What is the Dice Roller?

A free tool that runs the same prompt against an AI model five times, then shows which brands and answers the model always returns vs. only sometimes returns. It measures AI response stability.

Why run the same prompt five times?

AI models are non-deterministic. Asking ChatGPT "best CRM for startups" five times can return five different lists. Brands that show up every time are AI-stable. Brands that appear only sometimes are phrase-dependent. Stability is the leading indicator of recommendation share.

Which AI models can I test?

ChatGPT (multiple OpenAI models), Gemini, Grok, and Perplexity. Research users can also run multi-model experiments to compare cross-model agreement on the same prompt.

Yes. The browser version uses your own API key, so you control the cost. We also publish 100+ result archives for free reading at /dice-roller/results.

What do the stability categories mean?

Stable: the brand appears in all five runs. Variable: the brand appears in some but not all. Missing: the brand never appears. The result page color-codes every brand by category.

Can I publish my results?

Yes. Click "Publish" on any result to get a permanent link at /dice-roller/results/{slug}. Published results are indexed by search engines and discoverable by AI assistants.

How the dice roll works

AI answers change between runs. The dice roll measures how much, the same way the stability roll works inside the Rankfor platform.

Type a buying question your customers ask AI, for example "best CRM for small businesses". Add your brand to track it.

We roll it several times

The same prompt runs up to 5 times against one AI model on our servers. No API key, nothing to install.
