That is our reading of the record. For AlternativeTo's own wording, see its page for Google Gemini — the facts above were read on 2026-08-16.

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.

Side by side

Where they differ

• This is not really a competitor: Gemini is one of the seven providers SumizAI connects to. You put your own Gemini API key into SumizAI and keep using the same model — the difference is what happens to the answer. In Google Gemini it stays in a conversation; in SumizAI the answers worth keeping become Markdown files in a folder you chose, titled, filed into a table of contents and checked against what is already there. You pay Gemini directly either way; SumizAI adds a dollar a month and no markup on the model.
• Google Gemini is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
• AlternativeTo's description of Google Gemini does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard .md files to a folder you picked, and an unpaid account can still export all of them.
• Google Gemini's description mentions voice. SumizAI has no voice input and no transcription — the input is a typed conversation.
• Google Gemini 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.
• Google Gemini generates images. SumizAI does not — it writes text notes, and exports them as PDF or a PowerPoint deck.
