PosterGen vs Ridvay

PosterGen generates academic posters from research paper PDFs, using a multi-agent language-model workflow to extract content, plan a narrative, arrange the layout, and apply styling. Its Parser Agent structures paper content, while the Curator Agent plans organization and visual placement. Layout and Balancer agents calculate spacing and column use, with the Balancer addressing overflow. Styling includes colors drawn from an affiliation logo, professional font choices, and keyword highlighting. Users can adjust layout, typography, color generation, visual asset sizing, and content optimization through configuration. A local web interface accepts a paper PDF and logos, lets users configure models and poster dimensions, and generates a PNG plus an editable PowerPoint file. Documented width-to-height ratios run from 1.4 to 2, and custom dimensions are supported. The project lists Windows, Linux, and macOS, but setup requires Python 3.11 and LibreOffice; the web interface also needs Node.js and configured API keys. Setup documents OpenAI, Anthropic, and Zhipu keys, with configurable service base URLs including Google. PosterGen is free and MIT-licensed; the license provides the software without warranty.

Ridvay Studio turns plain-language descriptions into editable posters, social posts, slides, thumbnails and multi-page designs such as decks, carousels and documents. Users can move, restyle or delete generated elements. The Recreate feature converts an uploaded screenshot, photo or old flyer into a design with editable text and layers. Brand kits store colors, fonts, logos and a brand voice for use during generation and refinement. Designs can be exported as PNG, SVG, PDF, PowerPoint, GIF or MP4, and shared through editable links. Free exports carry a small “Made with Ridvay” credit; paid plans remove it. A hosted MCP server can connect to clients including Claude, ChatGPT, Cursor and GitHub Copilot in VS Code, allowing agents to create or refine designs, export and share them, and update variables. The Free plan includes five AI designs and three AI images per day, plus unlimited manual designs and templates. Plus costs €5.99 a month. Ridvay has no mobile apps. The maker says chat messages and uploaded images may be processed by third-party AI providers depending on the selected model.
