PII 检测:285+ 实体类型

我们的基于正则表达式的检测引擎以模式为基础的精确度识别超过 50 种个人信息。相同输入,相同输出 - 每次都是如此。

检测工作原理

模式匹配

为每种实体类型使用精心设计的正则表达式模式,确保在所有文档中结果一致且可预测。

置信评分

每次检测都包括一个置信评分(0-1),基于模式强度和上下文,帮助您过滤结果。

上下文意识

周围文本的上下文提高了检测准确性,减少误报,同时捕捉边缘案例。

How we test

Human reviewers spot-check the output each week.

We track recall and precision on a labelled set.

Bad runs block the deploy.

Long jobs use a few credits each.

You can top up at any time.

Unused credits roll over each month.

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.

Common questions we hear

Can the tool read scanned PDFs? Yes, with OCR.

Does it work on long files? Yes, in small chunks.

Can I roll my own rule set? Yes, save it as a preset.

Does it run offline? The desktop build runs offline.

Do you keep my files? No, the cloud build wipes after each run.

Will it learn from my work? No, we never train on inputs.

A short tour of the workflow

Upload a file or paste a snippet of prose.

Pick the entities you want gone from the draft.

Choose a method: replace, mask, hash, encrypt, or redact.

Press run and watch the side panel show each hit.

Skim the result and tweak any rule that misfired.

Save the cleaned file or send it to a teammate.
