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.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
