Turn scattered contacts into an organized, searchable network
Upload your contacts once and organize them into named groups based on where, when, or how you met each person.
Describe who you are looking for in plain language and let the app surface the right contact instead of scrolling through lists.
Schedule nudges to reach back out to a contact at a chosen time, so valuable relationships do not quietly go cold.
Store the context of each relationship — conversations, preferences, next steps — right next to the person's profile.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
