Frequently Asked Questions
Semantic Scholar vs Stilta: which should you choose?
Don't let the 'AI search' label fool you — Stilta and Semantic Scholar serve completely different jobs. If you're a patent attorney needing defensible invalidity or infringement analysis, Stilta's agentic search with 100% prior-art recall is essential (but costs enterprise money). If you're a researcher or student exploring 236M+ papers, Semantic Scholar is unbeatable at free. Pick the tool that matches your workflow, not the category.
Can Semantic Scholar help with patent validity searches?
No. Semantic Scholar focuses on scientific papers, not patents or legal literature. For patent-specific prior art, use Stilta.
Does Stilta have a free tier or trial?
The data doesn't mention a free tier — only 'contact sales.' Expect an enterprise-only model.
Can I use Stilta for non-patent research?
Stilta searches scientific literature but is purpose-built for patent analysis. For general scientific discovery, Semantic Scholar is more appropriate.
Are there limits to Semantic Scholar's API?
The data notes a 'significantly improved API with better documentation and stability' and that it's free, but does not specify rate limits.
Which tool offers collaboration features?
Neither tool is described with collaboration or annotation tools. Both are individual discovery/analysis platforms.
Does Stilta guarantee no data leakage?
Yes — the data explicitly states 'Zero AI training on user data' and 'Per-tenant isolation by default,' critical for confidential patent work.
Does Semantic Scholar have a mobile app?
The data does not mention mobile platforms; it only describes in-browser reading and API access.
Can I use both tools together?
Yes — use Stilta for legal-grade patent analysis and Semantic Scholar for broader scientific context or prior art in non-patent literature.
