AI Resumma vs ChatPDF

AI Resumma

Two jobs in one tool — shortening documents and translating them — with credits that do not expire, which suits someone who processes a stack of files twice a year rather than daily. Seven dollars for 70 credits is a low bar to entry and there is no subscription to cancel. Against that: the company named in the terms was registered in the UK only in April 2026, and the free use advertised in the header does not appear as a tier on the plan page.

Pros

• +Accepts DOCX, PDF and PowerPoint files plus web links, not just pasted text
• +Translation across more than twenty languages, including text inside images
• +Credits do not expire, so occasional use is not penalised
• +API access included from the 28.90 dollar pack upward
• +Downloadable summaries rather than screen-only output

Cons

• −The operating company named in the terms was incorporated only in April 2026
• −The advertised free use does not appear as a tier on the plan page
• −Credits are charged per 1,000 characters or per 100 KB of file, so the price of a document depends on its length
• −The two cheapest packs do not include API access or priority processing

ChatPDF

The quickest way to interrogate one long PDF without building retrieval yourself, and the page-level citations are what keep it honest. But ChatGPT and Claude now read PDFs natively, so ChatPDF only earns its subscription if you need those citations, the multi-file view, or the API.

Pros

• +answers cite specific pages, so you can check them instead of trusting them
• +handles Word, PowerPoint, Markdown and text files, not only PDF
• +REST API supports streaming and multi-turn conversations
• +free tier works with no account and no card

Cons

• −two documents a day on free runs out fast during real research
• −Plus pricing is not published anywhere on the site
• −no team plan, SSO or shared document library
• −hard per-file limit of 2,000 pages or 32 MB
