Can your notes app even do anything?
Grug can. Grug organizes, remembers, answers. Edits, reminds, plans. Talks. Emails. Calculates.
Bullshit. Explain.
(hint: ChatGPT and Apple Notes had a baby. Notion was not invited.)
A notebook that listens
Record multi-speaker meeting notes. Ramble through a long solo brainstorm. Capture a two-sentence memory before it disappears.
Everything gets organized instantly.
Edit by voice too — say what's wrong, Grug fixes it.
A wiki for your life
Wikipedia was a great way to organize information. Grug Notes uses the same idea, just simpler, just automatic, and just for you.
Mention someone and they get their own page — phone numbers, emails, addresses, every conversation in one place. Same for companies and dates.
Software that's alive
Grug can operate Grug Notes. Email Grug, message Grug on Telegram — Grug help.
Schedule Grug to check in on your goals, send you a daily brief, or remind you what's coming up. Ask Grug to read or add to your notes as needed.
Pro tip: Start with daily notes. Just dump everything there. The system figures out where it belongs. No folders, no categories, no decisions.

All included — chat with your notes as context, get multiple perspectives, and plan anything.

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. 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.
