Mendi Neurosight vs Vector Search Bench

Mendi Neurosight lets you record fNIRS brain activity in real time, tag events during a session, and sync your data securely to the Neurosight web app. All recordings are encrypted and securely stored, giving researchers full control over their data with the privacy and protection required for sensitive work. Once synced, your sessions can be reviewed, visualized, and exported for deeper analysis and reporting. This version delivers the core functionalities for mobile data collection, with more features already in development as we expand the full Neurosight platform.

Vector Search Bench is a high-signal, no-nonsense benchmark suite for vector similarity search on iPhone. Measure how fast and stable your device can score embeddings using the CPU (Accelerate/vDSP) versus the Apple Neural Engine (Core ML)—with real metrics you can trust. What you can benchmark Exact Top-K vector search (dot-product similarity) CPU path: Accelerate / vDSP optimized scoring NPU path: Core ML Dense inference tuned for Neural Engine scheduling Query-by-query execution with repeatable timing Intricate performance metrics Latency distribution: median, p95 Throughput: QPS Recall@K vs CPU reference (sanity check) Memory footprint and dataset sizing knobs Built for real-world AI systems
