[1.5.2] - 2026-01-31 : Duplicate Source Scanner 📂

Duplicate Source Scanner 📂

Ever feel like you're seeing double? We noticed it’s way too easy to upload the same document twice (or three times). Our new scanner helps you clean up the clutter so your NotebookLM stays organized and within source limits.

What’s new:

• Fast & Deep Scan modes: Quickly find identical filenames or dive deep into content similarity.

• Review before you delete: A new review step lets you decide whether to delete, or keep duplicates.
