As answered by people managing ExtendsClass JSON Generator and PixScript.
PixScript's answer:
Next.js, Vercel, AI speech-to-text models for transcription.
PixScript's answer:
It covers YouTube, TikTok, and Instagram Reels from one tool as most competitors only handle one platform. And it exports SRT/VTT subtitle files, which tools like Tokscript don't offer at all. You also get timestamps on every plan, including the free tier.
PixScript's answer:
Tokscript only does plain text, no subtitle export. Otter.ai is built for meetings, not video URLs. Descript costs $24/month and requires uploading files manually. PixScript handles all three major video platforms via URL, exports SRT subtitles ready for any video editor, and starts at $9/month. The free tier gives you 10 transcripts a month.
PixScript's answer:
Content creators who repurpose video into blog posts and social captions. Video editors who need SRT subtitle files. Students who want text from lecture videos. Podcasters turning episodes into show notes. Basically anyone who needs text from video or audio without typing it out.
PixScript's answer:
I kept watching long YouTube videos just to grab a single quote or find a specific part someone mentioned. Copying from YouTube auto-captions was messy, and there was no easy way to export them as subtitle files.
So I built a tool that takes any video URL and gives you clean, timestamped text you can actually use.
