Featured Function Operation

Multiplayer Collaboration

Chord allows up to 20 people to participate in a group chat at the same time, making it suitable for team brainstorming, project discussion or decision making. For example, teams can discuss marketing strategies while @AI models generate data analysis or creative suggestions in one chat. Chat transcripts are saved in real-time, so new members can quickly get the background.

Multi-AI model interaction

Users can invoke different AI models in the same conversation. For example, when discussing product design, @Gemini can be used to generate an idea description, @Claude to perform logical analysis, and @ChatGPT to provide user experience suggestions. Responses from each model are clearly labeled so users can quickly compare the output of different AIs.

document analysis

After uploading a document, the AI can answer questions based on the content of the document. For example, after uploading a market report, type "@Claude extract key data from the report" and the AI will return a summary. Users can also ask the AI to generate charts or further analysis, making it ideal for data-driven team collaboration.
