AI toolkit for writing, enhancing and reversing image prompts
Upload a photo, illustration or artwork and the AI returns a detailed text prompt that can be reused to generate a similar image.
Expands a short plain idea into a richer prompt covering subject, setting, style, colour, lighting and mood, even if English is not your first language.
Analyses any image, produces a detailed description, recognises objects and answers your own questions about what it contains.
Outputs tailored for Midjourney, Flux, Stable Diffusion or general use, including structured parameters you can edit keyword by keyword.
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.
