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.

CraftBot is a self-hosted, proactive AI assistant that runs locally 24/7. Unlike chat-based AI tools, it continuously works toward user-defined objectives — breaking them into tasks and initiating action rather than waiting to be prompted. Its standout feature is Living UI: custom apps and dashboards the agent builds inside CraftBot that stay aware of their own state, letting the agent read, write, and act on UI data directly. Users can import, build, or evolve Living UIs as their needs change, turning CraftBot into something between a personal agent and a self-modifying software platform. MCP integrations, Skills, and external app connections let it reach into third-party services while remaining fully local. The agent harness is MIT-licensed. CraftBot first launched on Product Hunt on April 18, 2026, earning #3 Product of the Day with 263 upvotes. Today's re-feature on Product Hunt's front page (123 votes) follows a significant update shipping the Living UI evolution system — where UIs built by the agent adapt in real time as your goals and workflows change.
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 Living UI concept is genuinely novel — having the agent maintain awareness of custom UI state and act on it directly blurs the line between app and agent in a productive way. Self-hosted with MCP support checks all the right boxes for privacy-conscious developers who want real automation.”
“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.”
“A 'proactive' AI running 24/7 sounds great until it's doing something you didn't intend at 3am. The Living UI concept is interesting but means you're trusting a locally-running agent to mutate your own tools autonomously. Requires careful configuration and a level of trust most users haven't earned with any AI system yet.”
“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.”
“Software that evolves its own interface based on how you actually use it is a genuinely new interaction paradigm. CraftBot is an early implementation of something much larger — the self-modifying personal software stack where apps and agents are the same thing.”
“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.”
“A proactive creative assistant that builds its own tools around my workflow is exactly what I've wanted. The Living UI concept applied to a content calendar or creative project board could be genuinely transformative for how I manage long-form projects.”
