ChatMap: turn podcast mentions into a shareable map

Auto-organize places mentioned on podcasts and niche channels into shareable maps

Problem

A long-time listener of a food podcast says every episode covers restaurants and dishes, they plan to visit "next time," and two days later can't recall which episode or which shop, while digging through episodes is painful. Someone finally built the map by hand. The same loss happens across countless niche podcasts and communities.

Solution

A self-serve tool where hosts or fans upload episode audio/transcripts or channel posts; it extracts shop names, locations and reasons, and generates a shareable interactive map filterable by episode and city, which the host can claim and keep updating.

Users

Podcast hosts, niche community operators, and their listeners/members

MVP

Upload audio or transcripts; auto-extract places and recommendation reasons; shareable map link; filter by city and episode; one-tap publish after review

Revenue

Monthly subscription for hosts (custom domain and branding), free for listeners; affiliate revenue from delivery or reservation links

Why now

Long audio and group chats accumulate rich local knowledge but mapping is still manual; transcription and extraction costs dropped sharply, making a vertical map generator a weeks-long solo project.
