A 90-second walkthrough from rough draft to optimized prompt.
Everything you need to write prompts that perform
Real techniques, real diffs — no guesswork.
One-Tap Rewrite
Paste any rough prompt and Refine restructures it into a clean, role-framed instruction with context, constraints and an explicit output format.
Improvement Score
Every rewrite ships with a 0–99 quality score that shows exactly how many upgrades were applied and how much stronger your prompt got.
Six Proven Techniques
Role, context, constraints, format, few-shot and chain-of-thought — tap any tag to see what changed and why it lifts model output.
Technique Library
Browse every building block with side-by-side before/after examples, then save optimized versions and revisit the full breakdown any time.
The AI upgrade that changes everything
Today Refine uses a deterministic technique engine. Tomorrow — a model that learns your voice and tunes every prompt to your exact LLM.
Model-Aware Tuning
Refine detects whether you are targeting GPT, Claude or Gemini and rewrites with each model's quirks and best practices in mind.
PlannedAuto A/B Optimization
Generate prompt variants, score them against your goal, and surface the single highest-performing version automatically.
PlannedMulti-Step Chains
Turn one objective into a chained sequence of prompts, each handing structured output to the next without manual stitching.
PlannedLive Voice Matching
Paste a few of your own messages and Refine learns your tone, so every optimized prompt still sounds unmistakably like you.
