AI Browsers Atlas and Comet Have Not Yet Displaced Chrome and Safari
Tests revealed that Atlas (OpenAI) and Comet (Perplexity) are operating inconsistently: they sometimes freeze, overload systems, and require user intervention. The issues are linked to website structure; users are calling for greater automation. OpenAI is updating the models.

AI browsers do not yet replace traditional solutions like Chrome or Safari. During tests it was noticed that Atlas from OpenAI and Comet from Perplexity behave unpredictably: sometimes they hang on simple queries, create excessive system load, and require user intervention.
Compatibility with websites
The effectiveness of such browsers largely depends on how web pages are built. Pages with a complex structure or a large number of visual elements are harder for AI to "parse", so some companies prepare simplified versions of sites specifically for generative AI tools — with a clear block structure, without animations and decorative elements.
A Mozilla survey showed that most users turn to generative AI for simple queries where they can personally verify the accuracy of the response. For critical tasks, such as buying tickets or planning trips, people still prefer classic search.
User scenarios and development
Users expect expanded automated capabilities: for the browser to perform routine actions itself — generate reports or update data on websites. Some already use such tools for everyday tasks: reading mail, processing video, or filling spreadsheets with the help of AI.
In addition, OpenAI is working on having models acknowledge mistakes and cases of instruction violations. ChatGPT has received the GPT-5.1 model, as well as an integrated shopping assistant, which is already available in Ukraine.
