Cogmi vs ShopGuru

Cogmi maps your brain's cognitive performance throughout the day by combining data from wearable devices with science-backed cognitive tests. It provides a live daily brain map that helps users understand their mental state and optimize their work accordingly.

What sets Cogmi apart is its integration of real-time wearable data with cognitive testing to deliver fatigue alerts before mental crashes and early detection of brain fog. It uses AI to suggest tasks that match your current cognitive sharpness, enabling smarter scheduling of work and breaks.

Users can track how lifestyle changes like supplements, workouts, or sleep affect their cognitive performance over time. Cogmi supports both individuals and teams aiming to improve productivity and mental well-being by aligning tasks with real-time brain function. The tool is free to join and does not require a credit card to start.

ShopGuru is a free shopping assistant delivered as a Chrome browser extension and a web-based research tool. The extension adds a chat button on Amazon product pages so you can ask questions about reviews, specs, and buyer feedback without reading hundreds of comments yourself. The web app lets you describe what you need in plain language, then searches Amazon, Best Buy, Walmart, Target, and other major retailers and ranks options with match scores, value ratings, and written reasoning.

Most review tools either summarize one listing or give generic advice from a general chatbot. ShopGuru limits answers to product-specific data it can verify, and says plainly when it does not know something rather than guessing. That constraint matters on Amazon, where a confident wrong answer about sizing, compatibility, or durability is worse than no answer at all. The web research side goes further by comparing across retailers instead of stopping at a single store's catalog.

It fits online shoppers who want faster due diligence before checkout, deal hunters comparing prices across big-box sites, and anyone tired of tab-hopping between retailer search pages. You do not need an account to try the web research flow, and the Chrome extension is free to install.
