AI tools
RainbowAI
Small, sharp tools for getting work out of language models — without the ceremony.
The shape of it.
RainbowAI is a small set of utilities we use every day at the studio, packaged up for everyone else. Prompt scratchpads, model-side-by-side comparisons, and the kind of quiet quality-of-life touches that make working with LLMs feel less like a tax return.
No magic. No agents pretending to be people. Just sharp little tools that do one thing well, get out of the way, and don’t pretend AI is a personality.
What’s in it.
-
Side-by-side runs
Same prompt, multiple models, one screen. Diff the answers without copy-pasting between tabs.
-
Prompt scratchpad
Save, version, and share prompts the way you save snippets in your editor.
-
Bring your own keys
No middleman. We don’t see your tokens, your prompts, or your usage.
