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.

It depends on what subset of Notion you use. Nothing (including Notion) is perfect for me. I'd like to build my own eventually, but I'm currently using Obsidian which doesn't hit your "works in the browser" requirement. One option, which is open source and self hosted, is Trilium[sic], found at https://github.com/zadam/trilium It's open source, so if it's close to what you want, you might be able to adjust it to... - Source: Hacker News / over 1 year ago
I can also recommend Trilium Notes [1], which I have been happily using for years. It's currently in "maintenance mode", which I personally see as a feature (no risk of bloatware). Self-hosted, great webapp, optional native clients and works offline. https://github.com/zadam/trilium. - Source: Hacker News / over 1 year ago
Tried Obsidian for a while, loved a lot about it, but....mmm. Obsidian out of the box is a bit limited; plugins are great and add tons of features, but then you start hitting issues with plugin maintainers abandoning plugins you rely on, or needing to make a decision between three different plugins that all do the same thing slightly different. Depending on your use case and expectations that may not be a big... - Source: Hacker News / over 2 years ago
I move between machines a lot and prefer an online tool; I'm self-hosting Trilium Notes https://github.com/zadam/trilium ; this looks a bit cleaner but without syncing (or server-side storage) it misses a bunch of potential use cases. - Source: Hacker News / over 2 years ago
