Every week, ChatGPT or Claude gives you something genuinely useful: a recipe that worked, a plan you intend to follow, a paragraph that finally says what you meant. A week later it is buried in a sidebar of chats with names like “New chat”. The fix is not a better memory — it is a notepad your AI can actually write in. That is what Thoughts becomes when you connect it with MCP: a permanent, searchable shelf on your iPhone where an assistant can save an answer the moment it is good, filed in the right project, ready to find again without reopening the conversation.
Why AI chats are a bad filing cabinet
Chats are organised by conversation, not by topic. One thread about dinner drifts into substitutions, timings for a different dish, and a shopping list for Saturday. The useful artefact — the final recipe — sits somewhere in the middle of a negotiation. Copying it into a notes app by hand works, but it breaks formatting, drops context, and mostly does not happen when you are busy. Screenshots are worse: unsearchable and unreadable a month later.
There is a subtler problem too. A chat preserves the back-and-forth, but what you need later is usually the conclusion. “What did we decide?” matters more than the six messages that got there. A notepad stores conclusions.
What “a notepad for your AI” actually means
With Thoughts connected, your assistant gains a small, deliberate set of abilities. It can look at your synced projects, search your thoughts, read one in full — and, when you ask, save a new thought or create a project. It cannot edit or delete what you have, and it cannot see notes you keep local or locked. You remain the editor; the AI becomes a very fast contributor who files things properly.
In practice the loop is three steps. Work something out in chat. Ask for the keepable version. Save it where it belongs:
Tidy that into a final version I can keep: title, short intro, then the steps. Then save it as a thought in my Recipes project.
That single sentence does three jobs people usually skip: it distils the thread, formats the result for rereading, and files it before the moment passes. Setup takes a few minutes — follow the ChatGPT connection guide or the Claude connection guide, depending on which assistant you live in. Both write to the same library.
Five things worth saving (and how to ask)
1. Recipes you will cook again
Write the final recipe with ingredients first, then numbered steps and timings. Save it in Recipes.
Recipes are the clearest win because you need them with floury hands, in an app that opens fast and reads well. The dedicated guide to saving recipes from ChatGPT covers ingredients, scaling and shopping lists in detail.
2. Lists that leave the house with you
Turn that into one grocery list grouped by shop section, quantities included. Save it as this week's list.
Grocery lists, packing lists, errand runs: anything you will check on your phone while standing somewhere. See making a grocery list in ChatGPT and saving it to Thoughts.
3. Decisions and next steps
Summarise what we decided and the next three actions. Save it in the Launch project.
Decisions evaporate fastest because they feel obvious in the moment. A dated thought that says what was decided — and what was deliberately not decided — saves a surprising number of repeat debates.
4. Drafts in your voice
Save that draft exactly as written in Writing. I will edit it in Thoughts later.
The chat is where you generate; the note is where you finish. Editing in Thoughts keeps one canonical version instead of five chat variants.
5. Explanations you will need twice
Save a short version of that explanation in Reference, with the example included.
How your boiler's timer works, what that error message meant, the visa rule you looked up: if you asked once, you will ask again. A saved note answers instantly and offline.
Keep the notepad worth opening
A notepad your AI writes in can fill up with plausible filler if you let it. Three habits keep it sharp. First, save conclusions, not transcripts — ask for the distilled version before you save. Second, file by project, not by assistant: a recipe belongs in Recipes whether ChatGPT or Claude wrote it, which is the same principle as organising notes by project. Third, title like a future searcher. “Mushroom risotto — weeknight version” will be found; “Recipe ideas” will not.
Review occasionally, the way you would any inbox. Unfiled is a fine temporary home for a quick save, but give keepers a project during your next tidy-up. A five-minute weekly review with your notes is enough to stop the shelf becoming a drawer.
Privacy: the notepad has a lockable drawer
Thoughts keeps projects local unless you choose to sync them, and the connector only reaches synced, unlocked content. That gives you a natural split: connect the projects where AI help is useful — recipes, planning, shared work — and keep a journal or sensitive project local, invisible to any assistant. Read the privacy policy for the exact boundaries, and review access any time from Connected apps.
One caution for shared projects: anything your AI saves there is visible to members. Ask it to save rough workings to a private project, and move the polished version across yourself.
Start this week
Connect one assistant. Save three things you would otherwise lose: one recipe, one list, one decision. Open Thoughts on your phone and find each one by searching a word you remember. That small loop — ask, distil, save, find — is the entire system. Everything else in this blog is a variation on it, starting with how to save a whole conversation as a reusable note.
Frequently asked questions
What does it mean to use Thoughts as a notepad for ChatGPT?
Once connected with MCP, ChatGPT or Claude can save a finished answer as a thought in a Thoughts project when you ask, and later search and reread what was saved. Your notes live in Thoughts on your iPhone instead of being buried in chat history.
Does the AI save things automatically?
No. The assistant only creates a thought or project when you ask it to in the conversation. Reading your notes never saves or changes anything.
Which assistants can write to the same notepad?
ChatGPT and Claude both connect to the same Thoughts MCP server, so both write to — and read from — the same synced library of projects and thoughts.
Are notes I keep private visible to the AI?
No. Local-only projects and locked thoughts are not available through the connector. Only cloud-synced, unlocked content you own or have been shared into can be read.
