Phia
Phia is a shopping app and browser extension that checks whether a price is fair and finds cheaper alternatives, including secondhand. It draws on a database of about 250 million resale listings across 40,000+ sites, tells you if an item is high, fair or typical, and surfaces identical or similar options for less. Co-founded by Sophia Kianni and Phoebe Gates, it raised a $35M Series A in 2026 at a $185M valuation.

Our take
Phia does one job well: tell you if you are overpaying and where to buy the same thing cheaper, with unusually deep resale coverage. The extension is frictionless and it is free for shoppers, with real traction in users and retail partners. It leans fashion-first and the savings depend on resale availability, but as a price-sanity check before you buy it is genuinely useful.
Best for
Online shoppers, especially fashion buyers, who want a quick check on whether a price is fair and a nudge toward cheaper new or secondhand options before buying.
Pros
- Flags whether a price is high, fair or typical at a glance
- About 250M secondhand listings across 40,000+ sites for alternatives
- Free browser extension and app; quick to use
- Strong early traction and a $35M Series A behind it
Cons
- Fashion-first; less useful for other categories
- Savings depend on resale and alternative availability
- Best results need the browser extension installed
How it compares
General assistants and ChatGPT's shopping features compare new prices broadly; Phia's edge is depth in resale and price-fairness scoring for fashion specifically, closer to a focused price-comparison agent than a do-everything shopping bot.

Algolia
Algolia is a hosted search and discovery platform used across ecommerce and content sites. Its core is fast, typo-tolerant, highly tunable search, extended with recommendations and merchandising tools. NeuralSearch, its AI capability, runs traditional keyword search and vector-based semantic search in parallel on every query, so results reflect intent even when the words don't match exactly. Pricing has self-service tiers (Free, Grow and Grow Plus) that start at $0 with usage-based billing - for example around $0.40 per 1,000 records, plus per-1,000-request search fees beyond the included volume - while Elevate, the enterprise tier built around NeuralSearch, custom SLAs and dedicated support, is custom-priced (an AWS Marketplace baseline around $50K a year). For a mid-market store with 500,000 monthly searches and 250,000 products, Algolia estimates roughly $7,000-$22,000 a year on Grow Plus.
