Paperguide stands out as an already powerful research tool with a solid foundation and an intuitive user interface, making it a viable alternative to Consensus.app.

The platform shows great potential, but there is still room for growth to match the level of established competitors. Addressing OCR limitations and the inability to select specific AI models could significantly enhance its utility, especially for academic work where different models excel in various tasks. Even if this meant allowing users to bring their own API keys, this would enhance sustainability and functionality.

It would be beneficial for Paperguide to draw inspiration from other research tools like Consensus, Perplexity, and Julius AI as they continue to develop and evolve.

Overall, Paperguide is a strong contender in the research tool market, with the potential to become a fully-fledged competitor.
