About the author
Jan Śliwa
I build SumizAI, the AI notes app, and I publish everything on this site, the blog included.
SumizAI is sold by 10UP Jan Śliwa, a sole proprietorship registered in Poland (CEIDG). That is me: the same name you see on the invoice, in the terms of service and in the privacy policy. When an article here says how the app files a note or what it sends to your AI provider, I am the one answering for it.
The articles describe what the app does today, checked against its code. If something in them is out of date, write to contact@sumizai.com and I will fix the page.
They cover one thing from many sides: how a chat with Claude or GPT becomes a Markdown note, how a vault's table of contents fills itself, what happens to duplicates, and how the .md files leave the app as a ZIP, a PDF or a PowerPoint deck. If you are weighing SumizAI as an Obsidian alternative, that comparison is the best place to start. Short version? Read the AI notes app overview.
