PersonaSync
Train your AI once. Use it everywhere.
PersonaSync turns any AI assistant into a teammate who already knows you. Your persona — your communication style, your priorities, what to skip, what to focus on — gets translated into a system prompt tuned for each AI's quirks, so ChatGPT, Claude, Gemini, and Grok all behave consistently every time you use them.
The adapters stay current as providers evolve — when they change how they read system prompts, the tuning updates with them, so you don't have to re-learn each model's quirks.
Today: generate your prompt and paste it yourself.
Next: auto-injection, persona libraries, energy-aware responses, decision memory — see the full roadmap below.
Built and building
PersonaSync is a framework with a roadmap. Here's what's live, what's in progress, and what's planned.
Provider-tuned prompt generation, always current
Generate adapter-applied system prompts for every supported AI, plus a generic adapter for the rest. Each provider gets its own tuning so your persona lands the same way across every model. Adapters are pulled fresh from the framework on every generation — when a provider changes how it reads system prompts, the tuning updates with it, and you stay optimized without doing the work.
One-click auto-injection with model-tier detection
A Chrome extension that detects which AI you're using and which specific model tier — Claude Opus vs Sonnet, Gemini Pro vs Fast, etc. — and injects the right adapter directly into the settings page. No copy-paste, no manual tuning per model variant. Launching with every supported AI web interface.
Persona auto-generation from personality profiles
Skip the blank-page problem. Generate a starter persona from standardized profiles — Myers-Briggs type, Hogwarts House, love languages, attachment style, and more. Mix and match the frameworks that map to how you actually think.
Persona library + custom agents
Save and switch between multiple personas for different workflows — work, research, creative, coding. Layer task-specific agent directives on top of any persona for specialized AI assistants.
Shared decision memory
Stop re-training your AI every conversation. PersonaSync silently remembers the last few key decisions you've made with each AI — recurring projects, preferred formats, ongoing constraints — and prepends that context so you never have to repeat yourself.
Energy-aware responses
Some days you want sparring, some days you need short and calm. An energy slider tells your AI to match your day — verbose deep-dives on hyperfocus days, low-friction directness on bad pain days. Built especially for creators, veterans, and neurodivergent users who need consistent, low-friction collaboration.
Update notifications & one-click resync
Get a heads-up when an AI provider changes how it interprets system prompts, with one-click re-sync to refresh your persona against the new tuning. Stay optimized without checking the changelog yourself.
Community adapters + adapter generator
New AI launches every month. The framework includes a generator that drafts a starter adapter for any AI you name, plus a community contribution flow so adapters stay current as providers evolve.
