Your questions, answered.

If you still have any questions, reach out. We (probably) won't bite!

    • How much can I index?

      The free and pro plans have a capacity limit of 4,000 and 20,000 pages, respectively, per account. Each page is approximately ~15 sentences worth of content, and we don't expect individual users to hit these limits. Business plans have no limits, and can offer usage-based pricing.

    • How does your search work?

      We built our own search engine which leverages advances in AI/ML to index content based on semantic meaning, not keywords. This approach makes us uniquely good at handling queries written in natural language, and powers many of our discovery-focused features.

    • I'm a developer, can I use this as an API?

      We offer a free API which lets you view the content and search over your personal indexes, as well as any public indexes. Business plans include full API access (i.e. read/write), which allows you to leverage our core engine inside your own products and services. Learn more.
