AdSpyfy is a Chrome side panel for performance marketers who live in the Meta Ad Library and Google Ads Transparency Center. It reads the public page you are already viewing, scores every ad by how long it has been live, and sorts the longest-running creative to the top so you can see what competitors keep paying for.
How it works: open the Ad Library or Google Ads Transparency Center, run a search, then open AdSpyfy. The panel captures all loaded ads, adds a days-running counter, lifecycle stage (test, proven, scaling or killed), and keyword/exclude filters that run over your captured set rather than sending new queries.
Use cases: media buyers validate an angle before spending; creative strategists pull hooks and formats into briefs; agencies build client boards and rerun saved searches weekly; ecommerce founders watch the brands they compete with.
Products: AdSpyfy is a free Chrome extension with a $99 Lifetime upgrade. Free includes 1,000 stored ads, keyword filtering, run-length sorting, single downloads and advertiser leaderboards. Lifetime adds unlimited storage, bulk ZIP/CSV/JSON export, the swipe file with notes/tags/boards, saved searches, local creative archive, advertiser comparison, video transcription, angle grid, landing-page snapshots, AI analysis with your own key and a local MCP server for Claude/Cursor.
Browser extension: the Chrome extension is the product. It adds a side panel, hotkey, auto-scroll, duplicate grouping, run analytics and hooks library.
Compatibility: any desktop OS that runs Chrome. Data stays in the browser; no account or upload is required.
Company: AdSpyfy is built by a small team focused on honest ad research. We read only public transparency pages, never proxy your AI key, and keep your data local.
