Strata for macOS · System-wide AI

Your AI, anywhere on your Mac.

Select text in any app. Press ⌘⌥E. Strata rewrites it in place — no tab, no paste, no lost thread.

New Chat

A close-up portrait of a tabby cat with amber eyes — editorial style, shot on a Canon R5, 85mm f/1.4, golden-hour rim light. Composition: rule of thirds, shallow depth of field, warm bokeh background. Mood: calm and premium — like a print ad for a camera brand. Output: 3:2, ultra-detailed fur texture, natural color grade.

§ Strata · 01 The problem

The tool is always in another tab.

The AI is genuinely good now. That was never the issue. The issue is where it lives. It sits in a browser tab, behind a login, in a window that isn't the one you're working in. You're mid-sentence in an email. You stop, switch windows, and re-type the context you just walked away from. You paste, you wait, you copy the answer back, you fix the formatting. Then twenty minutes later you do the whole thing again. None of it is hard. It just never stops.

The loop you already know

  1. Leave the app you’re in
  2. Re-explain the context
  3. Paste the text
  4. Wait for the answer
  5. Copy it back, fix formatting
  6. Find your place again

Six steps to do one small thing — and the AI was supposed to be the shortcut.

§ Strata · 02 What that costs

The cost isn't the seconds. It's the thread.

A context-switch is cheap to measure and expensive to live. The few seconds aren't the damage — the broken focus is.

Each detour is small. You take dozens a day. Together, they're the work.

And it compounds. A tab for writing. A tab for code. A tab for translation. A tab for summaries. Each one promised to save you time, and each one lives somewhere that isn't where your cursor is. The intelligence is everywhere — just never in the document you're actually in.

You don't feel one switch. You feel the end of the day, when the deep work never happened because it kept getting interrupted by the tool that was meant to help.
§ Strata · 03 The turn

What if the tool came to the text?

No new window. No tab to return from. No context to re-explain. The AI stops living somewhere else — and shows up exactly where you already are.

One keypress, in place Select the text. Press ⌘⌥E.

Strata runs your AI on the selection and writes the result back exactly where your cursor sits — inside Mail, Slack, Notes, VS Code, Safari, Arc. The window you would have opened never opens. The loop above never starts. The thought you were holding stays whole.

Translation explanation. TIP · CLICK OUTSIDE THIS WINDOW TO CLOSE

  1. Tone — "chắc chắn rồi" is casual assurance → "Sure thing" keeps the friendly register.
  2. Tense — "sẽ gửi ... tối nay" → English future "I'll send it over tonight".

§ Strata · 04 Modes

One keypress. Any job. You decide what it means.

The shortcut never changes. What it does is a mode — a saved system prompt you write once. Name a mode, pick a provider and model, describe what it should do. That mode is now one keypress away in every app. Browse ready-made ones in the community Mode Library, or build your own.

A mode is a saved prompt Write the behavior once. Trigger it anywhere.

§ Strata · 08 FAQ

The doubts before you switch.

01Does it really work in every app?

In the apps where you do most of your writing, yes — Mail, Slack, Notes, VS Code, Safari, Arc. Strata reaches into the text field and replaces your selection where it sits.

02What about apps that block inline edits?

A few apps lock their text fields. There, the Enhance Me panel opens with ⌘⇧E instead. You paste or drag the text in, run your mode, and copy the result back in one move.

03Isn't this just autocomplete or Grammarly?

No. Autocomplete guesses your next words; Grammarly enforces standard English. Strata does whatever the mode says — one shortcut that carries any behavior you define, to wherever your cursor already is.

04Where do my text and API keys go?

Custom provider keys live in the macOS Keychain and requests go straight to your provider — your keys never touch our servers. Built-in modes route through Strata's backend only to run your request; nothing is stored for training. Local settings. Transient AI requests. No workspace sync.

05Do I need an account?

One email, one-time code — no password to create or leak. Your plan and included monthly requests follow your account.

06Is Strata on iPhone?

Yes — Strata for iPhone puts Correct Me, Enhance Prompt, and Translate inside your keyboard, with English and Vietnamese Telex typing. Free on the App Store.
