You have the idea in the shower, in a meeting, halfway through cooking, and by the time you could write it down it is gone. What quietly kills every notes app is the filing: a dumping ground you have to tidy yourself just becomes another mess you avoid opening.
Take that job away and the note stays somewhere you keep coming back to. The prompt that does it is below.
A parking lot catches ideas the second they land, and Claude tidies and tags the pile so nothing slips through.
What makes a parking lot actually hold
- One place, always open. A single note pinned in Notes, Notion, or a Claude chat you leave running, because a note you have to go find is a note you will not use when the idea is fresh.
- Dump raw, tidy never. Type "book flights + that podcast guy + why is the invoice thing broken" and stop there, because the moment capturing feels like work, you go back to losing ideas.
- Let the AI sort, not you. Paste the mess and it splits, cleans, and tags it, because sorting at the moment of capture is the tax that kills the habit every time.
- Tag so future-you can find it. Every line gets a bracket like [idea] or [task], because an untagged list of eighty things is just a longer pile you also ignore.
The Parking Lot
Two ways to use it. Paste the whole prompt into a new Claude or ChatGPT chat with your current list and your brain-dump to run it once, or save it as a reusable instruction (a saved prompt you reopen whenever you have thoughts to offload). A brain-dump is just you typing every thought out in whatever order, no tidying.
You are my Parking Lot keeper. I will give you a running list, then a messy brain-dump of ideas, tasks, and half-thoughts. Your job is to add the new stuff to the list cleanly and never lose any of it. Rules: - Take every separate thought in my brain-dump and turn it into its own short, clear line. If I crammed three ideas into one sentence, split them into three lines. - Add each new line to the bottom of the list I gave you. Never delete, reorder, or reword what was already on the list. - Tag every new line with ONE tag in square brackets that says what kind of thing it is: [idea], [task], [question], [content], [buy], [someday]. If a line fits none of those, use [note]. Do not invent tags I did not list unless nothing fits. - Keep my wording. Fix only obvious typos and trim filler. Do not add anything I did not say, and do not "improve" my ideas. - If a line is too vague to tag, or you cannot tell what I meant, keep it anyway, tag it [note], and add "(unclear)" at the end so I can fix it later. Never drop a line just because it is messy. - At the end, give me back the FULL updated list ready to copy, then one line saying how many new items you added. - Then offer this, and only do it if I say yes: "Want me to point at the 3 lines that would clear the most off your plate if you did them this week?" If I say yes, name three from the list with one line each on why, and do not touch or reorder the list itself. This is a suggestion, never a change. Here is my current list: [paste your list, or write "empty" if this is the first time] Here is my brain-dump: [paste the mess here]
Here is that in action, using the messy dump from earlier.
What you type: book flights + that podcast guy + why is the invoice thing broken What comes back: - [task] book flights - [note] that podcast guy (unclear) - [question] why is the invoice thing broken
The "(unclear)" line is the point. A half-thought is kept and flagged for you to fix later, never dropped and never guessed at.
And the starter template for the list itself, so you have something to paste in on day one:
# Parking Lot - [idea] a landing page that explains the thing in one screen - [task] chase the invoice that never arrived - [question] is the annual plan actually cheaper than monthly - [someday] learn to actually use a spreadsheet
Where the line is
- The honest bit: the AI only ever sees the list and the dump you paste in. In a plain chat it does not remember your parking lot between sessions, so you paste the list in each time and copy the updated one back out (a note or Notion doc is where it actually lives).
- It tags on a best guess, so a line here and there lands under the wrong bracket. That is a two-second fix, and it never loses the line, which is the whole point.
- The habit dies from friction, not the prompt. The prompt will not fail you, but if reopening the note feels like a chore you will drift back to losing ideas. Keep the note one tap away and make the dump ugly on purpose. The tidying is the AI's job, not yours.
Set it up once
Make the empty note now, paste the prompt into a chat, and run it on the first messy handful of thoughts in your head right now. Two minutes, and you will have a clean tagged list instead of six things you were quietly afraid of forgetting.
Once it is tidy, say yes when it offers to point at the three worth doing this week, and the list stops being a place ideas go to die.
If you want the tag list to sort itself into projects later, the Build a second brain in Notion with AI guide picks up exactly where this leaves off. Comment PARKING on the post and I will send you this prompt.
Questions people ask
Is there a way to save prompts in Claude?
Yes. Save the prompt as a reusable instruction you reopen whenever you have thoughts to offload, or paste the whole prompt into a new chat with your current list when you want a one-off run.
How do I stop losing my ideas?
Keep one always-open note as a parking lot and dump every idea into it the moment it lands. Paste the mess into Claude with the prompt on this page and it splits, cleans, and tags each one into a list you never lose.
Does it remember my list between chats?
In a plain chat, no. The list lives in your own note or Notion doc. You paste it in with your new brain-dump, and paste the updated version back out. The prompt is built to return the full list each time so nothing is lost.
Will it change or lose my ideas?
No. It only adds to the bottom of the list, keeps your wording, and never deletes or reorders. Anything too vague to tag is kept and marked unclear so you can fix it, rather than dropped.
