First of all congratulations to the Autosubtitles team. I just went through your landing page and the feature breakdown looks incredibly clean. I noticed in your FAQ that the video processing stays entirely local on the device and only the audio track goes to the server for transcription. Like this fantastic approach to keep data private. A question came to my mind about the export process. Do you handle the local video burning directly in the browser using WebAssembly or FFmpeg.wasm.... or does the browser canvas handle the video stitching during export?
And definitely dropping an upvote for this. Wishing you the best on the launch today, @davidee.

Thank you so much @taimur_haider1 , I really appreciate the kind words and the support.
And yes, exactly. The video itself never leaves the device. Only the extracted audio is sent for transcription, and then everything else is handled locally in the browser.
For the export process, it is currently done using canvas rendering together with Mediabunny for encoding and export handling. Keeping rendering local was a really important part of how I wanted to build the product from the start. Modern machines and even mobile devices are surprisingly powerful now, browsers have become incredibly capable for handling video workflows, and avoiding a full video upload makes the whole process much faster. You can go from importing a video to exporting the final result without waiting for large uploads or server side processing in the middle.
Really appreciate the upvote as well. Thank you 🙂
@davidee Thanks for the deep dive into the stack. Appreciate it. Canvas rendering with MediaBunny is a super smart move. It completely skips annoying server bottlenecks. I look at SaaS layouts all day. This local processing speed is actually your absolute biggest superpower.
Are we able to also edit the videos from it's transcript like @Descript or this product specialises in subtitles and captioning only?
AutoSubtitles
Hey@himani_sah1 Not yet. Right now the product is very focused on subtitles and captions specifically rather than being a full editor like Descript.
That said, I do already have work planned around that kind of workflow because I would like AutoSubtitles to eventually have some lightweight editing capabilities as well. Things like transcript driven editing (and other features like auto clips) are 100% in the roadmap!
For now though, the focus has been on making the subtitle and captioning experience as fast and polished as possible 🙂
Portrait captions — do any presets keep text above the TikTok bottom UI, or is it manual every time?
AutoSubtitles
Hey@novamaker01, very good question! Yep so I'm actually working on safe zones as we speak, so not quite at the moment.
However, we do have the ability to save custom presets which means you can save the position of your subtitle so whenever you re-apply that preset it'll be positioned correctly.
Congrats on the launch! Super clean concept! Subtitles are practically mandatory for short-form content now, so automation like this is incredibly useful. How does the AI handle audio with heavy background noise or multiple speakers overlapping?
The animated captions and viral preset styles are such a time saver — usually you'd spend hours getting this right in Premiere or CapCut. Really like that it's all browser based so there's no software to download. Would love to see it handle auto-placement too so captions don't cover faces or subtitles.
