Key Features of Blue Comet
Discover the powerful features that make our AI-enabled client the ideal choice for Claude / Anthropic API

No Multi-Hour Usage Penalties
Unlike Claude's web client, be able to use Anthropic's API continuously without those terrible multi-hour lockouts. Get proactive warnings when nearing Anthropic's token or usage limits. Also control which model you use and how much session context to maintain to make best use of your resources.

Customizable Experience
Blue Comet offers a customizable platform that adapts to your unique requirements. You can tailor the client to fit your preferences perfectly.

One-Click Prompt Enhancer Delivers Better Results
Blue Comet uses Anthropic itself to create rich, value-added prompts to allow you to get the most out of every prompt.

Instant Recaps of Long Threads, with Suggested Next Steps
As you find yourself using the tool more and more, threads get longer, so it is nice to be able to get a quick recap of where you are and suggestions where to go next!

Powerful Search & Navigation
AI-powered search makes finding past conversations effortless (We search thread names and the full conversations too). Roll-over effects showing thread creation and last-modified timestamps help you locate the right thread in a hurry.

Nice Tools for Managing Code
No more tough-to-read white streams of code. We add line numbers and smart color-coded markup to make AI-generated code easier to digest and errors easier to trace.

Great Library Functions for Managing Your Favorite Prompts
Want to have a great means to store and find prompts you love? We have a powerful integrated prompt library, allowing you to store, tag, and search for the perfect prompt. To help, we have included 300+ prompts to use to help you leverage the full power of the Anthropic AI.
