Everything you need to know about c137 - the AI that organises itself.
Three things set c137 apart: Auto-sorting that organises your chats into folders and projects automatically, smart context that pulls from your entire conversation history, and interest profiles that learn your preferences over time. You get a truly personal AI that improves the more you use it.
Just talk. The Core analyses your conversations and automatically files them into relevant folders and projects. No tagging, no manual organisation - everything is sorted for you based on content and context. It's like having a personal assistant who keeps your second brain tidy.
Yes, automatically. Every new chat knows what you've talked about before. c137 smartly retrieves relevant context from your entire history - no need to copy-paste or start from scratch. Your conversations build on each other naturally.
We use our own combination of models optimised for different tasks - including Grok, GPT, and Llama. We're also adding support for bringing your own API keys soon, so you can use your preferred models directly.
Yes! The Free Taster gives you full access to all features with limited usage. It's the complete c137 experience so you can try before you buy. Once your usage runs out, memory is retained for 14 days.
Smart context retrieval means we only load what's relevant, cutting costs dramatically. We built c137 from scratch for efficiency, not on top of legacy systems. The £5 beta price is locked for life - it will increase at launch, but early adopters keep this rate forever.
