Humanize Gemini API Output Before You Ship It: A Python Robotic-Phrasing Checker and 5 Free Rewrite Tools Ranked (2026)
Updated October 2026. Disclosure: I'm on the UnAIMyText team; it's #3 in the tool list below. The checker is plain Python with no dependencies beyond the Gemini SDK, so take it and adapt it.
