A brain dump tool takes everything swirling in your head, splits it into separate ideas, and files each one where it belongs: your to-do app, your content list, your someday pile. I built mine with Claude Code so I can talk into my phone and trust every idea landed somewhere. This post walks through how mine works, what broke along the way, and gives you a free generator that writes your own version in about two minutes.

The head that would not shut up
I built more than 30 tools, workflows, and posts in August. I’m not saying this to brag, I’m saying it to explain the problem it created. Every one of those projects left ideas behind, and new ones kept arriving on top: apps, blog posts, social stuff, house things, all of it running through my head all day and night. It got maddening. I’d sit down to work and spend the first twenty minutes remembering everything instead of doing anything.
So two days ago I built the thing I’d been putting off since July: a brain dump tool. I talk at it, and it takes the mess from there. Fair warning, I’m excited and this is a first report, not a six-month retrospective. But so far, so good, and the design is solid enough to share.
The relief showed up before I did anything about a single idea. They were out of my head and sitting somewhere I’d actually look, and even if I never act on half of them, they’re not circling my brain at 2am anymore.
What does a brain dump tool do?
A brain dump tool listens to an unsorted ramble and turns it into filed, findable ideas. Mine does three things in order: it splits my ramble into separate items, it keeps my exact words for each one, and it routes every item to a real place I already check. A task for me goes to Asana. A task for my automations goes to my work queue. A blog idea goes to my content backlog. Then it hands me the one easiest item with a tiny first step, in case I want to start something.
The routing is the part that matters. I’ve kept notes apps before, and they turn into a second mess you now have to sort. Here’s the difference in practice:
| Where the ramble goes | What you end up with |
|---|---|
| A notes app | One long page of mixed-up ideas you have to sort later (you won’t) |
| A task manager | Every idea becomes a task, including the ones that were never tasks |
| A brain dump tool that routes | Each idea lands in the place you already check for that kind of thing |
The tool picks the destination. I don’t sort anything. As long as every idea goes somewhere, I’m happy, and I can always sort further later.
Who is a brain dump tool for?
It’s for people juggling a bunch of unrelated things at once. My head holds a blog post, an app bug, a side hustle idea, and a reminder about the dogs in the same five minutes, and no single system catches all four. If your ideas span work, content, home, and three hobbies, a sorter that routes each one to its own home earns its place fast.
It’s not for everyone, and I’d rather say so than waste your afternoon. Skip it if:
- You work on one project. You don’t have a routing problem. A plain to-do list beats this.
- You want a task manager. This isn’t one and doesn’t replace one. It feeds the systems you already have.
- Your ideas already have one obvious home. If everything you think of belongs in the same notebook, keep the notebook.
If the pile is more feelings than tasks, I wrote the gentler version of this over on my other blog: sort them into seeds.
What do you need to build a brain dump tool?
Less than mine took. My version is wired into my own dashboards, but the generator below builds you a version that needs almost nothing:
- An AI chat you already use (Claude or ChatGPT). This is the sorter. The prompt version works in the free tier of either.
- Claude Code if you want the skill version, which remembers your setup so you never re-explain it. This is the route I’d pick if you already use it.
- The places you already check. Your to-do app, your notes, your content list. You’re not signing up for anything new. The tool routes to what you have.
- Your phone’s keyboard mic if you want to talk instead of type. No extra app.
For the curious, my version runs as a page on my private dashboard: a Cloudflare Worker calls Claude to do the sorting, an Airtable table remembers every idea I’ve ever dumped, and Asana catches the tasks. None of that is required to get the core loop working. The sorting brain is a prompt, and prompts are portable.
How does a brain dump tool work?
Mine works in four steps: I talk or type a mess, Claude splits it into items and keeps my exact words, each item gets matched against a list of everything I’m working on, and then everything files itself. The matching step is what makes it feel smart. My tool holds an index of 490 things I’ve built or written, so “I should fix the sorting on that reselling page” resolves to the actual page, not a vague note.
That index is also where the build almost went wrong. The first version matched on shared words and confidently pointed me at the wrong file, twice in one test. A wrong path is worse than no path, because it burns the exact time the tool exists to save. The fix was making it humble: if two things look plausible, it asks me instead of guessing, and it never invents a match. My tool asks more questions now, and I trust it more, not less.
Two other things broke, since this blog has a whole category for that. The microphone refused to work on day one with no permission prompt at all, and the culprit was me: my own security settings block the mic on every page by default, so I had to let this one page opt in. And the original design made me confirm where each idea went with a tap per item. The taps failed silently at first, and while fixing them I realized I didn’t want them at all. Now everything auto-files the moment it’s sorted, with an undo link per item. Sorting by hand was the exact chore I built this to delete.
The last step borrows from my done log: after filing, the tool offers me the single easiest item with a first step small enough to feel silly. One thing, not a plan or a schedule, in case the dump left me wanting to start.
That tiny first step exists because of a pattern I know too well, knowing the next step and still not starting.
The best part came free with the phone. I added the tool to my home screen, and I’ll admit I didn’t know how easy that was until this week. Now I ramble from the couch, from the kitchen, wherever the idea hits, and my desk is no longer where thoughts have to wait in line.
Get the skill
The generator below builds your version. It asks what fills your head, where each kind of idea should go, whether you want the easiest-thing starting point, and what you’ll say to trigger it. Then it writes two things: a skill for Claude Code, and a prompt you can paste into any AI chat. Same sorter, two formats.
Two things to make it yours. First, the places list is the whole tool, so use real destinations you already check, not aspirational ones. “Blog ideas go to my content spreadsheet” only works if you actually open that spreadsheet. Second, pick a trigger word you’ll say naturally. Mine is braindump, one word, because that’s what my brain calls it.
If you go the skill route, paste the output into Claude Code and tell it to save the skill. It writes the file for you. I customize every skill I use this way, and I wrote up why in I don’t install Claude Code skills, I customize them.
What it doesn’t do
No streaks, no reminders, no guilt. If I park an idea, the tool moves on without a sad face. It does keep count of how often I’ve mentioned something, so a thought I’ve dumped four times becomes visible as a pattern, but visibility is the whole intervention. Nagging me was never on the feature list.
It doesn’t replace a task manager, a calendar, or a content plan. It feeds them. The day it starts growing its own lists is the day it becomes another inbox, and I have enough of those.
And the rough edges: my index of projects refreshes manually, so brand-new builds are invisible to it until I update the list. The asking-instead-of-guessing rule means a vague dump can come back with two or three questions, which is the right trade but not a magical one. And it’s two days old. I’m telling you what I designed and what’s held up so far, not what survived a year. Ask me in six months.
Frequently asked questions
Is a brain dump tool the same as a to-do list app?
No. A to-do app stores tasks you type into it, already sorted, already phrased as tasks. A brain dump tool accepts a raw unsorted ramble, splits it apart, and routes each piece to the right system, which can include your to-do app. It sits in front of your other tools, not instead of them.
Can I build a brain dump tool without knowing how to code?
Yes. The core of the tool is a set of written instructions for an AI chat, not software. The generator in this post writes those instructions from your answers, and the paste-in prompt version works in a plain Claude or ChatGPT conversation with zero setup.
Does a brain dump tool work with voice?
Yes, and voice is where it shines. On a phone, the keyboard’s mic button turns any chat into a talk-at-it tool. Rambling out loud captures ideas faster than typing and skips the urge to pre-organize, which is the thing you’re trying to stop doing.
How is this different from keeping a notes app?
A notes app stores the mess exactly as messy as you left it, and the sorting becomes a chore you owe your future self. A brain dump tool does the sorting the moment you dump, so each idea lands somewhere specific. The 30 seconds of routing is the difference between captured and handled.
What happens to ideas I never act on?
Nothing, and that’s fine. Mine logs every idea with the date and where it went, so nothing is lost, and repeat ideas get counted instead of re-filed. Some ideas exist to be released, not executed. Getting them out of your head is the win even when no task ever comes of it.
Try it yourself
The short version: a brain dump tool listens to your unsorted ramble, keeps your exact words, and files every idea into a place you already check, so your head can stop holding everything. Build yours with the generator above, dump one real mess into it today, and see how your brain feels afterward. Start with your places list, keep it to places you actually open, and let the tool make the sorting decision you’ve been avoiding.
