Typeahead 2.0

Private AI autocomplete that finishes your sentences in any app on your Mac

Overview

Typeahead does one thing: it finishes your sentences. It sits quietly in the background on your Mac and, wherever you're typing, from an email to a Slack message to a Notion doc, it offers to complete your thought. The pitch is that it runs the whole model locally, so unlike browser-based writing assistants, nothing you type gets sent anywhere. Version 2.0, which launched on Product Hunt in July 2026, adds per-app writing styles (so you can tell it to keep Slack casual and Mail buttoned-up), better context awareness within a conversation, and support for any language rather than just English.

It's a one-time $79 purchase, not a subscription, which is refreshing in a market full of monthly AI fees. Early Product Hunt reception was warm, 499 upvotes and a clean 5-star average, but that's based on a small handful of written reviews, not a large independent track record. It's Mac-only, there's no mobile version, and because it's a system-wide keyboard-level tool, it needs a fair bit of trust before you let it read everything you type. If you live on a Mac and want fewer keystrokes without sending your words to the cloud, it's worth a look. If you're on Windows, or you want a tool with years of reviews behind it, this isn't that yet.

Key Features

  • System-Wide Suggestions: Inline autocomplete works in any real text field on your Mac, from Mail and Slack to browsers and code editors.

  • Per-App Writing Styles: Set plain-English instructions per app, so Mail stays formal and Slack stays casual, and Typeahead switches automatically.

  • Fully Local Processing: The model runs on-device, so your writing never leaves your Mac and it works offline.

  • Smarter Context: Version 2.0 picks up on the conversation you're already in, so suggestions match what's actually being discussed.

  • Multilingual Support: Suggests in whatever language you're typing, with the app interface localized into 16 languages.

  • Sensitive-App Safeguards: Auto-disables in password managers and finance apps, and app-by-app enabling is opt-in.

Pricing

Starting price

$79/one time

  • Early Access: $79 one-time payment. Unlimited usage, all supported language models, free lifetime updates, 30-day money-back guarantee.

  • Regular Price: Listed as $149 one-time on the site, with $79 framed as a limited early access discount rather than a permanent tier.

Disclaimer: pricing may change, confirm current pricing on Typeahead's own site before buying.

Pros

  • Genuinely Local: The model runs on-device, so your writing isn't sent to a server, and it still works offline.

  • No Subscription: One $79 payment with free updates, instead of another monthly AI bill.

  • Works Everywhere You Type: Not limited to a browser or one app, it follows you into Mail, Slack, Notion, and more.

  • Adapts Per App: Early users specifically called out that it saves real time on emails and Slack replies.

  • Lightweight in Daily Use: Product Hunt users noted v2 feels lighter on memory and faster than the original release.

Cons

  • Thin Track Record: Public reviews are limited to a handful of Product Hunt comments; there's no large body of independent, long-term reviews yet.

  • Mac Only: No Windows or mobile version, so it's a non-starter if you're not on a Mac.

  • Sizable Local Footprint: The on-device model is roughly 5GB, which is a real download and disk commitment for what is essentially an autocomplete tool.

  • System-Level Access Required: It needs to read text across your apps to work, which is a legitimate trust hurdle even with local-only processing claims.

  • Launch Pricing Is Temporary: The $79 rate is called an early access special reduced from a stated $149, so the long-term price isn't locked in.

What Makes It Unique

  • System-Wide, Fully Local Autocomplete: Unlike browser-bound writing tools like Grammarly or cloud-based assistants, Typeahead completes your sentences across every Mac app while keeping the model entirely on-device.
