SumizAI and Ellydee side by side: price, licence, platforms and what each one actually does. ## What Ellydee is Ellydee is a privacy-first AI assistant built on open-weights models with encrypted conversation storage, the ability to exclude military contractors from your infrastructure, and radical transparency including per-user electricity and water tracking with built-in eco-mode. This US-based tool puts ethics and privacy at the center of its value proposition, unlike most mainstream AI assistants built on closed models with unclear infrastructure provenance. A freemium model lets people try core features for free, while a paid subscription unlocks full functionality, likely including higher usage limits or additional open-weights models to choose from. Availability online and on Android and iPhone means Ellydee is accessible across all major platforms, without favoring one mobile ecosystem over the other. Radical transparency about per-user electricity and water consumption is an exceptionally rare trait in the AI industry, where the environmental footprint of large language models usually stays hidden from the end user — Ellydee makes that information part of its brand identity, targeting users who are environmentally conscious and ethically concerned about the AI technology supply chain. Someone working at a human-rights NGO, using Ellydee precisely for its ethical positioning and its exclusion of military contractors from the infrastructure, over time carries out many sensitive conversations about delicate professional topics with the assistant. Despite Ellydee's encrypted conversation storage, a user may still want to keep the key takeaways from those conversations in a format fully independent of any cloud platform, even an encrypted one. SumizAI complements Ellydee exactly at that point: key takeaways from conversations held with Ellydee can be saved as ai notes in a local Markdown file, stored solely on the user's own device, with no dependency whatsoever on an external provider's cloud. Someone who especially values privacy, and chose Ellydee for that very reason, ends up with ai notes forming an extension of that same philosophy of data protection, this time fully local. These tools complement each other: Ellydee provides an ethical, transparent, and private platform for AI conversations built on open-weights models, while SumizAI ensures the key takeaways from those conversations survive as ai notes stored locally, fully consistent with the privacy philosophy that led the user to choose Ellydee in the first place. It's worth noting that this combination — an ethical AI assistant plus a local, independent these notes — creates a coherent ecosystem for a user for whom control over their own data and the environmental footprint of the technology they use matters fundamentally. An activist or investigative journalist working on a story requiring the utmost caution around information security, using Ellydee precisely for its encryption and ethical infrastructure provenance, will especially appreciate the ability to store key findings as these notes solely on their own drive, with no cloud intermediary whatsoever. That combination — a private conversation with Ellydee plus a local these notes file that never leaves the user's device — offers a level of control over sensitive information that no cloud platform can match, regardless of its declared level of encryption and transparency. **Key facts** - Price: Freemium - License: Proprietary - Origin: United States - Category: Large Language Model (LLM), Text to Speech ## 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 - Ellydee 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. - Ellydee 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 Ellydee 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. - Ellydee advertises encryption. SumizAI answers the same worry a different way: on the desktop the notes never leave your disk, and the material a question sends to the model is capped at the table of contents plus at most five notes — and the app shows you which five it used. - Ellydee 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.
