ChatGPT, Claude and scans

Translating scans with ChatGPT or Claude: where it breaks

A chat model reads a photo of a document well and translates it decently. What comes back is text. The tables, the stamps, the signatures and the page itself are yours to rebuild.

What a chat model does well

It reads clear scans, copes with mixed languages and, with a good prompt, gives a solid first draft. For understanding a letter or translating one paragraph, a chat is often all you need.

Where it breaks on documents

The answer is text or Markdown, not the page. Tables are flattened or re-drawn as Markdown, stamps and signatures are described or dropped, and on a long multi-page PDF a chat can shorten or skip parts unless you go page by page. Consistent terms across a batch depend on you pasting the same instructions every time.

For a client deliverable that means someone still rebuilds the layout by hand, which is the slowest part of working with scans.

When a chat is enough

  • You need to understand a document, not hand it over.
  • One paragraph or a short plain letter without tables.
  • Personal use, where nobody will judge the layout.

Questions

Is ChatsControl just ChatGPT with a wrapper?

It uses language models for recognition and translation, like a chat does. The difference is everything around them: laying the translation back onto the page, keeping tables and stamps, a glossary and a self-check pass, and an editor on the scan.

Can I keep my own prompt?

Yes. Before translating you can set the domain, audience, tone and preferred terms, and they are applied to the whole document.
