I've been spending some nights & weekends building exactly this recently. I wanted something that managed my email & calendar, and proactively helped out (or nagged me) when it identified anything important.

It has a handful of core features:

- key obligations & insights are grok'd from emails and calendar events - these get turned into an ever-evolving always-up-to-date set of tasks; displayed on a web UX and sent to you in a personalized daily briefing - you can chat via telegram or email with the agent, and it can research/query your inbox or calendar/create or resolve tasks/email others/etc - if the AI identifies opportunities to be proactive (eg upcoming deadline or lack of RSVP on an event), it pings you with more context and you can give the green light for the agent to execute

Generally trying to identify finite list of busywork tasks that could be automated, and let users delegate the agent to execute them. Or, in the future (and with high enough confidence), let the agent just execute automatically.

Built the stack on Cloudflare (d1, Cloudflare Workers/Workfolows/queues, Vectorize), using gemini-3-flash as the model.

Would love any feedback: https://elani.ai.
