SumizAI and Brave Leo side by side: price, licence, platforms and what each one actually does. ## What Brave Leo is Brave Leo is an AI assistant built directly into the Brave browser, available on desktop (Windows, macOS, Linux) and on mobile (Android, iOS). Leo can read and summarize the page you're currently viewing, answer questions about an open PDF, or condense a long article — all without copy-pasting content into a separate chat window. Key features: Leo's free tier gives access to Llama 3.1, Qwen 3, Claude Haiku 3.5, and GLM, while Leo Premium unlocks stronger models — Claude Sonnet 4, DeepSeek R1, and Kimi K2.5. The Bring Your Own Model (BYOM) feature lets you connect a local or remote model of your own, or plug in an API key for a provider outside Brave's default lineup. Conversations require no account or login, are never stored on Brave's servers, and IP addresses are stripped before a request reaches the model provider. Who it's for: Leo appeals primarily to Brave browser users who want an AI assistant integrated directly into browsing, without switching between tabs or separate apps. Privacy-conscious users appreciate the lack of any account requirement and the no-conversation-storage policy. Use cases: In practice, Leo works well for quickly summarizing a long article while browsing, asking questions about the content of an open PDF without copying it elsewhere, and connecting your own model through BYOM if you already pay for access to a specific AI provider. Pricing and business model: The free tier runs with no time limits, and Leo Premium costs $14.99 a month or $149.99 a year, with a single subscription covering up to five devices. Brave's business model rests on subscriptions, not on selling user data to advertisers. Limitations and what to watch for: Leo's full functionality is available only inside the Brave browser, so using it means switching your default browser, which can be a barrier for people attached to Chrome or Safari. The free tier offers weaker models than the paid tier, so more demanding tasks require a subscription. AI notes straight from the page you're browsing: Leo offers no lasting notes system of its own, so an answer you want to keep as a ai notes entry has to be copied by hand into a separate notes app. For someone consulting Leo on dozens of pages a day, building an archive of ai notes from browsed content this way quickly becomes an extra, repetitive step. Privacy as part of Brave's product strategy: Brave has built its brand for years around blocking ads and trackers, so Leo's approach — no account, no conversation storage, stripping the IP address before a request reaches the model provider — is a natural extension of that same philosophy into AI, not an isolated marketing claim. What's worth checking before choosing: Before committing to Leo Premium, check whether the models available on the free tier are enough for your typical queries, and whether BYOM lets you connect the provider you already use. Bottom line: Brave Leo is a convenient, browser-integrated AI assistant with a strong privacy stance, but no lasting notes system. Anyone who wants ai notes from such sessions to land automatically in a searchable archive instead of requiring manual copying should consider a tool built around that workflow. Comparison with SumizAI: Brave Leo and SumizAI differ in context and purpose. Leo is an assistant woven into browsing, answering questions about the current tab's content. SumizAI is a standalone notebook where the conversation with an AI model is the main entry point, and answers worth keeping land automatically as Markdown files in the user's vault, on your own API key to one of seven providers — including a local Ollama, similar in spirit to Leo's BYOM feature. Anyone who wants a browser-integrated assistant for on-the-fly questions will pick Leo; anyone who wants these notes from AI conversations to build a lasting knowledge archive will find SumizAI the better-fitting tool. **Key facts** - Price: Freemium - License: Proprietary - Origin: United States - 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 - Brave Leo 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. - Brave Leo 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 Brave Leo 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. - Brave Leo also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work.
