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.

Manus Skills is a new layer on top of the Manus autonomous agent platform that lets users capture multi-step workflows as reusable, parameterized 'Skills.' Once saved, a Skill can be re-run with different inputs, shared with teammates, or published to a community library. Think of it as turning an ad-hoc agent session into a repeatable automation — like a macro, but with LLM intelligence at each step. The feature addresses one of the core frustrations with current agent platforms: every task starts from scratch. Manus Skills lets power users encode their best prompting patterns and workflow sequences into durable primitives. A research Skill might chain web search, source validation, and structured output; a content Skill might handle drafting, image sourcing, and formatting in sequence — all re-runnable with a single input parameter. Launching today as a Product Hunt pick, Manus Skills signals the platform's evolution from a chat-based agent into a workflow automation tool with a community knowledge layer. If the Skills marketplace takes off, Manus could become the Zapier of LLM-native automation — with the added power of reasoning at each step.
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.”
“Parameterized agent workflows that actually persist and share — this is the missing piece in nearly every agent platform. The ability to encode prompting expertise into a Skill and share it with a team removes the 'prompt whisperer' bottleneck entirely.”
“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.”
“Manus still has reliability and hallucination issues in complex multi-step tasks. Wrapping unreliable agent runs into 'Skills' and calling them reusable just scales the failure modes. The community library angle will also inevitably fill with low-quality Skills that break as models update.”
“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.”
“Composable agent skills are an early step toward a true agent app store. The long-term vision — where the best human knowledge workers encode their expertise into Skills that anyone can run — is genuinely transformative. Manus may not be the final form, but this is the right direction.”
“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.”
“As a creator who runs the same research-to-draft workflow daily, having a Skill I can launch in one click versus rebuilding it from chat each time is a real productivity unlock. The sharing aspect means I can finally pass my best workflows to collaborators.”
