SumizAI and DeepSeek side by side: price, licence, platforms and what each one actually does. ## What DeepSeek is DeepSeek is a Chinese AI startup and the name of its flagship chat assistant, built around the open-weight R1 model family released on January 20, 2025. R1 drew enormous industry attention because it delivered results comparable to top reasoning models from OpenAI (o1) at a much lower training and inference cost, sparking a loud market-wide debate about the real cost of developing large language models. Key features: R1 is a reasoning model — before answering, it generates a visible chain of intermediate steps, which helps with math, coding, and logic tasks. The model weights are open source under the MIT licence, allowing free commercial and academic use and letting anyone build their own smaller, distilled versions from the full model. The DeepSeek-R1-0528 update from May 2025 improved benchmark results, reduced hallucinations, and added support for function calling and structured JSON output. Who it's for: DeepSeek appeals both to everyday users looking for a free, capable chat assistant and to developers and researchers who want to run or fine-tune an open reasoning model on their own infrastructure, without paying for a closed provider's API. Use cases: In practice, DeepSeek works well for solving complex math and coding problems step by step, as a free alternative to paid reasoning models for everyday work, and as a base for building custom, fine-tuned models for teams with access to GPU infrastructure. Pricing and business model: The DeepSeek chat app is free on a freemium basis, and the R1 model weights themselves are fully open and free to download and run locally — the only cost is the hardware or cloud infrastructure needed to host the model yourself. Limitations and what to watch for: As a product of a Chinese company, DeepSeek is subject to local content and moderation regulations, which can affect answers on political or historical topics — worth factoring in when choosing a tool for use cases requiring full neutrality. AI notes built by hand from reasoning answers: People using DeepSeek to solve complex problems often want to keep not just the final answer but the visible reasoning chain too, as ai notes documenting the model's train of thought — with no built-in archive, building such a collection of ai notes takes regular, manual export from the chat window. Community around the open model weights: Releasing R1's weights under the MIT licence inspired dozens of derivative projects and integrations, from local chat front-ends to notebook plugins supporting ai notes generated by a local run of the model with no queries sent to DeepSeek's cloud. The debate over data security in Chinese AI models: Institutional users often ask whether conversations run through DeepSeek's cloud version could be stored on servers subject to Chinese law — one reason some teams choose to run the open model weights locally instead of using the hosted chat version, keeping their ai notes entirely within their own infrastructure. Impact on competitors' API pricing: After R1's launch, several major closed-model providers cut their API prices or rushed out cheaper variants of their models, showing how strongly a single release can shift the entire pricing structure of the large-language-model market. Availability through API and third-party integrations: DeepSeek also offers an API compatible with a widely used industry format, making it easier to integrate the model with existing developer and notes tools without writing custom connecting code. Fine-tuning the model for specialized tasks: R1's open weights let research teams fine-tune the model further for specific domains — law, medicine, engineering — something closed models available only through an API without weight access don't offer. That freedom attracts teams who want full control over the model's final behaviour, not just prompt-level tuning. AI notes from DeepSeek reasoning sessions: DeepSeek offers no built-in archive of past conversations — every chat session, even one with a visible reasoning chain, ends inside the chat interface, and a worthwhile answer someone wants to keep as a ai notes entry has to be copied by hand into a separate notes app. Impact on the language model market: Releasing R1 under an open licence at a low training cost pushed many other providers to revisit their pricing and open-weight strategies, and the debate over DeepSeek's actual training cost became one of the loudest topics in the AI industry in 2025. Distilled versions of the model: Beyond the full R1, DeepSeek released smaller, distilled variants that can run on more modest hardware while retaining part of the original's reasoning ability — lowering the barrier to entry for anyone wanting to experiment with reasoning models locally. What's worth checking before choosing: Before using DeepSeek, check the current privacy policy on conversation storage, and whether you want the cloud version or to self-host the open model weights instead. Running the model on your own hardware: The full R1 model needs serious hardware — GPUs with a large amount of memory — but smaller, distilled variants can run locally on much more modest machines, making experimenting with an open reasoning model accessible to individual enthusiasts too, not just teams with an enterprise-grade cloud budget. Choosing between the full and a distilled variant is a trade-off between answer quality and hardware availability that everyone has to weigh against their own resources. Bottom line: DeepSeek is a free, capable chat assistant built on the open R1 reasoning model, which reshaped the global conversation about AI training costs. Anyone who wants worthwhile answers from such conversations to land automatically in a searchable archive of these notes should consider a tool built around that workflow. Comparison with SumizAI: DeepSeek and SumizAI play different roles in the AI ecosystem. DeepSeek is a model provider and chat app with no lasting notes archive. SumizAI is a notebook where answers worth keeping automatically become these notes — Markdown files in a vault you own — with the AI model connected through your own API key to one of seven providers (though not DeepSeek directly at the moment). Anyone who wants a free, capable reasoning model to talk to will pick DeepSeek; anyone who wants worthwhile answers from those conversations to build a lasting archive of these notes will find SumizAI the better-fitting tool. **Key facts** - Price: Freemium - License: Open Source - Origin: China - Category: AI Chatbot, Large Language Model (LLM) ## 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 - DeepSeek 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. - DeepSeek is open source (MIT), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for DeepSeek. 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. - DeepSeek 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 DeepSeek 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. - DeepSeek also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work. - DeepSeek 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.
