Local AI Optimisation

Any Ollama model runs on your machine. Choose from Gemma, Llama, Mistral, Phi and more. Your raw prompt is refined entirely on-device — never sent anywhere.

🔀

Any AI Provider

Send to OpenAI, Anthropic, Google Gemini, Groq, Mistral, xAI Grok, or OpenRouter — all in one interface.

🎭

Tone Injection

Confident, technical, concise, creative, mentor — inject a response style into every prompt automatically.

🔍

Full Prompt Visibility

See exactly what was sent: original prompt, optimised version, and final assembled prompt with tone — side by side.

🖥️

macOS, Windows & Linux

Runs as a local web app in your browser. One setup script handles everything — Ollama, models, dependencies.

🔑

Your Keys, Your Control

API keys stored only in a local JSON file on your machine. We never see them, never store them.

How it works
Four steps from idea to answer
1

Write naturally

Type your prompt as you normally would — no special syntax or formatting needed.

2

Ollama optimises

Your chosen local model rewrites the prompt to be clearer, more specific, and better structured.

3

Add a tone

Optionally inject a response style — confident, technical, concise, mentor, or seven others.

4

Get a better answer

The refined prompt is sent to your chosen AI. View all three versions side by side.
