Summarise a Literature Review Across Multiple Sources

You've read a stack of papers and your notes are a sprawl of highlights and half-quotes with no shape. This pulls them together: the two to four themes that keep recurring, where the sources agree and clash, and the gaps nobody's filled. You get a coherent overview to build your own review on rather than a pile of fragments.

4. Group sources by their theoretical approach or methodology
5. Suggest a logical order of themes for structuring the written review
