SumizAI and BrainSoup side by side: price, licence, platforms and what each one actually does. ## What BrainSoup is BrainSoup is a modular AI platform empowering you to build autonomous assistants for any task, with a guarantee that your data stays private on your local device. The app comes from France, available on Windows only, describing itself as a tool with endless possibilities and inviting users to join its community. Key features: A modular architecture lets you assemble autonomous assistants from smaller functional blocks, matched to a specific task, instead of relying on one rigid chatbot. A guarantee of local, on-device data privacy sets BrainSoup apart from many cloud-based AI agent-building platforms, where data is processed on outside servers. A user community suggests an ecosystem of sharing configurations and assistant ideas among people using the platform. Who it's for: BrainSoup appeals to Windows users wanting to build their own, autonomous AI assistants matched to specific, repeatable tasks, while keeping full control over data privacy thanks to local processing. People experimenting with AI task automation but not wanting to send sensitive data to the cloud will find a matching offering here. Use cases: In practice, BrainSoup works well for building an assistant dedicated to a specific, repeatable process — automated document processing or monitoring specific information sources, say — where the modular architecture lets you assemble exactly the functional blocks needed, without unnecessary bloat. Pricing and business model: The app is paid, setting it apart from many free tools for building simpler chatbots — the price reflects a more advanced, modular architecture and an emphasis on local-processing privacy. Limitations and what to watch for: The app is Windows-only, with no Mac, Linux, or mobile version, limiting it to one desktop platform. A modular architecture also means a steeper learning curve than simple, ready-made chatbots — building your own assistant requires understanding how to combine individual functional blocks. AI notes from locally processed conversations: BrainSoup doesn't offer a pre-configured notebook-like archive — it's a modular platform for building assistants, so the mechanism for saving a ai notes entry from a conversation would depend on the specific configuration the user builds, not on a ready-made, built-in feature. Bottom line: BrainSoup is a modular, private platform for building autonomous AI assistants on Windows, with an emphasis on local data processing. Anyone who wants ai notes from AI conversations to land immediately in a ready-made, searchable archive without custom configuration should consider a tool built around that workflow. Privacy as a foundation, not an add-on: Many AI agent-building platforms process data in the cloud by default, treating local processing as an optional, premium add-on. BrainSoup flips that order — locality is the architecture's foundation from the start, which matters for teams working with data they don't want to send to outside servers at all, regardless of a cloud provider's stated privacy policy. Comparison with SumizAI: BrainSoup and SumizAI serve different purposes. BrainSoup lets you build your own modular AI assistants from scratch. SumizAI is a ready-made notebook built around a conversation with one of 7 AI providers, turning answers worth keeping into ai notes — Markdown files in a vault the user owns, with no module configuration needed. Anyone who wants to build their own modular AI assistants will pick BrainSoup; anyone who wants these notes from AI conversations to arise automatically with no configuration will find SumizAI the better-fitting tool. **Key facts** - Price: Paid - License: Proprietary - Origin: France, EU - Category: AI Chatbot, AI Writing ## 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 - BrainSoup 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. - BrainSoup 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 BrainSoup 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. - BrainSoup also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work. - AlternativeTo lists no mobile version of BrainSoup. SumizAI runs on macOS, Windows, iOS and Android. - Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
