Already Grug?
Here's the deal — three simple moves
1. Write stuff down.
Type or talk. Plain text, no formatting, no organizing, no fuss.
2. Grug connects the dots.
Names, dates, companies auto-link; phone numbers, emails, and other attributes get extracted and filed where they belong.
3. Get answers.
Ask things like "Who do I know in tech that surfs?" or "What's on my training schedule for Monday?" If it's in your notes, Grug tells you.

For the nerds in the room
Old-school web tech meets cutting-edge AI.
Because sometimes boring is beautiful.
Built Like It's 2009 (In a Good Way)
- • Django + MySQL (battle-tested for decades)
- • Hosted on Google Cloud Run
- • Server-rendered HTML with HTMX sprinkles
- • Optimized for cold starts
- • Works on slow connections
- • Multi-page app where back button always works
AI Without the Hype
- • Do useful things is the number one goal
- • Multiple LLMs (OpenAI, Anthropic, Google)
- • Vector embeddings for semantic search
- • Whisper 3 for accurate voice → text
- • Named entity recognition and attribute extraction
- • AI as assistant, not author
Philosophy: We take inspiration from Hacker News, Craigslist, and McMaster-Carr. Use proven tech, sprinkle in modern AI where it actually helps. Skip the heavy JavaScript frameworks. Build something fast, functional, and built to last.
A canoe company making software?
Grug Notes is a product from Kamanu Composites. Yes, we make canoes. We design them, build them from scratch, and sell them directly to customers. We do everything in-house to a fault — including building our own software since 2008. In 2020, we made 900,000 face shields and stayed organized with Roam Research. We learned a lot about scale, note-taking, and life.
After that, we knew what we wanted: the organization without the overhead. The linking without the learning curve. Notes that work when you're on the shop floor. So, in October 2022, we put a text box on a website, and Grug Notes was born. We march forward, always keeping simplicity at our core and our roots in manufacturing in our hearts.
Seven bucks a month.
Caveman simple.
Use Grug free for 30 days—no credit card, no hoops.
If it's worth it, pay $7 and keep rolling.
That's it. That's the pitch.
