How it works
Four steps, and you start every one of them. The thought you began with is still there at the end of it.
Nothing here needs AI. Even the questions in step 02 are worked out by the app itself, from what your note already covers, with no model involved and nothing sent anywhere. Your thinking leads, and Pro adds optional assistance inside these steps, at the moments you ask for it.
You just watched the first. The other four each get a page of their own, so none of them is a paragraph you have to take on trust.
What stays connected
One sentence, typed badly at a red light, followed the whole way through.
01 · what you wrote
Original note, unchanged
ok so the idea keeps coming back, weekend ceramics workshops in the old mill space. worried about kiln access. maybe 4 sessions before autumn?
Saved exactly as you typed it. Nothing you do later rewrites this.
02 · what you picked
Highlight a line, give it a type.
You choose which parts are worth developing. Ten types, from Goal and Problem to Risk and Next Step.
03 · what it became
The section keeps the exact span it came from, and hovering it in Shape lights that line up in your note.
04 · where it ends up
Export it as Markdown and your original note is quoted at the top of the file, above everything you built from it.
A notes app
Capture → store → find later
The words are kept. What to do with them is still entirely your problem.
A prompt box
Prompt → generate → output
A document arrives fast, and which part of it started as your thinking is anyone's guess.
ideaboxd
Capture → choose → develop → plan
You drive each step, and every piece of the plan keeps a link back to the line it came from.
Why it is different
Capturing the thought is the easy half. This is the other one.
Nothing to name, file or tag at the moment you write. Built as a brainstorming app for one messy head, so the thought goes down in the shape it arrived in.
Nothing is promoted, tidied or summarised on your behalf. You highlight the lines with something in them and develop those into a plan yourself.
Answers you write later sit beside your first note, never inside it. The thought that made the idea interesting is still readable months on.
A promoted line keeps the span it came from, says so on the card, and lights that line up in your note when you hover it.
All four are yours, and none of them needs a model. Pro users can also ask an AI assistant for questions or draft answers at any point, and keep, edit or discard whatever comes back. Your thinking leads. AI helps when you ask.

Ratings
The praise and the criticism, in the words people wrote them in.
Starting as a guest is genuinely fast. I reached the idea dashboard without an email address, password, or payment screen.
The promise “Dump it now. Plan it later.” immediately explains what the product is for, and the examples make the difference from a normal notes app easy to understand.
The landing page was in English, but the guest app opened in Dutch. That language switch felt unexpected and made the transition into the product less seamless.
When I tapped the capture prompt, several polished example ideas appeared immediately. They were useful demonstrations, but I was briefly unsure whether they were sample content or ideas already stored in my account.
The five-step tour explains the workflow clearly, but it delays the first real capture. I wanted to type an idea first and learn the rest when I needed it.
Keeping the original note untouched while turning parts of it into goals, risks, questions, and next steps feels trustworthy. I can structure the idea without losing the thinking that produced it.
The landing page presents five export formats as a key benefit, but guest mode asked me to create an account before exporting. That limitation should be stated earlier so the final step does not feel like a surprise.
