What our research says

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 site is anonymous, with no company, address or jurisdiction anywhere, and the free tier advertised in the header does not appear on the plan page at all.

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

  • No company name, address or country is published anywhere on the site
  • The advertised free use does not appear as a tier on the plan page
  • Credit cost per request varies by tool, so the real price per document is unclear up front
  • 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
