What it is, who it suits, its grades and the ten things to know first

The report card
Best for asking questions of PDFs
PDF.ai lets you chat with PDFs and parse them through an API. The free Hobby plan is 1 PDF with OCR on 2 pages per file, and the API on Ultimate is for non-commercial use only.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Pro is $10 a month billed yearly, the research middle. Ultimate is $20 per user, which is where the dearest tenth begins. |
| Free plan and trial | C | The Hobby plan is $0 for 1 PDF and 100 questions a month. That's one document at a time, so a normal reader outgrows it quickly. |
| Features | C | Chat with a PDF, OCR, chat with all PDFs, capture and ask, an API and a chatbot widget. The listing shows only 1 PDF on Hobby and OCR capped at 2 pages per file, but the core chat job is covered. |
| Ease of use | B | No store rating on record. Upload a PDF and ask: nothing to set up. |
| Platforms and integrations | B | Web and a browser extension, with an API. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who PDF.ai is for
- Fits if you ask questions of one PDF at a time
- Works for developers who want a PDF parsing API
Who it is not for
- Tight if you stay free: 1 PDF and OCR on 2 pages per file
- Watch out: the Ultimate plan's API is non-commercial only, and commercial use needs the credit add-on
- Watch out: the chatbot widget is a separate paid plan
- Watch out: monthly-billing prices weren't readable, and the pricing page would not load for us
Good to know
Good for
- People who want quick answers from long PDFs

Worth knowing
- Monthly-billing prices were not readable; the prices shown are those billed yearly.
- The Ultimate plan's API is for non-commercial use only; commercial use needs the credit add-on.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace PDF.ai you would be making an AI model, which you can rent by the request but not make. That is not a weekend's work, with an AI app builder or without one.
It costs $120 a year.
What you could make
- Documents: an app builder makes this well.
What you could not
- An AI model, which you can rent by the request but not make.
- A library of papers and sources to search.
- An API that other software can build on.
- Hooks into the device itself: widgets.
What this rests on. PDF.ai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
