For PhD students, researchers and their teams: eleven scientific databases, AI that reads by your side, and a trajectory that shows where your question stands — not just what you've read.
A long-term question, its keywords, its corpus. The active problem drives everything else — down to the relevance score of every article you open.
One space: the notebook, the PDF and the AI tools at the tip of the “/”. Every AI answer points to the exact paragraph that backs it — you stay in control.
Established findings, dead ends, open fronts: your corpus laid out over time. The state of the question writes itself in one click — and exports as a synthesis report.
Search across all 11 databases is unlimited and free — no credit card. The Discovery plan also includes 20 AI credits per month to try the light analysis tools; paid plans add credits and unlock the advanced tools.
Every answer is generated by Claude (Anthropic) from the text of the articles in your corpus, and points back to the exact passage that supports it. A claim without a source has no place in the workspace.
