I was about to download this as a 14 day trial and came across a free full version at Plugin Boutique. I have read it is free until at least July.
Website description:
Sculpt sounds seamlessly while staying in your flow and mix in the moment with Neutron Elements, the modern, AI-powered channel strip. The updated Assistant lives in the new Assistant View and intelligently suggests processing for your audio that can be fine-tuned to your liking and lets you mix even faster. Now you can also dynamically match the tone of your track to a sample or stem using improved tone-matching technology from your own library of references or a collection of presets. Add some serious power to your plug-in collection at an affordable price and bring your mixing workflow into the 21st century with Neutron Elements.
Mix in the moment
Neutron’s beloved AI-powered audio Assistant is now modernized into the new Assistant View, your intelligent control center that produces fast, personalized results. Powered by machine learning, the assistant listens to your audio and suggests processing and takes you to an intelligent control center where you can use the Intent Controls to make big sonic improvements. Dial in punch, distortion, and width to taste before jumping into the Detail View to fine-tune. This is your Mix Assistant, but even faster and more flexible.
Magically match references
Match references in real-time. Like magic. Dynamically match the tone of your track to a sample or stem using the new Target Library with tone-matching technology. Communicate your intent to Neutron by loading stem references into your Target Library to enable the Assistant to match your drums, bass, guitar, vocal, or audio track to the sound you are going for. Borrow from our presets, or build your own with stems, sounds, and acapellas for every situation.
Improved UI look and feel
Neutron has a new look, designed to jumpstart your mixing process. With new panels featuring Intent Control, you can jump right in to make both corrective and creative changes. Toggle between the Assistant View and the Detail View to customize your workflow.
Improved performance
Neutron is compatible with Apple silicon native (M1, M1 Pro, M1 Max) chips for faster processing.

Important note: For existing elements users - the new Neutron 4 Elements does not include any modules. To access the newest Neutron 4 modules and the Detailed View, explore the full Neutron 4 version.
this is free very frequently. Neutron 4 is the full version and a paid upgrade. Elements is still good as a basic tool though and free is free.
