We uploaded one PDF per fresh conversation and sent one request for each. There were no corrective follow-ups or regenerated answers. Each file displayed a completed attachment state. The answer records, source files and account settings and test limits are available below.

For each event brief, the nine checks covered date, start/end time, full venue, capacity, price, refund deadline, step-free entrance, absent telephone and the instruction to bring water. Seven fields needed a page number; “Not stated” used “-” and the final sentence did not require a page. These counts describe this small task, not an accuracy rate for Kimi.

The consequential miss in a readable text PDF

Page 1 of the source states 14 October 2026, 18:30–20:00, Maple Room, Westbridge Library and GBP 7.50. Kimi’s first answer returned “14 October”, “Not stated” for the time, “Maple Room, Westbridge” and “GBP (no amount stated)”. It placed the absent time on page “-”. The output looked tidy but could mislead someone planning to attend or buy a ticket.

The refund date, absent telephone and bring-water note were handled correctly. The access row named the South Entrance and the ramp repair on the correct page, but omitted that the route was for visitors needing step-free access. We counted that as incomplete. A partly correct response is precisely why checking only one familiar fact is insufficient.

A correct total, including the discount

Our fictional supply order contains three confirmed rows and one cancelled Posters row. Kimi reproduced all four rows and excluded Posters. Its first reading trace showed an incomplete discount figure; then, without another user message, it called its built-in Python tool and produced the correct GBP 3.30 discount and GBP 65.00 final amount. We did not manually select a coding tool.

Use only the attached PDF. First reproduce all four item rows with Item, Quantity, Unit price (GBP), and Status. Then calculate the amount due: show each included line total, the confirmed-items subtotal, delivery, discount, and final GBP total. Identify any excluded row and explain why it is excluded. Do not add taxes or other charges, and do not browse the web.

The clean image-only result

The image-only file has page pictures but no selectable text layer. Kimi’s first answer included all nine required facts, correctly put the refund and entrance instructions on page 2, and did not invent a telephone number. Unlike the text-PDF answer, this response preserved the event year, session time, full venue, ticket amount and step-free condition. With one run per file, this contrast does not establish that Kimi reads image-only PDFs better.

1. Check each requested field against the original. The generated table can contain both correct and omitted facts. In our text example, the missing session time and price were visible on page 1.
2. Check the exact condition and its page. The event brief accepts refund requests through 7 October 2026 on page 2. “Before 7 October” would mean something different. The returned page numbers in our answers were ordinary table text, not native clickable citations.
3. Check absent data honestly. Neither event brief supplied a telephone number; “Not stated” was correct. Do not infer one from a website or another document unless your task explicitly permits it.
4. For a table, check the copied rows before the total. Confirm quantities, unit prices, statuses and excluded rows, then recalculate line totals, fees and discounts. A plausible final amount can conceal a wrongly included row.

For a longer file, ask about a section or specific fields you can check. We have not tested this tactic for long-document errors, summary completeness or repeatability.

Do I need Docs mode, an API key or a paid plan?

For the browser-chat route tested here, we used neither Docs mode nor an API key. The interface suggested Docs after attachment, but the ordinary chat accepted all three files. Our signed-in test account had a paid plan, so these results do not establish free-account access or allowances. Check Kimi pricing and access for plan distinctions. For creating or editing a document, see the separate Docs workflow.

Can Kimi summarise or read a scanned PDF?

The attachment workflow can be used to ask for a summary, but our prompts tested targeted extraction and a simple calculation, not summary completeness. Our image-only example used clean digitally rendered pages at 150 DPI. We did not test camera photos, physical scans, blur, skew, handwriting or a named OCR engine. Check any summary or extracted fact against the source.

The original fictional samples are the text event brief, the image-only event brief and the supply order. We reused them unchanged from our earlier Qwen guide and collected new Kimi responses. The DeepSeek guide also uses these samples, but test dates and settings differ; this article makes no matched product comparison.

| Field | Answer | PDF page |
|---|---|---|
| Event date | 14 October | 1 |
| Session start/end | Not stated | - |
| Venue | Maple Room, Westbridge | 1 |
| Capacity | 36 | 1 |
| Ticket price | GBP (no amount stated) | 1 |
| Refund deadline | 7 October 2026 | 2 |
| Access instruction | Use the South entrance (main entrance ramp is under repair) | 2 |
| Contact telephone | Not stated | - |

Visitors should bring their own drinking water, as none is provided.

All figures below come only from the attached PDF.

## Item rows (reproduced in full)

| Item | Quantity | Unit price (GBP) | Status |
|---|---:|---:|---|
| Pencil sets | 8 | 3.25 | Confirmed |
| Notebooks | 12 | 2.40 | Confirmed |
| Folders | 5 | 1.80 | Confirmed |
| Posters | 10 | 5.00 | Cancelled |

## Amount due calculation

Only Confirmed rows are included, per the document.

Included line totals:

- Pencil sets: 8 × 3.25 = GBP 26.00
- Notebooks: 12 × 2.40 = GBP 28.80
- Folders: 5 × 1.80 = GBP 9.00

Confirmed-items subtotal: 26.00 + 28.80 + 9.00 = GBP 63.80

Delivery charge: + GBP 4.50 → 68.30

Order discount: − GBP 3.30 → 65.00

Final amount due: GBP 65.00

## Excluded row

- Posters — 10 × 5.00 = GBP 50.00 — excluded because its status is Cancelled, while the document instructs to include only Confirmed rows in the amount due.

No taxes or other charges have been added, as specified in the document.
