About AnyTools

What it is

AnyTools has two parts.

• The tools. More than a hundred everyday utilities, including JSON and SQL formatters, Base64 and JWT decoders, a regex tester, generators, converters, calculators, and PDF and image tools. They run in your browser, need no account, and come in English, Vietnamese, Spanish and Portuguese, each with an article on how to use it.
• The study app. Upload what you are learning from. AnyTools then grounds chat, quizzes, a spaced-repetition mastery path and a 90-day learning loop in those documents, citing the page each answer came from. It runs on the AI accounts you already have, and it is in English.

Why

Most tool sites are slow with ads, speak only English, and copy thin answers. We wanted fast tools in several languages that process your data locally, each next to a real explanation.

The study app grew from the same idea. It does not sell AI time. It puts the models you already pay for to work on your own material, and it shows where every answer came from.

Principles

• Privacy first. Tool inputs stay in your browser. The study app keeps only what you save, and calls AI only through the accounts you connect.
• Open source. All the code is on GitHub under the MIT licence. Audit it, fork it, host it yourself.
• No dark patterns. No popups, no exit-intent modals, no fake urgency, no email-gated content, and no ads.
• Performance. Each tool loads its own code only, so a page never carries what it does not use.
