ScreenMind vs Sublime Security

The capabilities don't overlap at all. ScreenMind is a capture-and-recall tool: content-change pHash detection instead of a timer, Gemma 4 vision analysis (app detection, activity categorization, mood, scene description, spatial layout), hybrid MiniLM + FTS5 search over your screen history, conversational RAG chat, Ctrl+Shift+V voice memos transcribed by Gemma 4's audio encoder, and auto-detected Zoom/Teams/Meet transcription with summaries. It runs on any 4GB-VRAM GPU or CPU-only, integrates with Claude Desktop, Cursor, VS Code, Obsidian, Notion, and exposes an MCP server. Sublime Security is an email defense platform: the Autonomous Security Analyst triages user-reported phishing, the Autonomous Detection Engineer authors backtested detections in Sublime Script, and every verdict shows matched detections and signal analysis. It covers BEC, vendor email compromise, credential/callback/QR/ICS phishing, prompt injection, and email malware, plus a behavioral threat-hunting interface and automated quarantine/remediation. One protects your own endpoint memory locally; the other protects an organization's email perimeter.

Pricing models barely intersect. ScreenMind is free — MIT-licensed, no telemetry, no subscription, no vendor SLA, with AES encryption at rest and a dashboard PIN lock. Your only cost is the hardware (any GPU with 4GB VRAM or CPU-only). Sublime Security is contact-sales enterprise pricing; nothing public. That's the standard signal for a platform sold on seat/tenant counts with onboarding, so expect procurement cycles and a detection-engineering workflow, not a signup. Sublime's own numbers claim 80% faster user-report investigation and 70% fewer false positives versus a prior stack — the ROI case is analyst hours saved and legacy secure-email-gateway consolidation, not a per-seat sticker. For a solo macOS user, the comparison is moot: ScreenMind costs $0 and Sublime isn't sold to you. For an enterprise, ScreenMind isn't a security control at all.
