    Assessment

    AI features

    • Multi-model search Search can run on Claude, GPT, Gemini, Grok and other models.
    • Pro Search Complex questions are automatically broken down into sub-questions and answered through multiple search passes.
    • Deep Research A research report that would otherwise take hours is produced, according to the provider, in around five minutes, including chart export.
    • Source citations Source references appear as clickable links directly in the answer text.
    • Focus modes Dedicated search modes for Academic, Reddit, YouTube, Writing, Finance and Math narrow the research.
    • Spaces Persistent workspaces with your own files, custom instructions and team sharing.
    • Comet browser The in-house Comet browser brings an AI agent as a sidebar directly into everyday browsing.

    Suitable for

    • Competitive and market research with traceable source citations
    • Fact-checking, where statements are checked against multiple models and sources
    • Longer research reports on niche topics via the Deep Research feature
    • Persistent research projects with your own files and instructions via Spaces
    • Less suitable for Less suited to free-form copywriting or brainstorming; the source rates ChatGPT or Claude as stronger there

    Limitations and notes

    • Free tier limited The free tier is limited to five Pro Searches per day, and the Pro plan with unlimited Pro Searches and Deep Research costs around 20 euros per month.
    • Check sources critically Despite citations, individual sources can be poorly weighted; critical review remains necessary.
    • Less suited to creative work For free-form copywriting or brainstorming, ChatGPT and Claude are considered stronger.
    • Data protection Pro users can opt out of training, and a GDPR-compliant enterprise plan is available for companies.
    • Translation gaps The German interface and search work well, but some UI elements are only partially translated.

    Quick start

    1. Open perplexity.ai and register for free.
    2. Run a first search on a current topic from your own field of work, with Pro Search enabled.
    3. Create a Space for a recurring research topic and upload your own files for extra context.

    Tips

    • Choose the right focus mode: Academic for papers, News for current events, Math for calculations.
    • Use Deep Research for extensive reports on niche topics, results often run to fifteen to thirty pages.
    • Set up Spaces with custom instructions, such as a role description as an industry analyst, for more consistent results.
    • Install the Comet browser to bring research directly into everyday browsing.
    • For fact-checking, compare several answers from different models rather than trusting a single one.
