How to translate Google Slides with AI

Translate Slides™ with AI GPT is a separate sister add-on from DocGPT.ai that translates an existing Google Slides presentation into another language. Unlike the generator in Slides AI by DocGPT, it does not create new content: it takes the deck you already have and translates its text in place, keeping the layout and the formatting.

See the Translate Slides landing page for pricing and the install link.

When to use it

  • You built and polished a deck in one language and need the same deck in another.
  • You need several language versions of one master deck.
  • You received a deck in a language your audience does not read.
  • You present to a mixed audience and want each slide in two languages (use Keep original, see below).

If the deck does not exist yet, it is usually simpler to generate it directly in the target language: see Writing tones and languages.

How to translate a deck

  1. Install Translate Slides™ with AI GPT from the landing page and approve the permissions for the account you use with Google Slides.
  2. Open the presentation and choose Extensions → Translate Slides™ with AI GPT → Launch.
  3. Pick the language under Translate to (more than 100 languages).
  4. Choose What to translate:
    • This slide: the slide you are on;
    • Selected slides or text: select slides in the slide panel on the left, or text boxes, table cells or a few words on a slide, before you press Translate;
    • Whole presentation: every slide, one after another, with a progress bar and a Stop button.
  5. Choose the Result: Replace text (translate in place) or Keep original (a translated copy of each slide is added right after it, and your original slides stay as they are).
  6. Press Translate.

A new, empty presentation? The add-on offers Add a sample slide so you can try it on example text first.

What is translated

  • Text boxes and shapes, including shapes inside groups.
  • Tables, cell by cell.
  • Speaker notes (switch Speaker notes off to leave them as they are).
  • Text inside images, charts and word art is not translated.

What happens to formatting

  • Each paragraph is translated on its own, so bullets, numbering, alignment and line breaks stay.
  • Words with their own formatting keep it in the translation: a bold word, a coloured number or a link moves to the matching translated words.
  • Numbers, dates, URLs and email addresses are kept as they are.
  • Translations often run longer (German or French text is typically longer than English). With Fit longer text on, the font in a fixed text box is made a little smaller when the translation grows, never below 70% of the original size. Text boxes set to resize with their text are left to grow.
  • The result is still a normal Google Slides deck: fully editable, exportable to PPTX or PDF via File → Download.

More options

  • Rephrase instead of translate, in a chosen tone (Professional, Friendly, Persuasive and others).
  • Context for the AI: the audience, the region or whether to use a formal or informal “you”.
  • Glossary: one entry per line. A name on its own line (for example your product name) is never translated; term = translation always uses your translation.

Free plan and Premium

  • On the free plan you translate one slide at a time, and each translated slide uses one free credit. A slide without text uses none.
  • Premium translates the whole presentation (or several selected slides) in one go, adds Keep original copies and the glossary. Plans and prices are on the pricing page; Upgrade to Premium in the add-on’s menu shows them too.

Troubleshooting

  • The menu or the sidebar does not appear: you may be signed in to several Google accounts. Open the presentation in a window with only one account, then use Extensions again.
  • “Select slides in the slide panel…”: with Selected slides or text, select something in Slides first; clicking inside the add-on does not change the selection.
  • A slide was skipped: it had no text the add-on can edit (for example only images). Slides that could not be translated are listed after the run with Try again.
  • Paid but still on the free plan: use Talk to a human in the add-on’s menu and tell us the email you paid with.
