🦥 My Screenshots Folder Was a To-Do List That Never Reminded Me. So I Hired a Sloth

说明与用途

桌面上的截图变成了被遗忘的任务和暴露的敏感信息。本地工具 slothlens 在夜间处理它们，生成提醒、删除敏感内容并组织文件，生成每日摘要。

问题

Screenshots accumulate on a desktop as forgotten to‑do items and sensitive data, with no reminders or organization.

结果

After nightly processing, the user receives a digest of actionable tasks and a list of sensitive items to delete or secure, with all screenshots organized into folders and searchable by content.

工作流

• 1. Configure slothlens to run nightly during a user‑defined window (default 00:30‑07:00).
• 2. When the machine is idle, slothlens wakes, checks CPU and battery usage, and stops if conditions are not met.
• 3. It processes one screenshot at a time, sending the image to a local Gemma 3‑4B model via Ollama.
• 4. The model generates a caption and classifies the screenshot (e.g., "booking", "credentials", "error").
• 5. Text is redacted in three layers before being stored in SQLite.
• 6. Results are committed immediately; failed images are retried on the next nap.
• 7. In the morning, the user runs slothlens digest --html to view a Markdown/HTML report of to‑dos and sensitive items.
• 8. The user can search with slothlens find <query> or tidy up with slothlens tidy --apply and undo with slothlens undo.
• 9. The tool respects user activity, stopping if keyboard/mouse input occurs within 5 minutes or CPU >35%.
• 10. The tool runs with lowest priority (os.nice(19)) and does not drain battery when unplugged.

证据

A screenshot is an intention with no reminder attached.

来源

slothlens is a sloth that eats your screenshots while you sleep.

来源

After midnight, on AC power, when nobody has touched the keyboard for a while, it wakes up and reads your screenshots one at a time with Gemma 3 4B running locally through Ollama.

来源

No cloud, no account, no API key. Screenshots only ever go to the Ollama server on localhost, and extracted text passes through three layers of redaction before it is stored.

The sloth rules: Only works at night, Never drains your battery, Yields to humans, Yields to other work, Lowest priority on the machine, One bite at a time, Never loses its place.
