Why source tracking matters in AI tools

Every answer should include a pointer back to the source it drew from, not a vague summary, but a direct passage.

Why does source tracking matter?

Every answer should include a pointer back to the source it drew from,

not a vague summary, but a direct passage. Without that, the user

cannot verify, extend, or trust the result.

The shift

Most tools forget what you saved. XESO brings it back with sources.

Save a passage today. Next month, ask about it and XESO opens the line it used.

3 weeks ago

You saved a paragraph from a Substack post.

Title, link, and the passage you cared about, filed for later, tagged policy.

Today

You ask: “what did the Substack say about state caps?”

XESO answers from your saved passage and cites the line. Same source. New question.

Saved 3 weeks ago: Substack post, tagged policy

“…most proposals cap state contributions rather than abolish them; the version that passed sets the cap by median income, not a flat rate.” This is the paragraph you saved, reopened as the citation.

Library

One library. Notes, papers, meetings, all of it.

Transcripts sit beside PDFs and notes, with the same boundary and citations.

Import

Bring in supported files and notes.

Review imported items and their source details before relying on them.

Add

Add a source or a note.

Choose a supported file, link, or blank note. Add stays scoped to the library you can see; universal capture is not part of this release.

Design choices

Three choices we made on purpose

XESO is for people who treat a library like evidence: organized saves, scoped questions, and answers you can verify.

Your sources first

Answers start from what you saved, with passages you can open.

How to check an answer

Open the cited source passage and check that it supports the answer before you rely on or save it.

Hard boundaries

Scope chat to your whole library, one topic, or a single note.

Scope selector: chat

Library · Topic · Note. Chat context is bounded to the scope you pick; nothing outside the boundary is retrieved into the answer.

Serious-workflow posture

Review scope before sensitive work, and export notes when you need them.

No lock-in: plans & guarantees

Export your notes to JSON and Markdown, any time. Cancel in one click from Settings → Billing; no retention call, no dark pattern.

Pilot recruiting — delivery contingent

Bring company knowledge and work together.

We are recruiting a small number of companies to shape a guided design-partner pilot.

Early access is open

Start with one real source.

Add a source, ask a question, inspect the citation, and save the useful answer with your notes.
