Strict content filters can sometimes interrupt conversations unexpectedly, even in non-problematic contexts, which can break immersion and frustrate users seeking creative freedom.
Characters can fall into repetitive response patterns during extended conversations, occasionally recycling similar phrases or narrative structures across sessions.
Since the platform prioritizes personality and engagement over factual accuracy, it should not be relied upon for research, homework, or any task requiring truthful information.

The free tier provides limited daily queries across all models, which can be exhausted quickly by active users, requiring a paid subscription for meaningful regular usage.
Running a persistent sidebar extension can consume additional browser memory and occasionally impact page loading performance, particularly on resource-heavy websites.
The quality and speed of responses depend on the selected AI model's current performance and API availability, meaning occasional latency or degraded responses during high-demand periods.
