ADHD brains don't fail at having good ideas — they fail at the transitions. Recording starts before you forget why you opened the app. Tap, speak, done.
At any moment: a measurement, a feeling, a task, an idea, a reminder. All competing for the same working memory. All equally likely to disappear at the next context switch.
You had the perfect insight mid-task. You switched to Slack for 30 seconds. It's gone. Researchers call this attention residue — the measurable cognitive cost of context switching. It's not you. It's neuroscience.
They all need too much: open, choose a notebook, type, structure, decide. By the time the app loaded, the moment passed. You gave up. Again.
The same idea keeps surfacing because it never got captured. Your brain wastes cycles re-discovering what it already knows.
Open the app. Recording starts in under a second — no buttons, no setup, nothing to figure out. Just open it.
Say what's on your mind. 15–30 seconds. Your voice stays on your device — transcribed locally, never uploaded to a server.
AI cleans it up, adds tags, pulls out any tasks. You're back to work in under 2 seconds. That's the whole app.
Minimum friction path: trigger → speak → stop → done. Three steps. Zero decisions. You never have to think about the tool.
A brief, timestamped note written at every task transition throughout your day.
Coined by productivity coach Tony Stubblebine in 2017, interstitial journaling is deceptively simple: every time you switch contexts — finish a task, take a break, feel stuck, have a thought — you write 1–3 sentences. What just happened. How you feel. What's next.
Dr. Sophie Leroy (University of Washington) demonstrated in 2009 that when you switch tasks, part of your attention stays stuck on the previous one. She called it attention residue. Her research showed that writing down where you are before switching measurably reduces this residue — freeing your brain to fully engage with what's next.
For ADHD brains, the effect is amplified. The practice externalizes working memory, captures fleeting ideas without derailing focus, and timestamps entries to fight time blindness — addressing three core ADHD challenges in a single micro-habit.
Finished the slide deck. Feeling good about the data section. Need to prep talking points before the 10am call.
Slack pulled me into a rabbit hole. Back now. Call in 8 minutes — reviewing my notes quickly.
Good call. One action item: follow up with Mara on the Q2 budget. Switching to deep work on the proposal now.
The #1 reason people abandon interstitial journaling is friction. Opening an app, choosing a format, typing at every transition — it's enough to break the habit. Notchd removes all of it. Tap, speak for 15 seconds, done. The transcription, cleanup, and tagging happen automatically. You never have to think about the tool.
Your voice never leaves your iPhone. Transcription runs locally on-device via Whisper. Only the cleaned text is ever sent to AI — never your audio, ever.
Notchd builds a Personal Dictionary from your corrections. "SparkMES," "Azander," your company's internal terms — it remembers them so you stop repeating yourself.
Every entry is silently tagged with time, location, battery, and network state. No manual logging. The context is just there when you need to search back through it.
Bad signal, airplane mode, basement WiFi — Notchd captures everything offline and processes it when you're back. Nothing is ever lost because you weren't connected.
Tasks extracted from your captures drop into a triage tray. Swipe to mark NOW (today), LATER (queued), or DONE. Your entire to-do list lives inside your journal.
Swipe left before recording: Journal entry — personal, reflective. Swipe right: Note — actionable, findable. The gesture is the decision. No modal ever opens.
