A resume that does things a PDF never could.
Follio is a web app for job seekers and professionals to build one living profile and share it as a resume, portfolio, or quick snapshot through a single link, with clean formatting, viewer-adaptive presentation, and AI assistance that helps answer recruiter questions and suggest skills based on market trends.
More than a document
Your living resume that works for you.
It tracks the market and tells you which hot skills you’re missing.
You build it once. Every viewer reads it their way.
It answers questions — even when you are not there.
It plugs into where your work already lives.
One link to share — public or private, fully under your control.
It catches the mistakes that quietly cost you interviews.
Stored as clean data, so machines read it perfectly.
