The Letter AI Deck Generator leverages AI to create polished, structured slide presentations tailored to your topic, audience, and brand. In just a few steps, you can go from a simple description to a fully generated deck — ready to review, refine, and publish.
When to use Slides: The Deck Generator is ideal for creating sales pitch decks, onboarding presentations, product overviews, training materials, or any structured presentation where you want AI to do the heavy lifting based on your content library and inputs.
Who should create them: Sales, marketing, and enablement teams who need to produce consistent, on-brand presentations at scale. Owners can also upload branded templates to ensure all generated decks reflect company standards.
How to create
Start by clicking the Create New Content icon, then select New Content. Then, select Slides. There are three stages when creating slides: Define Needs, Review Content, and Publish Content.
01 Define Needs
01 Define Needs
This stage involves describing what you want to create and configuring your generation settings.
Topic: Give your deck a clear, descriptive topic. This is the core subject the AI will build around.
Description: Provide additional context about what the deck should cover
Template: Select a Google Slides or PowerPoint template to define the visual style of your deck. You'll see both default templates and any branded templates your organization has uploaded in Team Settings.
Desired Number of Slides: Use the slider to set how many slides you'd like generated (between 1 and 20).
Audiences (Optional): Target the deck to a specific audience segment.
Primary Language: Defaults to English (United States). Note: Users can translate the deck into any supported language when they access it from the content library.
Reference Files: Select existing content from your Letter AI library for the AI to use as source material when generating slides. You can also add or remove files using the link at the bottom of the list.
When you're ready, click Generate Content to move to the next stage.
02 Review Content
02 Review Content
Once the AI has generated your deck, you'll be brought into the slide review experience where you can preview each slide and make refinements before publishing.
The left panel shows a thumbnail list of all generated slides with their titles. Click any slide to preview it in the main area. Each slide has a Regenerate Slide button in the lower right corner.
Clicking Regenerate Slide opens a Write a custom prompt modal where you can provide specific instructions for how to revise that individual slide (e.g. "Redesign this slide into a modern, minimal enterprise SaaS style. Use a clean grid layout with four evenly spaced feature cards."). Click Generate to apply.
Once you're happy with the deck, click Finalize to proceed to Publish.
03 Publish Content
03 Publish Content
This is the final step that involves publishing your deck to be available in the Public Library (if you're an Owner, Admin, or Content Creator) or in your personal Library (if you're a Manager or User). Here's an overview of this stage:
Users & Managers:
Preview the asset. View a complete draft of the deck by clicking the Preview Asset button next to the Publish button on the lower right hand side of the page.
Edit the Title or Description: If you want to make any changes to the Title or Description, simply click the pencil icon next to the item you want to edit.
Share Content (internal only): If there are members on your team you'd like to share the deck with, select them here.
Assign Tags: Choose tags that correspond to the deck (this makes finding the content easier).
Thumbnail image: This is the image that shows up in your personal library.
Owners, Admins, and Creators:
Provide Access: Determine who can view the deck by assigning it to specific access groups.
Assign Tags: Choose tags that correspond to the deck.
Request Approval: If approvals are enabled, it will require the author to get approval before publishing.
Content Owner: Choose the person who will get notified of content expiration and feedback on the content.
Expiration Date: Use this if the deck should have a set date in which it will no longer be accessible.
Priority Source: Toggle this feature on if you want the AI Agent to prioritize using this deck as a priority source.
Show completion time: This is displayed to the user upon opening the deck, and can either be the AI-generated suggested completion time or a manually overridden value.
Competencies: If this deck relates to any specific competencies, add them here.
Once you've reviewed the above sections, click the Publish button on the lower right hand side of the page to make the deck available to your selected audience(s).
Add Templates (Owners only)
Add Templates (Owners only)
Owners can upload organization-wide branded templates that appear in the template selector for all users. This ensures every generated deck aligns with your company's brand standards.
To manage templates:
Go to Settings > Team Settings > Branding > Document templates.
Drag and drop a file into the upload area, or click Select file to browse.
Supported formats: Word, Google Docs, Slides, PowerPoint, Excel.
Click Save.
Once uploaded, the template will appear in the template selector during deck generation for everyone on your team. You can see all saved templates listed below the upload area, and remove any by clicking the × next to the template name.
Tips
Tips
The more specific your topic and description, the better the AI output. Include details about your audience, goals, or key points you want covered.
Adding relevant reference files grounds the AI in your actual product knowledge and company content, leading to more accurate and on-brand slides.
Use the custom prompt in Regenerate Slide to fine-tune individual slides without having to regenerate the entire deck.
Owners should keep branded templates up to date in Team Settings as branding evolves to ensure consistency across all generated decks.
