Scored by a Toolio reviewer after real useOur verdict
Highlight text anywhere and QuickContext's right-click menu can translate it, explain it or run whatever custom prompt you've set up, using an underlying language model. Being open source, it can also be modified by anyone comfortable editing the code. It's a free, lightweight add-on rather than a finished consumer product with ongoing support.
