Butu 🧸: a friendly browser companion that gets lonely when you leave your work

说明与用途

Butu 是一个 Chrome/Firefox 扩展，使用本地嵌入模型检测分心，并提供一只泰迪熊伙伴，帮助用户重新专注于任务。

问题

Students and workers often get distracted by unrelated web pages while working on assignments, leading to lost focus and time.

结果

Butu provides a lightweight, offline‑capable focus companion that detects distraction via a local embedding model and uses hand‑drawn visuals and voice to gently nudge users back to their task, improving focus without requiring external APIs.

工作流

• 1. User opens the extension and enters the task description and desired focus duration.
• 2. The extension loads a 17.5 MB embedding model (Xenova/paraphrase-MiniLM-L3-v2) via Transformers.js.
• 3. The model compares the task with the current page’s title, description, and visible text to determine relevance.
• 4. If the page is deemed irrelevant, the teddy bear appears and gradually draws crayon doodles, plays a music box, and speaks reminders.
• 5. The longer the user stays away, the more the bear’s drawings become unsettling and the voice becomes more urgent.
• 6. When the user returns to the task page, the bear disappears, the music stops, and a chime confirms focus is restored.
• 7. The session is logged locally in a handwritten scrapbook showing task, duration, and places visited.

证据

A small embedding model runs inside the browser to work out whether the page you're reading belongs to that task.

It compares your task with the page title, description and a short excerpt of visible text.
