What It Actually Is
An iOS mobile app with sync, folders, and search, plus an exposed surface your agents can use directly.
Claude, add that to my notes.
A notes app on your phone claude/openclaw can actually edit. Curious if this is actually useful or a dumb/reptitive idea.
A lot of apps now ship with their own assistant built in, but I don't think that's the right approach. You already presumably have an agent that you use a lot. You should be able to keep chatting with that agent and have context across products, not switch into a separate AI silo for every task.
This has a lot of applications, but one simple place this shows up is in notes apps, where many products embed their own AI agent. I’d much rather have the same Claude I talk to every day be able to read and edit notes on my phone directly instead of using a separate, app-specific agent that has no context beyond the notes app.
So basically built an IOS app with an exposed endpoint with integrations provided into Claude Cowork (.mcpb file) and OpenClaw (skill + npm package). Been using it a fair amount myself, and I actually like it quite a bit.
If that sounds interesting to you, download on testlfight to give it a shot. If not, would be interested to hear general thoughts.

How to Install
1. Claude Cowork
Download the .mcpb file, double-click it, and
log in.
2. OpenClaw
First make sure you have npm installed, then install the
skill named northbase.
npm i -g clawhub
clawhub install northbase
3. Manual
npm install northbase
northbase login
Most “AI notes apps” want to own the assistant relationship.
Northbase does the opposite. It gives your existing agent a shared
workspace with you.
Why It Feels Different
It is not a notes app with a trapped in-app assistant. It is a notes workspace shared by you and your external agent.
What Northbase Is
Three Surfaces, One Shared Workspace.
Northbase is not just one app screen. It is a phone interface for you, a developer surface for code, and an agent surface for tools. All three point at the same notes.
iOS App
Write and read notes on your phone with sync, folders, and search. The phone remains the human interface.
Exposed Notes API
Your notes are available through an exposed surface instead of being trapped inside a closed product experience.
Agent Access
Install the extension or use the MCP tools directly so your agent can read, write, list, and organize the same notes.
Why It Matters
Agent Allowed In. Agent Not Built In.
The product thesis is not “put AI inside notes.” It is “let your broader personal agent work with your notes.” That difference sounds small, but it changes the whole shape of the product.
When every product ships with its own assistant, context gets fragmented. One assistant knows your notes. Another knows your calendar. Another knows your code. You end up with many smart islands and no real working partner.
Northbase is built for the opposite direction. You already have an agent relationship forming around tools like OpenClaw and Claude Cowork. That agent should understand your notes too, because your notes are part of your real context.
So Northbase does not try to replace your agent with a new one. It gives your existing agent permission to enter the workspace, act on the same artifacts, and write back to the same place you use on your phone.
What You Do
Write down ideas, tasks, drafts, and context on your phone the moment they occur.
What Your Agent Does
Reads the same note, updates plans, organizes folders, or writes a response back into your workspace.
What You Avoid
Another app-specific assistant with isolated memory and a job scope that ends inside one product.
What You Get
One notes space that works across phone, code, and your preferred external agent.
For Developers
Use the App. Wire It Into Your Stack.
The iOS app is where the notes live. The npm package and MCP surface are how you bring those notes into your own tooling, automations, and agent workflows.
northbase npm Package
JavaScript API client for developers who want to read and write Northbase notes from code.
npm install northbase
Claude Desktop Extension
Fastest path to agent access. Install the .mcpb
once and expose Northbase to Claude Desktop.
