Presenton

Based on the available evidence, Presenton looks worth considering, but the case is stronger for clear positioning than for large-scale proof of usability. The recurring claim across sources is consistent: it is open source, can run locally or self-hosted, supports multiple LLM providers, and exports editable PPTX/PDF. It is not a general design suite like Canva, and not just an image-only slide toy; a better comparison is an open-source, self-hostable alternative to Gamma or Beautiful.ai for producing presentation drafts.

Its practical value is speeding up the path from prompt or source document to a first draft deck. Multiple X posts and two Zhihu articles repeat the same core capabilities: generate slides from prompts/docs, connect to OpenAI/Anthropic/Gemini/OpenRouter, run locally, and export presentations. For evidence quality, the “proof of attention” mainly comes from repost-heavy X threads, GitHub-star mentions, and list-style “Gamma alternative” posts. That shows strong interest.
