A privacy-first, open-source macOS notepad that transcribes and summarizes your meetings entirely on-device — no meeting bots, no cloud APIs, and no audio ever leaving your Mac.

Hyprnote is a local-first AI notepad for meetings, built by the team at fastrepl and launched through Y Combinator's Summer 2025 batch with a Launch HN on August 11, 2025. The premise is simple and unusually strict about privacy: it listens to a meeting through both your microphone and your Mac's system audio, transcribes it, and writes a summary — and it does all of that on the device by default, with no Zoom/Meet bot joining the call and no audio sent to a remote server. You take rough notes during the conversation and Hyprnote turns them, plus the transcript, into a cleaned-up, context-aware summary afterward.
The on-device stack is the whole point. Transcription runs on a local Whisper model, and the summarization runs on HyprLLM, the team's small proof-of-concept model fine-tuned from Qwen3 1.7B — so a standard meeting is captured and summarized without a network round-trip. If you want more capable summaries you can bring your own LLM: Hyprnote can point at a local runtime like Ollama or LM Studio, or at a cloud API key (OpenAI, Anthropic, Gemini, OpenRouter) when you explicitly choose to. It's extensible too, with a VSCode-inspired plugin architecture and integrations for things like Apple Calendar and Obsidian, so notes land where you already work.
Hyprnote is open source (its code is public on GitHub) and free to run with local models; a paid cloud tier adds hosted models and team features for people who want them. It targets macOS — the download offers Apple Silicon and Intel builds, and it requires a recent macOS version (Sonoma or newer; check the official site for the exact minimum, which has shifted across releases). One honest note on naming: the project has evolved since launch — the original hyprnote.com now redirects to the team's commercial product, and the open-source app is continued under the name Anarlog (MIT-licensed) at anarlog.so. If you're evaluating "Hyprnote," that's the lineage you're looking at.
The honest framing: Hyprnote is a private meeting recorder and summarizer, not a content tool. It gives you an accurate, on-device record of what was said and a tidy summary of it — and it stops there. It writes no post, cuts no clip, designs no carousel, holds no brand voice, and publishes to nothing. The notes are for you; turning any of them into public content is a separate job.
Hyprnote's output is a private internal artifact: an accurate transcript and a clean summary of a meeting that, by design, never touched the cloud. That's exactly the raw material a founder, coach, consultant, or agency owner is sitting on — a webinar you just ran, a customer interview full of the exact language your buyers use, a strategy call where you said the smartest thing you'll say all week. None of it is content yet. It's a wall of notes only you will ever read. Kompozy is the layer that turns the shareable parts of that meeting into finished, on-brand posts. You decide what's public, paste the transcript or summary in as a source, and Kompozy generates the outputs Hyprnote can't: a Blog Article and an Email Newsletter written from the discussion, the three sharpest lines pulled into Quote Graphics and a brand-exact Carousel via HyperFrames, and native Text Posts for LinkedIn and X — every piece governed by your Persona Brief so a raw meeting transcript comes out sounding like your brand, not like a court reporter.
The pairing keeps a clean privacy boundary. Hyprnote holds the full, sensitive recording locally; Kompozy only ever sees the slice you deliberately hand it. And because Kompozy also generates net-new video, the same meeting insight can ship as a talking-head clip you never had to film twice — a Persona Short or a HeyGen avatar video with a face-locked recurring identity that reframes to 9:16, 1:1, and 16:9. From one hour-long call you keep the private record in Hyprnote and fan a week of scheduled content across the eight social platforms plus a blog and a Mailchimp newsletter from Kompozy's queue, with Autopilot and a per-post review pipeline. Hyprnote captures the thinking privately; Kompozy turns the parts you choose into published work.
Hyprnote is an open-source, privacy-first AI notepad for meetings on macOS, launched via Y Combinator (S25) with a Launch HN on August 11, 2025. It captures both your microphone and your Mac's system audio — no meeting bot required — then transcribes and summarizes the conversation on-device using a local Whisper model and HyprLLM, a small model fine-tuned from Qwen3 1.7B. The open-source app is now continued under the name Anarlog.
By default, yes. Transcription and summarization run locally on your Mac, so audio and meeting content don't leave the device and there is no bot in the call. You can optionally point it at your own cloud LLM API key for stronger summaries, but that's an explicit choice — out of the box it stays on-device.
The app is open source and free to run with its local models. A paid cloud tier adds hosted models and team features for people who want them. Because pricing and the product name have changed since launch (it now continues as Anarlog), confirm the current tiers on the official site before relying on a specific number.
No. Hyprnote records, transcribes, and summarizes meetings — it writes no posts, cuts no clips, designs no carousels, and publishes nowhere. To turn a meeting into captioned video, carousels, a blog, a newsletter, and scheduled posts across platforms, you use a content engine like Kompozy.
Hyprnote is the private place a talk gets captured; Kompozy is where the shareable parts become published content. Record the meeting or webinar in Hyprnote, copy out the parts you want public, and paste them into Kompozy — which rewrites them in your brand voice and generates a blog, newsletter, carousels, quote cards, text posts, and avatar video, then schedules and publishes across eight social platforms plus blog and email.
