You can zoom, drag, and rearrange them, or view the same board as a mind map, while typing @ creates bidirectional links that turn loose cards into a connected knowledge network. A tag-based database view lets the same cards double as a task list, book library, or web-clipper archive. Annotation is a core workflow. PDFs and videos can be dropped onto the canvas to highlight, comment, and generate linked knowledge cards; video annotations support timestamped notes from major platforms, so a quote in a lecture links straight back to the moment it came from. Sharing is one click — any canvas becomes an interactive webpage with optional password protection and no account needed for viewers. Unlike cloud-first tools, Flexnote stores files on your device by default and is fully usable offline. For multi-device work you connect your own storage via WebDAV, Amazon S3, OneDrive, or Baidu Netdisk, and credentials stay under your control. Flexnote AI runs semantic search and knowledge-base Q&A over your notes; chat uses your own model API key, and index points are bundled with Pro plans. A custom rendering engine keeps panning and editing smooth even at 10,000+ nodes. **Pricing & Plans:** Flexnote has a free plan with 3 whiteboards, 100 cards, core canvas features, and local storage. Pro and Lifetime plans unlock unlimited whiteboards, Flexnote AI smart-index points, and optional cloud sync; during promotional periods a Lifetime license has been offered at a discounted price. See the pricing page for current plans and point quotas. - **Infinite canvas with mind maps:** Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes. - **PDF and video annotation:** Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards. - **Knowledge-base AI:** Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key. - **Local-first with your own cloud:** Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours. - **Publish to the web:** Turn any canvas into an interactive webpage with a single link, with optional password protection and no account required for viewers. **Strengths:** Local-first storage means notes stay on your device and work offline; Combines infinite canvas, mind maps, and databases instead of splitting tools; PDF and video annotation with automatic reference cards is rare in note apps; Sync uses your own WebDAV, S3, or OneDrive accounts, so you keep control of data **Limitations:** The full web app is not finished; online access is view-only so far; Flexnote AI smart-index points are billed separately from AI chat usage; Advanced publishing and AI features sit behind the Pro or Lifetime tiers [Profile (Markdown)](https://openaitools.app/tool/flexnote.md) ## UBBLU UBBLU is built around a simple promise: search less, create more. Rather than treating notes as a filing cabinet you have to sort and remember, it treats them as a memory you can query. You capture ideas, inspirations, meeting notes, and key facts on the way in, and let the app handle recall on the way out. The structure is deliberately lightweight. Quick Notes capture fleeting thoughts, while Cards hold longer, more developed ideas and build into a richer knowledge base. Tags link and categorize notes and cards so related material stays connected, and folders, pins, and reminders keep the things you use most within reach. The headline feature is 'Ask', which spans notes, cards, folders, and tags: you pose a question and UBBLU brings back the relevant information instantly, so you never have to hunt for where you filed something. UBBLU also reaches beyond what you type. You can upload documents, ask questions about their contents, and save the insights back as notes. Grouping content under a tag lets UBBLU generate detailed answers and surface insights from the connected material. It is designed for thinkers who value creation over searching - the company's own framing. Sign-up is free with no credit card required. Note that UBBLU currently describes itself as desktop-only, with a mobile version announced as coming soon, so check device support before committing. **Pricing & Plans:** Free. UBBLU offers free sign-up with no credit card required for its core AI-driven note-taking and retrieval experience. - **Ask search across everything:** Ask a question in plain language and UBBLU pulls the answer from across your notes, cards, folders, and tags instead of making you scroll. - **Notes and structured cards:** Capture fleeting thoughts as quick notes and develop longer ideas as structured Cards that build into a knowledge base. - **Tags, folders, pins, and reminders:** Organize with tags and folders, pin the items you use most, and set reminders so deadlines and follow-ups do not slip. - **Connected discovery and insights:** UBBLU links related concepts and generates detailed answers and insights from the content grouped under a tag. - **Uploaded document interaction:** Upload documents, ask questions about them, and store the answers as notes for later retrieval. **Strengths:** Ask-based retrieval removes the need to remember where notes are filed; Lightweight structure of notes, cards, and tags is quick to adopt; Document upload with Q&A extends it beyond typed notes; Free to sign up with no credit card required **Limitations:** Currently desktop-only, with the mobile app still listed as coming soon; The public site is fairly minimal, so some details require signing up to see; Positioned as a newer product, so the ecosystem of integrations has room to grow; Note-taking habits are personal, and switching tools has a real learning curve [Profile (Markdown)](https://openaitools.app/tool/ubblu.md) ## Frequently Asked Questions ### How do Flexnote and UBBLU compare in monthly traffic?
