Turn Obsidian notes into a plan with ChatGPT

Use ChatGPT to catch changes across Obsidian meeting notes, create a linked launch checklist, and save the result back to your vault.

Ask ChatGPT to read your meeting notes, catch a changed deadline, and save a linked checklist in Obsidian. Here's the result from two fictional billing project notes:

Warplet connects ChatGPT to the vault on your Mac. See the setup steps below if you haven't connected them yet.

1. Find what changed across your notes

Put the relevant notes in a folder, or use a project folder you already have. Our Warplet Demo folder contains an engineering review from September 9 and a launch update from September 14 with deadlines for Leo and Maya.

In ChatGPT, select your Obsidian connector and ask:

Read the billing project notes in the Warplet Demo folder in Obsidian. What is the current launch date, what changed, and what still needs an owner? Give me a concise table with links to the source notes. Read the actual notes and leave them unchanged.

ChatGPT reads the Obsidian notes and identifies the September 25 launch date, the migration decision, and the unassigned rollback owner

ChatGPT found the newer launch date and carried forward the earlier decision: existing customers stay on the old billing flow. It also flagged the rollback checklist as unassigned. Check those conclusions against your notes before using them to plan work.

2. Save a usable launch brief

Now turn the answer into a note with tasks and links:

Save this as Warplet Demo/Billing launch brief.md in Obsidian. Include the launch date, the customer migration decision, and a checklist with Leo's and Maya's deadlines from the source notes. Flag the unassigned rollback owner in an Obsidian warning callout. Link back to the two source notes with [[wikilinks]]. Keep it under 180 words and leave the source notes unchanged.

Check the target path and proposed changes if ChatGPT asks you to approve a write.

3. Open the result in Obsidian

Open Warplet Demo/Billing launch brief.md in your vault. Check the September 25 launch date, Leo's September 21 deadline, and Maya's September 22 test against the source notes.

The checklist has real Obsidian checkboxes. The source links open the original meeting notes, and the warning makes the unresolved decision easy to spot. You can edit the brief in Obsidian as the project moves forward.

Connect Obsidian to ChatGPT

Keep your Mac awake, Obsidian open to the intended vault, and Warplet connected while using the connector. Community plugins are configured per vault.

  1. In Obsidian's Settings → Community plugins → Browse, install and enable Local REST API with MCP by Adam Coddington.

  1. In Warplet, add a server using the plugin's HTTP MCP endpoint, http://127.0.0.1:27123/mcp/. Enable Authorization and enter the Obsidian API key as the Bearer Token. The Obsidian setup guide shows where to find both. Use HTTPS only if you've set up a trusted certificate.

  1. Copy the URL beside Obsidian in Warplet and follow the ChatGPT connector setup, enabling Developer Mode in account settings before creating the connector. Choose OAuth and authorize with the Warplet bearer token. The Obsidian API key stays in Warplet's server settings.
  2. Enable Developer Mode in the conversation and ask: “What tools do you have available from my Obsidian vault?”

If no tools appear, check that the vault is open and the plugin is enabled. The linked setup guides cover connection errors.
