How to use Liner
- 1Use Liner as a "search portal with citations" and always check the original sources for key conclusions before citing them.
- 2When writing academic content, first ask it to list candidate papers, then manually select them to be included in the review literature, and avoid directly copying the structure of the review.
- 3When asking follow-up questions, limit the questions to specific dimensions (time range, region, metrics), and the verifiability of the answers will be significantly improved.
- 4Mind maps are suitable for structuring and organizing ideas when proposing a thesis or initiating a project, and the original citations should be the primary reference during the final writing stage.
- 5If you integrate it into your own workflow via API / MCP, first confirm the call limits and data retention rules, as the official policies may be subject to change.
