Open Knowledge Maps

AI-powered visual discovery of scientific knowledge

Visual knowledge maps

Every search produces an interactive concept map in which related research outputs are grouped into labeled, clickable clusters instead of a single flat list.

400M+ research outputs

Searches more than 400 million records in over 400 languages pulled from more than 11,000 sources through the BASE aggregator.

25 output types

Beyond journal articles, results span datasets, software, images, and other research objects, giving a broader picture of a topic.

No AI hallucination

Maps are generated from metadata rather than synthesized text, so what you see corresponds to real indexed records.

Strengths & Pros

+Completely free with no account or installation required
+Visual clustering makes the structure of a topic obvious at a glance
+Nonprofit, open-science mission with an open source codebase
+Metadata-driven results avoid the hallucination risk of text-generating search tools

Strengths & Pros

+Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.
+Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.
+Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.
+Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

Limitations

–The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.
–Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.
–Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
