The Verdict
Eraser is built for engineering teams and solution architects, with a focus on diagrams-as-code and ai-diagrams. Phrase targets localization teams and enterprise companies and leads with translation-memory and machine-translation.

Eraser has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Phrase requires a paid subscription from day one.
