The best AI tools for researchers in 2026
A literature review demands current citations, long-context reading and careful synthesis. TulexAI gives researchers Perplexity, Opus 5 and Gemini 3.1 Pro in one $11/month plan, so finding sources and digesting them stop being two products.
Literature work needs sourcing and synthesis in the same place: Perplexity Sonar surfaces cited evidence, Gemini 3.1 Pro swallows several full PDFs at once, and Claude Opus 5 turns them into a structured review you can defend. TulexAI puts all of that behind one login from $11/mo.
