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
- AlternativeTo's description of Inkwell Markdown Editor does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them.
- Inkwell Markdown Editor 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.
- Both keep Markdown, which makes moving between them mostly a matter of copying files. In SumizAI a vault is a directory holding
base.md— a generated table of contents — and anotes/folder with one.mdfile per note. - AlternativeTo lists no mobile version of Inkwell Markdown Editor. SumizAI runs on macOS, Windows, iOS and Android.

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