A product I built, by night
Tellback
Messy client feedback in. Dev-ready tasks out.
Tellback turns voice notes, screenshots and "it's broken" into clear tasks, with the page, the exact element and the console error attached, plus a prompt your coding agent can act on.

How I built it
From idea to a full SaaS in 11 days.
It started with a client project where feedback arrived as WhatsApp messages and screenshots. I built the tool I wished I had, with AI agents doing most of the typing. Tellback exports prompts for Cursor, Claude Code, Windsurf, Copilot, Bolt, Lovable and Replit.
