SecureThink v2.0 is a ground-up rewrite — a native, standalone macOS app built for privacy-first AI, no compromises. What's new since v1.0: Zero dependencies. v1.0 required Ollama and terminal setup. v2.0 is fully self-contained — the MLX runtime and model weights are bundled inside the DMG. Drag to Applications, open, done. Optimised for Apple Silicon. Native MLX Core and Metal Performance Shaders tap directly into Unified Memory. Programmatic memory capping and aggressive cache clearing keep things fast even on baseline 8GB MacBook Air/Pro models. On-device audio transcription. Drop in a recording and a local Whisper engine transcribes, indexes, and lets you query or summarise meetings — entirely offline. Agentic file creation. Ask SecureThink to draft a contract, build a slide deck, or compile a spreadsheet. It writes native .docx, .pptx, and .xlsx files directly to your Mac. Interactive in-chat charts. Structured data outputs are automatically parsed and rendered as interactive Bar, Line, and Pie charts inside the chat window. Local OCR. An embedded OCR engine lets you import and query scanned documents, images, and screenshots — no cloud, no uploads.
