Use tool ↗About Stormz
Stormz is a workshop-facilitation platform built by Stormz SASU, a French company, for running brainstorming and decision-making sessions online. Facilitators plan a session, run it with participants moving and voting on idea cards, then export the results; AI boosters can generate starter ideas, reframe them as How-Might-We questions, illustrate them, or cluster and label a large pile of cards automatically. A free plan caps sessions at two participants; paid plans start at $10 a month for ten participants and scale up to enterprise contracts.

Pros & cons of Stormz
A capable option for teams that run structured brainstorming workshops regularly and want the AI boosters as a time-saver during ideation, not a replacement for facilitation. The free plan is really just a two-person demo; a team actually running workshops will land in the $10-$50/month range fairly quickly.
Pros
- AI boosters cover idea generation, reframing, illustration, and clustering in one flow
- built-in voting and multicriteria evaluation for narrowing down ideas
- exports results to Excel for follow-up
- free plans available for schools, nonprofits, and early-stage startups
Cons
- free plan is capped at two participants, too small for a real workshop
- pricing jumps quickly from $50 to $200/month as participant counts grow
- no platform details are given — unclear if there's a downloadable app or web-only
Best for
- facilitators running recurring brainstorming or ideation workshops
- teams that want AI-generated starter ideas and automatic clustering of a large card pile
- distributed teams needing a shared voting and evaluation tool
Not for
- a single person brainstorming alone
- teams wanting a general whiteboard rather than a structured workshop flow
