One AI workspace for GPT, Claude, and Gemini with reusable system prompts
Chat with OpenAI, Anthropic, and Google models — including GPT-5, Claude 4.5, and Gemini 2.5 — from one interface, switching models inside the same conversation.
Create a library of reusable system prompts that capture your brand voice, expertise, and rules, then apply them to any supported model instantly.
Write, edit, and refine content with AI assistance built directly into the document workflow, with shared team documents.
Upload CSV files and process them at scale, tracking progress and results in real time.

Turn rough ideas into model-ready prompts in seconds
Describe your idea and choose a target model — ChatGPT, Claude, Gemini, Grok and more — to get a prompt structured for that model rather than a generic template.
Paste a prompt you already use and the Optimizer analyses it, asks up to three clarifying questions and rebuilds a stronger, more complete version.
Save instructions for voice, context and constraints so they are applied automatically to every prompt you generate.
Every refine is tracked on a timeline for comparison and rollback, and contextual next-step suggestions keep the exploration going.
