ThreadRecap

ThreadRecap turns WhatsApp chat exports into structured, defensible records: summaries, timelines, decisions, commitments, and evidence packets. Used by solo professionals and individuals who need to show what was actually agreed: disputes, HR and compliance, partnership audits, custody, rentals, sales post-mortems. Available in English, Portuguese, Spanish, German, Italian, and French. Paying customers across 20+ countries, acquired almost entirely through organic search.

Why people pay ThreadRecap

ThreadRecap has built a multilingual library of WhatsApp export help content that already ranks and pulls organic traffic across 20+ countries. A fresh copy starts with no search presence. Users who have uploaded sensitive dispute or HR chats and generated reports have history they would not want to recreate elsewhere.

Product complexity
Low
A web app that parses WhatsApp exports, transcribes audio and generates structured reports.
Data
Low
All content comes from the customer's own WhatsApp export; no external data sources are needed.
Integrations & infrastructure
Moderate
Notion, Trello and Google Calendar connections extend the product for meeting and project use cases.
Human operations
Low
Processing is automated end-to-end; no human review or manual steps are involved.
Regulation / hardware
Low
The tool produces summaries for personal use; it does not give legal advice or act as counsel.
