NestBoard is a cozy visual home for your information: notes, links, tasks, files, app data, workflows, and ideas gathered into boards you can scan fast.
NestBoard takes the best parts of task boards and document tools, then turns them into a faster visual workspace. Your projects, research, writing, and daily information stay easy to see, switch, and return to.
Good for moving work through columns, but often too narrow when you need richer context, references, and documents in the same place.
Good for notes and knowledge bases, but less visual when you want many streams of information visible at once.
Brings both together with visual columns, rich cards, markdown docs, spaces, and instant board switching.
A board is a visual space where you define columns and place information cards inside them. Each board can match a different kind of thinking: research, writing, planning, study, references, or anything else you want to keep visible.
It is not locked to one work style. One board can be a reading board with source material, another can be a project flow, and another can be a home for docs, links, and ideas you want to remember later.
A workspace is a group of boards loaded together for a bigger area of life or work. Instead of opening one screen at a time, you keep a set of related boards ready to switch between instantly.
That means a writing workspace can hold your outline board, research board, chapter board, and reference board in one place. A study workspace can keep every subject ready without mixing it into your personal boards.
A card is a flexible information unit. It can hold tasks, links, images, markdown docs, timers, sub-items, tags, colors, and structured reference data. That is why NestBoard feels richer than a simple task board.
With md-writer and md-reader, cards can open full markdown editing and reading flows in a visual, intuitive way, so documents live inside the same workspace as the rest of your thinking.
Build visual boards with the columns and cards your flow needs. NestBoard gives you flexible structure without forcing you into a single app pattern.
Start on your desktop, continue on your phone. Encrypted sync keeps all your boards up to date everywhere.
Everything lives locally first. Works perfectly without internet. Syncs quietly when you're back online.
Full JSON import/export. Share boards as reusable templates, back up your data, restore with one click.
Every board should feel different: choose colors, set a background image, and keep a visual style that matches your project. You can also pick from favorite themes to launch new boards faster while keeping your workspace consistent.
Background discovery is powered by Unsplash, so finding high-quality images is fast and seamless.
Drag cards with your mouse, copy and paste with context menus, click through boards, or switch to full keyboard control when you want speed. It feels closer to moving files around your computer than fighting a rigid app flow.
Cards can be any information that you need, from quick tasks to full markdown documents, links, references, and structured notes.
Full markdown with live preview. Write docs, notes, chapters, and specs inside any card.
Sub-items with checkboxes. Break any task into steps and track progress with a visual bar.
Color-coded labels + custom tags. Filter your entire board by any combination instantly.
Start a focus timer directly on any card. Know exactly how long each task really takes.
Set deadlines. Overdue cards are automatically highlighted so nothing slips through.
Multi-dimensional filtering means you can slice your board any way you want. Combine color, tag, date, and custom filters simultaneously — no search bar needed.
NestBoard adapts to your workflow — not the other way around.
Chapters, outlines, research notes, character sheets — all on one board with rich Markdown.
Build a simple task flow with the columns you need. Move cards with drag-and-drop or keyboard shortcuts.
Save your best Gemini, ChatGPT or Claude conversations. Never lose a great insight again.
Papers, citations, screenshots, notes, links — organized by project with tags and filters.
The Boards Gallery makes NestBoard reusable. Import and sync boards automatically to keep templates, subjects, and research updates available on your device.
Columns for papers, citations, experiments, and conclusions. Perfect for academic research.
Every step to ship your product — from idea to launch day. 60+ cards across 8 columns.
Chapters, characters, world-building, plot threads — a complete writing workspace.
Curated prompts organized by use-case. Copy, remix, share your best AI conversations.
The Gallery launches with our community. Be first to publish your workflow.
Clip a page, send Markdown from a script, or connect an automation tool. NestBoard safely queues it and adds it to the board and column you choose when you sync.
Save articles, documentation, AI conversations, forms, or structured Markdown from your own tools.
Incoming information waits in a protected delivery area instead of directly changing your encrypted boards.
Choose the destination once. Your next sync places the card in the selected board and column.
