Ventrar - AI agent for your calendar, inbox, todos, and projects

Ventrar is one workspace where you talk to an AI agent to run your day. Connect your Gmail, Google Calendar, Drive, Slack, and Apple Calendar; the agent reads your inbox, schedules events, drafts emails, creates documents, manages todos, and runs four-view projects - all from one chat, grounded in your real accounts.

Who Is Ventrar For?

Founders, operators, freelancers, and small teams who are tired of toggling between Notion, Asana, a calendar app, Slack, and ChatGPT. Ventrar collapses those into one chat surface that can actually act on your real accounts, with explicit user confirmation for anything that touches another person.

Frequently Asked Questions

What is Ventrar?
An AI agent workspace. One chat, your real accounts. The agent reads your inbox, schedules your calendar, drafts your emails, manages your todos, and runs your projects.
Is there a free plan?
No. Solo and Team both have 7-day free trials; after that, $15/month for Solo or $25/user/month for Team (minimum 2 seats).
How is Ventrar different from Asana or Notion?
Asana has no agent. Notion has no agent that actually reaches into your email or calendar. Ventrar is a chat surface that does the work - drafting emails, sending Slack messages, creating Google Docs, scheduling calendar events - and shows you exactly what it will do before doing it.
What project views does Ventrar support?
List, Kanban, Gantt, and PERT - all synchronized. Drag a Kanban card and the Gantt updates.
Does Ventrar have a native app?
Yes - iOS, iPadOS, and macOS with feature parity on chat, calendar, todos, inbox, workspace context, decision engine, and project views. Billing is web-only.

How it works

One agent. Every surface you live in.

Ventrar isn't a chat bolted onto a calendar. It's a single conversational layer wired into Gmail, Apple & Google Calendar, Drive, Slack, your todos, projects, and the decision engine - and it walks the same surfaces you do.

An AI agent workspace, not another to-do app

Ventrar is one chat surface that actually does the work - reading your inbox, scheduling your week, drafting your emails, creating real Google Docs, posting Slack messages, ranking strategic decisions - and shows you exactly what it will do before doing it.

Agent chat as your front door

Talk to your workspace. Ventrar's agent runs gpt-5.5 with tool calling, grounded in your real accounts and uploaded documents via RAG. Every external action goes through a propose-then-confirm flow so nothing ships without your review.

Connected accounts: Gmail, Calendar, Drive, Slack, Apple, Outlook

Connect once. The agent reads your inbox, schedules your calendar, drafts your emails, posts Slack messages, creates Google Docs / Sheets / Slides, and pushes events to your device calendar via the iOS / macOS app's EventKit mirror.

Unified Inbox + Slack triage

A two-stage classifier - regex prefilter plus batched LLM scoring - flags the messages that actually need you. Reason chips show why each one bubbled up: mentions you by name, time-sensitive ask, has a calendar invite.

Calendar with todos, events, and project deadlines on one time axis

Week and day views show everything you owe - events, todos, project milestones - in one synchronized timeline. Daily todos sync to your calendar. Drag from chat or projects onto a day. The native apps mirror your iCloud / Outlook calendar in real time.

Workspace Context + RAG over your documents

Drop in PDFs, docs, spreadsheets, slide decks, or free-text notes. Ventrar parses them, embeds them via pgvector with HNSW indexing, and re-ranks retrievals by triage score so the agent's answers stay grounded and citable.

Decision Engine + four synchronized project views

Rank strategic initiatives with structured reasoning (market conditions, growth potential, resource fit, competitive advantage, risk, time-to-results). Then run the work across four synchronized project views: List, Kanban, Gantt, PERT.

Three flat tiers: Solo $15/month (7-day trial), Team $25/user/month (minimum 2 seats, 7-day workspace-scoped trial), Business $50/user/month (minimum 5 seats, coming soon). No free plan. No Enterprise tier. iOS, iPadOS, and macOS apps included.
