What is the best deep research ai tool?

An AI answer engine with an agent mode that plans multi-step work and runs connectors, with a model picker spanning free open models and paid GPT, Claude, Gemini and Grok tiers. The live site positions it as a cheaper alternative to Perplexity and Comet, with plans from Free to a $179 Power tier.

Compare tools on the same research questions using citation accuracy, coverage, freshness, latency and cost. A strong result for one subject does not establish a universal winner. Preserve the original responses and source links so another reviewer can repeat the assessment.
