ThreadRecap
ThreadRecap turns WhatsApp exports into structured, timestamped reports you can act on or hand to someone else.
What it does
Who it is for
Solo professionals in real estate, HR, recruiting, law and client services who need a defensible record of what was agreed, plus anyone catching up on long work, family or community threads.
How it works
Export the chat from WhatsApp, upload the .zip or .txt, choose an analysis goal, get the report in seconds. No setup, no integration, no account for the other participants.
Pricing
Credit packs with no subscription required, plus an optional monthly plan for regular use. Free credits on signup.
Languages
English, Portuguese, Spanish, German, Italian and French.
Independent and bootstrapped, launched in January 2026.

ThreadRecap's answer:
Most summarizers expect you to paste text. ThreadRecap takes the raw WhatsApp export, the .zip with thousands of messages and voice notes, and turns it into a timestamped record you can hand to someone else. Voice messages are transcribed and merged into the same timeline as the text, so a commitment made in a 4 minute audio at 11pm sits in date order next to everything else. The output is not a paragraph of prose. It is decisions, agreements, deadlines, responsibilities and quoted messages, in chronological order.
ThreadRecap's answer:
Generic AI assistants can summarize a chat you paste, but they hit token limits on long threads, ignore voice notes, and give you a different structure every time you ask. Chat statistics tools give you word clouds and message counts, which is not what you need when you are trying to prove what was agreed. ThreadRecap is built for the specific job of turning a full export into a structured, repeatable record. It works in six languages, needs no integration or account for the other participants, and you pay per analysis instead of subscribing.
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.

The visual patching part of Max makes sense when you know the history of the program. It was built for musicians working at the forefront of interfacing MIDI with the power of the more compact mainframe computers of the day (PDP-11 IIRC). The 'programming' was done through a GUI running on the first Macintosh. At first there was no audio processing in Max itself, it was purely for generating and manipulating MIDI... - Source: Hacker News / 3 months ago
SuperCollider has a longer DSP feature list and a more powerful language. The dealbreaker was deployment: scsynth is a separate process. Shipping a game app that has to spawn and supervise another OS process, on iOS, with sandboxing and lifecycle quirks on top, was more friction than I wanted. libpd, by contrast, runs embedded in the game process. - Source: dev.to / 4 months ago
At this point, we can produce the array of pitches that are midi notes. To create sound from these notes I've used a specialized programming language called SuperCollider. I won't dive much into details here, but you may have a look at the code if you're interested. Beware, there are quite a lot of branches there and all of them contain some interesting code. - Source: dev.to / about 2 years ago
This is essentially sound design from first principles. There's a good book here: https://www.amazon.com/Designing-Sound-Press-Andy-Farnell/dp/0262014416 Note that the software used (Pure Data) can be replaced by another high-level language (SuperCollider: https://supercollider.github.io/) pretty easily. I know of no "tool" to do what you want because there are few things that are universal to different kinds of... - Source: Hacker News / about 2 years ago
Since then, I've been working more and more with TidalCycles. TidalCycles is an open-source live coding framework for creating patterns written in Haskell. TidalCycles uses SuperCollider on the backend, another language I've been using for live coding. Recently, I started using Tidal Looper for live vocal processing. This blog post will walk you through what you need to get started with vocal looping with Tidal... - Source: dev.to / over 2 years ago
