We earn commission on every tool we feature. What that never buys is a position. We test first and rank second, and a tool that pays well can still finish last. How that works.
PDF and document software with AI bolted on. The question is whether the AI does anything you would miss.
Almost every document tool has shipped an AI assistant in the last two years. Most of them summarise a PDF and call it intelligence.
We are only interested in the AI features here, not the software underneath. If the assistant cannot answer a question about a long contract accurately, the rest is a PDF editor with a chat box.
Every tool on this page has a commercial relationship with us, and we earn if you buy through our links. That is why we rank the set we cover rather than claiming to rank the whole market. What the money never buys is a position: the highest payer here can and does finish last.
2 tools considered for this page. The leaderboard reports the wider market in full, including tools we earn nothing from.
AI research agent that answers from your own documents and sources rather than the open web.
PDF software with an AI assistant for document questions.
Nine tasks on paid licences. Output quality covers question answering across a 60 page contract we already know the answers to, summarising a dense technical document, and extracting structured data from a scanned form. Any confidently wrong answer about the contract scores that task zero, because in documents a plausible wrong answer is worse than no answer. Reliability repeats the same questions three times. Control tests whether you can constrain it to the document rather than its general knowledge. Value is cost per seat against how often the AI actually gets used. Workflow covers export fidelity and integrations. Support is one real question, timed.
Once scores are live this names a pick per case.
