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.

Genspark for Excel is an AI assistant embedded directly inside Microsoft Excel that lets users complete spreadsheet tasks through natural language commands. It writes formulas including advanced array functions and XLOOKUP, builds charts, generates pivot tables, analyzes datasets, and even pulls live web research — all without leaving the spreadsheet. The tool is designed for analysts, operations teams, and business users who live in spreadsheets but don't want to become Excel formula experts. Instead of googling syntax or copying StackOverflow answers, users describe what they need in plain English and the AI translates it into working Excel operations in place. Genspark has been building AI-native productivity tools since 2024. The Excel add-in is their most focused product yet — going deep on a single high-value workflow rather than building a general assistant. With a free tier available, the barrier to trying it is low for any Excel power user.
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've watched non-technical teammates struggle with XLOOKUP syntax for years. An AI that lives inside the spreadsheet and writes the formula for you in context is genuinely useful — especially since it can see the actual data structure to avoid type mismatches.”
“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.”
“Excel AI add-ins are a crowded category — Copilot in Microsoft 365 does most of this, and it's bundled for enterprise users. Unless the web research pull is meaningfully better than Copilot's, this faces a brutal incumbent.”
“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 most profound AI applications are the ones that meet users in their existing tools rather than forcing workflow changes. Embedding AI inside Excel — where billions of hours of knowledge work happen — has compounding impact that standalone AI apps can't match.”
“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 creators managing editorial calendars, audience data, and campaign analytics in spreadsheets, this is a practical daily-driver upgrade. Web research pulls inside Excel changes how you build data-backed content briefs.”
