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.

Clean your inbox. Discover magic.
Every cleanup action is proposed first. Review suggested groups, keep any group unchanged, and only then approve the delete, move or unsubscribe — the tool never touches your mailbox unasked.
Sign in with Google or Microsoft instead of handing over a mailbox password. Access can be revoked from your provider at any time.
Zero AI sorts your inbox into spam, promotions, newsletters and important, so bulk delete and keep decisions can be made in groups rather than message by message.
Unsubscribe from any sender with one click, permanently block unwanted newsletters, and keep a record of every unsubscribe action taken.
