PlugMyAI Daily · Monday, October 19, 2026
Four more apps you can plug into ChatGPT or Claude, plus two new things to try in Gemini.
Cotality's property data comes to Claude for its business customers
Cotality, a property data company used in mortgage, real estate and insurance, launched a connector that's listed and verified in Claude's directory. Authorized users can ask Claude about property details, market and rental trends, climate risk and home value estimates, depending on what their Cotality license covers. It's available to existing Cotality customers, not individual consumers.

Effivity brings ISO and safety compliance data into ChatGPT
Effivity, a tool for managing ISO, quality, health-and-safety and information-security compliance, says it's now officially available in ChatGPT after passing the ChatGPT team's app review. Existing customers open Plugins in ChatGPT's sidebar, search "Effivity", click Connect and sign in, then ask things like which corrective actions are overdue this month. Effivity says this follows its own recent listing in Claude's directory.

Hermoso lets you make and schedule ads from a ChatGPT chat
Hermoso, a marketing tool for ads and social posts, is now an app in ChatGPT's directory. After you add it and sign in, ChatGPT can pull competitors' ads from the Meta, Google and LinkedIn ad libraries, make image and video ads in your brand, and schedule posts to 11 channels, showing you each post before anything goes out. Adding the app is free, but it uses your Hermoso credits, and Hermoso says it shows the price before anything that spends them runs.

Agenda Hero puts your family and school calendars in ChatGPT and Claude
Agenda Hero's new connector lets ChatGPT or Claude check your Agenda Hero calendars, add events and make changes when you ask. In ChatGPT it's in the plugin directory: open it, select Install plugin and sign in. In Claude you add it for now as a custom connector with the URL https://agendahero.com/api/mcp; Agenda Hero says one-click setup for Claude is on the way.

Google's Universal Cart rolls out in the Gemini app and Search in the US
Universal Cart keeps products you save from different stores in one cart across Google Search and the Gemini app, alerts you to price drops and restocks, and shows relevant promo codes. You can check out with Google Pay at stores like Nike, Target and Walmart, or send the items to the store's own cart, and the store stays the seller. It's rolling out in the US.

Google Antigravity is now built into the Gemini app for Mac
You can now click Antigravity at the top of the Gemini macOS app to start a coding agent from your chat. It plans the work, builds and tests the code in the background, and lets you know when it's ready to review. It's available in English for personal Google Accounts and eligible work accounts (18+) in regions where Antigravity is supported.
