Tulyro is a free collection of practical browser-only tools — calculators, text utilities, developer helpers, and small generators. Every tool runs entirely in the visitor's browser: nothing typed into a tool is sent to a server, stored, or tracked.
How Tulyro tools work
Each tool is a self-contained client-side application. Calculations use plain, reviewable JavaScript logic that executes on the visitor's device, which keeps results instant and means our code never receives the values entered into a tool. There are no accounts, no saved history, and no database.
How tools are built and checked
Tulyro is built tool by tool. Before a tool is released, its calculation logic is covered by automated tests, and the page is checked for correct results with valid, invalid, and edge-case inputs, mobile usability, accessibility, and search metadata. Methodology notes and formulas are documented on the tool pages and in our guides so results can be understood and verified.
What Tulyro offers
The site includes calculators (age, EMI, mortgage, BMI, CGPA), writing helpers (word counter, text to speech, fancy text), developer utilities (Base64), and fun tools (invoice and chat mockups). All 11 tools are free, with no signup and no watermark.
