# Can Claude read my Gmail or Outlook inbox?

Connect Claude to Gmail and it can search your inbox. Ask it to find the thread about the contract, and it will.

Then a week later you ask Claude to act on what you agreed in that thread, and you are back to digging. It found the message when you pointed at it. It did not keep the agreement.

The inbox gave Claude search. It never gave it memory.

## What an inbox actually gives Claude

Email is a firehose. Hundreds of threads, most of them noise, a few of them load-bearing. Claude can search it well: tell it roughly what you are looking for and it surfaces the message.

That is real and useful for "find the email where we agreed the price."

But search only works when you already know the fact exists and go looking. It will not, on its own, remind you next month that the price was conditional on a two-year term. That detail is back in the pile the moment the conversation moves on.

## A thread you can find is not a decision you can rely on

This is the gap. People connect Gmail expecting Claude to "know what we agreed," and Claude can *retrieve* what you agreed if prompted, not *retain* it.

The decision is in there, on line nine of a forwarded thread, under three "sounds good"s. Finding it again every time is not the same as having it.

Claude needs the durable version, distilled and standing on its own.

## What Claude needs from your email

Not the whole inbox. When an email actually contains something that matters, a few sentences:

- The decision, commitment, or deadline
- Who it involves and who owns it
- The condition or caveat attached
- The next step

Saved once, in a place Claude reads without searching the firehose again.

## Keep the inbox. Add the memory layer.

Hjarni is a Markdown knowledge base with a built-in MCP server. It does not replace Gmail and does not manage your inbox. It is where the facts worth keeping live.

It ships with a [decision log template](/templates/startup-decision-log) and a [project memory template](/templates/developer-project-memory), both structured around exactly what Claude needs: the decision, the owners, the caveat, and the next step.

Your inbox stays the source. Hjarni becomes the memory. Claude reads the memory.

## How it works with Claude and ChatGPT

Connect Hjarni's built-in MCP server. It takes five minutes. ([Claude guide](/docs/connect-claude-mcp), [ChatGPT guide](/docs/connect-chatgpt-mcp)) For the integration overview, see [Hjarni for Claude](/for/claude).

Connecting Gmail or Outlook themselves happens inside your assistant, not in Hjarni; for that side, see [Claude's integrations overview](https://claude.com/blog/integrations) and [ChatGPT's connectors guide](https://help.openai.com/en/articles/11487775-connectors-in-chatgpt).

When an email lands a real decision, drop the few sentences that matter into a Hjarni note. The next time you work on that project, ask Claude to read the note first.

Your inbox has the forty-message thread. Your Hjarni note says you agreed to the price on a two-year term, pending legal sign-off. Claude drafts the next email from the note, not from forty messages it has to reread.

The note behind that reply is just as short:

```
Pricing thread, Vendor X, 24 Jun
Agreed: $40k, on a two-year term.
Condition: pending their legal sign-off.
Owner: me, to send the countersigned MSA.
Next: chase legal if no reply by Tuesday.
```

It is the same pattern behind giving [Claude real meeting context](/blog/ai-meeting-assistant-that-works-with-claude), with the decision buried in a thread instead of a transcript: keep the inbox you live in, and save the decisions where your AI can reuse them.

## Set it up

1. Create a free Hjarni account at [hjarni.com](https://hjarni.com)
2. [Connect Claude](/docs/connect-claude-mcp) or [ChatGPT](/docs/connect-chatgpt-mcp) to Hjarni's built-in MCP server
3. Start from the [decision log](/templates/startup-decision-log) or [project memory](/templates/developer-project-memory) template
4. Ask Claude: "Read my note on this before you answer."

Keep Gmail or Outlook for the conversation. Give Claude the decisions.
