Zhipu AI's open platform for GLM large models, multimodal APIs, and agent building
Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
Build tool-using agents and expose or consume MCP services to connect models to external systems.
Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
Tune models on your data and prototype prompts interactively in the browser before shipping.
The AI product manager for your entire team
Turn a sentence, transcript, or notes into a real PRD grounded in your Notion, Linear, GitHub, and Granola context.
A CPO-level review scores each document on strategy, structure, clarity, and completeness, then offers line-level edits you can accept in one click.
Build a clickable prototype straight from a spec, refine elements by pointing, and share a link the same day—or open in v0, Lovable, Bolt, or Cursor.
Pull context from docs, tickets, code, and meetings, then push finished work to Google Docs, Notion, Confluence, Linear, Jira, Slack, and Teams.
