My laptop has no GPU, so I gave it the night shift

说明与用途

将“稍后”截图在没有 GPU 的笔记本电脑上使用 Gemma 3 4B 进行夜间处理，生成本地早晨摘要，无需将数据上传到云端。

问题

Screenshots taken for later never get processed, leaving 575 unreviewed files.

结果

The tool processes screenshots overnight on a CPU‑only laptop, producing a structured morning digest without sending data to the cloud.

工作流

• Point Later at the screenshots folder
• Run python -m later sleep --now --limit 5 to process a batch overnight
• Open the digest with python -m later which launches a local web page
• Review the organized items and use the tidy/undo features

证据

Later runs on your own laptop and opens as a web page on 127.0.0.1. Nothing is hosted, because the whole point is that your screenshots never leave your machine.

Gemma 3 4B averages about 33 seconds per screenshot. In a chat app that would be unusable. For a job that runs while I sleep it does not matter, so I designed around it.

Two locks on the secrets. A screenshot counts as private if the model says so or a deterministic check fires: OTP wording next to a code, a card number that passes the Luhn checksum, ID numbers, balances, password: lines, lab-report terms.
