Mixed Chinese/English (10 samples)
| Engine | Avg CAR | Typical Errors |
|---|---|---|
| CaptureOCR Fast | 99.1% | Rare |
| CaptureOCR Accurate | 99.7% | Nearly zero |
| Windows Snipping | 89.3% | Splits mixed lines, wrong char boundaries |
| PowerToys | 88.9% | Same issue |
Why: PP-OCRv6 uses unified vocabulary (Chinese + English + 46 Latin scripts in one model). Windows OCR switches engines per-script, causing boundary errors.
Vertical Text (5 samples)
| Engine | Result |
|---|---|
| CaptureOCR Fast | ✅ Reads correctly (top-to-bottom, right-to-left) |
| CaptureOCR Accurate | ✅ |
| Windows Snipping | ❌ Reads horizontally → gibberish |
| PowerToys | ❌ Same |
Small Print (8pt and below, 8 samples)
| Engine | Avg CAR | Min CAR |
|---|---|---|
| CaptureOCR Fast | 97.2% | 90.6% |
| CaptureOCR Accurate | 99.1% | 98.4% |
| Windows Snipping | 84.7% | 72.3% |
| PowerToys | 83.2% | 68.9% |
Why Accurate wins: Small model has more capacity for degraded text. Fast mode still beats Windows on small print.

| Engine | Result |
|---|---|
| CaptureOCR Fast | 4/5 correct (1 rare char → □) |
| CaptureOCR Accurate | 5/5 correct |

The $2.99 Question
Windows OCR is free. CaptureOCR is $2.99 once.
Is 5% better CAR worth $2.99?
For occasional English use: No. Use Windows.
For daily Chinese/mixed workflows: Yes. Time saved on corrections alone pays for it in day one.
For compliance/offline requirements: Yes. Only option with full local processing + structured export.
Our Recommendation
- Keep Windows Snipping Tool for quick English one-offs
- Add CaptureOCR for Chinese, mixed, vertical, batch, or structured needs
- Use both — they complement, not compete
