Introduction
FlashDocs provides a robust, easy-to-use API for generating Microsoft PowerPoints and Google Slides.
Why you should use FlashDocs: [1] use your existing, completely custom branding/slide themes, [2] generate all the content you need (text, images, tables, and charts), and [3] provide content generation instructions with various levels of control (prompt / per slide instructions / markdown / placeholder to value mapping).

Key Features
Seamless & Instant Custom Branding
Single API call to upload your slide template & formats. We automatically process all of your slide layouts so every slide generated through FlashDocs is on-brand. You can upload any slide deck template with any types of styles and all generated slides will follow the layouts.
- No hand-labelling required - single document upload API call. Our system automatically infers various placeholders and their generation instructions: text, image, logo, table, chart, etc.
Complete Content Control
FlashDocs provides a variety of ways you can define control the content generated - from unstructured prompts, to arbitrary markdown, and manually defined placeholder insertions.
- Prompt - provide an unstructured, string prompt with instructions on how to create your deck.
- Per Slide Content Instruction - In the outline parameter, you can provide unstructured string instructions for each slide in the deck. Ex: “Discuss the importance of document generation for our product, highlighting these 3 areas: A, B, C.”
- Per Slide Layout Instruction - In the outline parameter, you can provide unstructured string instructions for the slide layout. Ex: “3 step timeline from left to right with central step being largest.”
- Markdown - Provide full Markdown (including tables, images, nested lists, rich formatting, etc.) and FlashDocs will generate a slide in your custom layouts
- Tag Replacement - All objects in a slide (text, image, table, chart, etc.) can be replaced by providing a mapping from the object id (which you can see from a GET request) to the value you wish to insert.

High Level Idea of How FlashDocs Works
FlashDocs transforms an ordinary presentation (like Google Slides or PowerPoint) into a programmatic FlashDocs document complete with placeholders (for text, images, charts, etc.) that can be dynamically filled. In other words, we preserve brand styles, layouts, and design, but replace the core content with placeholder elements. When it’s time to create a new deck, FlashDocs automatically populates these placeholders with fresh, prompt-driven content—enabling programmatic deck creation.
Documents: Templates vs. Libraries
Library
A library is a (large) collection of slide layouts—think of it like your personal buffet of slides. When generating a deck from a library (via Generate Deck Request), FlashDocs’s recommendation system (using embeddings and vision models) identifies the most relevant slide(s) for your deck and then populates the placeholders with custom generated text and images based on your prompt.
Template
A template is a set of slides with some content hard-coded (i.e., not in placeholders) so it always remains the same. This is handy for scenarios like sales decks: the core slides remain unchanged, but placeholders for a client’s name, logo, or specific use cases get filled in automatically. The result is a consistently branded, partially dynamic deck.
Creating a Custom Deck
FlashDocs scours your library, picks the slides that best fit your needs, and auto-generates text for those slides. You end up with a handpicked deck that feels tailor-made to your audience—without you lifting a finger for design.
Creating a Deck from a Template
Every slide in the template is used (no picking and choosing), and FlashDocs automatically populates any placeholders according to your prompt. All non-placeholder content (like disclaimers, branding, or repeated text) remains exactly as it was in the original.
