Finding answers with AI can also mean deciding which sources to inspect and how to pursue a question further. Compare citation formats, source filters, and deep research modes, along with API access and browser extensions that may suit your workflow. Mobile apps and monthly query limits help clarify how you can access a service; free plans and paid-from prices add cost context. Perplexity, Genspark Design, and Andi AI are among the entries, alongside Consensus and Felo Search.
