Free Browser-Based Productivity Tools — AI Humanizer, Invoice Generator, Krutidev Converter & Calculators
i got my tools is a collection of free, browser-based tools built for people who need a quick, reliable result without installing software, creating an account, or uploading sensitive files to a remote server. Every tool on this site runs locally in your browser tab using your device's own processing power, which means your text, your invoice data, and your documents are never transmitted to or stored on an external server.
AI Text Humanizer
The AI Humanizer rewrites machine-generated text to read more naturally, adjusting sentence rhythm, vocabulary variety, and tone. It offers five distinct styles — Balanced, Ultra, Academic, Creative, and Casual — along with adjustable readability targets and a choice between US and UK English grammar conventions. A side-by-side diff view lets you compare the original and rewritten text line by line before exporting. Processing happens entirely in your browser using a local heuristic engine; no API key is required and no text leaves your device. The tool enforces a 5,000-word limit per run to keep processing fast and reliable.
Krutidev to Unicode Converter
This converter solves a specific, long-standing problem for Hindi, Marathi, and Nepali typists: legacy documents typed in the Krutidev typewriter font display as garbled, unreadable text in modern Unicode-based software. The converter maps Krutidev's non-standard character encoding to proper Unicode Devanagari script, recovering documents that would otherwise need to be retyped from scratch. It also includes local OCR heuristics for scanned Devanagari documents, and accepts PDF and DOCX uploads for text extraction.
Invoice Generator with Automatic Tax Calculation
The invoice tool builds professional, itemized invoices with automatic tax calculation, letting you save client and item details for reuse on future invoices without retyping them. Like the other tools on this site, invoice data is processed and stored only in your browser session — nothing is logged or transmitted to a server, which matters for anyone handling client financial details.
EMI, SIP, BMI, and Age Calculators
A set of focused calculators covers common financial and personal calculations: EMI (loan installment) calculations for comparing repayment scenarios, SIP (systematic investment plan) projections for estimating long-term investment growth, BMI for a quick health reference figure, and an age calculator that handles exact date-based age computation including leap years.
