Scoring version 2.3.1 · Test fixture anchor_pdfocr_v1
Honesty & reputation · 87/100 · 30%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Pricing transparency | 30 / 35 | Promoted as a 100% free online tool. Uploading the 644.4 KB 2-page scanned PDF without login finishes OCR recognition in 6.3s locally in the browser, popping up a results dialog that supports direct export in PDF and TXT formats. Unregistered devices share a daily limit across utilities; logging in provides 2 free exports per day. | Evidence A → |
| Interaction restraint | 25 / 30 | Clean workflow, though users must manually check the pages to recognize before clicking Recognize Text. The page footer and sidebar display third-party banner ads without obstructing the primary controls. | Evidence A → |
| Background & reputation | 17 / 20 | SaaS utility platform focusing on plagiarism detection, AI writing analysis, and lightweight online PDF tools. | Evidence A → |
| Engineering & privacy | 15 / 15 | OCR processing and PDF text stream reconstruction run entirely within the client-side browser WASM and memory, with zero document bytes transmitted to cloud servers, providing excellent privacy. | Evidence A → |
Capability · 59/100 · 70%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Task quality | 25 / 65 | Client-side WASM engine reconstructs a searchable PDF text layer (15 BT / 215 TJ operators), matching 4/4 section headings, 2/2 body phrases, and preserving the Page 2 verification token; however, dense table grid contents were omitted (0/12 confusable financial table cells, 0% table accuracy), resulting in 33.3% total text recall (25.0/65). | Evidence A → |
| Deliverable specifications | 20 / 20 | Exports a complete 2-page watermark-free searchable PDF (3,188.1 KB, with text layer) free of charge (20/20). | Evidence A → |
| Processing speed | 14 / 15 | Pure client-side browser WASM recognition with zero cloud data upload wait, end-to-end ready in 6.3s (14.0/15). | Evidence A → |
