For most everyday users, ChatPDF wins on sheer simplicity and a generous free tier — it's the easiest way to chat with a single PDF on any device. Elicit is far more powerful for serious academic research, with a massive paper database and structured data extraction, but its credit-based pricing and steeper learning curve make it overkill for casual use. The single biggest difference: ChatPDF is a quick PDF chat tool; Elicit is a full research assistant for systematic literature reviews.

Common questions
Yes, for a single paper ChatPDF is faster and easier. Just upload the PDF and ask for a summary. Elicit can also summarize, but you have to search for the paper first, and its interface is more complex.
Both work in a mobile web browser, but neither has a dedicated mobile app. ChatPDF's simpler interface works better on a small screen. Elicit's data extraction tables are hard to use on a phone.
Elicit is far better. It can search across millions of papers, filter by study type, and extract structured data into a table. ChatPDF can only handle one PDF at a time (or a folder of a few PDFs) with no structured output.
Probably not. If you're not doing academic research, the credit cost and learning curve aren't justified. ChatPDF's free tier will cover most casual needs like summarizing contracts, reports, or articles.
ChatPDF can handle scanned PDFs if they have text layers (OCR). Elicit relies on the paper's metadata and full text from its database, so scanned PDFs you upload may not extract well. Neither is ideal for image-heavy documents.
ChatPDF is the easiest way to chat with any PDF for free; Elicit is the heavy-duty research assistant for serious literature reviews.
If you just want to ask questions about a PDF without any fuss, start with ChatPDF — it's free, fast, and works in your browser. If you're diving deep into academic research and need to synthesize dozens of papers, invest the time to learn Elicit; it's the more powerful tool for that job.
