Built for Creators & Marketers
Get Micro Tools is a collection of high-performance, browser-based utilities designed to solve daily calculation, formatting, and preview challenges without paywalls or friction.
About the Maker
Hi, I'm Abhishek. I build web utilities and digital products under the AK_Builds imprint. I created Get Micro Tools to address a persistent frustration in digital marketing and creator workflows: everyday tools are frequently locked behind subscription paywalls, cluttered with intrusive popups, or buried in bloated enterprise software.
