Hey everyone,
What if you could build professional PowerPoint presentations, complete with custom layouts, grids, and visual assets, without ever opening Microsoft PowerPoint?
Meet PowerPoint Skills
We have embedded PowerPoint capabilities directly into Alter. Simply add the PPTX skill to your workspace, provide your templates or instructions, and let Alter handle the creation, formatting, and export process.
How It Works
Setup: Create a workspace and enable the PPTX skill.
(Recommended) Prepare: Drop your presentation templates into your workspace folder.
Plan: Use Plan Mode to define your slide structure. Alter will refine the plan with you to ensure the output matches your vision.
Create: Instruct Alter to build your slides.
Review & Export: Alter generates the PowerPoint file, PDFs, and preview images directly in your chat. You can review the visual output inline, and open the files in PowerPoint or Keynote with a single click.
Example prompt (used in the video)
Make a nice logo grid slide with the AI providers shown on this website about Alter
Make sure
1. Respect logo aspect ratio
2. Have consistency in term of width
3. Produce both the PPTX and PDF for review
4. Use Template.PPTX for colors, font and design principles
5. Create also JPG version of the slide for review
Use the logo images served on Alterhq.com homepage
Pro-Tips: Reviewing and Refining Your Slides
Don't just stop at the first draft. Leverage Alter to perfect your deck:
Inline Review: Use the generated preview images to instantly check alignment and visual hierarchy without leaving the chat.
Suggest Modifications: Found a slide that needs a tweak? Simply ask: "Can you adjust the layout on slide 3 to be more balanced?" or "Change the font size of the titles to be larger."
Grammatical Fixes: You can ask Alter to proofread your entire presentation. Try: "Review the text in the deck for grammatical errors and improve the overall tone to be more professional."
Iterative Improvements: If you need to change imagery or data, just point to the specific slide and tell Alter what to swap out.
What presentation use case should we solve next? Let us know!
