Prompt Optimizer
Better prompts for ChatGPT, Claude & Gemini
Vague prompts get vague answers. SamaBrains turns a rough idea into a structured Master Prompt you can paste or inject into your AI of choice.
The solution
Most people type a half-sentence into ChatGPT and hope for the best. The model guesses tone, format, and constraints — and often misses.
SamaBrains turns a rough idea into a structured Master Prompt with clear goals, constraints, and output expectations. You can score it, fix weak spots, refine it, or split big jobs into a Prompt Chain.
- Stop rewriting the same vague request — get a reusable prompt structure.
- Match the target AI and category (writing, coding, marketing, and more).
- Work on live web, in the extension popup, or with the side button inside ChatGPT, Claude, and Gemini.
Who can use it
Anyone who prompts AI in Chrome (or a Chromium browser). Free tier needs a one-time email verify.

Students & educators
Clearer study prompts and lesson-style outputs with learner level and checks.
