Integrations

Your key. Your models. Your brain, everywhere.

Zsper is not a walled garden. Run it on your own provider key, and expose your knowledge to whatever LLM you already use — safely, with no lock-in.

New · Now in Claude

Zsper is live in the Claude directory.

No token to copy, no config file. Find Zsper in Claude's connector directory, sign in, and Claude can read your brain while you write — then sync finished drafts and new stances back, every save waiting for your review. Works in Claude on the web, desktop, and Claude Code.

Bring your own key

Run on your own account, on your own terms.

Add your Anthropic or OpenAI key and Zsper routes AI work through it — so your spend is transparent and portable.

  • Encrypted at rest

    Keys are stored with AES-256-GCM. We never log or surface the raw key.

  • Your keys, your bill

    BYOK usage is billed by your provider — never charged by us. Your Zsper plan stays a flat $9, no matter how much you draft.

  • Still metered

    We meter BYOK usage so you keep full visibility and a fair-use cap, at zero cost to you.

MCP connectors

Plug your brain into any LLM.

Zsper speaks the Model Context Protocol — the open standard for connecting LLMs to external data. Your knowledge stops being trapped in one app.

  • Read-only by construction

    External clients can read your brain, never change it. No mutation, ever.

  • Scoped to one workspace

    A token grants a single workspace — no cross-workspace access, and suppressed or proposed records stay hidden.

  • Revocable instantly

    Rotate or revoke any token from Settings the moment you want to cut access.

Setup

Connected in three steps.

01

Mint a connector token

In Settings → Connect your brain, generate a scoped Bearer token for one workspace.

02

Add the endpoint to your client

Point Claude, ChatGPT, or any MCP client at your endpoint with the token. Two minutes, no code.

03

Ground your assistant in your brain

Your assistant can now search and fetch your real opinions, stories, and articles — a cold email, a client proposal, an investor update, all standing on what you actually know.

On Claude, skip the token — it's a one-click connector in the directory. Want the deeper details? Read the full guide to BYOK + MCP →

FAQ

Questions, answered.

Can I use my own model key?+

Yes. Bring your own Anthropic or OpenAI key — encrypted at rest, metered for your visibility, and never billed by us. Your provider bills the usage; your Zsper plan stays flat.

Can a connected tool change or publish my content?+

No. External clients read your brain scoped to one workspace, and anything they save lands as a proposal or a draft waiting for your review. There are no publish or delete tools — by construction.

Which AI tools can connect?+

Claude is one click from the directory. Anything else that speaks MCP — desktop clients, editors, agents — connects with a scoped token from Settings in about two minutes.

How do I cut access?+

Instantly, from Settings → Connect your brain. Revoke a token or disconnect Claude and access ends immediately — no support ticket needed.
