Rabbithole

Rabbithole is a web based AI chat tool pitched as a launchpad for curiosity. Users sign in with Google, ask open ended questions on history, science and culture, and keep a history of conversations they can revisit and continue later.

Rabbithole is a conversational interface built around a single idea: following a question wherever it leads. The homepage frames the product as "a launchpad for your curiosity" and opens with a stack of sample prompts that set the tone: what happened to the Library of Alexandria, how humans first landed on the moon, how the Macintosh changed computing, how World War II reshaped the modern world, what sparked the Renaissance, and what secrets sit on the Voyager Golden Record. These examples show the intended use, which is broad intellectual exploration across history, science and technology rather than narrow task automation. In practice the tool behaves like a question and answer companion with memory. After signing in, a user can ask their own questions, keep a history of conversations, and return to earlier discussions to pick them up again later. That persistence is the core of the product: instead of treating each query as a throwaway, Rabbithole stores the thread so a line of inquiry can be resumed days later without rebuilding context. The layout is deliberately minimal, with a prompt stack on the landing page and a sign in gate before the conversation area. Access is handled through Google sign in, which keeps account creation to a couple of clicks. Signing in is also the point at which the Terms of Service and Privacy Policy apply, so there is no guest mode described on the homepage. The interface is entirely web based, and nothing in the source material describes mobile apps, browser extensions or desktop clients. Rabbithole sits closest to general purpose AI chat assistants, but it narrows the pitch. Where those tools advertise writing, coding and business workflows, Rabbithole markets itself to curious readers, students, hobbyist researchers and anyone who enjoys chasing a tangent. The trade off is depth of feature set: the homepage promotes conversation history and a clean entry point, not collaboration tools, document handling or integrations. Buyers looking for a lightweight thinking partner for open ended questions will find the framing honest; teams needing structured outputs should look elsewhere.
