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.

illumi is an AI visual workspace designed around one thesis: "execution got cheap overnight, but comprehension didn't keep up." The founders argue that modern AI tools accelerate output production but fragment the thinking process — each conversation starts fresh, context gets lost, and knowledge workers spend more time reconstructing mental models than doing actual work. The tool maintains session continuity across work phases: raw notes and messy thinking in early sessions are preserved and connected to the polished deliverables they eventually become. AI assists at each stage — synthesizing scattered notes into structured frameworks, drafting deliverables from frameworks, and flagging when new context contradicts earlier decisions. The workspace is designed to make the evolution of a project's thinking visible, not just its final outputs. illumi launched on Product Hunt on April 21, 2026 with 92 upvotes and sparked one of the more substantive discussions of the week — a thread titled "Is AI making knowledge work harder, not easier?" resonated strongly. A two-founder indie team built it. At this stage it's an early product with a clear POV, targeting knowledge workers who feel increasingly productive but increasingly confused about their own work.
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 problem statement is accurate — I have a graveyard of ChatGPT conversations that led to good decisions I can no longer reconstruct. A tool that preserves the reasoning chain from messy brainstorm to shipping decision is worth trying. Whether illumi actually does that at v1 is the real question.”
“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.”
“'Session continuity' and 'preserved thinking' are features that require deep integration into how you actually work — and most people won't restructure their workflow around a new tool unless it's dramatically better from day one. The 92 PH upvotes suggest interest, not retention. Come back in six months.”
“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.”
“The 'cognitive overhead of AI' problem is real and growing. We're heading toward a world where AI-generated outputs vastly outnumber human-reviewed outputs — tools that make the thinking process durable and auditable aren't productivity luxuries, they're organizational infrastructure.”
“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.”
“For content strategists and writers who live in the messy middle of multiple projects, a workspace that connects early ideation to final drafts without losing the 'why' behind every decision addresses a daily frustration. The visual approach feels right for how creative thinking actually works.”
