# Skimless vs NotebookLM

NotebookLM is strong when you want to work with a specific set of documents. Skimless is built for a different job: a recurring daily brief from sources that keep changing.

The question is not which tool is better in general. The question is whether you need a notebook or a briefing habit.

## When NotebookLM is enough

NotebookLM can be a good fit if:

- You already have a fixed set of documents
- You want to ask questions across those docs
- You are researching a specific topic
- You want a workspace for notes and source material
- The source set does not need daily monitoring

For document research, that workflow can be excellent.

## Where recurring source monitoring is different

Daily source monitoring has a different shape. The sources change over time: newsletters publish, YouTube channels upload, docs shift, changelogs update, and feeds add new items.

The job is not only to understand a static corpus. It is to decide what changed today and whether it matters.

## Where Skimless fits

Skimless starts from the sources you follow and turns new changes into a daily brief. The brief is designed to save skimming time:

1. What shipped?
2. What changed?
3. What can I ignore?

That makes it useful for founders, developers, product teams, consultants, and operators who track the same moving sources every week.

## Best choice

Use NotebookLM when you want a research notebook. Use Skimless when you want a source-led daily brief from newsletters, YouTube, feeds, docs, and changelogs.
