Fable sidebar for Claude: 1-click prompt templates + sort your chats into folders with pins & search. Made for Claude Fable. Fable adds a sidebar to Claude that does two things you've been missing: a ready-to-use prompt library and a proper chat organizer.
PROMPT LIBRARY Browse 35+ built-in prompt templates across Writing, Coding, Analysis, Learning, Creative, and Business — click any card to instantly drop the prompt into Claude's composer. Save your own reusable prompts under "My Prompts" and search everything in one keystroke.
CHAT ORGANIZER Create folders, move conversations into them, pin your most-used chats, and search across everything you've saved. Fable reads the chat sidebar you already have and lets you reorganize it without touching Claude's own UI.
