SumizAI vs Ollama App

What Ollama App is

AlternativeTo files Ollama App under AI Chatbot, Large Language Model (LLM). It is recorded as Free, Open Source — Apache-2.0, from International. It ships on Windows, Linux, Android, F-Droid. The topics its entry raises are chat and large language models.

That is our reading of the record. For AlternativeTo's own wording, see its page for Ollama App — 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

• Ollama App works with Ollama, and so does SumizAI: a local Ollama is one of its seven providers. You can keep the model on your own machine and still have the answers filed as Markdown notes rather than left in a chat window.
• Ollama App 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 .md file with a title, a place in base.md and a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI.
• AlternativeTo flags Ollama App as no longer developed. Whatever you put into it, you will eventually have to get back out — which is an argument for keeping notes in a format that outlives the application, and the reason SumizAI writes plain .md files into a folder you already own.
• AlternativeTo's description of Ollama App 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.
• Ollama App is open source (Apache-2.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Ollama App. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running.
• AlternativeTo's description of Ollama App 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.
