XESO is a personal research library for people who build their work on what they read, watch, and save.

Most of us have valuable information scattered everywhere. Standard note apps store your files but can’t actually answer your questions. General AI tools can answer questions, but they search the whole internet and guess when they don’t know something.

XESO sits right in the middle. It is a single, persistent home for your PDFs, videos, meeting transcripts, and notes, paired with an AI that gives you answers directly from your own evidence.

You ask a question. You get a clear answer with a clickable citation pointing to the exact passage it used.

You are always in control of the boundaries. Want to search just one specific meeting note? A broad topic? Your entire library? Or expand out to the open web for more context? You choose. Crucially, if the answer isn't in your selected scope, XESO simply tells you. It never fills the gap with a guess.

We aren't trying to build another cluttered team wiki or a temporary upload-and-chat tool. XESO is built to compound. You capture information over time, search across everything you have ever saved, and watch your library get more useful as it grows.

Why people use XESO:

Capture real work: Easily save articles, PDFs, audio, video, and meetings.

Verifiable truth: Every answer includes a citation back to your original source.

You set the boundaries: Search your personal library by default, or scan the open web when you need to.

Total privacy: Passkey sign-in and absolutely zero training on your data.

No lock-in: Frictionless export. Your library is yours, whenever you want to leave.
