What this workflow does

The workflow receives text or voice input via Telegram, applies AI analysis with OpenAI models and memory to parse parameters, then writes verified records directly into Postgres and Supabase.

It serves sales, marketing, and recruitment teams that need automated data capture from messaging channels into reliable database storage.

Who is this for?

Sales development reps, growth marketers, and small teams running outbound campaigns who want automated lead intake from chat.

What problem it solves

Turning ad-hoc voice or text requests into clean, verified prospects stored in a database is manual and slow.
