HOW IT WORKS

A design that keeps the data journey short

The tools use built-in browser capabilities to complete the task. Because input is not sent to a server, unnecessary copies and access paths are avoided.

Read the client-side architecture guide →
  1. 01
    Open input on your device

    Text exists only in the active browser tab.

  2. 02
    Run the local operation

    JavaScript, Regex, or Web Crypto produces the result.

  3. 03
    You control the result

    Review, copy, download, or close it with the tab.

WHY BYTEQUANT?

Auditable principles instead of flashy claims

↘

Local by default

Tasks that do not need a server stay on-device. Any future external service will be disclosed.

≋

Explainable methods

We disclose what scores and transformations use, including estimates and limitations.

□

One job, clear output

Tools focus on one problem without unnecessary dashboard complexity.

✓

Honest limitations

Automated output is never presented as expert opinion or legal compliance assurance.

Contact us
Is text entered into ByteQuant sent to a server?+

No. Core analysis and transformation run in your browser using JavaScript and Web APIs. Tool input is not sent to ByteQuant servers.

Do I need an account?+

No. The tools are free and require no account. Tool input is not saved to browser storage; theme and personal popular-tool counts may stay on this device without sensitive content.

Do results provide legal or security assurance?+

No. Masking and analysis are pre-checks. KVKK, GDPR, security, and legal decisions require qualified human review.

Why is the token count approximate?+

Each model uses a different tokenizer. ByteQuant estimates from characters and language so you can plan without transmitting the text.

Do the tools work on mobile?+

Yes. Core tools work in current mobile browsers. Some features, including Web Crypto operations, depend on browser support.

Does the site contain advertising?+

Reserved advertising areas are currently shown. If an ad service is activated, consent and privacy information will be updated before launch.
