What this workflow does
This AI workflow has 25 nodes and runs on Telegram events (message) (plus 1 other trigger). Along the way it connects Telegram, Supabase Vector Store, Embeddings OpenAI and OpenAI Chat Model and 2 more.
How it runs
Trigger: On Telegram events (message) (plus 1 other trigger).
- If: checks a condition and branches into true / false
- Typing.... (Telegram): send chat action
- Hook Analyse Agent (AI Agent): runs an AI agent, with model: 4o mini, 2.5-flash; output parser: Structured Output Parser
- LinkedIn Post URL (HTTP Request): calls an HTTP API
- Wrong URL (Telegram): uses Telegram
- Post Structure Agent (AI Agent): runs an AI agent, with model: 4o mini, 2.5-flash; output parser: Structured Output Parser
- Scrap Content (HTML): parses or builds HTML
- Unable to Scrape (Telegram): uses Telegram
- Post Generator Agent (AI Agent): runs an AI agent, with model: 4o mini, 2.5-flash; 1 tool (Supabase Vector Store); output parser: Structured Output Parser
- Upload Document (Supabase Vector Store): stores documents in the Supabase vector store, with embeddings: Embeddings; document loader: Data Loader
…plus 3 more steps. See the full node list below.
Services it uses
