How does the Soku AI integration work?

How does Lark compare to Slack?
Lark is an all-in-one platform with native docs, sheets, project management, and video conferencing built in — whereas Slack focuses on messaging and relies on third-party integrations for other capabilities. Lark also offers 100 GB free storage (vs Slack's 5 GB) and 18-language real-time auto-translation.
What is Lark Base?
Lark Base is a no-code database similar to Airtable, built directly into the Lark workspace. It supports Kanban boards, Gantt charts, dashboards (pulling from up to 200 data sources), and automation workflows. Ad creative teams use it to track campaigns, manage asset libraries, and build content calendars.
Does Lark have an API?
Yes. Lark's Open Platform offers 2,500+ APIs across 12 business domains including Messenger, Docs, Drive, Base, Sheets, Tasks, Wiki, Calendar, Mail, Meetings, Contact, and Approval. Authentication uses OAuth 2.0 with both tenant-level and user-level tokens. There is also an official MCP server for AI assistant integration.
What is the difference between Lark and Feishu?
Lark is the international version, with data stored in Singapore and designed for global teams. Feishu (飞书) is the China version, with data stored in Beijing. The two platforms operate independently and have limited cross-platform compatibility.
Can Lark help with multi-language ad campaigns?
Yes. Lark's 18-language real-time auto-translation enables creative teams across different countries to collaborate seamlessly. Briefs, feedback, and campaign updates are automatically translated in chat, making it ideal for brands running multi-market ad campaigns with Soku AI.
