PPT Master alternatives (2026)
PPT Master: The best free way to get an agent to produce PowerPoint people can actually edit — bring a strong model and skip the relay sponsors.
Its Catch: The author says it outright: the model sets the ceiling and you will not get a finished deck in one shot — the recommendation is a long-context frontier model plus a paid image model, and cheaper models leave more cleanup.
Below: 3 free or free-tier tools from the same category (document, PDF and typesetting tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.
Free / OSS · Apache-2.0 · 56.7k GitHub stars
VerdictApache-2.0 typesetter. Free CLI forever; use when docs should compile fast and the cloud editor is optional.
Catchtypst.app collaborative cloud is a separate product with its own free/paid seats — the compiler CLI here is the OSS gem. Vs Pandoc/Quarto and vs LaTeX: smaller package ecosystem and different mental model; migration is a rewrite, not a flag. Not a slide tool.
Free / OSS · GPL-3.0 · 46.9k GitHub stars
VerdictGPL-3 self-hosted DMS. Use for OCR + searchable archives; not an agent memory substitute.
CatchVs Notion/Drive dumps: this is a document archive appliance, not a knowledge wiki or agent memory layer. GPL-3 copyleft for modifications; OCR/ML quality depends on language packs and scanner hygiene; public docs/demo endpoints may be WAF-gated from some networks — use the GitHub tree and Compose files as source of truth.
Free / OSS · OSS/MIT · 13.3k GitHub stars
VerdictThe default way to add HTML or Office-to-PDF to any backend — keep it on your private network.
CatchIt converts to PDF, not from it: it won't turn a PDF back into Word or text. It is a service you run next to your app, not a library you import, so you deploy, scale and secure the container yourself, and the bundled Chromium and LibreOffice make it a heavy image. Keep it off the public internet: its URL route fetches whatever address it is sent.
