Habr AI has published a review of nine services for AI search and document work. The list includes BotHub, Perplexity, DuckDuckGo, Brave, ChatPDF, GigaChat, Felo AI, iAsk and Komo. The review shows the market splitting into three niches: private web search, deep research with citations, and targeted analysis of PDF, DOCX and other files uploaded directly into the chat.

Habr AI has published a review of nine AI tools for finding information on the web and in PDFs. Rather than just returning links, they assemble a ready-made answer from the web, uploaded documents and office files.
Which AI tools can handle both PDFs and web search?
Habr AI compared Perplexity, GigaChat, ChatPDF, BotHub, Brave Search, Felo AI, iAsk, Komo and DuckDuckGo. All of them let you ask a question in plain language, and the service decides where to look for the answer: on the web, in an uploaded document, or across several sources at once.
