Claude as Your Notes App: Stop Losing Things Between Sessions
Claude is the best note-taker you've ever used — until the session ends. Then it's gone. Here's how to fix that in 30 seconds.
The problem: Claude resets
Every Claude session starts from scratch. No memory of what you told it last week, last month, or five minutes ago in a different tab. For short tasks, this doesn't matter. For anything that builds over time — notes, decisions, contacts, projects, ideas — it's a real limitation.
You've probably worked around it by:
- Pasting old conversations into new sessions
- Keeping a separate notes app running alongside Claude
- Keeping everything in one very long session until it gets unwieldy
- Using Claude's Projects feature and hitting the custom instructions limit
None of these are satisfying. What you want is Claude that already knows what you've told it — not Claude that you have to brief every session.
What an AI notes app actually needs
A notes app that works with Claude needs three things:
- Write — Claude can save something without you switching to another app
- Search — Claude can retrieve notes by meaning, not just exact wording
- Persist — notes survive session ends, tab closes, and app restarts
Standard Claude has none of these (custom instructions are static and space-limited). Stash adds all three via an MCP connector.
How Stash works as a notes layer
Stash is a remote MCP server. You add a connector URL to Claude once, and from that point on Claude has two new tools: add() to save records, and search() to retrieve them. Both work in natural language. You don't need to know any of this — you just talk to Claude and it handles it.
In practice:
You: "Note this down: the Hendersons want a quote by Friday,
budget around £2,000, they're flexible on materials."
Claude: Saved to your jobs collection.
[Stash: added record to jobs collection, id 4891]
Later, in a completely new session:
You: "Who needs a quote this week?"
Claude: The Hendersons — they want a quote by Friday,
budget around £2,000, flexible on materials.
[Stash: searched 'quote this week' → 1 result]
That's it. No app switching. No copy-paste. Claude saves and retrieves, you just ask.
What people use it for
Meeting notes and decisions
End of a call: "Save this: we agreed to move the launch to July 14, Priya owns the copy, Tom owns dev. Budget increased by £500." Next session, before you start work: "What did we decide about the launch?" Claude retrieves it.
Ideas and observations
Things that occur to you mid-conversation that you don't want to lose. "Note this idea: subscription fatigue as an angle for the positioning piece." It's there next week when you come back to the positioning piece.
Reference information
Client details, supplier contacts, account numbers, preferences. The things you look up repeatedly. Save them to Stash once; Claude retrieves them in context when you need them.
Learning notes
When Claude explains something well and you want to keep it: "Save a summary of this explanation to my learning notes." Next time you're working in the same area, it's there.
Decisions and rationale
Why you chose Stripe over Paddle, why you went with this supplier, why you rejected that approach. The context that makes a decision make sense six months later.
The context() pattern: load what matters each session
Stash includes a context() tool that Claude calls at the start of each session. You fill it with standing context — who you are, what you're working on, your priorities — and Claude loads it automatically.
Instead of pasting a briefing every time, you type: "Let's work on the client project" and Claude already knows who the client is, what the project is, what's outstanding, and what your preferences are.
This is the pattern that makes Claude feel less like a chatbot and more like a working assistant.
How it compares to other approaches
| Approach | Search | Persistent | In-Claude |
|---|---|---|---|
| Pasting old chat into new session | No | No | Painful |
| Custom instructions | No | Yes | Space-limited |
| Separate notes app | Depends | Yes | No |
| Claude + Stash (MCP) | Yes | Yes | Yes |
The advantage isn't just convenience. It's that Claude can search your notes in context — it doesn't just retrieve records, it uses them to give better answers.
Setup: 30 seconds
- Go to stashlite.com → sign in with Google → you get a connector URL.
- In Claude: Settings → Connectors → Add custom → paste the URL → sign in with Google.
- That's it. Claude can now save and search notes in every session.

Stash is not a full note-taking app. You can't browse your notes in a fancy editor, add images, or nest pages. It's a fast, searchable record store that Claude talks to. The interface is Claude itself.
If you want rich note management with nested docs, tags, and visual organisation, a dedicated notes app is the right tool. If you want Claude to remember things you've told it and find them intelligently — Stash is the right tool.
