Decision notes
Official-document research
Based on the cited documentation. We did not use the product, purchase a plan, or run quality, speed or reliability tests in this review.
Consider it for
- Researchers checking papers and developers confirming API/data permissions
Choose another approach if
- All papers freely licensed or every summary verified
- Unlimited API throughput or assumed commercial permission
Pricing and conditions
Documented terms
The FAQ describes free Web research access and free account creation; publisher subscriptions and reuse rights are separate. API overview states unauthenticated traffic shares1000RPS across all users, may be further throttled, and keys start at1RPS; some endpoints require keys. This is not a personal throughput guarantee or blanket free commercial license. Expanded access, any fees/ISO currency/taxes/region, quota increases and dataset contracts were not confirmed. No account, key or API call was requested.

Pricing or terms sourceCode, model and service licensing
Free search is not an open-source, model or paper license. Authors/publishers and dataset licenses govern reuse. The May2023 API text separates S2 data licenses and permits input use to provide/improve services; the API-hosted agreement instead describes internal noncommercial research/education and expanded commercial permission, with a narrower input-use promise. Confirm the controlling channel/contract. General Ai2 terms reserve broad user-content licensing/training unless specific terms differ; they do not prove every API trains. Usage/account/search data and necessary/legal retention remain. No universal no-training or deletion deadline was verified.
Basis and limits of the recorded score
Original 4.6/5 retained; the original scoring worksheet and hands-on evidence are unavailable. This document review did not re-score it.
Overview
Semantic Scholar is Ai2's scientific-literature discovery service. Its FAQ describes search, libraries, alerts and research feeds; AI TLDR summaries are limited to available papers in computer science and biomedicine. Graph, recommendation and dataset APIs have separate access conditions.
Discovery does not confer access to every paywalled paper or permission to republish it. Read original sources and check licenses. The two published API agreements differ in permissions and data use, and the general Ai2 terms do not override every specific API/data contract.
