In my earlier startups, I always felt buried under endless emails and an overflowing calendar. It wasn’t just the volume — it was the constant context switching, the little tasks that drained focus, and the feeling of never really being on top of things. That frustration is what led me to build Tisac. We’ve created AI agents that can take care of your Mail and Calendar tasks — things like scheduling meetings, checking availability, summarizing emails, sending/drafting replies in your tone and signature, and even sending them out for you. One key thing we wanted to solve was eliminating the need to open a separate webapp just to send an email, book an event, or handle trivial tasks. So, we built a web extension that lets you launch the agent from anywhere. Whether you’re casually browsing, reading, or deep in focused work — you can stay in context and still get the job done without switching tabs. We’d love your feedback to help us make this even better! As we like to say: “By giving people wonderful tools, we enable them to do wonderful things.” That’s been our belief at Tisac from day one — and it always will be. 🚀
