KEY FEATURES: NOTE TAKER Capture meetings, lectures, phone calls, and ideas with one tap. COET records hours of audio, transcribes it with AssemblyAI's world-class speech-to-text, identifies each speaker, and generates clean AI summaries using Meta Llama 4 running on Groq. Search, rewrite, and tag your notes. Export to Email, Notion, OneNote, Evernote, or anywhere you work. Replaces Otter and Rev. MEDIA AI Generate and edit images just by describing what you want β portraits, illustrations, product shots, scenes. Powered by Google Gemini 2.5 Flash Image (also known as "Nano Banana").

Verdict
The clearest difference is in-app purchases: WhatMail at none against COET's 2. WhatMail also leads on update cadence (every 2 weeks vs every 4 months). COET's advantage is iOS requirement (15.1 vs 26.0). On price, ads and device support there is nothing between them.
