Editor's note
Thinking Claude was a two-part project designed to elicit more deliberate, step-by-step reasoning from Claude 3.5 Sonnet on the Claude.ai web interface before Anthropic introduced native extended thinking. The first component was a versioned set of custom system prompt instructions, stored as markdown files (the most recent being v5.1-extensive-20241201), which users pasted into Claude.ai's custom style instructions to guide the model through a thorough internal monologue before answering. The second component was a Chrome extension (v3.2.3, also available on the Chrome Web Store) that rendered those verbose thinking blocks as collapsible, copyable sections, making long reasoning traces manageable in the browser. The project targeted everyday Claude.ai users on both free and Pro tiers who wanted greater transparency into how responses were constructed. The repository has since been retired, with the author noting that Claude's built-in reasoning capabilities now make the external prompting approach unnecessary.
Tools overview
Caution
This repository has been retired. Claude is already a reasoning model with strong built-in thinking capabilities, making this project no longer necessary. Thank you to everyone who contributed and supported Thinking Claude!
Thinking Claude
Let Claude think comprehensively before responding!
A super quick reminder: Thinking claude is not aimed for benchmarks or huge leaps in math or something, since those are pre-determined by the base model (new Claude-3.5 Sonnet). I only want to explore how further we could reach with Claude's "deep mindset". That said, when using it in your daily tasks, you will find Claude's inner monolog (thinking process) very very fun and interesting.
