Newsletter research with Comet
Perplexity Comet loaded NotebookLM with Reddit sources and analyzed Substack note performance for a newsletter author over a week of testing.
Comet added Reddit threads plus 10 Discover sources to NotebookLM in about 15 minutes unattended, then extracted 67 notes for analysis in 25 minutes.
Overview
How it was set up
Perplexity Comet browser agent working across tabs with NotebookLM's Add Source and Discover features and the Substack Activity page, driven by copy-paste prompts.
Worth knowing
Comet kept stopping after 15-20 notes and needed repeated prompting; the note extraction ended up slower than doing it manually.
A prompt to start from
Research task: add [NUMBER]+ [SOURCE TYPE] about [TOPIC] to NotebookLM. Use Add Source to input URLs, then use Discover to find related sources on [TOPIC] and add them all. Goal: a notebook covering [WHAT YOU WANT TO ANALYZE].
