Translating a deck by hand means opening every slide, every table and every notes pane, one by one. For 60 slides in three languages, that is the whole afternoon.
The faster way is to send the whole file, say what you need, and get a PowerPoint back with the same design and the new language.
Which option should you use?
| Good for | Where it stops | |
|---|---|---|
| AI Glot | Long decks, several languages, a glossary that must hold, decks you update often | Not needed for a five-slide deck you will never reuse |
| DeepL | One file, quickly. It takes PowerPoint files up to 30 MB | One deck at a time, no plan to read first, and a glossary that swaps terms without understanding why they are fixed |
| PowerPoint’s built-in translate | A few text boxes with Translate Selection, or a translated copy of the whole deck with Copilot | Selection is a copying job, the whole deck needs Copilot, and Microsoft’s pages describe no glossary or scope rules |
| ChatGPT, Claude or another assistant | A few slides’ worth of text | You paste text out and back in, and carry your glossary into every chat. It cannot rebuild a deck with your design. A long deck uses up your usage limit |
| An agency or a freelancer | A keynote that sells your company | Slow, priced per word, and you still prepare the file |
Have a person review the deck that goes to the board or to a customer. AI Glot gives them a finished first pass, so their time goes into the words and not into the file.
Why AI Glot fits a deck
- PowerPoint in, PowerPoint out. Slide text, tables and speaker notes are translated and written into the same shapes.
- The design stays. Masters, layouts, themes, images and animations are not rewritten.
- Slides, notes, or both. You choose in one sentence, and the plan lists what it will touch.
- The same words on every slide. A glossary keeps the product name and the tagline identical from slide 3 to slide 30, and in the next deck too.
- A plan before any spend.

The one thing to check: length
Translated text is often longer than English, and AI Glot does not resize your boxes. German is the usual culprit. So the check after translating is simple: flip through the deck in slide sorter view and look for a title that wraps onto a third line or a bullet that runs past its box. Shorten that line, or ask for a shorter wording when you describe the job.
How to do it, step by step
1. Try a file for free. The PowerPoint translator needs no account and takes files up to 2 MB and 5,000 words.
2. Upload the deck in the app. An old .ppt file needs to be saved as .pptx in PowerPoint first.
3. Say what you need.
Translate the slides and the speaker notes into French.
Leave slide 1 and the last slide, the legal notice, in English.This sentence decides what gets translated. A rule about wording, such as “keep the product name in English” or “use short phrases that fit a slide”, goes into the second box at approval, because it is applied to each text block as it is written.
4. Add your glossary. Product names, your tagline, the word you use for “customer”. How to build a glossary.
5. Read the plan. It lists slides, languages and cost. Correct anything in a sentence.
6. Choose Lite or Standard.
Lite is about three times more words per credit and faster: right for an internal briefing or a training deck. Standard is for the deck a client will see. One credit is one word in Standard.
7. Approve and download.
One deck, several languages
The file names are an example. Each language is its own deck, with the same slide order as your original, so a translated deck always matches the English one slide for slide.
Three ways to run it
In the app is the path above.
With your AI agent: connect AI Glot as an MCP server. The agent uploads the deck, writes the plan, updates your glossary and downloads the result, inside the conversation you already have.
With the API or the command line: to translate every training deck as it is updated, or to build translation into your sales tools. See the API documentation.
Check the result
Open the deck in slide sorter view and scroll. Then open the notes of two slides. Keep the original deck until someone who speaks the language has looked at the slides that matter most.
To see what the plan says about your own deck, the free PowerPoint translator will read it without an account, and a free account comes with credits to run a real file. Pricing lists what a larger volume costs.
The limits quoted here are the ones in force when this was written: 30 MB per PowerPoint file, and 2 MB and 5,000 words in the free tool. DeepL’s limit comes from its own documentation. File names and slide counts in the diagrams are examples. Your plan shows the real figures for your own deck, and it is free to read.
