According to CoinMeta, Tencent has launched a collaborative editing feature on AI, which supports Word, Excel, and PPT. Users can directly open Word, Excel, PPT, and Markdown files, select a piece of text, a group of cells, or a page of PPT, and allow AI to make modifications in place. AI only affects the specified area, while trying not to disturb the rest of the content and layout. Users can view the changes, continue to edit manually, or revert the results. Word supports continuous writing, polishing, and formatting; Excel enables data analysis and chart generation; PPT allows for page splitting, layout adjustment, and the creation of presentation notes. However, such features have already been available in OpenAI's Codex.
