Tips & best practices

Get better summaries, faster

Pro tips to maximize your summarization results.

1

Choose the Right Length

Use brief for a quick overview, concise for emails, detailed for reports, and bullets for presentations. Match the format to your audience.

2

Summarize by Section

For documents over 30 pages, use section-by-section mode. You get a summary of each chapter, making it easier to navigate to specific parts.

3

Check the Key Points First

Always read the extracted key points before the full summary. If the points cover what you need, you might not need the detailed summary at all.

4

Use Entity Detection for Research

When reviewing multiple papers, check the detected entities to quickly see which authors, methods, or datasets are mentioned across documents.

5

Export as Markdown

If you use note-taking apps like Obsidian or Notion, export as Markdown. The formatting carries over perfectly with headers and bullet points.

6

Batch Summarize for Literature Review

Upload 10-20 papers at once and generate brief summaries for all. Use these to decide which papers deserve a full read.
