10 Best Brainstorming Tools in 2026 (Tested & Scored on 6 Criteria)

What are the best brainstorming tools in 2026?

The best brainstorming tool depends on how you work. Miro (best for team workshops) leads with the templates, sticky notes, and real-time collaboration group sessions need. MindMap AI (best for AI brainstorming that turns ideas into structure) is strongest when you want to take raw ideas and organize them into an editable map. Stormboard is best for structured, data-driven sessions, Mural for facilitated workshops and voting, and FigJam for design teams. The right pick comes down to team collaboration, idea generation, or turning ideas into a plan.

Quick answer

Quick comparison

These five tools cover the decisions most people are making: brainstorming with a team, turning ideas into structure with AI, running a data-driven session, facilitating a workshop, or ideating inside a design workflow.

Read this table as the standard axis (overall capability). The deciding axis for most readers is how you brainstorm, with a team, with AI, or to produce a plan, which is what the reviews below focus on.

How I tested and scored these brainstorming tools

I ran every tool through the same session and judged the outcome, not the feature list.

• Same brief – "Generate directions for a product launch campaign," run first solo and then with a small group, to see how each tool handled both.
• Idea generation – whether the tool only gives you a surface for ideas, or actively helps generate, expand, and diverge.
• Collaboration – live multi-user co-editing with two to ten people.
• Frameworks and facilitation – templates, voting, timers, and structured workshop flows.
• Turning ideas into structure – how easily a messy set of ideas became themes, a map, or a plan you could act on.
• Free-plan value – whether the free tier supports a real session.

The main benchmark, time to first organized output. Tools that build structure with AI reached an organized first draft in roughly 40 to 60 seconds from a prompt or file; blank-canvas whiteboards needed a few minutes of manual setup before a group could work. (Time-to-first-value is a standard usability measure; see Nielsen Norman Group on usability metrics.)

The scoring rubric. Each tool was scored 1 to 5 on six criteria, then weighted to a score out of 10. I weight idea generation and real-time collaboration most heavily, because brainstorming is about producing ideas together; every tool, ours included, was scored on the same rubric.

MindMap AI is one of the tools tested here. It is the publisher of this guide, and it scores a 2 out of 5 on collaboration, stated openly. Every tool, ours included, was scored on the same criteria, and the reviews call out where competitors do it better.

All pricing was verified in June 2026. Prices are in USD and the billing basis is noted. Tool pricing changes often, so check each vendor's current page before relying on a number.

Quick comparison table: 10 best brainstorming tools

Two things to notice. First, the strongest team tools (Miro, Mural, FigJam, Stormboard) are built for live group sessions, while the strongest idea help comes from AI tools (ChatGPT for raw volume, MindMap AI for turning ideas into structure). Few tools do both. Second, the AI is uneven: many tools generate a first draft and stop, while only a couple keep working with you to expand and organize ideas.

Detailed reviews: 10 best brainstorming tools in 2026

1. Miro: best for team brainstorming and workshops

Miro is the default whiteboard for group brainstorming, and with good reason. It pairs a huge template library with sticky notes, clustering, and reliable real-time sync, so a team can run a structured session without much setup.

Strengths

• Large template library with ready-to-run flows like How Might We and Crazy 8s
• Sticky notes with color-coding and one-click clustering for large sessions
• Built-in facilitation: timer, dot-voting, and presentation mode
• Sidekick AI can generate ideas from a prompt, cluster sticky notes, and summarize a board

Limitations

• The AI reads only the current board, and asking it to update a map can spin up a separate diagram
• Less intuitive for first-time participants than simpler tools
• Per-seat pricing adds up for large teams, and the free plan is capped at 3 boards

Pricing: Free plan with 3 editable boards and 10 AI credits per month shared across the team. Starter is $8 per member per month, and Business is $20 per member per month. Enterprise is custom.

Verdict: Best for remote and hybrid teams that run structured group brainstorming regularly.

2. MindMap AI: best for AI brainstorming that turns ideas into structure

MindMap AI is the strongest pick when the goal is to take a brainstorm and turn it into a clear, editable structure. Full disclosure: we build MindMap AI, so I held it to the same rubric as every other tool and scored it honestly, including a 2 out of 5 on collaboration. Live group sessions are not its strength. It generates a map from a prompt or a file, and a continuous AI copilot keeps working on the same map: expand a branch, summarize, focus, or restructure.

Strengths

• Generate a map from a prompt, PDF, document, image, audio, video, or webpage
• Continuous AI copilot with Expand, Summarize, Focus Topic, and Relationships
• Node widgets for converging: 7-level priorities, task progress, flags, stars, people, and dates
• Unlimited free manual mapping, plus 50 AI credits a month
• Turns a messy set of ideas into a clean hierarchy you can act on

Limitations

• Team workspaces and sharing, but no mature real-time co-editing, so it is weaker for live group sessions than Miro or Mural
• Built around mind maps, not a free-form whiteboard or sticky-note canvas
• Long files use more AI credits

Pricing: Unlimited manual mapping free forever, with 50 AI credits per month on Free. Basic is $9.99 per month (or $4.99 per month billed annually). Pro is $14.99 per month (or $7.99 per month billed annually). Lifetime plans are $157, $237, and $397. Verified students get 70% off.

MindMap AI holds a 4.6 out of 5 average across 33 reviews on G2. As one verified user in management consulting put it, a complex PDF becomes a structured mind map fast, cutting their conceptual organization time by around 70%.

Verdict: Best for students, researchers, and solo creators who want AI to organize a brainstorm into a structured map. For live team workshops, choose Miro instead, real-time collaboration is where MindMap AI is weakest today.

3. Stormboard: best for structured, data-driven sessions

Stormboard treats every sticky note as a data point. It is built for structured ideation where you need templates, voting, and a shareable report at the end.

Strengths

• 250+ configurable templates for design thinking and large ideation sessions
• StormAI generates structured templates with contextual sticky notes and auto-categorizes ideas
• Voting and prioritization to decide what came out of a session
• Storm Reports export to PowerPoint, PDF, Word, and Excel

Limitations

• Less visually polished than Miro or FigJam
• The data and reporting features add a learning curve
• More structured and enterprise-leaning than a blank whiteboard

Pricing: Free Personal plan. Paid plans start at about $5 per user per month, with Business and Enterprise tiers above that.

Verdict: Best for facilitators and innovation teams who need structured sessions with voting and shareable reports.

4. Mural: best for facilitated workshops and voting

Mural is the facilitation specialist. It is built for teams that run brainstorming as a structured workshop, with the strongest facilitation toolkit here.

Strengths

• Best-in-class facilitation: timed rounds, anonymous voting, and guided workshop flows (including LUMA methods)
• Anonymous voting changes how honestly groups evaluate ideas
• Mural AI summarizes discussions and clusters related ideas into themes
• Strong enterprise controls for security and compliance

Limitations

• Busier interface than Miro, with more onboarding for new participants
• AI is paywalled to Team+ and runs as node-specific actions rather than open generation
• The free plan is 3 murals with no AI

Pricing: Free plan with 3 murals. Team+ is $12 per user per month (about $119.88 per year). Higher tiers and Enterprise are available.

Verdict: Best for facilitators and enterprise teams running high-stakes, structured workshops.

5. FigJam: best for design teams

FigJam is the brainstorming layer for teams already in Figma. Ideas generated in a FigJam session move into Figma design files without a context switch, which is its main advantage.

Strengths

• Sits inside the Figma workflow, so ideas flow into design work
• Large community library of brainstorming and design-thinking templates
• Strong real-time collaboration with cursors, audio, and reactions
• FigJam AI sorts and clusters sticky notes and summarizes them into takeaways

Limitations

• Most valuable only if your team already uses Figma
• AI is more about organizing stickies than open idea generation
• Less suited to non-design brainstorming

Pricing: Free plan with unlimited personal whiteboards and 3 shared FigJam files. FigJam Professional is about $3 per editor per month (billed annually) or $5 monthly. (Figma's design Professional plan, $16 per user per month, is priced separately.)

Verdict: Best for product and design teams who want brainstorming next to their design files.

6. Boardmix: best for AI-powered whiteboard brainstorming

Boardmix is an AI whiteboard that goes beyond mind maps into flowcharts, data visualizations, AI presentations, and analysis reports. You can start from a prompt, upload a file, or build on a blank canvas.

Strengths

• One canvas for mind maps, flowcharts, data visualizations, and AI presentations
• Generates maps from prompts and file uploads, with a Thinking Mode
• Real-time team collaboration and iFrame embed
• Lifetime plans available as a one-time purchase

Limitations

• Asking the AI for changes creates a new map each time, with no continuous copilot
• No AI expand, summarize, focus, relationships, or multi-language generation
• The free plan is limited to 3 boards (150 objects each) and 500 total AI credits

Pricing: Free plan with 3 boards. Starter is $12 per month, or about $5 per month billed annually ($60 per year), with a Business tier at $96 per year and lifetime options.

Verdict: Best for teams that want an AI whiteboard spanning maps, diagrams, and presentations in one place.

7. Whimsical: best for quick visual brainstorming

Whimsical is a fast, clean workspace for mind maps, flowcharts, and sticky-note boards. Its AI turns a text prompt into a structured mind map in seconds, which makes it a quick way to get a visual starting point.

Strengths

• Fast, keyboard-driven interface with polished output
• AI generates a mind map from a prompt in seconds
• Combines mind maps, flowcharts, wireframes, and sticky notes
• Strong real-time collaboration

Limitations

• Each AI prompt creates a new map rather than refining the existing one
• Fewer templates and no timers, voting, or presenter facilitation
• Free plan is capped at 3 boards with 100 lifetime AI actions, and free exports are watermarked

Pricing: Free plan with 3 boards. Pro is $12 per editor per month, or $120 per year (about $10 per month).

Verdict: Best for teams that want quick, clean visual brainstorming without a heavy whiteboard.

8. ChatGPT: best AI partner for fast raw ideas

ChatGPT is not a visual canvas, but for generating raw ideas it is the fastest partner available. You can throw a half-formed idea at it, get ten directions back, push for a contrarian take, or brainstorm from a specific perspective.

Strengths

• Generates a high volume of ideas and angles in seconds
• Holds context across a conversation, so you can build on ideas iteratively
• Can take on perspectives (skeptical customer, competitor) for sharper ideation
• Canvas gives a side-by-side space to refine text, and it accepts images and files

Limitations

• No visual canvas, sticky notes, or spatial organization for a brainstorm
• No live multi-user co-editing during a session
• No built-in templates, voting, or facilitation

Pricing: Free plan available. ChatGPT Go is $8 per month, Plus is $20 per month, Pro is $200 per month, and ChatGPT Business is $25 per user per month ($20 billed annually).

Verdict: Best for solo, early-stage divergent thinking where speed and volume matter most, usually a first step before moving ideas into a visual tool.

9. Coggle: best for simple collaborative mapping

Coggle is a browser-based mind mapping tool that handles collaborative brainstorming at a price no other tool matches. It is fast, intuitive, and easy for a group to pick up.

Strengths

• Among the easiest tools to learn, with nothing to set up
• Real-time collaborative mind mapping with live cursors and presence
• Generous free plan and a low-cost paid tier
• Clean export options (PDF, PNG, Text, Visio)

Limitations

• No AI features at all
• Web only, with limited styling and few frameworks
• Best for straightforward mapping, not structured workshops

Pricing: Free plan with 3 private diagrams and unlimited public diagrams. Awesome is $5 per month, and Organization is $8 per member per month.

Verdict: Best for small teams that want simple, low-cost collaborative mind mapping.

10. Milanote: best for visual and creative ideation

Milanote is a visual workspace for creative brainstorming: mood boards, inspiration boards, and early creative briefs. It is more visually expressive than a standard whiteboard, which suits creative work.

Strengths

• Excellent for mood boards and visual creative ideation
• More visually expressive canvas than most whiteboards
• AI can generate text ideas and image references
• Clean, calm interface for solo creative work

Limitations

• Leans asynchronous, so it is weaker for live group sessions
• Light on structured frameworks, voting, and facilitation
• Less suited to process-heavy team brainstorming

Pricing: Free plan with 100 cards (notes, images, and links combined) plus 10 file uploads. Pro is $9.99 per month (billed annually), with team plans above that.

Verdict: Best for individual creatives and small design teams doing visual ideation.

What I excluded and why

I left out tools where brainstorming is incidental rather than the core job. Grouped by category:

• Document and workspace tools such as Notion and Google Docs. They are excellent for writing up and organizing ideas, but they generate and store text rather than offering the visual, spatial canvas a brainstorm needs. If your sessions live in documents, they are fine, but they are not brainstorming-first tools.
• Communication and meeting tools such as Zoom, Slack, and Microsoft Teams. They are useful for talking ideas through during a session, but they are conversation tools, not spaces for generating and organizing ideas.
• Note-taking and dictation tools such as OneNote, Evernote, and Wispr Flow. They capture ideas well but do not help you generate or visually organize them.

If your real need is turning source material into a structured map, start with MindMap AI or read my guides to the best mind map software and the best AI mind map generators.

Honorable mentions

Two tools that nearly made the list, each for a specific person:

• Lucidspark – the pick for teams already in the Lucid suite who want a sticky-note brainstorming canvas alongside Lucidchart diagrams.
• Ayoa – the choice for teams that want organic, colorful mind maps combined with task boards and whiteboards in one workspace.

Conclusion

The best brainstorming tool comes down to how you work. If you brainstorm with a team, Miro is the most reliable, with Mural close behind for facilitated workshops, Stormboard for data-driven sessions, and FigJam for design teams. If you want raw ideas fast on your own, ChatGPT is the quickest partner.

The step most tools skip is turning a messy brainstorm into something you can act on. If that is where you get stuck, MindMap AI is the best pick here, because it takes ideas from a prompt or a file and organizes them into a clear, editable map you can keep building with AI. For live group sessions, start with Miro instead.
