MTC, or Marcus Tullius Cicero, is a GPT designed to serve as a mentor in the art of prompt engineering, providing guidance and imparting wisdom on effective communication to enhance interactions with AI.
This tool is intent on fostering valuable conversations, helping users formulate effective prompts for a wide range of contexts, including problem-solving, ethical discussions, learning about a new domain, crafting historical depictions, prompting for counterarguments, and encouraging philosophical discourse.
MTC also guides the construction of prompts for diverse topics, aimed at nurturing creativity, promoting innovation, and encouraging the engagement of thoughtful and comprehensive dialogues.
Leveraging the outputs from the base model, ChatGPT, it provides model responses to various queries, showcasing the potential versatility of complex AI dialogues.

Unified Memory for all of your AI apps16,27817Released 1mo agoNo pricingHey TAAFT! ๐ I'm Advait from OpenGradient, and we're thrilled to launch MemSync - a unified memory layer for all your AI apps. Why we built this: Like many of you, we were frustrated by AI's amnesia problem. Every time we switched between ChatGPT, Claude, or Perplexity, we had to start from scratch - re-explaining our context, preferences, and ongoing projects. The most advanced AI models in the world couldn't remember a conversation from yesterday. What's unique about MemSync: - Universal compatibility: One extension that works across ALL major AI platforms - not locked to a single tool - Intelligent context sync: Your conversations flow seamlessly between different AI models - Privacy-first architecture: End-to-end encryption ensures your memories stay yours - Zero setup friction: Install once, and every AI tool instantly remembers you What we're most proud of: The simplicity. While others are building complex integrations, we focused on making memory "just work." Users tell us it feels magical when Claude picks up exactly where ChatGPT left off. One founder said it's "like giving AI a shared notebook about me that actually persists." We've been quietly testing with a small group, and the feedback has been incredible - people save 15-30 minutes daily just from eliminating repetitive context-setting. Today's launch includes our Chrome extension with support for ChatGPT, Claude, Grok, and more coming soon. Relevant Links: โข Website: https://www.memsync.ai/ โข Github: Open-source soon!
