How to Pick the Best AI‑Powered PPT Generator: A Hands‑On Comparison

1. Introduction

Many users want to generate PPTs with AI but are unsure which tool to choose. The author emphasizes that the most important step is not the tool itself but clarifying the presentation logic and preparing the necessary material before selecting a generator.

2. Preparation

2.1 Clarify the Idea

The author suggests asking key questions: Who is the audience? Should the deck be a simple concept explanation or an experience share for AI practitioners? What level of examples is needed? If no clear outline exists, let the AI produce a draft outline first, then refine it.

2.2 Gather Materials

For a PPT about context engineering, the author recommends using AI “DeepResearch” features (e.g., Qwen) to collect high‑quality references, then exporting them as Markdown via the MarkSnip Chrome extension or as PDF via PrintFriendly. Specific sources mentioned include LangChain’s Context Engineering guide and Manus’s AI Agent Context Engineering paper.

3. Tool Selection

3.1 Kimi PPT Assistant

Kimi, developed by the Moon Shadow team, generates PPT outlines and content from a user‑provided topic or full text. It accepts Word, PDF, and other formats as source material, offers template selection, and exports to common formats. The author notes the UI is consistent and the process feels like a human editing a slide deck.

3.2 Zhipu (智谱)

Zhipu’s tool (https://chat.z.ai/) does not generate an outline automatically, so users must embed the desired outline in the prompt. It creates PPTs by generating HTML code, which can be edited via natural language. The author highlights that adding speaker information works well and the final output can be streamed online.

3.3 Manus

Manus is a well‑known AI agent platform offering 300 free credits per day. Users upload material, provide a prompt, and select the “slide” function. The author encountered a markdown‑parsing issue, which was resolved by re‑uploading the content in Markdown format. The tool extracts key points, builds a framework, and generates downloadable PPT or PDF files.

3.4 Coze Space (扣子空间)

Coze Space (https://space.coze.cn/) lets users select a PPT template, provide reference material, title, and outline. If no outline is supplied, the system generates one automatically, which can then be edited before proceeding. The author feels the generated slides contain too much text and weak visual‑text coupling.

3.5 Gamma

Gamma (https://gamma.app/create) is a powerful AI presentation tool that generates content, auto‑formats layout, and supports one‑click export. Users can adjust text volume, language, visual style, and page count. The free tier limits output to ten slides and accepts only a single file upload.

4. Final Thoughts

The author’s overall experience shows AI‑generated PPTs are still immature. They work well for simple drafts or quick references, but for polished decks, a clear outline and well‑curated source material remain essential. Among the tested tools, Kimi, Manus, and Zhipu performed best, while traditional slide software has not yet adapted fully to AI workflows.

Future improvements in both AI models and dedicated presentation software are expected to raise the quality of AI‑generated slides.
