Top Free Alternatives To Paid Academic Research Tools 
"Finding high-quality research papers and academic resources usually means relying on paid platforms like SciFinder, Scopus, Web of Science, or Reaxys. However, there’s a collection of powerful free alternatives that provide access to journals, papers, and scientific data for students, researchers, and educators without subscriptions.
Here’s a breakdown of the most recommended and lesser-known tools that emerged from a thorough technical discussion:
- Google Scholar – A classic and still one of the best. Simple, fast, and reliable for general academic research: https://scholar.google.com

- Dimensions.ai – Offers a robust discovery platform with access to millions of publications and datasets: https://www.dimensions.ai
- Research Rabbit – Innovative research discovery and visualization tool: https://www.researchrabbit.ai
- Connected Papers – Visualize the evolution of scientific papers and map related work intuitively: https://www.connectedpapers.com
