ChatGPT
Use your saved research in ChatGPT
Add Stacks to ChatGPT as a custom MCP server, then turn it on in a chat. ChatGPT can search the articles, posts and notes you saved with Stacks, read them, and answer with links back to your saves.
Connect Stacks to ChatGPT
- 1Open ChatGPT on the web (chatgpt.com).
- 2Go to Plugins, click + and choose Add custom MCP server.
- 3Name it Stacks and paste
https://app.betterstacks.com/api/mcp - 4Choose OAuth and sign in to Stacks.
- 5In a chat, turn Stacks on from the + menu and ask about something you saved.
Custom MCP servers need a paid ChatGPT plan and aren’t available in every workspace.
ChatGPT memory is full. What now?
ChatGPT’s saved memories are short facts about you: your job, your preferences, how you like answers written. That space is limited, and when it fills up ChatGPT stops adding new memories until you delete some.
Memory was never meant to hold the material itself: the articles you read, the posts you bookmarked, the notes you took. Keep those in Stacks instead. They don’t count against ChatGPT memory, ChatGPT fetches only what a question needs, and the same saves work in Claude too.
A simple split: let ChatGPT memory keep who you are; let Stacks keep what you’ve read. More in Stacks vs ChatGPT memory.
What you get
- ChatGPT finds saves by description, not just by title.
- It reads the full page, with your notes and highlights.
- Answers link back to your saves, so you can check the source.
- You can save from the chat: “Save this link to Stacks with a note.”
- It never deletes anything. Remove the connector and access stops.
Questions
Can ChatGPT read my bookmarks?
Not on its own. Save or import your bookmarks into Stacks (the extension imports browser bookmarks, X bookmarks and LinkedIn saved posts), then connect Stacks to ChatGPT as a custom MCP server. ChatGPT can then search and read them.
What happens when ChatGPT memory is full?
ChatGPT stops saving new memories until you delete some in ChatGPT’s memory settings. Keep long material like articles and notes in Stacks instead: it doesn’t use ChatGPT memory, and ChatGPT pulls it in only when a question needs it.
Do I need ChatGPT Plus?
Custom MCP servers need a paid ChatGPT plan, and some workspaces turn them off. On a free ChatGPT plan you can still use Stacks in Claude, or ask in Stacks itself.
Is Stacks free?
Yes. The free plan includes 20 asks a month across Stacks, ChatGPT and Claude, with keyword search in the connector. Be Productive ($36 a year) adds unlimited asks and search by meaning. Your first ask starts a 30-day trial of everything.
Can I save ChatGPT answers to Stacks?
Yes. With the Stacks extension, a Keep button sits next to Copy on each ChatGPT reply. With the connector on, you can also ask ChatGPT to save a link or a note to Stacks.
