As answered by people managing AudioPen and ThreadRecap.
ThreadRecap's answer:
Single-message transcribers make you forward voice notes one by one and lose the order of the chat. Generic AI assistants hit limits on long threads and ignore voice notes. Chat statistics tools give word clouds, not what was said. ThreadRecap handles the whole export at once and keeps sender and time on every line. The export opens free in the browser, the exact price shows before paying, and you pay once per conversation, with no subscription.
ThreadRecap's answer:
Solo professionals and individuals who need to establish what was actually agreed in a conversation. In practice: real estate agents, recruiters and HR, small business owners, freelancers dealing with clients, and people documenting a personal dispute over a rental, a partnership or a family matter. A second, lighter audience uses it to catch up on long work or family group chats. Buyers are spread across more than 20 countries, led by the UK, the US, Italy and Switzerland.
ThreadRecap's answer:
It started as a personal tool. I kept receiving long voice notes and endless work threads, and wanted the main points without listening to everything again. I built the first version over a weekend and published it as a proof of concept, mostly to see whether anyone else cared. People did, but not for the reason I expected. Instead of catching up on chats, they were using it to document disputes, prove agreements and produce a record of what was said. That reframed the whole product, and the roadmap has followed the users ever since.
ThreadRecap's answer:
Next.js and React with TypeScript, Tailwind CSS, Node.js on the backend, deployed on Vercel. Voice note transcription uses OpenAI Whisper, analysis runs on large language models, and payments go through Stripe.
ThreadRecap's answer:
Most tools transcribe one voice message at a time, or summarize text you paste. ThreadRecap takes the raw WhatsApp export, the .zip with thousands of messages and hours of voice notes, and writes out every voice message where it was sent, so the whole conversation reads as one dated record. A commitment made in a 4-minute audio at 11pm sits in date order next to everything else. On top comes a summary of decisions, commitments and open questions, and the record downloads as PDF and TXT.
