~20 secondsWhat you get
Every analysis covers the four things that actually determine if an apartment is worth it.
Claude AI reviews up to 25 interior photos and scores five dimensions — Overall Condition, Kitchen, Bathrooms, Space & Light, and Finishes. Each rated 1–10. Kitchen counter space and usability weighted heavily.
Walk, transit, and bike scores plus real commute times to 6 Boston hubs on Tuesday at 9am. Back Bay, Downtown, South Station, Kendall Square, Fenway, and Logan Airport. School proximity included.
In-unit laundry, AC, parking, heat included, dishwasher, gym, outdoor space — detected automatically from listing and building data. Weighted for Boston's rental reality.
Zip-level ZORI rent benchmarks, adjusted for bedroom count and the unit's quality score. See the exact dollar difference between asking price and what the market says this unit is worth at its quality level.
Real verdicts

21 Radcliffe Rd · Allston
2bd · $2,950/mo
"Real hardwood, updated kitchen, Walk Score 93. Priced below what I'd expect for this quality in 02134. Tour this week."
447 Comm Ave · Brighton
1bd · $2,200/mo
"Functional but dated — 90s kitchen, carpet in bedroom. Good T access saves it. Fair price for what you're getting."
312 Newbury St · Back Bay
Studio · $3,100/mo
"You're paying for the zip code. Tiny studio, minimal light, almost no counter space. Better options exist at this price."
How scoring works
A weighted combination of photos, location, and amenities — weighted by how many interior photos are available.
