Lass0

Anonymize text

Before a log goes in a support ticket or a document goes into a chatbot, the keys and names in it should come out. Switch on Lass0's cleaners and every capture or document is cleaned before it is copied. The same person gets the same stand-in throughout, so the text still makes sense.

A real example

The same handover memo, cleaned by the app on an Apple M1 Pro MacBook. Every combination is a real run. Highlights mark what changed.

Where things stand

In today's fast-paced landscape, it's important to note that the migration to the new invoicing engine is a testament to the team's dedication. We moved 1,240 Contoso accounts last month, and the remaining 310 move in the first week of December.

- Refunds over £500 still need sign-off from Person C
- The Stripe key in the staging vault is [API key] and must be rotated
- Monthly close runs on the second working day

How to do it

  1. Open Settings, then Cleaning, and switch on the cleaners you want.

  2. Capture a region or drop a document as usual.

  3. The cleaned text is copied. Switch to Original in the result if you need it.

Hiding secrets and personal details runs on rules and an on-device model, so the text you are trying to protect is never sent anywhere to be protected. Pro adds three cleaners that rewrite: one makes the text about any company, one makes it sound less machine written, and one rewords at least one word in ten.

Questions

What counts as a secret?

API keys and tokens from the common providers, private keys, passwords in config lines, database connection strings, IP addresses and long random strings that look like keys. Each becomes a labelled blank, such as [API key].

Will it miss things?

It can. Names in unusual formats are the hardest. Read the cleaned text before you share it; the timeline keeps both versions so you can compare.

Does the text leave my computer?

No. Lass0 reads the region with the text recognition built into your operating system and structures it with a small model that runs on your device. The only network calls are the one-off model download, licence checks for Pro, error codes and feedback you choose to send. The privacy page lists every one.

Is it free?

The free plan covers 100 plain text copies a week, with smaller allowances for rich text, Markdown and Visual layout. Pro is $6 a month or $48 a year and removes the limits, and adds copying from the timeline, Collect sessions and the three cleaners that rewrite text.
