Show HN: TypeSeer – on-device autocomplete for every text field on macOS

TypeSeer launched as a system-wide AI autocomplete for macOS that runs a language model directly on Apple Silicon so typed text never leaves the device. The app offers grey-text suggestions in any standard macOS text field, accepts them with the Tab key, supports 15 languages, and is free for 14 days with no account or card required, targeting macOS 14 and later. TypeSeer states it never suggests in password or secure fields and only uses the internet for model downloads, a daily update check, and license verification.

Your Mac finishes your sentences. TypeSeer is a system-wide AI autocomplete for macOS. It suggests the rest of what you’re typing, as grey text right after your cursor, in almost any app. Press Tab to take it, or just keep typing. Free for 14 days · No account, no card · Apple Silicon, macOS 14+ By downloading you accept our Terms terms.html · Acknowledgments and licenses acknowledgments.html Private by design The AI runs on your Mac. Your words stay there. Most AI writing tools send every keystroke to a server. TypeSeer doesn’t. It runs a language model directly on your Mac’s Apple Silicon, so your writing never leaves your device. - ✓ Every suggestion is written on your Mac. Nothing you type is sent anywhere - ✓ Once the model has downloaded, suggestions keep working with the internet off - ✓ Never suggests in password or secure fields - ✓ The only things that use the internet: downloading the model, a daily update check, and checking your license. Never your writing Curious how that’s possible on a laptop? Read how on-device AI autocomplete works on-device-ai-autocomplete.html . How it works Type. Glance. Tab. No new app to learn, no window to switch to. TypeSeer lives in your menu bar and works wherever your cursor is. Just start typing Write as you normally would: an email, a message, a document. TypeSeer quietly watches the box you’re typing in. A suggestion appears Grey text shows how your sentence could continue, right at your cursor. It never touches your own text until you say so. Tab to accept, or ignore it Press Tab to take the next word, and again for another. Type something different and it gets out of your way. Type what it says and it stays, shortening as you go. There’s a setting that makes two quick Tabs take the whole thing. System-wide One autocomplete, every app TypeSeer isn’t a plugin for one editor. It works at the system level, so the same assistant follows you across almost everything you type in. Not a fixed list. If an app uses a standard macOS text field, TypeSeer can generally work in it. See which Mac apps autocomplete works in mac-app-compatibility.html , including where it stays quiet on purpose. What sets TypeSeer apart It learns your words, in every language you write Two things a generic autocomplete can’t do: sound like you , and keep up when you switch languages. TypeSeer does both, entirely on your Mac. Learns how you write Optional, and off until you turn it on. TypeSeer remembers the sentences you finish, along with the words, names and phrasing you actually use, and offers them back when they fit what you’re writing now. - ✓ Learns only from finished sentences. Never from the one you’re still typing, or a suggestion you ignored - ✓ Text you accept can become part of a learned sentence once you finish it, just like the rest of the text in your document - ✓ Remembers the names and terms you use often, and only offers them when the context actually calls for them - ✓ Review shows every sentence it has learned. Export them, delete one, or clear the lot - ✓ Can learn each website separately, keeping the site address and nothing else Fluent in your languages TypeSeer works out the language of each thing you type and carries on in it. Switch languages mid-message and it follows, with no toggle to flip. It isn’t just the AI: spelling and word completion know the language too. - ✓ Dedicated dictionaries and word tables for 15 languages - English, Polish, German, French, Spanish, Italian, Portuguese, Dutch, Russian and more - ✓ Name the languages you write in pre-filled from your Mac so a Polish word is never flagged as an English typo - ✓ Notices a language you write but haven’t ticked, and offers to add it. Once, then never again More than autocomplete Small features that add up, all day long Everything is tuned for one goal: helping you type less without changing how you work. Fits the conversation TypeSeer can read the message you’re replying to, so suggestions match the thread instead of guessing. It reads only the window you’re typing in, never password fields, and setup asks before it reads anything. On-device AI, ready out of the box One built-in model, about 3.5 GB, tested to run well on every supported Mac. Advanced users can add another compatible MLX model from Hugging Face. Text snippets Type ;addr , press Tab, get your full address. Snippets support placeholders like date, time, and clipboard. Spelling fixes Misspell a word and TypeSeer offers the fix. One Tab and it’s corrected, even in apps with no autocorrect of their own. Optional grammar checking Add a model marked -it , -instruct or -chat and TypeSeer will proofread on your Mac. Off with the built-in model, and every fix is shown before it’s applied. Finishes the word you’re on Type “tomo”, press Tab, get “tomorrow”. TypeSeer uses the rest of your sentence to work out which word you meant. Writes in your language Works out the language of each sentence and carries on in it, even when you switch mid-document. 15 languages with their own dictionaries. You can see everything it learned Review lists every sentence TypeSeer picked up and where it came from. Export the lot, or delete one without wiping the rest.
