Software That Generates Chords from User’s Melody? – Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum

Mario Nieto (developer of Harmony Bloom) is planning to release a new plug-in called “Chord Generator” on 9th December.

Here’s how he described it in another KVR thread “Building on my original concept of Random Chords Generator, I’m developing a VST/AU plugin that generates chord variations every time it receives a note.” No other details at this point, but he has been using it in the live streams he does on YouTube.

Perhaps keep an eye out for it, and see if it’s what you’re looking for?
