All-in-one personal AI
Overlay remembers what you read, write, ask, save, and decide — and brings it back into every chat. One brain. Any model. Yours.
One memory model. Every kind of content.
Webpages, conversations, files, Claude artifacts, tasks, events — all captured in a single artifact model so any one can reference, link, or be retrieved alongside any other.
Browse with memory
The extension watches the pages you choose to keep — clip, save, and chat with them later. The Brain remembers what you've seen.
Any model, one memory
Claude, Gemini, or GPT-4 — switch freely. Your Brain travels with you across every provider.
Capture files & PDFs
Drop a PDF, image, or document. Overlay chunks, embeds, and links it into your Brain so future chats can find it.
Save Claude artifacts
Code, SVGs, markdown — pull artifacts straight out of Claude into your Brain, ready to be referenced from any conversation.
Inspectable retrieval
Every answer comes with a trace chip. See exactly which memories were retrieved, scored, and injected — or correct them.
Private by default
Raw prompts and vendor blobs aren't stored unless you opt in. Delete any artifact and its chunks, embeddings, and traces go with it.
How the Brain works
Five layers, one memory. Raw artifacts flow up the stack into chunks, abstractions, a graph, and synthesis — then back down into every chat.
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.
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 chip on any assistant reply to see exactly which artifacts, chunks, and claims were injected.
Correct & dismiss
Claims aren't facts. Mark them as wrong, supersede them, or pin the ones that matter — your Brain learns what you trust.
Forget anything
Delete an artifact and its chunks, embeddings, claims, links, and traces go with it. Privacy defaults are conservative on purpose.
Web today. Everywhere next.
Start with the web app and Chrome extension. CLI, public API, MCP server, and iOS capture are on the way.
Web app
Open the Brain workspace, ingest URLs and files, inspect every trace.
Browser extension
Clip pages, drop into chat, save Claude artifacts — straight from your browser.
Public API
Push artifacts and query memory with API keys. Stable /api/v1 with key prefixes.
MCP server· Soon
Expose your Brain to Claude Desktop, Cursor, and any MCP-aware tool.
CLI· Soon
overlay ingest, overlay search, overlay trace — your Brain from the terminal.
iOS app· Soon
Capture from share sheet, ask your Brain on the go, sync everywhere.
The personal AI moment is finally here
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.
"The long-running thread of Software 2.0 and personal LLMs: a future where you talk to your own model, with your own context, instead of a generic one."
"Tools for thought and the "second brain" workflow keep coming back because the problem is real — your knowledge is scattered across 12 apps that don't talk."
"Capture, organize, distill, express. The discipline that millions of knowledge workers already practice — Overlay automates the boring half."
"Note-taking apps figured out the graph. LLMs figured out language. Overlay is what happens when you put them in the same memory."
These are public ideas from the personal-AI conversation, not endorsements. We're building one answer to the same question they've been asking.

"Finally an AI that doesn't make me re-explain my project every morning. The Brain remembers the docs I clipped, the decisions I made, and the dead-ends I already hit."
Sarah Johnson
PM, infra startup
"I bounce between Claude and Gemini all day. Overlay is the only place my context lives in one shape — everything else feels like starting over."
Michael Chen
Software engineer
"The retrieval trace is the part that sold me. I can see exactly which note, page, or claim it pulled — and tell it when it's wrong."
