Ten seconds is the whole window
Every other kind of writing has an alternative. You can answer an email later from a laptop, you can draft a document at a desk, you can leave a post until the evening and lose nothing.
A thought does not wait. It arrives while you are driving, cooking, walking out of a meeting, halfway up a ladder, or three minutes into falling asleep. If capturing it takes longer than about ten seconds, you do not capture it, and five minutes later it is gone entirely.
That makes notes a race against a very short clock, and dictation is the only input method that wins it. Speaking a sentence takes four seconds. Typing the same sentence with one hand while holding something in the other takes thirty, if it happens at all.
Accuracy counts for less here than in any other use of dictation. You will read the note within a day, you wrote it, and you can follow your own shorthand even with three words misheard. What kills note taking is friction at the moment the thought turns up.
Count the taps you make now
Count them honestly, for whatever you use at the moment. Unlock, find the app, wait for it to open, create a new note, find the microphone, wait for it to be ready, speak, wait, copy the result, paste it somewhere useful. Every one of those is a place where the thought escapes or you decide it was not important enough.
A keyboard with a microphone key collapses most of that. Open whatever note app you already use, tap the field, tap the microphone, speak. The words arrive where your cursor is, and there is nothing to copy afterwards.
That last part is the quiet advantage a keyboard has over a dedicated transcription app. Your notes stay in whatever you already use. Nothing is duplicated into a second place, nothing needs syncing between a transcription tool and your real note app, and no separate pile of half-finished dictations builds up to be reconciled later.
The note then inherits whatever your note app does with it, and that is a thing to check once. The keyboard's job ends when the text lands in the field.
Where it turns clumsy: the shopping list
Dictating a shopping list works if you say it as a sentence and tidy it later. Most systems infer punctuation from the rhythm of your speech, and a pause does not create a bullet. You get a paragraph, not a list.
If you want a real list, dictate the items and format afterwards, or speak several short notes instead of one long one. This is one of the few places where typing genuinely competes, because a list is mostly short nouns, and a short noun standing on its own is exactly what dictation handles worst. There are no surrounding words to steer it.
Door codes, flight numbers and the digits off the back of a card belong in the same category. Checking them afterwards takes longer than tapping them in would have.
Say who, say what, say when
Spoken notes come out terse, because you are in a hurry and the meaning is obvious to you right now. A week later "call about the thing on Thursday" is meaningless.
Two extra seconds of context fixes it: who, what, why. "Call Marieke about the roof quote, she said Thursday." You will not regret the extra words and you will absolutely regret their absence.
Small markers that make a note findable later work the same way. Say a consistent word for a category, and later you can search for it. It is a crude system and it works better than any tagging feature you will not remember to use in the moment.
Pick the marker words once and keep them boring. "Shopping", "work", "house", "medical". A word you invent afresh each time is a word you will not think of when you go looking.
The plumber, the street, the medication
Notes are dense with proper nouns: people, streets, shops, products, medication, the name of the plumber. Those are precisely the words a general speech model has never encountered, so it substitutes something ordinary that sounds similar.
If your keyboard lets you add vocabulary, notes are the use case that repays it fastest. LocalType keeps added words on the handset and gives them to the speech model as context, so the names you use repeatedly start arriving correctly instead of needing a correction every time.
Add the recurring ones once: family, colleagues, your street, the town, the things you buy regularly. Ten minutes at the kitchen table covers most of a year's notes.
Car parks, lifts, basements, aeroplanes
The microphone is a key on the keyboard, so capture starts the moment a text field opens, in any note app you like, on phones and tablets running Android 8.0 and newer.
Notes get taken in the worst possible places for a connection, which is why the offline part carries more weight here than in most other uses. Recognition runs on the phone itself, from a model file kept in storage only the app can read, so a basement changes nothing. Internet access is asked for once, to fetch the model you pick, and never again.
Notes are also where the genuinely personal material goes: health, money, things about other people, ideas you have not told anyone. With on-device recognition none of that audio is transmitted. No account is attached to the keyboard. Nothing inside the product does advertising or behavioural tracking, and no archive of your recordings is kept. The app's data is deliberately excluded from Android's cloud backup. In password fields the microphone switches itself off, which matters if you were about to note down a code.
Three model sizes, at 60, 190 and 539 MB, let you decide the trade. For notes the fastest one is often the right choice, because you want the words down and you can fix them later. The middle option needed 4.1 seconds for 6.9 seconds of speech on the 4 GB test handset if you want a sense of the difference. Eighteen languages are covered by one multilingual model, chosen from the recording rather than from a menu.
Read them back once a day
A dictated note is raw material, and treating it as finished is how people conclude the method does not work.
Build in a review. Once a day, or whenever you sit down at a screen, read through what you captured and do three things: fix the names, add the detail you skipped, and act on anything that turned out to be a task and not just a thought.
That pass takes two minutes and it is much easier than it sounds. You are reading your own words from a few hours ago, not deciphering something you scribbled down last month.
Deleting is the other half of the habit. Most captured thoughts turn out to be unimportant once you see them written down, and clearing them out is what keeps the useful ones visible.
