Anyone built an email or calendar assistant that syncs and indexes data?

I’ve been exploring what it takes to build a simple email and calendar assistant that connects to Gmail and Google Calendar. The goal is to make it easy to search and reason over your own data in a useful way. The part I’m still trying to figure out is how much data actually needs to be synced and indexed. Some tools seem to just call APIs on demand, while others keep everything in a local or vector store for faster retrieval. If you’ve built something like this: - Did you bother syncing and indexing the data, or just query live APIs? - How painful is it to keep that data fresh without hitting rate limits? - Did you use something like Merge.dev or Composio, or just wire it all up yourself? I’m mostly trying to understand what the practical tradeoffs are before going too deep.
