What SumizAI is
A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.
A vault is a directory holding base.md, a generated table of contents up to six levels deep, and a notes/ folder with one .md file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.
The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

Where they differ
- Haloon is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a
.mdfile with a title, a place inbase.mdand a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI. - Haloon is paid software. Compare the two numbers directly: SumizAI is one dollar a month, one plan, and your AI provider bills you separately for the model you chose.
- AlternativeTo's description of Haloon does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard
.mdfiles to a folder you picked, and an unpaid account can still export all of them. - Haloon runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
- Haloon generates images. SumizAI does not — it writes text notes, and exports them as PDF or a PowerPoint deck.
- Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.

Reasons to pick SumizAI
- the notes you want already exist inside conversations with an AI model
- you want the filing — title, chapter, duplicate check — to happen without you

.mdfiles in a folder you picked - you would rather pay your AI provider directly than have a note app resell the model
