Kategorieratgeber91 dokumentierte Tools
Students, analysts, founders and developers all search the web for answers, but they need different things from it. Some want cited reports, some want to analyze spreadsheets or PDFs, and some want raw data feeds for their own agents. This page covers 91 tools in the Research & search category, including AI research tools for academic, market and data work. Perplexity is an AI answer engine that searches the web and replies with cited sources, Liminary and Innogath link source citations, and Crunchbase covers private company data.
The biggest difference is how you pay. Of the 91 tools, 60 offer a free plan or free credits and 61 list a verified starting price. Many bill by credit packs or one-time purchases rather than a monthly subscription, such as Owlytics.ai at $29.99 per pack, while others charge flat monthly or annual fees.
