AI for Ideation: How to Use AI to Brainstorm and Generate Ideas

When we first published this guide, using AI to generate ideas meant typing a question into a brand-new chatbot and marveling that it answered. That phase is over. The question teams ask us now in workshops is more practical: how do you use AI to generate ideas that are genuinely better than what your group produces alone, and how do you run that process well with real people in a real session?

This updated guide is our full answer. It covers why AI is unusually well suited to ideation, how to frame a challenge before you prompt anything, how to upgrade the classic brainstorming techniques we have taught for years with AI, and how to facilitate all of it with a group.

Why AI Is Genuinely Good at Idea Generation (and Where It Is Not)

Idea generation rewards volume, variety, and unexpected combinations. Decades of research on group brainstorming show that people struggle with all three: we fixate on the first ideas we hear, our output drops quickly, and our range is limited to the experiences of whoever is in the room. AI has the opposite profile. It produces enormous volume instantly, draws on knowledge from every industry at once, and is never embarrassed by a strange idea.

The weakness matters just as much. AI cannot tell you which idea fits your users, your culture, or your constraints. It generates; it does not judge. Every method in this guide is built on that division of labor: AI supplies volume and range, humans supply context and judgment. Keep that split and AI makes your ideation dramatically stronger. Lose it and you get a long list of plausible-sounding ideas nobody believes in.

Start with the Challenge, Not the Tool

The most common mistake we see is prompting AI before the problem is framed. Idea quality follows question quality. In our own work we use the Challenge, Ideas, Action framework, where real effort goes into defining and framing the challenge before any idea generation begins. You can read the full approach in our guide to the Challenge, Ideas, and Action design thinking framework.

Practically, this means turning your problem into a “How might we” question and testing a few framings before you ideate. AI helps here too: paste in your rough problem statement and ask for ten alternative “How might we” framings at different levels of scope. Choosing the right framing is a human judgment call, and it is often the most valuable five minutes of the whole session.

Classic Brainstorming Techniques, Upgraded with AI

The techniques facilitators have used for decades work better with AI, because AI removes their traditional bottlenecks: running out of ideas, skipping uncomfortable steps, and uneven participation. Here is how we combine them.

Reverse brainstorming with AI

Ask how to make the problem worse, generate freely, then flip the answers into solutions. AI is remarkably good at this because it applies the inversion without hesitation. Prompt it to generate twenty ways to guarantee the problem gets worse, then work with your team to reverse the most revealing ones. Our reverse brainstorming training guide covers the base technique and templates.

SCAMPER with AI

SCAMPER walks you through Substitute, Combine, Adapt, Modify, Put to another use, Eliminate, and Reverse. Run by hand, people favor the prompts they find easy and rush past the rest. Ask AI to run the complete framework against your product or process and you get disciplined coverage of every angle, ready for your team to react to. Start with our SCAMPER templates if the technique is new to your group.

Six Thinking Hats with AI

Edward de Bono’s technique assigns thinking modes: facts, feelings, caution, optimism, creativity, and process. AI can wear any hat on demand, which makes it a tireless sparring partner. Have it argue the Black Hat case against your favorite idea, then the Yellow Hat case for the idea your team almost discarded. The full method is in our Six Thinking Hats training guide, which remains one of the most-read technique posts on this site.

The 100 Ideas exercise with AI

Quantity-first techniques work because obvious ideas exhaust themselves and the interesting material appears late in the list. The 100 ideas exercise traditionally takes a full session of group energy. With AI, a useful variation: your team generates the first 30 by hand, AI generates the next 70 with instructions to get progressively less conventional, and the group mines the full list together. Humans first is the important part, for reasons covered in the facilitation section below.

Round robin and brainwriting with AI

Techniques like round robin brainstorming exist to fix participation problems, making sure quiet voices contribute and loud voices don’t anchor the group. Add AI as one more silent participant in the rotation: each person builds on the previous idea, and every third round the AI extends the chain in an unexpected direction. It keeps momentum when a chain stalls.

One more foundational note: the original rules for brainstorming, defer judgment and go for quantity chief among them, apply to AI-assisted sessions unchanged. If anything they matter more, because the temptation to start judging is stronger when ideas arrive this fast.

Prompts That Produce Better Ideas

Three prompt habits separate productive AI ideation from generic output. First, load context: paste in your challenge framing, your audience, your constraints, and any real user insight you have before asking for a single idea. Second, direct the distribution: “make the last ten unconventional, drawing from industries far from ours” reliably improves the tail of the list. Third, iterate rather than accept: push back, combine, ask for variations on the two most promising directions. Prompting is a skill of its own, and our guide to getting better AI prompt results covers the strategies in depth, with current model-specific tips in our ChatGPT-5 prompting guide.

AI on the Whiteboard: Group Ideation Tools

For team sessions, the AI built into visual collaboration platforms often beats a chat window because everyone works on a shared canvas. Miro’s AI can generate sticky notes, cluster the group’s ideas into themes, and expand a promising cluster on command; see our overview of Miro AI and our walkthrough of mind mapping with Miro AI. Mural offers similar capabilities, covered in our Mural AI guide. If you are setting up a virtual session from scratch, our collection of 40+ brainstorming templates pairs well with any of these tools.

How to Facilitate an AI Ideation Session

A sequence we use with client groups, refined over many sessions:

1. Frame the challenge together. Agree on the “How might we” question before anyone opens a laptop.
2. Humans generate first. Individual silent ideation, then sharing. If AI goes first, it anchors the group and people unconsciously produce variations of the AI’s ideas instead of their own.
3. Run an AI round. Use one of the upgraded techniques above, projected or on the shared whiteboard so the group experiences it together.
4. Mix and select blind. Combine human and AI ideas without labels and have the team select the strongest. Groups are regularly surprised by which ideas survive, and the debrief conversation about why is where the learning happens.
5. Develop, don’t just collect. Take the top two or three ideas into development: sketch them, pressure-test them with Six Thinking Hats, or prototype them. Our guide to idea generation methods in design thinking covers where ideation sits in the larger process.

This sequence also quietly teaches teams the right mental model for AI at work: people bring context and judgment, AI brings volume and range, and the output belongs to the humans who selected and developed it.

Putting It into Practice

AI ideation rewards practice with real challenges, and the fastest way for a team to build the capability is to do it together with a skilled facilitator on a problem that matters. We design and facilitate innovation and brainstorming workshops that put these methods to work on your organization’s actual challenges, with AI woven into the process where it genuinely helps.
