# SumizAI Blog

- [Why is SumizAI different from every other note editor?](https://sumizai.com/blog/why-sumizai-is-different-from-other-note-editors.html): A note editor gives you an empty page. SumizAI writes the note, files it in a chapter, checks it against what you already wrote, and saves a plain .md file.
- [How do you actually work with SumizAI day to day?](https://sumizai.com/blog/how-to-work-with-sumizai.html): Set up a vault, connect a provider key, ask questions, and let notes file themselves. The full working rhythm, from the first question to the exported deck.
- [What is a vault, and why is it a boundary?](https://sumizai.com/blog/what-is-a-vault-in-sumizai.html): A vault is not a folder with a nicer name. It is the edge of what the model can see, the owner of your table of contents, and the unit you export.
- [How does a chat answer become a note?](https://sumizai.com/blog/how-a-chat-answer-becomes-a-note.html): The pipeline, step by step: the answer streams in, a draft is generated, a chapter is chosen, duplicates are checked, and a Markdown file is written.
- [How does the table of contents file your notes?](https://sumizai.com/blog/how-the-table-of-contents-works.html): A tree of chapters up to six levels deep, a model that picks by number rather than by name, and a rebuild that lays the whole thing out again.
- [How does SumizAI stop your library filling with near-duplicates?](https://sumizai.com/blog/how-sumizai-handles-duplicate-notes.html): Candidates from full-text and trigram search, a second model scoring the match from 0 to 1, three vault modes, and a merge that only ever appends.
- [How do notes link to each other, and what links back?](https://sumizai.com/blog/links-between-notes-and-backlinks.html): Links live in the note text as ordinary Markdown links to real files. The model may only point at filenames it was given, and each note lists what points back.
- [What does SumizAI search when you search?](https://sumizai.com/blog/how-search-works-in-sumizai.html): Title, summary, body and the original question and answer, weighted, diacritics-insensitive, returning the matching fragment with the phrase highlighted.
- [Where does SumizAI store your notes?](https://sumizai.com/blog/where-sumizai-stores-your-notes.html): Plain .md files in a folder you choose, one directory per vault, base.md for the index and notes/ for the notes. The database is only an index.
- [Which AI models does SumizAI work with?](https://sumizai.com/blog/which-ai-models-sumizai-works-with.html): Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — always with your own API key, and the model list fetched from the provider.
- [How do you turn a vault into a PDF or a PowerPoint deck?](https://sumizai.com/blog/export-notes-to-pdf-and-powerpoint.html): A vault exports as a PDF at summary or full detail, or as a .pptx deck in table-of-contents order, with fifteen slide themes in three families.
- [How does SumizAI compare with Notion, Obsidian and a chat window?](https://sumizai.com/blog/sumizai-vs-notion-obsidian-and-chatgpt.html): An honest comparison: what each tool is actually for, where SumizAI overlaps, where it does not compete at all, and when you should use two of them together.
- [How do students and researchers use SumizAI?](https://sumizai.com/blog/sumizai-for-students-and-researchers.html): Vaults per subject, questions that produce revisable notes, a table of contents that becomes a syllabus, and a PDF you generate instead of a night you lose.
- [What does SumizAI do for developers?](https://sumizai.com/blog/sumizai-for-developers.html): Architecture decisions, debugging sessions and trade-offs become searchable Markdown next to your code — with the original reasoning kept underneath, unedited.
- [What does one dollar a month actually buy?](https://sumizai.com/blog/what-one-dollar-a-month-buys.html): Seven days free with no card, then one dollar a month for a single plan. You bring your own AI key, and an unpaid account can still read and export its notes.
- [What is Markdown, and why does it matter?](https://sumizai.com/blog/markdown.html): Markdown explained from first principles to expert detail: syntax, flavors, rendering, and why it became the backbone of modern software.
