Asistente RD was born in the Dominican Republic with a simple idea: everyday internet tools — calculators, converters, counters — should be fast, free and respectful of your privacy. No forced sign-ups, no artificial limits, and no uploading your data to someone else's server.
How our tools work
Every tool on this site runs inside your browser. When you use the word counter or a financial calculator, the computation happens on your device — nothing you type travels over the internet. That's faster for you and safer for your data.
How we choose and verify content
Each tool includes its formula, a worked example and answers to the most common questions. Formulas come from standard definitions (mathematical, financial, or official bodies) and are reviewed whenever regulations change or an error is reported. The last-review date is shown on every page.
The project
Asistente RD is also an AI-powered personal assistant that works on WhatsApp. This tools portal is the other half of the project: open utilities for everyone, wherever you are. The site is funded by non-intrusive advertising, which keeps every tool free.
