ClarifierAI is an iOS keyboard extension that rewrites, shortens, formalizes, or translates text directly inside any app — Gmail, WhatsApp, iMessage, LinkedIn, Slack — without copy-pasting to a separate tool. It highlights changed words individually so you can revert specific edits rather than accepting or rejecting the whole rewrite. The extension supports 113 languages for translation and applies multiple tone styles (professional, casual, concise, persuasive). Unlike AI writing tools that live in separate apps or web tabs, it hooks directly into the iOS keyboard so the friction between drafting and AI polishing is eliminated. The granular word-level undo is the differentiating feature: most AI rewrite tools show you a before/after and force a binary choice. ClarifierAI lets you keep 'the client called' but revert 'and was disappointed' back to your original phrasing. That level of control turns it into an editing collaborator rather than a replacement.

Dune is a compact hardware keypad for Mac that detects your active application and automatically remaps its three keys in real time — no manual profile switching required. In GitHub it raises PRs and approves changes. In Zoom it mutes your mic and joins calls. In Claude Code or Cursor it triggers your agentic workflows directly from your desk. The device syncs with your calendar so meeting-join actions appear automatically before calls. It supports Zoom, Teams, and Google Meet natively. The maker community angle is notable: Dune users can program custom agent triggers to kick off any AI workflow from a physical button press. Dune topped Product Hunt's weekly leaderboard for the week of April 20 with 589 upvotes — a strong signal that developer-focused hardware AI accessories are a real market. This isn't just a fancy macro pad: the context awareness removes the mental overhead of remembering which key does what across 12 different apps.
Reviewer scorecard
“The keyboard extension model is the right approach for mobile AI writing — context switching to a separate app kills the workflow. Word-level undo is also a genuinely smart UX decision that I haven't seen elsewhere. The 113-language support is impressive; tested it on technical Japanese documentation and it held up.”
“I lose an embarrassing amount of time hunting for the right shortcut in the right app. Having a physical device that reconfigures itself automatically is exactly the kind of ambient tooling I want on my desk. The AI agent trigger support is the killer feature.”
“iOS keyboard extensions have always had friction with enterprise apps — many corporate MDM policies block third-party keyboards, and for good reason since they technically have access to everything you type. The 'no keylogging' claim is standard but unaudited. I'd verify the privacy policy very carefully before using this anywhere sensitive.”
“Three keys is a very limited surface area for the price, and context detection reliability in niche dev tools is going to be hit-or-miss. A well-configured Stream Deck with a few profiles does 90% of this for less money.”
“The keyboard is the last interface layer before human intention becomes digital text — whoever owns it owns a uniquely powerful position. As AI writing assistance moves to be ambient and always-available, the keyboard extension model will outcompete dedicated apps. ClarifierAI is early but the positioning is right.”
“Physical buttons for AI agents are the beginning of a real ambient computing shift. As agentic workflows mature, having dedicated hardware triggers rather than keyboard shortcuts buried in menus is going to feel necessary, not optional.”
“Word-level granular undo changes the relationship with AI writing assistance from 'accept or reject' to actual collaboration. As someone who writes a lot from mobile, not having to copy text to a separate app and back is genuinely meaningful. The tone modes (casual → professional) are well-tuned — not as robotic as most AI rewrites.”
“Context-switching kills creative flow. Having a keypad that automatically knows I'm in Figma versus in my writing app and changes its keys accordingly is worth a lot. Would buy this immediately for video editing alone.”
