ModelCaddy

Capture AI conversations locally, continue them across supported AI sites, and unlock shared Memory with the ModelCaddy app.

ModelCaddy — the private, local-first memory for your AI chats. Capture your conversations from all major AI platforms — Claude, ChatGPT, Gemini, and more — with just one click. Everything is saved locally on your computer — ModelCaddy never uploads your conversations to any cloud service. Extension features NEW • Quick start checklist — adopt your Vault, pin the extension, sync your first chat, and scan your history; progress you can collapse once you're rolling • Scan your whole history — one click per site brings in everything you've already discussed, not just what you capture from now on • Picks up where it left off — chats you already have are skipped, so you can press Scan again any time • Carry a whole conversation forward into your next AI chat — no retyping, no copy-paste • Privately tracks your open chats without even thinking • One-click capture of the AI chat you're in, saved to a local folder you choose • Automatic re-saving as a tracked chat keeps going • Save selected text from any webpage NEW • One right-click: "Save to ModelCaddy" — a selection clips, a picture saves as a picture, anything else saves the page (needs the desktop app for a page save) NEW • Every saved page carries a picture of itself — a screenshot of the tab, filed next to what it said • Originals preserved as source evidence ModelCaddy desktop makes it even better • Smart semantic search across all your captures, even when you can't recall the exact words • On-device AI that organizes captures into per-project memory • Drop relevant project context into new conversations automatically Your conversations stay on your machine. Scanning reads your history through your own signed-in browser session, and the extension talks only to your own computer — never to a ModelCaddy server. When the desktop app is running, the extension finds it on your machine even if the usual local port is already in use. The desktop app is optional and currently for macOS — Download now for FREE at modelcaddy.com/download.
