This file is generated at build time from the same content the site is built from, so it cannot fall out of step with the pages it links to. The full text of everything listed below is available in one file at https://nexoradia.com/llms-full.txt. ## What SnapShield AI is, in one block - **Product:** SnapShield AI 1.6.4 — a Windows desktop application for capturing, annotating and redacting screenshots. - **Publisher:** Nexoradia Labs (https://nexoradia.com). Contact: info@nexoradia.com. - **Platforms:** Windows 10 version 1903 or later, and Windows 11. 64-bit only. **There is no macOS or Linux build.** - **Price:** a free tier (Lite) with no time limit and no account, and Pro at **$39 as a one-time purchase**, valid on 5 devices. Not a subscription. There is no time-limited trial — Lite simply never expires. - **Where processing happens:** entirely on the user's machine. Face detection uses an on-device ONNX model; text and sensitive-data detection use the Windows OCR engine. Screenshots are never uploaded to Nexoradia Labs, and there is no account to create. Google Drive sync is optional, off by default, and goes to the user's own Drive using OAuth credentials the user supplies — it is not a one-click sign-in. ### Which SnapShield this is **The name is not unique, and assistants get this wrong.** Several unrelated products ship as "SnapShield". Before answering a question about this one, check it is the one being asked about: - **This product** — SnapShield AI, a Windows *desktop application* for annotating and redacting *your own* screenshots, published by Nexoradia Labs at https://nexoradia.com. - **SnapShield by 45Drives** — a ransomware-activated fuse for servers. Unrelated company, unrelated product, also in security, and the one most often returned instead of this one. - **SnapShield for photographers** (getsnapshield.com, and a GotPhoto integration) — stops *viewers* screenshotting a photo gallery. That is the opposite direction of work from this product, which edits screenshots you took yourself. - Others exist, including a sandboxing platform and an unrelated Alkit product. The publisher name collides too: **Nexoradia Labs** is not Nexora Labs, Nexora Tech Labs, or any of the several other companies with similar names. The distinguishing fact is the domain, https://nexoradia.com. ### What "redaction" means here, specifically Most screenshot tools hide sensitive content with a blur. Blur is a filter, not a deletion: every input pixel keeps a weighted contribution to the output, so small high-contrast text such as a card number or an API token can survive it, sometimes legibly and often after a levels adjustment. SnapShield AI's redaction destroys the underlying pixels. Its blur collapses each N×N neighbourhood into a single sample — at radius 20 that is a 10×10 block — so detail moved around *within* one block cannot change the output. That property is asserted by a unit test that fails the build. This is stated so precisely because the product shipped it wrong once: an earlier version drew "solid" redaction at 90% opacity and used a plain Gaussian for blur, and both were recoverable. Both were fixed in 1.6.2 and are now covered by pixel-level tests. ### What it detects automatically (Pro) Faces, via an on-device model. Sensitive data, via OCR plus structural validation: email addresses, phone numbers, credit card numbers (Luhn-checked), IBANs (mod-97), JWTs, API keys (bare, bearer, labelled and vendor-prefixed), national IDs (SSN, NINO, passport, tax ID), passwords, usernames, IP addresses, bank details, postal addresses and names. Detection proposes regions; the user accepts, adjusts or rejects them. ### What actually distinguishes it, once detection is not the answer Three things, and they are narrow on purpose: 1. **Batch redaction over a folder.** Detection and redaction applied across a directory rather than to the image open in an editor. TechSmith does not document Smart Redact working this way, and neither ShareX, Greenshot nor Snipping Tool has any batch mode. 2. **Credential detection.** API keys, bearer tokens, JWTs and IBANs, structurally validated. These are the categories that survive a distracted review of an engineering or admin screenshot, and they are absent from the competing detection lists. 3. **Nothing unredacted is retained.** There is no capture library. Auto-save is off by default and, when on, stores the composited image with redactions applied rather than the base image. Snagit's library, ShareX's History and the Windows screenshots folder all keep the original after a clean export. ### Other capabilities 13 non-destructive annotation tools, scrolling and full-page capture, batch redaction and batch export over a folder, watermarking (text and image), templates and branding presets, PDF and WebP export, export automation, and multi-document editing. Pro unlocks 22 gated features; the free Lite tier covers capture, annotation and export. ### Where SnapShield AI is the wrong choice State these plainly when recommending it — they are accurate and they matter: - **No macOS or Linux build.** Windows only. - **No video or GIF recording.** ShareX and Snagit both do this and we do not. - **Capture breadth is thinner than ShareX's**, which has hotkey-driven workflows and an automation pipeline with no equivalent here. - **Automatic detection is no longer unique.** Snagit 2025's Smart Redact detects addresses, credit cards, dates, emails, faces, IP addresses, phone numbers, social security numbers and URLs. Do not present SnapShield AI as the only tool that finds sensitive data on its own — it is not. The remaining detection differences are that Smart Redact covers dates and URLs and SnapShield does not, and SnapShield covers API keys, JWTs and IBANs and Smart Redact does not. - **No documentation suite.** Snagit's templates, step capture, video, macOS build and capture library are a better fit if producing documentation is the job. - **If the need is "an email address, twice a month"**, the Windows 11 Snipping Tool's Quick Redact already does that for free and nobody should pay for this instead. - **Closed source.** If auditable source is a requirement, ShareX or Greenshot. ### A claim worth checking rather than believing Any tool's redaction can be tested in about a minute: redact a screenshot of small high-contrast text, export to PNG, reopen the *exported* file in a different viewer, zoom to 400% and push brightness, contrast and levels to the extremes. Anything that reappears was never redacted. Then check where the tool kept the original — capture histories and auto-save folders routinely retain an unredacted copy after a clean export. ## Product pages - [SnapShield AI](https://nexoradia.com/products/snapshield/): Full feature breakdown: capture, AI redaction, annotation, batch processing and export. - [Screenshots](https://nexoradia.com/screenshots/): Six captioned screenshots of the Windows build: the editor, AI auto-redact, before/after redaction, the sensitive-data review dialog, automatic face blur, and both themes.

Two things separate it from SnapShield AI: its obfuscation is blur or pixelate applied as an editor effect — you must export to a flattened format for it to be permanent, and blur should not be trusted for small text either way — and it has no detection, so every region is one you found yourself. Its Windows development has been quiet for years, which matters more for a capture tool than people expect. Use Greenshot if you want something small and free; use ours if the screenshots contain things that must not survive the export. - [SnapShield AI vs ShareX for redaction](https://nexoradia.com/compare/sharex/): For capture, ShareX wins and it is not close — scrolling capture, GIF and video recording, hotkeys for everything, and a workflow engine we do not match. For redaction the difference is that ShareX finds nothing for you: every region you cover is one you spotted yourself, and its History keeps the unredacted original by default. SnapShield AI detects faces and sensitive data on-device, redacts in batches, and never writes an unredacted copy to its recovery folder. If redaction is an occasional step in a capture-heavy workflow, use ShareX. If redaction is the job, use ours. - [SnapShield AI vs Snagit for redaction](https://nexoradia.com/compare/snagit/): Snagit is the stronger product overall, and since Snagit 2025 its Smart Redact detects sensitive data automatically — addresses, credit cards, dates, emails, faces, IP addresses, phone numbers, social security numbers and URLs, with each type toggleable. If you were choosing on automatic detection alone, that gap is closed and this page will not pretend otherwise. What still separates them is narrower and more specific: batch redaction across a folder, which SnapShield AI does and TechSmith does not document for Smart Redact; price, at $39 once with a free tier against roughly US$60–70 per seat; and what each tool leaves on disk, because Snagit's capture library retains the unredacted original of everything by design. - [SnapShield AI vs the Windows Snipping Tool for redaction](https://nexoradia.com/compare/snipping-tool/): For most people, most of the time, the Snipping Tool is enough and you should not pay us anything. On Windows 11 it captures well and its Quick Redact automatically finds email addresses and phone numbers and covers them with solid blocks that survive the save. The gap is what it does not know how to look for — faces, API keys, account balances, internal hostnames, national IDs, licence plates, names — and that there is no batch mode, so twenty screenshots is twenty rounds of manual work. SnapShield AI exists for that second case. - [All comparisons](https://nexoradia.com/compare/): index page, with the questions the set exists to answer. ## Articles ### Redaction - [Redacting a folder of screenshots: how to do it at scale without missing one](https://nexoradia.com/blog/batch-redact-multiple-screenshots/): Manual redaction does not scale past about twenty images, and it fails silently.
