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.

MiniAi is a macOS menu bar app with exactly one job: explain selected text without breaking your focus. Highlight any text on your Mac — in a PDF, email, code file, web page, or document — press Option+Space, and a floating AI explanation panel appears. No app switching, no copy-paste, no context loss. Built by a medical student who needed to stay in reading flow while looking up terms in research papers, MiniAi uses Claude Haiku under the hood for fast, accurate explanations. The floating panel dismisses with Escape and leaves no trace in your task switcher. The scope is deliberately minimal: one gesture, one action, instant result. No chat history, no threads, no settings overwhelm. Free to use with your own Anthropic API key. Launched today on Product Hunt where it resonated strongly with students, researchers, and professionals who live in document-heavy workflows.
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.”
“The Option+Space shortcut is muscle memory within 10 minutes. BYOK with Haiku means it's essentially free at typical usage — Haiku is fast and accurate enough for term lookups and quick explanations. The zero-UI-overhead philosophy is exactly right for a tool you invoke 20 times a day.”
“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.”
“Apple's own Writing Tools in macOS 15 already has a 'Summarize' action in the right-click menu, and it's free with no API key. PopClip has been doing triggered text actions for a decade with a rich ecosystem of extensions. MiniAi needs a clearer differentiator beyond the keyboard shortcut.”
“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.”
“Tools like MiniAi are training users to expect ambient AI assistance — intelligence available at any moment without mode-switching. This behavioral shift is significant: once people get used to instant contextual explanation, the bar for every reading and research tool permanently rises.”
“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.”
“The story behind MiniAi — built by a med student to stay in flow during paper reading — is authentic and the design reflects genuine user empathy. For writers, researchers, and anyone working with dense material, this is the kind of tool you install and forget you installed because it just works.”
