Can AI Help Me Compare Products While Shopping Online?

Yes. Jarvis (getjarvis.eu) is a screen-aware desktop AI assistant for macOS 12+, Windows 10+, and Linux that reads the product page open in your browser and helps you decide. Open two listings — say two laptops on Amazon — press Cmd+/ (macOS) or Ctrl+/ (Windows) over each, and ask "which is better value?" Jarvis captures the specs, price, and reviews visible on screen and routes them to frontier models from Anthropic, OpenAI, or Google to build a side-by-side comparison: what each wins on, hidden trade-offs, and which fits the use you describe. It reads the page you are on, so it works on any store, not just big retailers. It can save the winner to a Notion shopping list or set a Google Calendar reminder for a sale. It never trains on your browsing. A free plan (40 requests/week) lets you start; the Pro plan is $16/month.

Comparison sites are full of affiliate bias and stale specs. Jarvis instead reads the live listings you are looking at. Capture product A, then product B, and ask it to weigh them for your priorities — "I care about battery life and a quiet keyboard, not gaming." a faster model builds a clean pros-and-cons table from the visible specs, price, and star ratings, and calls out where the cheaper option quietly cuts a corner. Because it reads the rendered screen, it handles regional stores, a manufacturer's own site, or a marketplace seller page equally well, with no integration required.

Half of a buying decision is the stuff below the fold. Ask Jarvis to read the visible reviews and summarize the recurring complaints, or to check the shipping, warranty, and return terms on screen. A frontier model is good at separating genuine signal from one-off rants. Once you decide, its connectors close the loop: save the chosen item and a one-line rationale to a Notion or Todoist list, drop the link into a Slack DM to a partner for a second opinion, or add a Google Calendar nudge for when a price drop you spotted is likely. Memory keeps your stated preferences across sessions, so next time it already knows your budget.
