SumizAI vs Kanbito

What Kanbito is

What Kanbito is

Kanbito is a free, open-source desktop app combining a Kanban board with a notes section, built for people who want to organize tasks without creating an account, paying a subscription, or relying on a single vendor's cloud. The app comes from Argentina and runs on Windows, Mac, and Linux from the same codebase.

Key features

Dragging tasks between columns — typically To Do, Doing, and Done — lets you manage work visually, and each task can be broken into subtasks, tagged with a color, and described with Markdown. A dedicated notes section with a tree layout sits alongside the task board, so longer project documentation or personal notes live in the same place as the to-do list. All data is saved locally as plain JSON and Markdown files in the user's Documents folder — no database, no server, no background sync. A system tray mode on Windows and Linux keeps the app within reach without taking up taskbar space.

Who it's for

Kanbito appeals to people managing personal or small-project task lists who value Kanban's simplicity over the elaborate features of enterprise project managers. Anyone tired of apps requiring an account and a subscription for simple task management will find a direct alternative here without either barrier.

Use cases

In practice, Kanbito works well for planning a freelancer's week by moving cards between columns, for keeping project notes alongside the task list without switching between two separate apps, and for offline work, where no cloud dependency means no interruption in access to your own data.

Pricing and business model

Kanbito is fully free and open source under the MIT license — no paid tier, no task limit, no ads. Because data is kept locally rather than on a vendor's server, there's also no subscription model funding development — the project's upkeep depends on the community and its creator.

Limitations and what to watch for

Local data storage means no built-in sync between devices — anyone who wants their board available on several computers has to handle folder syncing themselves, e.g. through a cloud storage service, rather than through a feature of the app itself. No mobile version limits use to desktops and laptops.

AI notes alongside the task board

Kanbito has no built-in AI model integration, but the notes section's Markdown formatting makes pasting a fragment of a conversation with an assistant as an ai notes entry next to a related task on the board effortless. Such an ai notes entry gets saved as a plain local file, so it travels along with the rest of the project if someone sets up their own folder sync.

What's worth checking before choosing

Before downloading Kanbito, check the current update frequency on GitHub and test whether the column and notes-tree structure fits how a given person organizes their work — the app deliberately skips the elaborate customization found in larger tools.

Bottom line

Kanbito is a simple, local Kanban board with notes, free of charge and free of conditions — good for people who want to manage tasks without a cloud or an account. Anyone who wants ai notes from AI conversations to land automatically in a searchable archive, not just next to a single task, needs a tool built around that specific workflow.

Comparison with SumizAI

Kanbito and SumizAI operate in different categories despite a partial overlap of interest in notes. Kanbito is primarily a task board with notes as an add-on, saved locally with no AI integration. SumizAI is a notebook built around a conversation with an AI model — question, answer, then a Markdown file in a vault the user owns, accessible from a folder with a `base.md` file and a table of contents. Anyone who wants a simple offline Kanban board with notes will pick Kanbito; anyone who wants these notes from AI conversations to land automatically in an organized archive will find SumizAI the better-fitting tool.

That is our reading of the record. For AlternativeTo's own wording, see its page for Kanbito — the facts above were read on 2026-08-16.

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.

Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Side by side

Where they differ

• AlternativeTo's description of Kanbito does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them.
• Kanbito is open source (MIT), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Kanbito. 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.
• AlternativeTo's description of Kanbito 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.
• Kanbito also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work.
• AlternativeTo lists no mobile version of Kanbito. SumizAI runs on macOS, Windows, iOS and Android.
