Just by talking to your AI, here's what it actually looks like. (The videos show ChatGPT.)
Save a diary by chatting
Let AI reflect and analyze
Once connected, here's what you can do just by talking to Muse, Claude, or ChatGPT.
Write a diary
The AI tidies it up and saves it to Unsent.
Read your diaries
Browse the list, or open a specific day.
Reflect & analyze
The AI analyzes based on your entries.
Look back at past you
Walk through it chronologically.
Even when you write from an AI app, your diary is saved to your Unsent account, where you can read, export, or delete it anytime.
Saved from the Unsent app
Your words pass through the AI app and are saved on Unsent's server. What you say in the conversation is handled under that AI app's own privacy policy.
Unsent is being submitted to Meta's Muse connector directory. These steps apply once it's listed.
Muse is Meta's personal AI agent. With Unsent connected, Muse can save what you tell it as a diary entry, and read your past entries back when you ask.
Find Unsent
In Muse, open Settings → Connectors and choose Unsent.
Sign in (first time only)
Tap Connect, then sign in with Google. A free Unsent account is created the first time you sign in.
Start talking
Ask Muse things like "Save this as today's diary entry" or "What have I been writing about lately?"
On the free plan, Muse can save entries without limit and read the last 30 days of your diary. With Unsent Plus (one year, pay what you want), it can read your whole diary.
"Apps in ChatGPT" is still under review, but you can use it right now with developer mode.
Works even on ChatGPT's free plan. Note: developer mode can only be set up in a web browser — not the mobile app — so do the initial setup on the web.
Open settings
Open ChatGPT in a web browser, then from the account menu at the bottom left, open "Settings" → "Apps (Connectors)".
Enable developer mode
Open "Advanced" and turn developer mode ON. This is required to add a custom MCP server.
Create an app
Click "Create app" at the top right and enter the following.

On the authentication screen, sign in with LINE or Google.
Done
When using it, attach Unsent from the "+" to the left of the input box before sending.
Unsent works in either of these Claude environments:
The steps are the same in both. Claude requires a Pro / Team / Enterprise plan.
Open the connector settings
Go to "Settings" → "Connectors" in Claude and choose "Add custom connector".
Add a new connector
Enter a name (optional) and the URL below. OAuth settings can be left blank.
