Alai

Alai is a Y Combinator-backed AI presentation design tool that generates decks, infographics, and social posts while maintaining brand consistency across everything a team creates. Users build a design system from their own brand assets or pre-built templates, then generate multiple content formats — presentations, carousels, posters, social posts — with prompt-based AI editing plus manual controls when precision matters, and consistency is applied automatically across a project rather than needing to be re-set each time. Utility tools include PDF-to-PPT conversion and automatic deck "prettification" for existing, unstyled presentations. Exact pricing isn't shown on the homepage — the site references a separate pricing page and a direct founder contact email — but a functioning app (app.getalai.com) and testimonials from users at companies including Blackstone point to real, active use. Good fit for a team or individual that wants on-brand presentations generated automatically rather than manually re-applying colors and fonts to every new slide deck.
