MixedSentiment Notes
Positive: Highly effective for students, professionals, and non-native English speakers. Strong grammar/spelling detection. Negative: Major complaints about subscription billing practices and surprise annual charges. Poor customer service with no phone support. Recent Android app update removed keyboard feature causing user backlash. Tool can flag legitimate content as AI-generated, causing academic issues. Desktop app reported as buggy and slow.
Momentum Analysis
Revenue growth slowing from 40% (2024) to 12% (2023-2024). Strategic pivot with Coda acquisition (Dec 2024) and $1B non-dilutive financing (May 2025). Facing increased competition from ChatGPT and Microsoft Copilot. Superhuman acquisition (July 2025) and parent company rebrand (Oct 2025) signal major platform evolution from writing assistant to broader productivity suite. Company remains profitable with $700M+ ARR but showing signs of market maturation.
