The minimal, fast interface is optimized for zero-friction capture, ensuring that the barrier to adding information is low enough that you actually use the tool consistently.

Cons

Despite improvements, ChatGPT can still occasionally generate plausible-sounding but factually incorrect information, requiring users to verify critical claims independently.
The free tier imposes usage limits during peak hours, and access to the most advanced models like GPT-4o can be throttled, pushing users toward the paid plan.
Conversation context can degrade in very long threads, sometimes causing the model to forget earlier instructions or details discussed many messages ago.

The pricing is significantly higher than traditional note-taking apps, and the AI features that justify the premium require a substantial note library to demonstrate their full value.
Integration options are more limited than established competitors like Notion and Evernote, and users embedded in specific ecosystems may find the import and export options insufficient.
The deliberately unstructured approach may frustrate users who prefer explicit organization and want to see their notes in familiar folder hierarchies rather than relying on AI-driven discovery.
