ChinaAI: DeepSeek consumer PDF reading tests
Test date: 22 September 2026 UTC. Source PDFs created 21 September 2026.

Three first requests in separate conversations at https://chat.deepseek.com/.
Search off; DeepThink off. Account plan and serving-model version not displayed.
No API requests, regeneration or corrective follow-up. Same fictional source
PDFs reused from the earlier Qwen guide; settings/dates differ, not a matched
app comparison. Image-only pages are clean 150-DPI synthetic renders, not a
physical scan or degraded-page benchmark.

First answers are unchanged text supplied by the app's Copy control. The
separate evaluation was checked against the source PDFs and visible snapshots.
All three met the predeclared checks. No general accuracy or speed estimate.

Read test-freeze.json and product-plan.md for pre-request prompts/settings and
criteria, evaluation.json for the independent AI-assisted checks, and
collection-notes.md for tool delays and pre-submission file-picker recovery.
No account identifiers, private chat URLs or credentials are included.
