Show HN: Inkfold – workspace across multiple AI providers with shared memory
Inkfold is a platform that provides shared memory across multiple AI providers like ChatGPT, Claude, Gemini, Grok, and more. It captures conversations, builds structured context, and injects relevant memory into new chats, eliminating the need to re-explain yourself. It offers smart, private, or incognito retention modes and subscription or pay-as-you-go pricing. Suitable for individuals, teams, and organizations.
Inkfold — your AI tools, one memory
Your AI tools, one memory
For people who pay for more than one AI — keep your memory and context as you move between ChatGPT, Claude, Gemini, Grok, and the rest. Stop re-explaining yourself every time you switch tools.

How it works
Sign in once. Every AI catches up.
Inkfold indexes your conversation history, builds structured context, and injects the right signal into every new chat — on any vendor, on any device.
01 / CAPTURE
Connect your tools
Import existing chats from ChatGPT, Claude, DeepSeek, Gemini, Grok, Perplexity, and more. Chat through the Inkfold web app, CLI, or mobile app to capture new conversations as they happen.
02 / REMEMBER
Your memory builds
Inkfold extracts entities, decisions, and preferences from each conversation. Three signal layers — your history, topic patterns, and crowd-sourced domain signal — stack to produce context that gets sharper over time.
03 / INJECT
Every AI catches up
Start a chat on any vendor. Inkfold picks the best model for the task, adds relevant memory, and streams the answer. Your AI finally knows your project.
Who it's for
Built for people who take AI seriously.
Power users
You pay for more than one AI
You have ChatGPT Plus, Claude Pro, Gemini Advanced, and maybe Grok on top. Each one knows nothing about the others. Inkfold gives all of them the same memory — your projects, your preferences, your context.
Teams
Your whole team, one shared memory
Your team uses different AI tools for different tasks. Inkfold lets everyone share memory across vendors — so the context one person builds today is available to the next person who needs it.
Organizations
