Save and search links via a Telegram second brain
Documented elsewhere: A Telegram AI agent sorts each message: a URL is saved, a question is searched, anything else gets a short how-to reply. Saving goes through a webhook that normalises the URL, reads the page with Jina Reader, and has an AI librarian write a summary and reuse existing categories. The builder describes the workflow as working: re-sent links update the existing card instead of duplicating, and unreadable pages are not filed.

Why it matters
Notes are only useful if you can find and connect them later. Agents that organise, summarise and link information make a personal knowledge base far easier to keep up. It is one of 44 sightings filed under Knowledge & Notes on Agent Sightings (number 19 by interest), and one of 36 involving n8n.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into n8n or any similar agent and adjust the details to your situation.
Notes task: save and search links via a Telegram second brain. Propose edits as a checklist, apply after approval, and finish with a short handover.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
