Loose, fast team chat
A casual rule keeps messages short and human — contractions, light punctuation, the odd emoji — so you sound like a colleague, not a press release.
Smart Rules · macOS
Per-app writing rules. The right tone, every app.
Tell Voicr how to write in Slack, in Mail, in your editor — once. It detects the app you're in and applies your rules automatically, so every dictation comes out in the register that app deserves.

One voice. The tone each app needs.
You don't talk to your team the way you write to a client. A Slack message is loose and quick. A client email is measured and polite. A comment in your code editor is terse and technical. Per-app writing rules let Voicr honor that difference for you — automatically, every time you dictate.
Most dictation apps give you one output style, or a fixed three-way toggle you flip by hand. Voicr's Smart Rules are yours to write. You define what "casual" means for Slack, what "formal" means for Mail, what "raw" means for your editor — in plain language, in as much or as little detail as you want.
Then you forget about it. Voicr watches which app holds focus and applies the matching rule the instant you speak. Switch from Slack to Gmail mid-thought and the tone switches with you — no menu, no mode picker, no second-guessing which style is loaded.
How per-app writing rules work
Four steps to set up. Zero steps to use.
- 01
Pick an app
Open Voicr from the menu bar and choose an app you write in often — Slack, Mail, Notion, your code editor, anything you dictate into regularly.
- 02
Write the rule
Describe the tone and format you want in plain English. "Keep it casual, short sentences, emoji fine." "Formal, full punctuation, no contractions." It's your instruction, in your words.
- 03
Let Voicr detect the app
From then on, Voicr knows which app is in front of you. When you dictate, it reads the active app and loads the rule you wrote for it — instantly and locally.
- 04
Dictate anywhere
Speak the way you normally would. The transcript comes back already shaped by the right rule: casual where it should be casual, formal where it should be formal.
What people set rules for
A handful of rules cover most of a working day.
Polished client email
A formal rule adds full sentences, a proper greeting, and a measured tone, turning a quick spoken thought into something you'd happily send a customer.
Structured notes and docs
A structured rule favors clean lines, lists, and headings, so meeting notes and specs come out organized instead of as one long paragraph.
Terse technical comments
A technical rule strips the niceties — no fluff, no rephrasing your variable names — and keeps code comments and commit messages short and literal.
Quick personal replies
A personal rule keeps texts to friends relaxed and lowercase, so a "running late" message never comes out formatted like an office memo.
On-brand public posts
A posting rule holds a consistent voice across everything you publish — confident, concise, and unmistakably yours, whatever the day's mood.
Why Smart Rules beat a tone toggle
Rules you actually write
Not a fixed casual/formal switch. You describe the tone in your own words, with as much nuance as a given app needs.
Automatic app detection
Voicr reads the active app every time you dictate. The right rule loads on its own — you never stop to pick a mode.
Consistent, every time
The same app always gets the same treatment. Your Slack voice and your email voice stay reliably distinct.
Works across all of Voicr
Rules shape dictation, translation, and AI polishing alike — one tone system across every way you put words on screen.
Native and instant
A real macOS menu bar app. App detection and rule loading happen locally, with no lag between speaking and seeing the result.
Free to use
Smart Rules are included on the free Voicr plan, alongside dictation, translation, and every other feature. No credit card.
Per-app writing rules — FAQ
What are per-app writing rules?
They are tone-and-format instructions you attach to specific Mac apps. Voicr detects which app you are writing in and applies the matching rule automatically, so your dictation comes out casual in Slack, formal in Mail, and so on — without you switching anything by hand.
How does Voicr know which app I'm in?
Voicr sees which app currently holds focus on your Mac. The moment you dictate, it checks the active app and loads the rule you wrote for it. If an app has no rule yet, your default writing style is used instead.
Can I write my own rules, or are they preset?
You write them. A rule is a plain-language instruction — "short and casual, emoji OK" or "formal, no contractions, full greeting." You can be as brief or as detailed as you like, and edit any rule whenever your needs change.
Do Smart Rules work with translation and AI polishing?
Yes. A rule shapes the final text whether you dictated in English, translated from another language as you spoke, or had Voicr polish a rough transcript. The tone system is the same across every Voicr feature.
How is this different from built-in context awareness in other apps?
Many dictation apps auto-pick from a small set of fixed styles. Voicr's Smart Rules are written by you — you control exactly what each app's tone means, in your own words, rather than choosing from a short built-in list.
Is Smart Rules free?
Yes. Per-app writing rules are part of the free Voicr plan, which includes 5,000 words a month with no credit card. Every feature is available on the free plan.
