For researchers, PhD candidates, and analysts

Map cross-domain idea transfer in your literature

Researchers don't read in straight lines. Hikara turns your literature into a knowledge graph so you can see ECHOES, CHALLENGES, and BRIDGES across your sources — and spot the gaps.

The literature-review problem

  • You've read 200 papers and books across three sub-fields. The connections live in your head, badly.
  • Citation graphs only show who cited whom — they don't show ideational tension.
  • You suspect a gap exists between two literatures, but you can't see it from a list.
  • Reviewers ask "have you considered X?" and you realize you'd already read X but missed the link.

How Hikara helps researchers

See your literature as a knowledge graph

Force-directed layout naturally clusters books by ideational proximity. Cross-domain transfers show up as long edges between clusters — exactly the bridges that make a thesis novel.

Find counter-positions you've missed

CHALLENGES are weighted relations — Hikara shows you which of your sources sit in productive tension. Useful for falsifiability checks and identifying your strongest objections.

Bridge two literatures with one book

Pick 2–5 sources spanning fields and use the gap finder. Hikara recommends one book whose addition would meaningfully bridge them — useful for structuring inter-disciplinary chapters.

Cite better arguments

Each connection is scored 0–100 with an AI rationale you can use as a starting prompt for your own argument. Treat connections as hypotheses to verify, not assertions to copy.
