Data Sync
Data sync is the process of ensuring that data in two or more systems remains consistent, with changes made in one system reflected in others automatically or on a defined schedule.
Understanding Data Sync
Data sync is a foundational challenge in modern software. When a task is marked complete in your project manager, does that status reflect everywhere it's relevant? When a meeting is rescheduled in Google Calendar, does your Notion project page update? When a contact changes their email in your CRM, does your email tool reflect the change? Data sync is what makes these updates happen automatically.
Sync architectures range from simple to complex. One-way sync (source → destination) is straightforward: changes in the source propagate to the destination. Bidirectional sync is harder: changes can originate in either system, creating the possibility of conflicts when both change simultaneously. Conflict resolution strategies include last-write-wins, source-wins, and human-reviewed merges.
Sync frequency is another design decision: real-time sync (via webhooks) minimizes lag but creates more events to process; periodic sync (every 15 minutes, hourly, daily) batches changes but creates temporary inconsistency. The right cadence depends on how much staleness is acceptable.
For AI assistants, data sync quality directly affects response accuracy. An AI that reports on a task list that's 2 hours out of date might surface completed items as pending or miss newly created ones.
How GAIA Uses Data Sync
GAIA does not keep its own copy of your connected apps' data. When you ask about tasks, events or email, GAIA queries the source app (for example Linear, Google Calendar or Gmail) through its integration at that moment, so the answer reflects the data as of that query. Moving data between apps is the job of workflows: Gmail, Google Calendar, Notion, Linear, Slack, GitHub, Asana, Todoist, Google Docs and Google Sheets can start a workflow when an event happens, and other apps are checked on a schedule you set. What GAIA's memory stores is facts about you learned in conversation, not a mirror of your app data.

Webhook
A webhook is an HTTP callback mechanism where a system sends an automated HTTP request to a specified URL whenever a defined event occurs, enabling real-time notification and integration between services without polling.
API Integration
API integration is the process of connecting different software applications through their Application Programming Interfaces, enabling them to share data and functionality directly.
Event-Driven Automation
Event-driven automation (also called event-based automation) runs a workflow the moment something happens, such as a new email arriving, an issue being created or a row being added to a spreadsheet, instead of at a fixed time. Each automation pairs a trigger event with the actions to take, and the system where the event happened notifies the automation platform, usually through a webhook.
REST API
A REST (Representational State Transfer) API is a web service interface that uses standard HTTP methods (GET, POST, PUT, DELETE, PATCH) to access and manipulate resources identified by URLs, following a set of architectural conventions that make APIs predictable and interoperable.
