## autocomplete

autocomplete is a Chrome extension that finishes your sentences as you write. Built on OpenAI's GPT-3.5, it shows inline suggestions while you type in Gmail, Outlook and ChatGPT, so you can draft replies and prompts with far fewer keystrokes.

**價格與方案:** Free to install from the Chrome Web Store, with optional in-app purchases. No card is required to add the extension.

- **Inline AI autocompletion:** As you type, the extension proposes the rest of your phrase in-line, so you accept rather than write it out.
- **Works inside Gmail, Outlook and ChatGPT:** Suggestions appear in the text boxes you already use for email and AI chat, with no separate editor to open.
- **Powered by GPT-3.5:** Completions are generated with OpenAI's GPT-3.5 model, which keeps suggestions fast and natural-sounding.
- **One-key accept flow:** Keep typing to dismiss a suggestion or hit the accept key to insert it, matching the Copilot-style habit many users already have.
- **Lightweight Chrome extension:** A small install of under a megabyte that sits quietly in the browser and activates only on the supported sites.

**優勢:** Removes repetitive typing in the tools you already use every day; Feels familiar to anyone who has used GitHub Copilot; Very small download and quick to set up; Free to install with an optional paid upgrade

**限制:** Only supports Gmail, Outlook and ChatGPT rather than the whole web; Runs on GPT-3.5, so output quality trails newer models; Typed text is sent to OpenAI for processing, which matters for confidential content; Store listing shows a low overall rating and has not been updated since mid-2023

## Typeahead

Typeahead is a system-wide AI autocomplete app for Mac that completes your sentences inside the apps you already use, running entirely on your machine so your writing is never sent to a server.

**價格與方案:** Typeahead is a paid macOS application. Its website offers a direct 'Get Typeahead' option and a waitlist rather than a published price list, so check the site or the Mac app store listing for current licensing and pricing details.

- **Sentence completion where you already type:** Faint ghost text completes the word or sentence you are typing right at the cursor. Tab accepts the entire suggestion, the right arrow takes just the next word, and Esc dismisses it so you stay in control.
- **Private by design and offline capable:** The model runs on your Mac rather than in the cloud. Typeahead never sends your writing to a server and keeps working offline after setup, which makes it suitable for work email and sensitive documents.
- **Screen and clipboard context:** It reads what is on screen and what you copied to the clipboard, so replies fit the thread you are actually answering rather than being generic filler.
- **Per-app writing styles and your own colour:** Set a voice per app, professional in Mail and friendly in Messages, choose from seven color-blind-safe highlight shades, and tune suggestion timing to instant, balanced or only when you pause.
- **Learns your phrases and shows time saved:** It learns your go-to lines and the way you phrase things, including names and terms your Mac dictionary does not know, so two words can bring back a sentence you write often. Insights shows the time saved, with the site citing up to 30% faster typing.

**優勢:** Completes your sentences in place, so you never leave the app you are writing in or copy text back from a chatbot; Runs locally on your Mac and never sends your writing to a server, with offline support after setup; Learns your own phrases and personal vocabulary, so suggestions sound like you rather than like a generic model; Screen and clipboard context make replies fit the actual thread or document

**限制:** Currently Mac-only, so Windows, Linux, iOS and Android users cannot use it; The site still shows a waitlist alongside 'Get Typeahead', which can suggest availability is being rolled out gradually; Because it only completes text where you already type, it will not draft a long document or research a topic for you the way a chat assistant will; Per-app writing styles and learned phrases take a little setup before the suggestions feel genuinely personal
