Productivity Kit - Text, QR Code & Calculator

Edit and transform text, calculate and convert values, and create QR codes, Pix payloads, and WhatsApp links without page access.

Edit and transform text, perform calculations, convert values, and generate results that are ready to copy directly from the Chrome extension popup, without granting the extension access to the pages you visit. Productivity Kit brings together useful tools for administrative work, content creation, customer support, and data organization. Simply type or paste the information, select a tool, and copy the result without opening a different website for every task. TEXT TOOLS Cleaning and normalization Remove punctuation, accents, line breaks, empty lines, repeated spaces, duplicate lines, and HTML markup from the text you enter. Letter case and transformation Convert text to uppercase, lowercase, and other available formats. Reverse text, apply prefixes and suffixes, and use Unicode text styles. Find, replace, and sort Replace terms using plain text or regular expressions. Sort lists, remove duplicates, and prepare data for documents or spreadsheets. Notepad Keep a note during the current session or enable persistent storage to retrieve it the next time you open the extension. CALCULATIONS AND CONVERSIONS Calculator with memory Perform arithmetic operations and percentage calculations directly from the popup. Amounts in words, slugs, and URLs Convert numerical values into written text, create slugs, and encode or decode URL content. Units and currencies Convert units of length, mass, temperature, area, volume, speed, and data storage. Check exchange rates between supported currencies when an internet connection is available. GENERATORS AND UTILITIES QR Code Create a QR Code from text or a web address and download the generated image. WhatsApp links Create wa.me links using a phone number and an optional message. Pix Copy and Paste Locally generate a Brazilian Pix Copy and Paste payment code and its corresponding QR Code. The extension does not verify whether the Pix key exists or confirm that a payment has been completed. Brazilian postal code lookup Look up the address associated with a Brazilian postal code, known as a CEP. Brazilian CPF, CNPJ, and São Paulo RG Mathematically validate CPF and CNPJ check digits and calculate the check digit for a São Paulo state RG identification number.

Select a tool from the side menu or use the search field. 3. Type or paste the information. 4. Run the desired operation. 5. Copy or download the result. PRIVACY The extension does not read the content of your tabs, browsing history, cookies, or visited pages. Most operations are performed directly on your device. The currency exchange tool sends only the selected currency codes to exchange-rate providers. The CEP lookup tool sends only the postal code entered by the user to the address provider. Preferences, persistent notes, calculator memory, recent items, and cached exchange rates may be stored locally by the extension. The clipboard is used only to write a result when the user clicks a copy button.
