Beat the blank page — which AI gives you 50 ideas worth keeping, not 50 ideas worth ignoring.
One prompt, four answers side by side: ChatGPT, Claude, Gemini and Grok in Compare Mode
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.
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.

Ranking reviewed October 2026 against each provider's current flagship models: OpenAI GPT-6.1 Sol and GPT-6 Astra, Anthropic Claude Opus 5.5 and Sonnet 5.5, Google Gemini 4 Argon and xAI Grok 4.7. Scores are our editorial judgement of typical results for brainstorming, not a published benchmark.
How wide is the spread from safe to risky?
Will it tell you which idea it likes?
Are the ideas tangible, or vague?
How many of the 30 ideas would you not have had?
Three rules: ask for the full range, ask for the strongest 3, run it in two models in MultipleChat for diversity.
No. AI is the first-pass generator. The taste of choosing what's actually good is still yours.
ChatGPT for volume, Claude for the ones with character.
Treat them as recommendations, not verdicts. Run the same prompt twice and see which ideas come up both times — those are the real winners.
Compare Mode sends one prompt to ChatGPT, Claude, Gemini and Grok and shows the answers in parallel columns, so you can check this ranking on your own problem. The $20/month Pro plan includes all four, plus Perplexity.
