About Limnu

Limnu is a commercial online whiteboard built for quickly sketching ideas with other people. Its focus is on drawing together rather than on heavy structure, which suits brainstorming, video calls and online meetings.

The vendor highlights an expansive canvas with no edge boundaries and a simple, marker-like drawing experience. Typical uses it lists include business analysts mapping process flows, distributed engineering teams drawing state diagrams, product teams prioritizing features, freelance designers reviewing storyboards and tutors working through math problems with students. Visitors can try a board without signing up.

Limnu also offers a whiteboard API, a plan for educators and professional services, along with free sign-up and paid plans on its pricing page.
