The 3am problem.
Late-night ideas arrive at the worst possible moment: half-asleep, in the dark, with no good way to capture them. Reach for your phone and you've lost an hour to a screen. Don't reach for it, and you've lost the idea by morning.
Either way, something disappears.
Frictionless Voice Capture

Three Principles
One button. Press, speak, done. No screens to unlock, no apps to open, no friction between the thought and the record.
Every thought is automatically sorted into an idea, task, or note — with a headline, keywords, and a timestamp — and sent straight to where you already work.
No screen, no notifications, no scrolling. The Thought Catcher exists to be useful for two seconds, then disappear.
The Whole Interaction.
Press. Speak. Sleep.
The Thought Catcher is a screenless, one-button voice device built around a single idea: capturing a late-night thought should take less effort than reaching for your phone. Here's the full interaction, start to finish.
01 - Press
One button. No app to open, no screen to unlock, no phone involved. A single press starts the voice recording instantly, even half-asleep, in the dark.
02 - Speak
Say whatever's on your mind, however it comes out. The Thought Catcher captures your voice using offline transcription (powered by whisper.cpp), so your thoughts stay private and the device works without internet.
03 - Beep, then sleep
A short confirmation tone tells you the thought is safely captured. No screen to check, no app to confirm. Your part is done — go back to sleep.
04 - Wake up to it organised
By morning, your voice note is automatically transcribed, summarised, and sorted into an idea, task, or note — with a headline, keywords, and timestamp — and synced straight into Notion (with Obsidian, Apple Notes, and other integrations coming soon).
How I Design.
The Thought Catcher follows three principles I return to in everything I build. They shape every decision — from the shape of the device to the sound of the beep.
Problems first.
1
Technology does the heavy lifting.
2
Interaction is the product.
3
The best products fix real friction, not invented ones. I start with something genuinely broken in daily life — a lost idea, a wasted minute, a small annoyance — and design from there.
I go deep into AI, hardware, electronics, and software. Real simplicity for the user almost always needs real complexity underneath.
A button. A sound. A moment. I obsess over how something is used, because how it feels matters more than what it does.
