ToolsByValhalla is a collection of free online tools for everyday tasks: financial calculators, date and time calculators, health and percentage tools, secure generators and AI writing assistants. Every tool works instantly in your browser, with no account, no download and no paywall.
Who is behind ToolsByValhalla
The site is built and maintained by Valhalla IA, a small team based in Argentina that works on automation and artificial intelligence for businesses. We use tools like these every day in our own work, and we built ToolsByValhalla to offer clean, fast versions of them to anyone who needs a quick, reliable answer.
What we believe a good tool should be
- Accurate: every calculator uses standard, published formulas, and each tool page explains the method with a worked example you can check by hand.
- Private: calculators and generators run on your own device. The data you type is not sent to our servers or stored.
- Fast and simple: the tool is at the top of the page and the result appears instantly, without pop-ups or sign-up walls.
- Honest: we explain the limits of each tool. A BMI number is not a diagnosis and a loan estimate is not a bank offer.
How we create and check our content
Each tool page combines the tool itself with a plain-language explanation: how to use it, how the result is calculated, a worked example, tips and answers to common questions. Numbers in the examples are calculated and double-checked, and we link to reputable sources such as the World Health Organization, NIST and Wikipedia for further reading. When we find an error, or a reader reports one, we correct the page.
About our AI tools
The AI LinkedIn Summary Generator and the AI Instagram Caption Generator use a large language model to draft text. The details you enter are sent to the AI service only to produce your result and are not stored by this website. AI drafts are a starting point: always review and personalise them before publishing.
How the site is funded
ToolsByValhalla is free to use and is supported by advertising. Ads never change the results of a tool. See our Privacy Policy and Terms of Use for details.
