Independent guide and prompt workspace for the Fable 5 model
Specs, context window, output limits and API pricing for Fable 5 presented next to other Claude models, each figure labelled with a date and source.
Tracks where the model is reported as available — Claude apps, the Claude API, cloud platforms, GitHub Copilot and router catalogues — as the situation changes.
Dozens of ready-to-copy prompts for creative writing, research, coding, marketing, learning, productivity and safety review.
A no-account streaming chat plus a single-prompt playground for refining structure before spending tokens on a real frontier model.
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.
