What is BPMKeyFinder?

BPMKeyFinder is a web-based tool that analyzes the tempo (BPM) and musical key of audio files directly in your browser. All processing occurs locally using the Essentia.js engine, so your tracks never leave your device, ensuring complete privacy for sensitive or unreleased music.

The analysis delivers practical BPM normalized to the typical DJ range (60–180), standard musical key notation, Camelot wheel compatibility codes, major/minor mode, and a confidence score to gauge detection reliability. You can batch-queue multiple files for back-to-back analysis and, with a Pro plan, export results to CSV for syncing with DJ software like rekordbox or Engine DJ.

The responsive interface works on laptops, tablets, and phones, making it convenient for quick checks in the studio, at the booth, or on the go. Sample results illustrate the clear output format, helping you plan harmonic transitions with confidence.

Editaimg: An AI Image Editor Built by a Dev Who Struggles with UI The Backstory As a full-stack developer, I’ve always been "vision-challenged." I’m not great at UI design, and while I have some Photoshop skills, I use them so infrequently that I have to re-learn the tools every time I open the app. I wanted a way to edit images that didn't feel like a struggle. The Problem with 2023 AI In 2023, I tried building an AI editor, but it didn't work. Image-to-image models would often generate an entirely different picture when you just wanted to fix one small detail. It was expensive and unusable for real work. ### The 2025 Solution: Editaimg Technology has finally caught up. I built Editaimg to make professional editing as simple as a chat: Natural Language Editing : Describe what you want to fix in plain English. Precision Control : Replace or remove objects without ruining the rest of the image. Essential Utilities : High-res upscaling, smart background removal, and watermark cleaning. Scenario-Focused : Optimized for Amazon product shots and quick marketing assets. Stop struggling with complex tools. Just tell the AI what to do.
