Preparing Presentations with AI 2026: Gamma, PowerPoint Copilot, Google Slides and NotebookLM Compared
Preparing presentations with AI in 2026 is stuck between two extremes: on one side tools that produce a sleek draft from a single sentence, on the other side presentations that do not match the corporate template, are shallow in content and all look the same. The right use is between the two: the tool builds the skeleton and the first draft, and a person provides the message, the order and the final layout. This guide compares four tools honestly and explains how to solve the corporate template problem and how to write a good brief.
The price and feature information is dated September 2026 and changes quickly. Check the tools' current pages before deciding.
Four tools, four different jobs
| Tool | Best at | Weakness | Price note (September 2026) |
|---|---|---|---|
| Gamma | Fast, visually strong drafts from scratch, web-based sharing | Full faithfulness to the corporate PowerPoint template, layout shifts on export | 400 free credits (about 10 presentations), upper plans over 100 $ |
| PowerPoint Copilot | Drafts from company files with the corporate template, presentations from a Word document | Limited visual creativity, Turkish tone sometimes flat | With the Microsoft 365 Copilot licence, 21 to 30 $ per user |
| Google Slides (Gemini) | Single-slide generation inside Workspace, image creation, editing an existing deck | Does not produce a full deck, works slide by slide | Included in Business Standard and higher Workspace plans |
| NotebookLM | Content-focused, verifiable drafts from source documents | Low design quality, needs export and editing | Free, with a daily production limit |
The practical selection rule: if the source of the presentation is company documents, Copilot or NotebookLM. If the source is an idea, Gamma. If the team is already on Workspace, start with Slides. For details on the Microsoft environment, see the Copilot guide, and for NotebookLM the NotebookLM guide.
How is the corporate template problem solved?
The most common complaint is this: "The tool makes nice presentations, but they do not look like our template." There are three solutions:
- Teach the template to the tool: In Gamma a brand kit (colours, fonts, logo) is defined. PowerPoint Copilot uses the company's template file. In Slides the company theme must be selected.
- Separate content and design: Produce the content with ChatGPT, Claude or NotebookLM in the format "slide title and three bullet points", then place it in your own template. This is the flow that saves the most time, because the design is already ready.
- Let a person do the final layout: The tool's output is a draft. Fonts, alignment, image selection and slide order are checked by one person. A presentation that goes to a client does not go as it came out of the tool.
A good presentation brief: five elements
The quality of the tool is the quality of the brief. The request "prepare a sales presentation" produces the presentation everyone has seen. A good brief contains:
- Audience: Who will watch, what they know, what they will decide.
- A single main message: The one sentence that will stay in mind when the presentation ends.
- Scope: Number of slides, duration, language and tone.
- Sources: The proposal document, the report, the previous presentation. Without sources the tool makes things up.
- Prohibitions: Phrases not to use, figures not to show, competitor names.
Example: "Prepare a 12-slide, 15-minute presentation draft for a hospital purchasing committee, with the main message 'installation is complete in three weeks', based on the attached proposal document, with no price slide, in formal but plain Turkish. Add a 40-word speaker note for each slide."
Speaker notes and Q&A preparation
There are two outputs more valuable than the presentation itself: a speaker note for each slide, and the ten questions the audience might ask together with their answers. Both come out of the same brief with a single request. The speaker notes are translated into the presenter's own language, and the question list is reviewed by the team before the presentation. These two steps stop the presentation being "nice-looking but indefensible".
Where does a person take over?
- Message and order: which slide comes first, which argument is strongest.
- Figures: every number the tool writes is verified against its source.
- Image selection: real product and team photos instead of stock image cliches.
- The final read: structural repetition and the translated feel are cleaned up.
How to start
Preparing presentations is part of the department programs for marketing and sales teams: the team learns in one day to write briefs, prepare sources and fit the result into the corporate template, using its own real presentations. For the content, see the AI training for marketing teams, AI training for sales teams and content creation training pages. If you want to work one to one on your own presentations, the individual AI training session format is suitable.
Frequently Asked Questions
Which is the best tool for preparing presentations with AI?
There is no single answer. Gamma stands out for fast, sleek drafts from scratch, PowerPoint Copilot for working with the corporate template in the Microsoft environment, Gemini inside Slides for teams on Google Workspace, and NotebookLM for content-focused drafts from source documents.
Is Gamma free?
The free plan has 400 AI credits, which is roughly 10 full presentations. Paid plans are priced per user per month and the upper plans exceed 100 dollars. For corporate use, brand templates and team features are on the paid plans.
Does AI stay faithful to my corporate template?
Partly. PowerPoint Copilot improved template faithfulness with agent-based generation, released to general availability in April 2026. In Gamma a brand kit is defined. Even so, the final layout, font and colour check is a human job, and the output does not go straight to the client.
How is a good presentation brief written?
Five elements: the audience, the single main message of the presentation, the number of slides and duration, the source documents, the prohibitions. Instead of 'make a sales presentation', it is written like 'a 12-slide presentation for a hospital purchasing committee, with main message X, based on this proposal document'.
How do I teach the team to prepare presentations?
Instead of a tour of the tool, a workshop that works with the team's own real presentations. Writing briefs, preparing source documents, fitting into the corporate template and producing speaker notes are set up in one day. The department programs for marketing and sales teams include this.
