♿ Accessibility AI
🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.
Built for accessibility and compliance teams, e-learning and media platforms, public-sector web teams.
Why this exists
Accessibility work — captions, transcripts, alt-text, audio versions — is manual and slow, and the AI tools that help are scattered across separate captioning and TTS vendors.
What you get
One API key transcribes media, generates SRT/VTT captions, writes image alt-text, and voices text — the accessibility toolkit for WCAG/ADA/EAA compliance.
