Nextline puts the rest of your sentence ahead of your cursor, in grey, as you type. Press Tab to accept the next word — or the whole line. Keep typing and it gets out of the way. That's the entire interface.
If you know the Tab key in Cursor or Copilot: it's that, for everything you write on your Mac. Emails, messages, and documents get finished up to 2× faster.
No plugin list, no "supported apps" table. Nextline completes text in practically any macOS text field — Mail, Messages, Slack, Notion, Safari, Gmail, even your ChatGPT and Claude prompts. If you can type in it, Nextline can finish the line.
Nextline runs a local LLM on your Mac. Your text never leaves the machine, and everything works with the internet off. There's no microphone involved either — it's autocomplete, not dictation — so it works in an open-plan office, on a call, or next to someone asleep, without you saying a word.
No trial, no word caps. Download it, open anything with a text field, and press Tab.
