Personal context layer
New Version Brain v1
Free during beta

Capture anything. It organizes itself.

Save pages, chats, notes, files, and Claude artifacts. Reuse them in chat across Claude, OpenAI, and Gemini.

Works with every model
One centralized memory

Everything you capture, in one memory.

Pages, conversations, notes, files, tasks, events — captured into a single memory model, so nothing ever lives in a silo.

WebpageConversationNotePDFFileImageCodeClaude artifactTaskCalendar eventSynthesis

Clip from the browser

Save the pages you choose to keep, then reference them later in chat.

Use any model

Switch between Claude, Gemini, and GPT while keeping the same saved context.

Capture files & PDFs

Drop a PDF, image, or document. Overlay reads it and makes it available for future chats.

Save Claude artifacts

Save code, SVGs, and markdown from Claude artifacts so they are easy to find later.

Inspectable retrieval

Every answer includes a trace. See which saved items were used, scored, and inserted.

Private by default

Raw prompts and vendor data aren't stored unless you opt in. Delete anything and everything Overlay derived from it goes with it.

Capture, organize, reuse.

Capture, organize, reuse.

Overlay stores what you choose to keep, connects related items, and makes them available in chat or connected tools.

Use saved context in chat with any model, or pass it into tools you connect.
Multi-model

One context layer for every model

Overlay works with Anthropic Claude, Google Gemini, and OpenAI GPT. Pick the right model for each task and keep the same saved context.

Switch models mid-thread without losing context
Shared context 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.

Why now

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.
