Prelto

Speech recognition starts the moment you hold Right Option and stops when you release. The text appears at the cursor in whatever field has focus, from Mail to Slack to a code editor. Because the model runs locally, a sentence typed this way never leaves your Mac unless you turn on AI cleanup.

When you press the key, Prelto captures only what you were looking at: the selected text, the frontmost app and window title, the browser address, and a screenshot if the selection isn't enough. You can switch the screenshot off. Context is never recorded in the background, which matters if you work with sensitive tabs open all day.

The on-screen AI assistant answers questions about the email, the error dialog, or the document in front of you. Think of the Mac AI assistant as a second pair of eyes on the current window. Answers stream into a small panel instead of a full chat window. Explain, summarize, translate, and debug all use the same gesture, so there's no prompt library to memorize.

Say what you want the reply to accomplish, and Prelto writes a draft, shows it in a review card, and waits. Nothing is inserted until you press Enter. That extra confirmation step is the difference between a useful AI writing assistant and an app that quietly puts wrong words in a client email.

Snippets store the strings you retype constantly: mailing address, Calendly link, intro blurb, signature, out-of-office note, LinkedIn URL. Say the name of the snippet and the full text drops in. It's a small feature that saves more keystrokes than most people expect.

Dictation runs on a local model, and the app keeps a history of up to 100 entries for 30 days on your disk, which you can clear or disable. Ask and AI cleanup go to the provider you connected, billed at that provider's rates. Keys live in Keychain, and OpenRouter keys can be revoked from your OpenRouter account at any time.
