Build a web app that helps local businesses reply to Google, Yelp, and Facebook reviews fast. 1) Connect review sources via API or paste a review manually for smaller setups. 2) Unified inbox listing every review with rating, source, and wait time, sorted oldest first. 3) AI drafts a reply matching the review's tone: empathetic for complaints, warm for praise, professional for mixed reviews. 4) Brand voice settings: user describes their business and tone once, and every draft respects it. 5) Compliance guardrails: AI avoids admitting legal fault, making promises, or including patient or client details, and flags reviews that suggest legal risk for human handling. 6) One-click edit and post back to the source, or copy-paste mode for platforms without write access. 7) Templates for recurring situations (refund complaints, parking complaints, praise for staff) so teams answer in seconds. 8) Team workflow: draft, approve, post, with an audit trail of who replied. 9) Monthly report: response rate, average response time, and rating trend.
