind one login, with no software install and a free starting quota so you can judge output quality on your own footage before committing. It is not a full video editor, so expect to finish the job elsewhere. For teams handling confidential material, the privacy and security claim on the site is worth verifying against your own requirements before uploading sensitive content.
How do you use SubtitleGen?
1Create an account and claim your free quota
Start at the signin page with the Start For Now link. New users get a free usage quota, which is the sensible way to test accuracy on your own recordings before any subscription.
2Upload your video or audio file
Drag in or select the media you want captioned. The service accepts major formats such as MP3, MP4, AAC, WAV, FLAC, M4A, OGG and WEBM, so conversion is rarely needed first.3Let the AI generate the transcript and subtitles
The platform transcribes the speech and produces timed subtitle lines automatically. Processing time depends on file length and size, and the site describes turnaround in seconds to minutes.4Review and correct in the online editor
Open the subtitle editor and fix misheard words, split long lines and adjust timing. This pass is what separates usable captions from raw machine output, and it is where most of your effort will go.5Translate into additional languages
Using the same project, generate subtitle versions in other languages. The homepage lists English, Spanish, French, German, Italian, Portuguese, Japanese, Chinese, Korean, Dutch and Turkish, and the languages page covers the wider set.
6Export subtitles for your platform
Download the finished file in a format such as .srt and bring it into YouTube or your editing software. Check sync on the final platform, since player behaviour can differ slightly from the preview.
Pros and cons
Pros
- Handles transcription, caption editing and translation in one browser workflow, so a single file can serve several language audiencesAI
- Accepts all major audio and video formats including MP3, MP4, WAV, FLAC and WEBM, which reduces pre-conversion workAI
- The in-browser subtitle editor lets you fix wording and timing before export rather than accepting raw outputAI
- Exports standard subtitle files such as .srt that slot into YouTube and common editing timelinesAI
- No software to install and a free usage quota at signup, so output quality can be tested on real footage firstAI
Cons
- Accuracy is advertised as up to 99.8 percent, but that figure will not hold on noisy audio, crosstalk or heavy accents, so a manual review pass is still part of the jobAI
- No pricing figures appear on the homepage, and the subscription tiers, quotas and per minute limits are not disclosed before you sign upAI
- Subtitle translation quality in less common language pairs is not evidenced on the site, and spot checks are advisable before publishingAI
- It is a captioning tool rather than a video editor, so timing, styling and burn-in still need a separate editing applicationAI
- Nothing on the homepage documents an API, bulk upload or team features, which limits appeal for high volume or automated pipelinesAI
