Short answer

An AI presentation maker for teachers should meet two conditions: the slides must end up somewhere you can freely edit (because no generated deck survives contact with a real class unchanged), and the free tier must cover normal teaching use. Slides by DocGPT.ai does both. It generates a complete Google Slides deck from a topic — you choose the number of slides, the tone, and the language (40+ supported), and you can paste your own lesson plan as source content so the deck follows your structure and timing. The free plan includes 10 AI presentations a month with no credit card, which covers a couple of new lesson decks a week; paid plans start at $14.99/mo if you need more — see pricing.

The path: install the add-on → Extensions → AI GPT for Slides → Start → topic + lesson plan → generate → fact-check and adapt in Google Slides.

Slides by DocGPT.ai is part of the DocGPT.ai suite used by 500,000+ users.

How it works

1. Install the add-on from the Google Workspace Marketplace. It works inside the Google Slides you already use with Google Classroom and your school’s Workspace.
2. Open the generator: Extensions → AI GPT for Slides → Start in any Google Slides file.
3. Describe the lesson. Enter the topic, choose how many slides (around 12 works for a 45-minute lesson), pick a friendly, age-appropriate tone, and select the language.
4. Paste your lesson plan as source content. Timings, key concepts, the quiz you want, the homework task — the AI builds the deck around your plan rather than a generic explainer.
5. Generate, verify, adapt. The deck is native Google Slides: fix anything the AI got wrong, adjust reading level, add your images and diagrams, and reuse the deck year after year.

Step-by-step guides: create a presentation from a topic and create slides from your own text.

Worked example: a 45-minute grade 8 science lesson

Settings to use in the add-on:

• Slides: 12
• Tone: friendly and educational
• Language: English (or any of 40+)
• Topic: Photosynthesis — 45-minute lesson for grade 8 science

Paste this into the source-content field, adapted to your own lesson plan:

Class: grade 8 science, one 45-minute lesson on photosynthesis.

Build the deck around this lesson plan:
- Starter (5 min): one question slide — "What do plants eat?"
- Core concepts (20 min): chlorophyll and where photosynthesis
  happens; inputs and outputs (carbon dioxide + water + light →
  glucose + oxygen); why it matters for the food chain.
- Worked example (10 min): the word equation, then the balanced
  chemical equation, one slide each.
- Check for understanding (5 min): 3 quiz questions with answers
  on the following slide.
- Recap + homework (5 min): one-slide summary and the homework task:
  label a leaf diagram.

Keep the language at a grade 8 reading level. One idea per slide.

The generated deck lands as normal Google Slides: a title slide, the starter question, concept slides with bullets and image+text layouts, the quiz, and the recap. Your editing pass is the professional part — check every factual claim, swap in the diagram your curriculum uses, and tune the quiz to what this class actually struggled with last week.

Language classes: generate the deck in the target language

Because Slides by DocGPT.ai generates in 40+ languages, language teachers get a second workflow for free: write the lesson plan in your language, and generate the deck in the target language. A Spanish teacher can produce an A2-level deck on daily routines in Spanish; a French teacher can generate the same cultural topic once in French for the class and once in English for a parents’ evening. The language selector applies to the whole deck, and since the output is editable Google Slides, you can adjust vocabulary to exactly the level your class has covered.

Verify before you teach: the honest note

AI-generated educational content must be fact-checked by the teacher — no exceptions. Slides by DocGPT.ai is excellent at structure, pacing, and age-appropriate slide copy, but like any AI it can state facts with confidence that are subtly wrong, outdated, or misaligned with how your curriculum defines a term. Dates, equations, definitions, and quiz answers deserve a line-by-line check before the deck reaches students. The time math still works strongly in your favor: verifying and adapting a complete draft takes a fraction of the time building a deck from a blank slide does — but the verification pass is part of the job, not optional.

Frequently Asked Questions

Is there a free AI presentation maker for teachers?

Yes. Slides by DocGPT.ai has a free plan with 10 AI presentations per month and no credit card required — enough for a couple of new lesson decks a week. Paid plans start at $14.99/mo if you need more.

Can it create lesson slides in other languages?

Yes. You can generate the deck in any of 40+ languages, which is especially useful for language classes: write the lesson plan in your language and generate the slides in the target language, then edit vocabulary to your class’s level in Google Slides.

Can I trust AI-generated facts in lesson slides?

Treat the deck as a draft, not a source of truth. Check dates, definitions, equations, and quiz answers against your curriculum before teaching. The add-on saves the structuring and writing time; the teacher’s verification pass is still essential.
