Examples

1. 1.

   Replit uses LangGraph to power its AI coding agent - the graph defines states (planning, coding, testing, debugging) with conditional edges that retry on test failure, enabling reliable multi-step code generation.

2. 2.

   LinkedIn uses LangGraph for its Recruiter AI assistant - the graph orchestrates resume parsing, candidate scoring, outreach drafting, and scheduling steps with explicit state transitions and human-approval checkpoints.

3. 3.

   A hedge fund deploys a LangGraph-based research agent traversing states: company selection → SEC filing retrieval → financial ratio calculation → sentiment analysis → report generation - with durable checkpoints enabling multi-day runs.
