Overlay captures what matters, organizes it into one connected memory, and synthesizes new understanding over time — kept ready to use in any chat, or any tool you connect.

How your memory evolves
Step 1
Capture
Pages, files, chats, notes — saved in one place, exactly as they were.
Step 2
Organize
Sorted and connected automatically, so related ideas link up.
Step 3
Synthesize
Throughlines, recurring questions, and contradictions surface on their own.
Step 4
Evolve
Your memory sharpens as you use it — ready for any model or tool.
On every answer

Step 1
Capture
Clip a page, drop a file, save a chat, or just talk. Anything worth keeping becomes part of your memory.
Step 2
Organize
Overlay sorts and connects what you capture, linking related ideas so nothing lives in a silo.
Step 3
Evolve
It surfaces the right memory in any chat — with any model — synthesizing new insights as you go, and ready to plug into the tools you use.
Multi-model
One brain, every frontier model
Overlay routes through Anthropic Claude, Google Gemini, and OpenAI GPT — pick the right one for each task. The Brain, your context, and your memory stay the same.
Switch models mid-thread without losing context
One memory shared across every provider
Use the best model for each task — Sonnet for code, Gemini for long context, GPT for reasoning
Inspectable & private
An AI you can audit
Every retrieved memory is logged with a trace. Vendor blobs and raw prompts aren't kept by default. You can correct, archive, or forget any artifact.
Trace every answer
Click the trace on any assistant reply to see exactly which memories were used.
Correct & dismiss
Not everything Overlay remembers is right. Mark something wrong, replace it, or pin what matters — your memory learns what you trust.
Forget anything
Delete something and everything derived from it goes too. Privacy defaults are conservative on purpose.
Reuse & rewire
Your memory becomes building blocks
Nothing stays locked in a silo. Pull any memory into a note or a chat, connect ideas with backlinks, and ground every answer in what you already know.
@-mention anything
Type @ to drop any saved page, note, file, or task straight into a chat or a new note — instantly wired back to its source.
Compose from memory
Write notes that reference your other memories. Backlinks keep everything connected, so ideas compound instead of scattering.
Ground every chat
Ask anything and the answer is wired to your real context — the pages, decisions, and notes you've already captured.
Use it anywhere
Web today. Everywhere next.
Start with the web app and Chrome extension. CLI, public API, MCP server, and iOS capture are on the way.

Builders and researchers have been calling for it for years: an AI that's actually yours, with your context, your memory, your taste. Overlay is one shape of that idea.
