The text you want in Mail is not the same text you want in Slack, Notion, Cursor or Codex. Per-app rules make dictation more practical by choosing the right mode automatically, so you do not have to stop and think about settings every time the context changes.
Many dictation tools treat all text the same. You do not. You write differently in email than in chat, and differently to Codex than to a customer.
Per-app rules make that difference part of the workflow. When you switch apps, Vara can switch mode with you.
Same voice, different output
You should not need to change how you speak for every app. You speak naturally, while Vara uses context to decide whether the output should be short, professional, raw or prompt-like.
The outcome is less friction between workspaces.
A realistic setup
Mail: professional mode for calm, sendable replies.
Slack or Teams: clean text, shorter and more natural.
Notion or Obsidian: raw or clean notes depending on the job.
Cursor, Codex or Claude Code: VibeCode for agent prompts.
Where it saves time
The time saving is not only the dictation itself. It is avoiding micro-decisions: which mode, which tone, which cleanup.
That matters most for people who switch between many kinds of text during the day.
How Vara does it
In Vara you can attach a mode to a specific app, so it switches automatically. You can still override when needed.
Small feature, large daily effect: fewer menus, fewer stops, less context switching.
