Questions
Frequently asked questions
Everything about Vaults, merging, ownership and your Markdown files.
What is SumizAI?
SumizAI is an intelligent workspace — your second brain, powered by intelligence. It transforms your conversations with Claude or GPT into a structured, permanent library of clean Markdown notes, instead of a chat history you'll never open again.
How is SumizAI different from a normal AI chat?
Most AI tools leave your best ideas buried in a chat log. SumizAI distills every interaction into professional Markdown notes, groups them by topic inside Smart Vaults, generates tables of contents and summaries, and links related notes automatically. You build knowledge instead of a transcript.

No lock-in. SumizAI uses standard .md files stored locally. Your data belongs to you — open it in SumizAI, or in any other tool, forever. Own your thoughts. Own your files.

About SumizAI — AI second brain and Markdown knowledge workspace
SumizAI (sumizai.com) is an AI second brain and intelligent knowledge workspace that converts AI chats into Markdown notes. Every conversation with Claude or GPT is distilled automatically into a clean, professional note, filed into Smart Vaults and enriched with auto-generated tables of contents, auto-summaries and auto-linking wiki-links between related ideas.
Where a chat log forgets, SumizAI compounds. The Anti-Mess Merge detects similar topics and lets you merge new insights into an existing note instead of duplicating it, so a personal knowledge management system built with SumizAI stays readable after the thousandth conversation. Context-aware intelligence then reads your entire Vault, answering from your data, your projects and your history.
Because SumizAI writes standard .md files stored locally, there is no vendor lock-in: your notes open in SumizAI or any other Markdown editor, forever. Export any Vault to a professional PDF or PowerPoint deck in seconds. Developers, researchers, students and creators use SumizAI as the bridge between a fleeting thought and a structured future.
