Draft a follow-up to John at Acme — we had a call last month.
✦ Rubick added context  ·  1 deck, 2 emails, 1 call note
AI
Here's a draft based on your March 18 call notes with John, the pricing deck you sent on March 22, and his follow-up email raising the SOC 2 question:

"Hi John — circling back on our March call. Since we spoke I pulled together a one-pager on the SOC 2 timeline you flagged. Would Wednesday at 2pm work for a 20-minute walkthrough?"

How it works

From scattered to second brain
in three steps

No new app to learn. No habits to change. Just an AI that finally knows you.

1
🔌

Connect your sources

Sign in with Google. Pick which folders, channels, and labels to include — read-only access. Drive, Notion, Gmail, Slack, Calendar. Done in 2 minutes.

2
🧠

Rubick learns silently

We index your documents and conversations into your private vector store. Encrypted. Never used to train AI. Stays in sync as your work updates.

3

Use any AI as usual

Open ChatGPT or Claude. Ask anything. Rubick injects the right context — silently, before you press Enter.

Built for

People who think
for a living

Founders, consultants, VCs, executives — anyone whose work compounds across files, calls and notes.

Founders

"I asked Claude to draft a follow-up to our investor. Rubick pulled the deck, the last call notes, and the email thread. The draft was 90% there."

Consultants

"Asked ChatGPT about a market sizing question. Rubick surfaced 3 slides from a project two years ago I'd completely forgotten about."

VCs

"Before every founder call, my Claude pulls the deck, my deal memo, and the warm intro email. It's like having a chief of staff."

Executives

"My morning brief arrives at 7am — Rubick pulls what's important from yesterday's threads, plus what's on my calendar today."

Why Rubick

Stop re-explaining
yourself to AI

Every new chat starts from zero. Rubick fixes that — once, across every AI you use.

🔄

Zero copy-paste

Rubick finds the right context across all your sources and injects it silently — before you press Enter. You just write the prompt.

🌐

One memory, every AI

ChatGPT, Claude, Cursor. Your memory follows you across every tool — no lock-in to a single vendor.

🔒

Privacy-first by design

Read-only access. Encrypted at rest. Never used for training. Granular controls — exclude any folder, contact or keyword. One-click delete.

Why not just use
ChatGPT Memory?

About your data —
read this before signing up

You're not going to connect your Gmail to a startup just because we asked nicely. So here's exactly what happens.

👁

Read-only access

We never write to your Drive, Notion, Gmail or Slack. Only read what you've explicitly selected.

🔐

Encrypted at rest

Your vector index is encrypted. Our engineers cannot read your data. AWS Frankfurt by default. US region available.

🚫

Never trained on

Your data is never used to train AI models. Period. Written into our DPA — verifiable on request.

🗑

One-click delete

Pause indexing or delete everything in one click. Your index is gone within 24 hours.

FAQ

The questions you
actually have

Where exactly is my data stored?
Your vector index lives on AWS in Frankfurt (default) or Oregon (if you choose US). Your original files never leave their source — we just read them. You can delete your index anytime; it's gone within 24 hours.
Can I exclude specific folders or contacts?
Yes. Before connecting, you choose what's included. After connecting, you can exclude anything at any time. Specific Drive folders, Slack channels, contact emails, or keywords — your call.
Will Rubick ever train AI models on my data?
No. Never. Your data is yours. We don't fine-tune on it, we don't share it with third parties, we don't sell it. This is written into our Data Processing Agreement.
How is this different from ChatGPT Memory?
ChatGPT Memory only works in ChatGPT, and only remembers what you've told ChatGPT directly. Rubick works in every AI you use, and remembers everything from your actual files and conversations — automatically.
How is this different from Glean?
Glean is for entire companies. It's expensive, requires IT, and only works inside Glean's own AI assistant. Rubick is for you, the individual — and works inside the AI tools you already love.
How is this different from Mem.ai?
Mem.ai is a notes app with AI. Rubick is the layer that makes any AI smarter about you. We don't replace your notes — we connect them to ChatGPT, Claude, Cursor.
What happens if I cancel?
Pro/Power plans → Free tier. You keep your index for 30 days in case you want to reactivate. After 30 days, your index is permanently deleted.
Do you support Claude Desktop / Cursor via MCP?
Yes. We provide an official MCP server for Claude Desktop and Cursor. Setup is one config file. Listed in the public MCP registry.
I'm in a regulated industry (legal/healthcare/finance). Can I use Rubick?
Talk to us. We support custom data residency, BAA, and dedicated infrastructure for compliance-heavy use cases. Email enterprise@rubick.fyi.
