Autocomplete for Mac,
in every app.
FlowIn predicts your next words and shows them as grey ghost text at your cursor. Take a word of it, or the whole sentence. It works in Mail, Slack, Notion, your IDE, and almost anywhere else you type on macOS, and it can run entirely on your Mac.
Free to download. Apple Silicon, macOS 13.3 or later.
See it finish a sentence
Most Mac autocomplete stops at one app
Search for autocomplete on a Mac and you mostly find three things: Terminal completing file paths when you hit Tab, a browser extension that only fills in the box it was installed for, and the suggestions built into one particular editor.
None of them help when you are answering an email, writing a Slack message, or leaving a comment in a document. FlowIn sits underneath all of them instead, as one prediction layer for the whole system.
How it works
Type anywhere
FlowIn watches the field you are writing in and reads the surrounding context, whether that is a reply in Mail or a comment in Notion.
Read the ghost text
The predicted continuation appears inline in grey, ahead of your cursor. Nothing is inserted until you ask for it.
Take what you want
Accept the suggestion a word at a time, or take the whole sentence at once. Carry on typing and it gets out of the way.
Where it works
If your cursor blinks in it, FlowIn types in it. A few of the places people use it most:
- Gmail
- Slack
- Notion
- Messages
- Discord
- Telegram
- Google Docs
- Obsidian
- Chrome
- Safari
- Arc
- Cursor
- VS Code
- Terminal
- ChatGPT
Your text can stay on your Mac
Autocomplete only earns a place in your email and your messages if you trust where the words go. FlowIn ships a local model that runs on your own hardware, so with it selected nothing you type is sent anywhere.
Cloud models are available when you want stronger suggestions. They process the text needed to answer and do not retain it unless you opt in. The full detail is in the privacy policy.
Questions
- Is there an autocomplete that works in every Mac app?
- Yes. FlowIn runs as a system-wide layer rather than a browser extension or a single editor plugin, so it suggests text in Mail, Slack, Notion, Messages, your IDE, and almost any other text field on macOS.
- Does macOS have built-in autocomplete?
- Only in narrow places. macOS has spelling autocorrect and text replacement, and Terminal completes file paths with Tab. Neither predicts the next words of a sentence, which is what FlowIn adds.
- Is FlowIn free?
- FlowIn is free to download and comes with a 14-day unlimited trial. After the trial the free plan continues with 150 autocomplete words and 10 AI replies a day. Pro removes the limits for $14/month, or $10/month billed annually.
- Does Mac autocomplete work offline?
- Yes, if you choose the local model. It runs entirely on your Mac and your text never leaves the device. Cloud models are optional and produce higher-quality suggestions.
- How do I accept a suggestion?
- Suggestions appear as grey ghost text at your cursor. Take one word at a time, or accept the whole sentence at once. Keep typing and it goes away.
- Which Macs are supported?
- Apple Silicon Macs running macOS 13.3 or later. Intel Macs are not supported. Windows is on the roadmap.
