AI Brainstorming Tool — Free Online Brainstorm Generator

How it works

Describe your topic or challenge

Enter a prompt, question, or goal. The more context you give, the more focused the ideas — but broad prompts work too for open exploration.

AI generates ideas

MyMap's AI brainstorms across multiple angles and places ideas on the canvas as cards — grouped by theme and ready to build on.

Explore and expand

Ask AI to go deeper on any idea, generate variations, or combine themes. Move ideas around, add your own, and shape the session visually.

What is Brainstorming?

Brainstorming is a creative ideation technique introduced by advertising executive Alex Osborn in the 1940s. The goal is to generate a large volume of ideas as fast as possible by suspending judgment — quantity over quality, divergence over convergence. Once ideas are out, you evaluate and filter.

The format works for any challenge: naming a product, solving a technical problem, planning a marketing campaign, or generating content ideas. The key principle is that no idea is too wild early in the process.

Why brainstorming works

Breaks fixation — the pressure to generate many ideas forces you past the obvious first answers

Encourages lateral thinking — diverse ideas spark unexpected connections

Surfaces hidden assumptions — articulating many options reveals what constraints you've been taking for granted

Separates generation from evaluation — avoiding premature filtering leads to more creative outputs

Visual brainstorming — where ideas appear as cards on a canvas rather than in a list — makes it easier to group, connect, and build on ideas spatially.

MyMap's AI generates a broad spread of ideas across multiple angles from a single prompt, organized visually on a canvas so you can explore, cluster, and develop the most promising directions instantly.

Common questions

Is the brainstorming tool free?

Yes — brainstorm for free without signing up. Free accounts include a generous number of AI messages per month. Upgrade to Pro for unlimited sessions.

How is this different from a mind map maker?

Mind maps branch from a single central topic in a hierarchical structure. Brainstorming is more open — ideas spread freely across the canvas without a strict hierarchy. Use brainstorming to generate raw ideas, then a mind map to organize them.

Can I brainstorm with a team?

Yes. Share a live link and collaborators can view in real time. Pro users can invite others to edit the canvas together, making it a collaborative brainstorming session.
