SubtitleGen vs quso.ai (formerly Vidyo AI)

SubtitleGen turns uploaded audio and video into timed subtitles you can export for YouTube and other platforms. Upload a file, let it transcribe speech, then review or tweak captions in an online editor before downloading SRT, VTT, ASS, or TXT files.

Where a full video editor buries subtitles inside a timeline, SubtitleGen keeps the workflow narrow: transcription, caption editing, and translation in one place. Paid plans bundle AI translation at no extra charge, which matters if you publish the same clip in multiple languages without hiring a separate localization step.

The free tier gives you 30 credits and a 30-minute per-file cap, so you can test accuracy on a short clip before upgrading. Content creators, educators, and marketing teams use it when they need readable captions fast without installing desktop software.

quso.ai helps creators turn one long video into a batch of short, vertical clips with captions, reframing, and scheduling built in. The homepage headline promises one long upload can yield about ten clips in a single pass, and the product bundles clipping, subtitles, a text-based editor, and a social calendar instead of stitching together separate apps.

For podcasters and YouTube-first teams, the workflow matters as much as the headline. quso.ai imports from YouTube, Zoom, Twitch, Loom, and file uploads on the free tier, then scores moments for virality before you publish to TikTok, Reels, Shorts, LinkedIn, and X from one place. That end-to-end path is what separates it from clip-only tools that stop after export.

The site now presents quso.ai as the active brand while keeping Vidyo.ai URLs in circulation, which can confuse bookmarks but keeps legacy links working. Pricing starts free without a credit card, with paid plans from $29 per month across three tiers.
