Extract post-call glossary terms from transcripts with Anthropic Claude and Telegram

Quick overview This workflow accepts a meeting transcript via an n8n form or webhook, uses Anthropic Claude to extract technical terms and acronyms into a JSON glossary, and then sends either the formatted glossary or a “nothing to add” confirmation to Telegram.

How it works Receives a transcript either from an n8n form submission or from an HTTP POST webhook. Normalizes the incoming payload into consistent transcript and sessionId fields. Sends the full transcript to an Anthropic Claude chat model to extract distinct technical terms and short definitions as a strict JSON block. Parses the model’s JSON response into structured fields and checks whether any terms were found. Formats a numbered glossary message when terms exist and sends it to a Telegram chat. Sends a short “Nothing to add” message to Telegram when no relevant terms are found.

Setup Add an Anthropic API credential and select the model in the Anthropic Claude chat model node. Create a Telegram bot, add Telegram credentials in n8n, and replace `` with your target Telegram chat ID in both Telegram send steps. If using the webhook trigger, copy the webhook URL and configure your transcription tool to POST JSON like { "transcript": "...", "sessionId": "optional" } to the post-call-glossary endpoint.
