Site Tour

stsqz.com is the official site of the sts Team. The team formed in November 2025 with 14 members, and every AI tool on the site runs locally in your browser - files are never uploaded to a server. This tour walks through the whole place, corner by corner.

Tools & the lab

lab.stsqz.com - the local AI lab

Three promises: your data never leaves your device, it stays free, and it works offline. Five tools; models download only when you need them:

• Speech to Text lab.stsqz.com/transcribe - audio to timestamped text, SRT subtitle export, three model tiers
• Text Recognition lab.stsqz.com/ocr - pull copyable text out of images, fully local OCR
• Background Remover lab.stsqz.com/rmbg - keeps the subject, makes the background transparent, outputs PNG; best on portraits
• Audio & Video lab.stsqz.com/audioconvert - full ffmpeg in the browser: convert, trim, compress, concatenate, burn subtitles; you type parameters like a terminal

For advanced Audio & Video usage see the /manual handbook: 20 chapters covering parameter reference, filters, troubleshooting, and a glossary.
