A task tree on the left, the selected task’s agent in the middle, and a web page on the right. — Bello Browser, with generated example tasks, conversation, and a local documentation page.

Your work, in focus

A tree of tabs for each task.

An agent when you want one

Bello’s engine or a configured ACP agent.

A familiar foundation

WebKit, the engine behind Safari.

Built around what you’re doing

One task. Everything beside it.

Reading, planning, building, or just browsing: keep the pages and conversations that belong together in one place.

Tabs belong to tasks

Gather related pages into a tree under a task. Switch tasks to focus on its tabs, with its title, status, due date and notes close at hand.

Your choice of agent

Add an agent to a task when it helps. Use Bello’s own agent engine, or connect an agent in Settings through the Agent Client Protocol (ACP). Tasks work without an agent, too.

A WebKit browser

Browse in Bello’s own Mac window using the same web engine as Safari. Your page sits beside the task and its conversation, so your work stays in view.

Knowledge that carries forward

Keep decisions, lessons and longer notes in shared Knowledge. Read a note’s history, discuss changes, and review it when its evidence changes or its review date arrives. Bello and connected ACP agents share the same notes.

Inside the app

Your work, and what you learn.

Real app window with nested task tabs, a completed agent conversation, and local release documentation. — **Tasks, chat, and a page.** The task’s conversation stays beside its tabs.

Real Knowledge page with shared notes, a selected decision, provenance, history, and discussion. — **Shared Knowledge.** Read, discuss, and review what your agents keep.

Privacy by design

Your tabs stay yours.

Your tabs are never shown to agents. Agents have no tool or API that reads your tabs or their page contents. Browsing and the task’s conversation stay separate.

Stored on your Mac

Tasks, notes, tabs and conversations are kept locally. Your provider keys stay in the app’s local credential storage and never reach the web interface.

When you use an agent, the messages and tool context you give it go to your chosen provider or ACP agent. Websites you visit connect as they do in any browser.
