Reacti AI

Reacti AI targets a very specific habit: replying more and posting less. Its argument is that engagement in the comments drives far more visibility on Twitter and LinkedIn than another broadcast post, but writing thoughtful replies by hand takes time and most people fall back on generic praise. The extension removes that friction by generating a draft reply for the post you are currently looking at.

The workflow is deliberately light. You install the browser extension, open Twitter or LinkedIn, find a post worth replying to, click the Reacti AI icon, pick a tone of voice and a template, and hit Generate. The tool analyses the post content and produces a comment using natural language processing, which you can then edit to match your brand voice before hitting post. Beyond plain replies it also supports custom reactions, so you can build a set of reaction styles that sound like your own account rather than an AI.

Templates and prompts are the main lever for quality: users can use the built-in library or write their own to match a brand's messaging, and the tool is designed to work across languages, so replies can be generated in whichever language you choose. A free plan covers a limited number of comments per month, while paid plans remove the cap and unlock additional features.
