This MVP lets teams ask questions against approved company documents, but the engineering focus was different from a typical Q&A tool: every answer had to be grounded strictly in approved sources, with no fabricated additions, and every answer had to show exactly which document it came from.
Internal knowledge assistants are only useful if people can trust what they say. A tool that occasionally invents a plausible-sounding but unsupported answer creates more risk than the manual document search it was meant to replace.
This MVP was built around that constraint specifically: answers had to be traceable back to an approved source document, and the assistant needed a clear way to say "I don't know" rather than fill a gap with a fabricated response.
A general-purpose language model will often fill gaps with plausible-sounding information that isn't actually in the source documents. The system needed to be constrained so it could only answer from what was explicitly approved and available.
Telling users an answer is accurate isn't enough — they needed to be able to check it themselves. Every answer had to carry a visible link back to the exact document and passage it was drawn from.
Some questions people ask won't be answered anywhere in the approved documentation. The system needed to recognize that gap and say so clearly, rather than stretching an unrelated document into a false answer.
A Q&A assistant that answers strictly from approved sources and shows its work on every response.
The assistant only draws from documents explicitly approved for it to reference, giving teams confidence that answers reflect current, sanctioned information rather than stray or outdated material.
Each answer links directly to the document and passage it came from, letting users verify the answer themselves instead of taking it on faith.
When no approved document supports a clear answer, the assistant says so directly instead of generating a plausible-sounding but unsupported response, reducing the risk of teams acting on bad information.
Within a cited source document, the specific passage an answer was drawn from is highlighted, making verification quick rather than requiring a full re-read of the document.
Only documents marked as approved feed the assistant's answers, giving content owners control over what the assistant can and can't draw from.
Teams can review past questions and the sources cited for each answer, supporting spot checks on the assistant's grounding over time.
We defined what "trustworthy" needed to mean concretely for this assistant — grounding in approved sources and visible citations — rather than treating it as a vague quality goal.
We designed how the system would constrain answers to approved documents and how citations would be attached to each response at the passage level.
We built the question-answering pipeline with grounding and citation as built-in requirements from the start, not a layer added after the fact.
We built and tested the assistant's behavior for unsupported questions specifically, confirming it declined clearly rather than defaulting to a best guess.
We tested the assistant against a range of questions, including ones deliberately outside the approved documents, to confirm it never answered beyond what its sources actually supported.
We treated "never answer beyond the source" as a hard requirement, not a nice-to-have, and tested against it directly.
The assistant's responses are built to draw only from documents explicitly marked as approved, rather than any content it may have encountered elsewhere.
Every answer is built with a linked source and highlighted passage, not an optional footnote added afterward.
Saying "I don't know" was built as an explicit, tested outcome for unsupported questions, rather than left to chance in how the assistant might respond.
× Teams manually searched internal documents to find answers, often across multiple systems
× There was no way to verify whether an answer someone found was actually current or approved
× Inconsistent answers circulated depending on who searched and which document they happened to find
× No visibility into whether a given answer was actually supported by an approved source
✓ Teams can ask questions directly and get answers grounded in approved documentation
✓ Every answer links to its exact source passage for verification
✓ Questions with no supported answer are flagged clearly instead of guessed at
✓ Content owners control which documents the assistant can draw from
An internal assistant is only as useful as it is trustworthy, and trust has to be checkable, not just claimed.
By grounding every answer strictly in approved sources and attaching a citation to each one, this MVP gives teams a tool they can verify rather than one they simply have to believe.
"An assistant earns trust by showing its sources, not by sounding confident.
