KI-Tools, um Quellen, Studien und Dokumente zu finden, zu lesen und zusammenzufassen.
Unsere Top drei KI-Recherche-Tools
These three do different jobs more than they compete. Elicit comes first for finding papers: its free plan has no cap on search, summaries or chat with papers. ChatPDF is second for asking questions of a document you already have. Semantic Scholar is third as the search engine with nothing to pay. Consensus narrowly missed: its free tier stops at 10 Pro messages and 3 Deep Searches a month, and its paid prices could not be confirmed. Anara answers across a whole library of files but has no Windows or Android app. ResearchRabbit maps how papers connect, free with unlimited searches.
Platz 1: Elicit
Gratis-Plan · ab $49/monat
Für: Most people looking for papers on a research question
Elicit searches more than 138 million academic papers from a research question, not exact keywords. Its free Basic plan includes unlimited search, unlimited paper summaries and chat with papers, plus Zotero import. A Research Agent writes cited reports, and a separate workflow handles screening and data extraction for systematic reviews. Know the limits: it runs in a browser, with a Chrome extension and no phone or desktop app listed. Research Agent and report usage is limited on Basic, the systematic review workflow starts at Pro, at $49 per user a month billed annually, and the $11 academic Plus plan appears only when Academic is selected on the pricing page.
Elicit: Preise und DetailsPlatz 2: ChatPDF
Gratis-Plan · ab $89.99/jahr
Für: Anyone with a document to question, not papers to find
ChatPDF answers questions about a file you bring: a PDF, Word, PowerPoint, Markdown or text file, or a YouTube or website link, with the answer shown beside the source and clickable citations. The free plan covers 2 documents and 20 messages a day and works without an account, and it runs on the web, Mac, Windows, iPhone and Android. It is second because it reads what you give it more than it searches: its paper summaries are built from abstracts, and chatting with a full paper works only for open-access papers. Free files stop at 120 pages or 10 MB. Plus is $14.99 a month or $89.99 a year on the US App Store, and the website sets its own price per visitor.
ChatPDF: Preise und DetailsPlatz 3: Semantic Scholar
Gratis
Für: Anyone who wants to pay nothing
Semantic Scholar is a search engine for scientific papers that is entirely free, with no paid plans, built by the nonprofit Allen Institute for AI. It indexes more than 200 million papers from all fields of science, and a free account adds a library, email alerts and Research Feeds that recommend new papers. It is third because its AI does less than the two above: the short TLDR summaries cover only computer science, biology and medicine, the Semantic Reader is in beta and covers mostly arXiv papers, and Ask This Paper works on a limited set of papers. There is no smartphone app; the site is designed to be used in mobile browsers.

Behalten oder bauen
Könntest du es selbst bauen?
There is no plain version of a research tool. It is a library of papers and sources first, and a model that reads them second. You have neither.

Wie macht ToolGPA das Ranking der KI-Recherche-Tools?
Nach dem, was die eigenen Seiten jedes Tools zeigen (Preis, Gratis-Plan, Plattformen, Funktionen und Grenzen), und nach dem, was Leute in öffentlichen Bewertungen und Diskussionen darüber sagen. Nicht nach eigenen Tests. Platz 1 geht an das Tool, das zu den meisten Leuten passt, und Platz 2 und 3 an die beste Wahl für die Leser, die dabei außen vor bleiben.
