Use Cases

Fluent is an AI assistant that works inside the apps you already use. Press ⌥Space over any app, say what you need, and put the result back where you were working.

These are the jobs people hand it most. Each has a short video, the steps, and prompts to copy. New to Fluent? Start with Write, Reply and Summarize: they need no setup.

Write

Fix what you wrote without leaving the app you wrote it in: an email, a chat message, a document, a post.

1. Select the text.
2. Press ⌥Space and click Fix Grammar. The corrections are marked, so you see what changed.
3. Press ⌘↩, or click Insert in the panel's footer. The corrected text replaces your selection.

The same row has Translate, Magic Refine, Make Concise, Paraphrase Text and Continue Writing. Or say what you want in your own words: select the text, press ⌥Space, type the instruction and press ⌘↩. The result goes straight into your text.

Every action can have a shortcut of its own: select text and press ⌃⌘G for Fix Grammar. Turn on Auto insert for an action, and its shortcut replaces your selection without opening the Smart Panel. See Actions.

Reply

Say what the answer is, and Fluent writes the reply. It reads the conversation you have open, so the draft fits what was asked.

1. Start your reply in the mail or chat app, so the caret is where the text should go.
2. Press ⌥Space, then ⌘\` to attach what you're looking at.
3. Type the gist: "Reply that Thursday at 2 works and the whiteboard is enough. Ask for the agenda. Keep it short."
4. Press ⌘↩, or click Insert, to put the draft into your reply.

This works in Mail, Messages and in webmail or chat in your browser: Fluent reads Mail's whole conversation, a chat's open thread, or the page.

More to try:

• "Decline politely and suggest next week instead"
• "Answer her three questions in order. I don't know the third yet"
• "Reply in Spanish, keep it short"
• "First tell me what he's actually asking for"

To skip ⌘\`, turn on Automatically attach active app and Automatically attach active tab in Settings → Context. See Context.

Summarize

Get the point of something long without reading all of it: an article, a report, a contract, a long thread.

1. With the page open, press ⌥Space, then ⌘\` to attach it.
2. Ask for the shape you need: "Summarize in 3 bullets, under 10 words each." Or click Summarize for a fuller summary with its structure.

Fluent reads the tab in front, a PDF open in your browser, the window of the app you're in, a file you drop on the Smart Panel, a screenshot, or several of these at once.

Type / in the prompt to find these actions.

Compare

Attach several tabs, files or apps to one prompt, and Fluent reads them together. Use it whenever the answer is spread over a few pages.

1. Open the pages you're choosing between.
2. Press ⌥Space, type @ and pick each tab.
3. Ask for a decision, and say how long: "Which one for a team of five? Monthly cost of each, then your pick. Under 45 words."

Ask for a pick and the reason. Without it, you may get a fair table and no answer.

Research

When your open tabs don't have the answer, Fluent searches the web, reads what it finds and answers with its sources.

1. Press ⌥Space. For a longer session, press ⌘E to move to the chat window.
2. Type @plan and press Return to add Plan: Fluent splits the question into steps that search at the same time.
3. Ask, and say what you want back: "Kindle Paperwhite (2024) or Kobo Clara BW for reading at night? Small table: screen, battery, weight. Then a one-line verdict."
4. Click a source to check it, and ask follow-ups in the same chat.

Fluent plans on its own when a request has several parts; with Plan it always does. A plain question needs neither: just ask.

More to try:

• On a product page, with the tab attached: "What do owners complain about most with this model?"
• On a sentence you selected: Check a Claim
• "Find three quiet hotels near Lisbon's Alfama. Show me pictures of each"
• "What's new in the latest macOS update? Only what changes how I work"

When the answer matters, ask a Council in the chat window: several models answer, review each other's answers, and one writes the final verdict.

Learn

Understand something faster, then check that it stuck.

1. On the page or PDF you're studying, press ⌥Space, then ⌘\`.
2. Ask "Quiz me on this, one question at a time. Three choices, be brief."
3. Click an answer. Fluent says whether it's right, explains why, and asks the next one.

More to try:

• Select a hard paragraph and press ⌃⌘V: Explain Like I'm 5 puts it in plain words
• "What are the three things to remember from this chapter?"
• Make Study Cards turns your material into questions and answers
• Interactive Language Tutor talks with you in the language you're learning and corrects you as you go

Dictate

Talk instead of typing, in any app. Turn on Settings → Voice → Enable voice dictation once, then:

• In a text field, press ⌃⌥Space and speak. Your words appear as you talk, cleaned up on your Mac. Press it again to stop.
• Anywhere else, the same shortcut asks Fluent. "What's on my calendar tomorrow?" "This page in three bullets."

Say "new paragraph" for a blank line, and end with "press return" to send a message hands-free. See Voice.

Organize

Fluent doesn't only tell you how to tidy up: it does it. It works with your files, calendar, reminders and notes.

1. Open the folder in Finder and press ⌥Space.
2. Ask: "Sort this folder into invoices, screenshots and installers. Reply in one line."
3. Look in Finder: every file is in its folder.

Out of the box, Fluent asks before it edits, moves or deletes a file: click Approve on the badge, or press ⌘A. In the video it moves files without asking. To allow that, click Finder in Settings → Integrations and untick Ask Before Running for its move tools.

macOS asks for access to Calendar, Reminders or a folder the first time. See Built-in Integrations.

Delegate

Where no integration reaches, Fluent works in the app itself. With Computer Use it reads the app's window, then clicks and types with a pointer of its own, while your mouse and keyboard stay yours.

1. Attach what it should work from, such as a receipt.
2. Ask, and name the app: "Add this receipt to Expenses as a draft for the Lisbon offsite."

More to try:

• "Fill in the shipping form in Safari with my address from Memory"
• "Copy the totals from this PDF into the open Numbers sheet"
• "In Music, find Kind of Blue and play it"

See Computer Use.

Automate

Anything you ask for twice can be an action with its own shortcut. Anything you want regularly can run on a schedule, even while your Mac sleeps.

1. Ask in any chat: "Every weekday at 8:30, brief me on my day: weather, meetings and anything urgent. Wake my Mac if it sleeps."
2. Fluent creates the action, schedules it, turns on Wake Mac to run and tells you what it set up.
3. Leave your Mac on its charger and close the lid. The briefing is waiting when you open it.

Start small. "Summarize my morning news sources" is a better first automation than "run my whole day". See Actions.

Remember

Tell Fluent something once and it uses it from then on: facts about you, your product's rules, how you sign your emails. Memory is stored on your Mac.

1. Tell it: "Remember: we refund in full within 30 days, and I sign support emails as Alex from Kestrel."
2. In any later chat (in the video, a new tab: click + or press ⌘T), attach a customer's email with ⌘\` and ask "Reply in two sentences, signed." The draft has the policy and your signature.
3. Press ⌘↩, or click Insert, to put it into your reply.

Go further:

• Add product docs, past replies or a folder of notes in Settings → Memory, and answers are grounded in them.
• Put samples of your own writing into My Writing, then ask "reply the way I would".
• "Forget my gym schedule" removes a detail. Settings → Memory shows everything Fluent keeps.

See Memory.

Keep Going

Fluent works with the AI you already have: your own API key, your Claude, ChatGPT, Google AI or GitHub Copilot subscription, or a model that runs on your Mac and never leaves it. See Models & Providers.
