Tiztar

Done. Added as a priority task for tomorrow morning.

What it does

It organizes your day from the place where your day already happens.

Calendar and appointments

Syncs Google Calendar so the assistant can create and check events by chat.

Tasks

Creates and manages tasks with priority, status and due date.

Requests

Records directional commitments: what others owe you and what you owe others.

Proactive reminders

Writes to you on WhatsApp before a meeting, task or commitment.

Decisions

Keeps unresolved decisions with their options so they do not disappear in chat.

Work Center

Shows what needs your attention today, prioritized by time.

Availability

Respects your working hours and only offers valid slots when scheduling.

Conversational memory

Remembers context from your conversations to help with continuity.

Different by design

It is not a sales chatbot or a task list. It is a conversational assistant that acts with you on WhatsApp.

Connect WhatsApp and Google Calendar, define tone and availability, and let the assistant start organizing what needs your attention.

Founder trial

1 free month for founders.

Tell us how your day is organized today and we will review whether Tiztar fits your workflow.

We will use your data only to evaluate your founder trial request and contact you.
