Every answer Cheiron produces comes with citations you can audit. Click any cited claim and the underlying source opens in the right-hand panel, with the exact passage highlighted. This is the verification habit Cheiron is built around.
The reason this matters is simple. AI gets things wrong, even when it's grounded in sources you trust. Cheiron pulls from PubMed, FDA, EMA, ICH, MFDS, and curated peer-reviewed journals, but you're the one accountable for what goes into a regulatory document, a stakeholder memo, or a clinical decision. Deep Citations lets you confirm or push back at the level of the underlying paper, before that work leaves your desk.
How to verify a citation
1. Click any cited claim
Every Cheiron answer comes with a references panel on the right listing all the sources it drew from. To focus on a specific claim, you have two options:
Click a sentence in the answer to narrow the panel to just the sources backing that statement.
Click the source bubble after that sentence to jump directly into Deep Citations.
2. Read the source quality signals
The metadata on each source card depends on the source type. Cheiron shows the signals you'd actually use to judge that kind of source, including:
Peer-reviewed papers: journal name, Impact Factor, publication year, authors
Drug labels and approvals: company / sponsor, indication, route of administration, dosage form, approval date
Regulatory guidances: issuing agency, document type, date issued
Every source card also includes a direct link to the original source for sharing or deeper review.
3. Open a source to see the passage
Click any source card to open the document with the cited passage highlighted in context.
Once you're in a source, you can move between the passages Cheiron drew from in two ways:
Click any highlighted box in the document to jump to that passage.
Use the numbered buttons at the top of the viewer to step through the cited passages. Each number is one cited passage from that source.
Both the numbered buttons and the highlight boxes themselves are color-coded, so you can see at a glance how each passage relates to the answer as you scroll through the document:
Light yellow marks passages tied to the sentence you're currently verifying. A single source can contribute more than one passage to the same claim.
Grey marks passages that appeared elsewhere in the answer — useful when you want to see what else this source supported beyond the sentence you started from.
4. Confirm or challenge
This is the step that actually matters. Read the highlighted passage and ask:
Does the cited passage support the claim Cheiron made?
Is anything taken out of context?
Is this the strongest source available, or might a better one be hiding nearby?
If the passage supports the claim, you're good to use it. If it doesn't, see When a citation doesn't match the claim below.
5. Follow up with Document Chat (when needed)
For supported documents (mainly PDFs), you can open Document Chat directly from the source panel and interrogate just that document. Use this when:
You want to dig deeper into a long source (CSR, label, guidance)
You need to check whether a different passage in the same document contradicts the cited one
You're reusing evidence in a report and want to find related passages

When a citation doesn't match the claim
It's uncommon but it happens. When the cited passage doesn't fully support what Cheiron's answer says:
Don't ship the answer as-is. The verification habit exists for exactly this case.
Re-ask Cheiron more narrowly. Often the issue is that the question was broad enough to invite a stretched generalization.
Use Document Chat to interrogate the cited source directly. It's grounded only in that document, so the answer can't drift.
Use the feedback button (👎) on the answer. This helps us catch patterns and improve the model over time.
The verification habit
The most important thing about Deep Citations isn't the feature, it's the habit. Every answer worth acting on should be verified before it leaves your desk.
For low-stakes questions ("what's the mechanism of action of X?"), a quick spot-check is enough. For any answer headed into a regulatory document, an internal memo, a publication, or a stakeholder conversation, expand every claim that carries weight. The thirty seconds you spend verifying is what makes Cheiron a tool you can stake your name on.
