Slidely AI

Slidely AI is a Y Combinator-backed (S22) startup building an AI copilot that lives inside Microsoft PowerPoint. Instead of exporting to a web builder, users generate, redesign, reformat and proofread fully editable slides from a natural-language prompt, and the tool learns a company's existing fonts, colors and layouts so output looks on-brand rather than generic. Founded in 2022 by Apoorve Singhal and Nikhil Shah, the company targets consultants, corporate teams and students who live in PowerPoint and want to cut the time spent formatting decks.
