An AI shopping agent that shortlists only the top 1% of products for you
Every category is reduced to a single verdict table of the highest-scoring products, so you compare a handful of strong options.
Lists show how many sources were reviewed and how many products were ranked, plus when the list was last re-ranked.
Ask natural-language questions about a product category and get a recommendation grounded in the agent's research.
Paste a product URL or an Instagram reel and have the agent evaluate what is actually being sold.

Smart, focused email with AI help — for individuals and teams
Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.
