Best AI for Brainstorming

Beat the blank page — which AI gives you 50 ideas worth keeping, not 50 ideas worth ignoring.

Try All Four in MultipleChat

No credit card · run the same prompt across all 4 models in one window

Brainstorming is the use case where AI's main weakness — bias toward safe, average outputs — bites hardest. All four can generate ideas; the gap is between models that produce 50 generic ones and models that include 5 surprising ones.

The ranking weights surprise, range, and willingness to commit to a strong idea over safety.

Best for range

Claude wins for brainstorming

Claude produces the broadest range of ideas — from the safe predictable ones to the genuinely unexpected. It's also the most likely to commit to which idea it actually thinks is strongest, not just list options. Grok is the close runner-up for any task where 'edgy' is the point.

Try this prompt

Brainstorm 30 ideas for [problem]. Cover the full range from safe and predictable to surprising and risky. Then pick the 3 you actually think are strongest and tell me why.

All four models, ranked for brainstorming

1

Claude (Anthropic) recommended

Score 9.3/10

ChatGPT (OpenAI)

Score 8.8/10

Strength

Fastest brainstorming; great at structured frameworks (SCAMPER, etc.).

Volume brainstorms, naming, listicle generation.

Idea generation grounded in market reality.

What we actually measure for brainstorming

Range

How wide is the spread from safe to risky?

Willingness to commit

Will it tell you which idea it likes?

Specificity

Are the ideas tangible, or vague?

Surprise rate

How many of the 30 ideas would you not have had?

FAQ

How do I get better brainstorms?

Three rules: ask for the full range, ask for the strongest 3, run it in two models in MultipleChat for diversity.

Will AI replace my creative team?

No. AI is the first-pass generator. The taste of choosing what's actually good is still yours.

Best AI for naming?

ChatGPT for volume, Claude for the ones with character.

Can I trust the ‘best 3' picks?

Treat them as recommendations, not verdicts. Run the same prompt twice and see which ideas come up both times — those are the real winners.

Don't pick — use all four

MultipleChat lets you run the same prompt across ChatGPT, Claude, Gemini and Grok side-by-side. Verify the ranking on your actual work, not someone else's benchmark.
