Kittl vs PosterGen

Kittl is a web-based design platform for creating illustrations, presentations, and branded graphics. Its tools include templates, a brand kit, background removal, image upscaling, vectorization, text effects, mockups, and an infinite canvas. AI features include image, vector, and video generation, plus a creative agent. Real-time collaboration is available, and sellers can create Shopify and Etsy banners and Etsy listings. The free plan is free forever and includes five projects, 100 one-time AI tokens, and access to more than one million photos, graphics, and fonts. It is for personal use only, without commercial rights; free users can preview most Pro features with light usage limits. Paid plans add premium assets, high-resolution and vector exports, more AI tokens, larger project limits, and commercial licensing. Pro is $168.00 per year and Expert is $468.00 per year, both with annual billing. Kittl runs on the web; no desktop or mobile app is listed.

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.
