闪电说 (Shandianshuo) is a communication agent and AI voice input tool developed by Tanwei (Wuhan) Technology Co., Ltd. It helps users communicate more clearly and naturally across messaging apps and other software, including email, browsers, and terminals. With a short press of a shortcut, users can speak and have their words organized into clean text, with repetition removed, errors corrected, and names or technical terms recognized through a personal dictionary.

A long press activates “Help Me Say,” which uses screen context, communication memories, and knowledge resources to draft an appropriate response. Users can add product information, preferred wording, and frequently used replies to the knowledge base. The tool also offers skills that can call tools, retrieve data, run code, or imitate a writing style before turning results into a ready-to-send message.

Its memory feature can retain and update details such as people’s preferences and prior context. Shandianshuo offers Mac and Windows downloads, with Android, iOS, HarmonyOS, and Linux versions available through testing programs
