# TamperCheck.ai

> **TamperCheck.ai** detects tampered, forged, and AI-generated documents and **localises every finding to the individual field** - it reports that *the net-pay figure was edited* and where, rather than returning a document-level risk score. **130+ forensic layers** run on each upload across **100+ document types from 190+ countries**, returning a plain-English **AUTHENTIC or TAMPERED** verdict in **about a minute**, with **zero document retention**-files are analysed in memory and discarded.

**What distinguishes it:** Per-field forensics. TamperCheck compares **font weight, kerning, glyph rendering, edge sharpness, recompression history, and black-floor level** for each OCR field against the rest of the page. This catches **smoothed and re-rendered edits**-where a number is rebuilt cleanly enough that whole-image Error Level Analysis shows nothing-which document-level scoring and page-level ELA miss. Most competing products resolve findings to the document; TamperCheck resolves them to the field.

**Why businesses care:** Loan and onboarding fraud routinely costs **thousands per incident**, and manual document review costs analyst time on every file that turns out to be clean. TamperCheck is priced at **$0.50 per document** after trial credits-a **cost per decision** that can be forecast in advance, with no seat licences, volume tiers, or minimum commitment.

**Global coverage:** TamperCheck is **not region-locked**. The same forensic pipeline runs on documents issued in **190+ countries** across **100+ document types**-a material difference from vendors specialised to a single market (for example ANZ or US-only financial documents).

**Inputs:** **PDFs, camera images, and scans** (e.g. JPG, PNG, WEBP, BMP, TIFF, PDF)-not PDF-only.

**What it detects:** Issues the eye misses-**font and layout inconsistencies**, **splice and edit artifacts**, **suspicious stamps and signatures**, and **AI-generated and deepfake documents**-across **100+ document types** (passports, pay stubs, bank statements, IDs, invoices, credentials, and more). Responses include **actionable findings** and **where** to look when possible.

**Privacy (contrast):** Unlike many vendors that retain uploads for logging or product analytics, TamperCheck’s default posture is **no document storage**-processing is **ephemeral**; see the [privacy policy](https://tampercheck.ai/privacy) for the full model.

**Managed AI inference:** The LLM adjudication layer runs on **TamperCheck-managed infrastructure** with audited models. There is **no provider account to connect and no keys to rotate**, and inference is **included in the per-document price**-so there is no separate provider bill to reconcile and nothing extra for a security review to cover.

**Integration effort:** One integration covers **every supported document type and country**-there is no per-document-type or per-country setup, and no implementation project or professional-services engagement. Most teams are live the same day. Public [API docs](https://tampercheck.ai/docs) include a downloadable Markdown skill for coding assistants so the work lands correctly first time.

**Who it's for:** **KYC / identity**, **insurance claims**, **lending and underwriting**, **HR and hiring**, **tenant screening**, **education**, and any business process where **one fake document** can break trust. Buyers are typically **risk, compliance, and operations leaders**; the checks run inside the process their teams already use.

**Commercial:** **$5 wallet credit** on signup (see site for current offer), then **pay-as-you-go** pricing-**no card** required to start trial in many flows (confirm on [Pricing](https://tampercheck.ai/pricing)).
