How is this different from AudioPen or a voice-notes app?

AudioPen turns a ramble into clean text — and stops there. Clean text is still your first, half-formed take. Thought Spark keeps going: it interviews you to develop the spark into an actual angle, keeps your ideas organized by theme, and helps you decide what to publish next.

Can it help when I'm out of content ideas?

The goal is that you're never starting from zero. By catching sparks the moment they strike — on walks, in the shower, mid-conversation — you build a living bank of raw ideas, and Clarify helps turn any one of them into a publishable angle on a blank-page day.

Is it free for creators?

Capturing ideas is always free and unlimited. Pro unlocks unlimited Clarify, which is where a raw spark becomes a developed angle.

For writers & creators

The best hook you had this week is already gone.

Q: I write, I don't talk. Does voice matter?

You can type every capture if you prefer. But the best ideas rarely arrive at a keyboard — voice exists so you can catch the hook hands-free, on the move, before it evaporates. You do the writing later, at the desk, with the spark safely saved.

It arrived on a walk, fully formed, and you told yourself you'd remember it. You didn't. For people whose work is ideas, that's not a small loss — it's the piece you didn't publish. Thought Spark catches the spark by voice in one tap, then helps you sharpen it into an angle worth writing.

Your ideas don't keep desk hours

The cruel thing about a creative idea is its timing: it shows up mid-shower, mid-commute, mid-conversation — anywhere except sitting in front of a blank doc ready to write. And it has a half-life of about a minute. Every hook you lose is a piece you'll never make, and every "I'll remember it" is a small bet you keep losing. The fix isn't more discipline; it's making capture faster than forgetting.

Spark to published, the way you actually work

Catch the hook

Walking the dog, a line lands. One tap, say it — no unlocking, no folder, no title. It's saved and transcribed before it fades.

Develop the angle

Later, at the desk, Clarify interviews the spark: who's it for, what's the sharp claim, what's the one example. Now it's an angle, not a fragment.

Check the take (optional)

Research pulls context and prior takes with sources, so your piece adds something instead of echoing what's out there.

Put it on the calendar

Act turns "write the intro, Thursday 9am" into a real block, so the angle becomes a draft instead of another saved note.

The step that matters most for you: Clarify

A voice-note app hands your ramble back as tidy text. Tidy, but still vague — the same half-formed thought in nicer sentences. Clarify does the opposite: it asks you the questions a sharp editor would, and pulls the actual angle out of the fog.

You captured: "something about how nobody finishes side projects." What do you believe about it that most people don't?

That it's not a motivation problem. People quit at the boring 80%, not the exciting start.

Sharp. Who most needs to hear that, and what's one concrete example you've lived?

Makers on their fifth abandoned repo. Me — I've shipped 2 of 11. The 9 all died at "now do the unglamorous part."

There's your piece: "Side projects don't die at the start — they die at 80%." Want a working title and three section beats?

You walked in with a mushy theme and walked out with a title, a thesis, and a personal example — the hard part of writing, done before you opened the doc.

Fair questions

How is this different from AudioPen?

AudioPen is genuinely good at one move — ramble in, clean text out — and then it stops. Clean text is still your first take. Thought Spark keeps going: it develops the spark into an angle, keeps ideas grouped by theme, and helps you pick what to publish. See the full AudioPen comparison.

Can it help on a blank-page day?

That's the whole idea — you should never start from zero. Catch sparks as they strike and you build a living bank of raw material; on a dry day, open the notebook, pick one, and let Clarify turn it into an angle.

I write, I don't talk. Does voice matter?

Type every capture if you like — it's fully supported. But your best hooks rarely arrive at a keyboard. Voice is there so you can catch them hands-free, on the move; the writing still happens later, at the desk, with the spark saved.

Are my ideas private?

Yes — ideas stay on your device, sent for AI processing only when you run a feature, never used to train models. See the privacy policy.
