Reviewing and correcting what the AI extracted
Hemma reads every invoice and quote with two independent AI providers. Most of the time they agree, the data is trusted, and you never have to think about it. Sometimes they disagree, or one of them is not confident. That is when a document lands in Needs review.
This is the article that walks you through resolving one.
01How you find a Needs-review document
There are three places.
- The amber strip at the top of the Files page tells you how many documents need your input. Tap Needs review to filter the list down to just those.
- Open any one of them and you land directly on the review screen — no extra click.
- The morning digest mentions it too, if you have notifications on.
02Three kinds of review
The screen looks slightly different depending on what Hemma was unsure about.
"Help me identify this document"
Shown when the AI was less than 80% confident about what the document is. Hemma did its best guess but wants you to confirm before extracting financial fields with the wrong assumptions.
What you see: a dropdown listing every type — Invoice, Quote, Permit, Plan, Photo, Inspiration, Tech doc, Other. Pick the right one and tap Confirm. Hemma re-runs the extraction with the correct type and the document moves on.
"These two readings disagree"
Shown when both AI providers read the document but came back with different values for at least one important field — the total amount, the VAT number, the invoice number, the date, the due date, the contractor.
What you see: side-by-side cards labelled Option A and Option B, each showing one provider's answer for each disagreeing field, with the confidence score. Tap the card with the correct value. Repeat for every field. Then Confirm.
You only see fields where the two providers disagreed. Everything they already agreed on is filled in silently — no work for you there.
"These line items disagree"
Shown for invoices and quotes when both providers got the totals right but produced different line-item lists (different number of lines, different descriptions). Pick which provider's list looks right and confirm. Hemma uses the asset-level numbers everyone agreed on and that provider's line items.
03What happens after you confirm
The document moves out of Needs review and into the regular flow. Amounts, dates, and the contractor are now trusted. The data starts driving budget signals and dashboards.
Behind the scenes, Hemma also writes an audit record: what each AI predicted, what you chose, which fields you corrected. That record lives with the document. If you ever wonder why the budget shifted by a few euros, you can trace it back.
You are correcting one document, not training the AI. Hemma does not retroactively change other documents based on what you picked here. If a contractor's name keeps coming through wrong on every invoice, that is a separate fix — see the AI extracted the wrong amount or contractor.
04You can override later too
The fact that a document is Trusted does not mean the values are locked. Open the document detail page any time. Every field — contractor, amount, date, type, tags — is editable. The original file never changes.
This is the glass-box principle: AI proposes, you decide, and you can change your mind whenever you want.
05Common questions
Why does Hemma not just pick the higher-confidence answer automatically? Because high confidence does not mean correct. The two-provider check exists precisely so the system catches disagreements rather than masking them. When you see Option A and Option B, you know the system noticed something worth checking.
What if neither option is right? Pick whichever is closer, confirm, then edit the field on the document detail page afterward. The audit log captures both your initial pick and the edit.
The "Help me identify" dropdown does not have the right type for my document. Pick Other. Hemma will store the file untouched and you can rename or tag it from the detail page.
How long does Hemma wait before flagging? Not at all — the review state is set during processing, which takes about thirty seconds. There is no extra delay added on top.
06What if it goes wrong
- Document seems to have been sitting in Needs review for a long time? See a document is stuck in "Needs review".
- You confirmed but the values still look wrong? See the AI extracted the wrong amount or contractor.
