Introducing CogmemUI: Every Ai Model, One Interface
TL;DR: CogmemUI is a free, universal Ai interface that lets you chat with 14 Ai models from 6 providers (Claude, GPT, Gemini, Grok, DeepSeek, Mistral) in one place. It includes persistent memory powered by CogmemAi, voice chat, a model arena for blind comparisons, MCP server connectivity, 35+ slash commands, 11 server tools, and more. Bring your own API keys — no subscription required. Try it at hifriendbot.com/cogmemui.
We built CogmemUI because we were tired of the same problem every Ai power user faces: too many tabs, too many logins, too many conversations that start from scratch.
Today, we’re making it available to everyone — completely free.
What is CogmemUI?
CogmemUI is a universal Ai interface that brings 14 models from 6 providers into one workspace. Claude, GPT, Gemini, Grok, DeepSeek, and Mistral — all accessible from a single screen, with persistent memory that carries your context across every conversation.
No more copying prompts between ChatGPT and Claude. No more re-explaining your project to every new chat. No more paying for features you can get for free.
Why We Built It
Every Ai platform wants to lock you in. ChatGPT doesn’t talk to Claude. Gemini doesn’t know what you told Grok. And none of them remember you tomorrow.
We thought that was backwards. Your Ai should work for you, not for the platform. So we built an interface where:
- You own your keys. Bring your own API keys from any provider. You pay them directly — we don’t mark up anything.
- You own your memory. CogmemAi persistent memory works across all models and all conversations. Switch from Claude to GPT and your context comes with you.
- You own your workflow. 35+ slash commands, 11 server tools, visual workflows, a canvas editor, model arena, document RAG, voice chat, and app deployment — all in one place.
