Build Your Own AI Productivity Assistant
Connect Gmail, Notion, and Calendar into one assistant that sees your entire workflow—not just individual apps.
Connect your favorite productivity apps with secure OAuth integrations
The Problem
Your tools don't talk to each other. Calendar doesn't know about urgent emails. Task manager doesn't see your schedule. Notes are disconnected from inbox.
You need an assistant that sees your entire workflow. This guide shows you how to build one.
Before & After
Product Manager, Series B Startup
Before: "8am to 8:45 just triaging email, checking calendar, finding Notion pages. Not working—preparing to work."
After: "'What's on my plate?' → 90 seconds → briefing ready. Doing actual work by 8:05."
Why Now
128K+ tokens: entire day in one "thought"
Production-grade accuracy, no hallucinated actions
Connects email → Notion project → calendar deadline
Previous AI assistants worked within ONE app. Now they connect across all of them.
Build Your Unified AI Productivity Assistant
This is the first in a two-part series. For step-by-step setup instructions, see Part 2 below.
From Fragmented to Unified
"What should I focus on this morning?" used to mean inbox triage in Gmail, hunting notes in Notion, and calendar juggling.Now it takes 90 seconds. One assistant sees your entire workflow—triaging email, updating Notion, booking meetings.
The problem: tasks hid in your inbox, decisions in notes, schedules in calendars.The solution: one assistant that sees the relationships between them.
What It Does
An executive assistant who never forgets. Not a manager who decides for you.
Cross-App Intelligence
Reads Gmail, Notion, and calendars together to answer questions with full context—no more manual switching between apps.
Finds Answers, Not Just Data
Knows where your work lives and retrieves or updates the latest state automatically—understanding context, not just keywords.
Automates Routine Work
Drafts replies, creates/updates Notion pages and tasks, schedules meetings—freeing you to focus on strategic work.
Learns Your Style
Remembers tone, priorities, and templates so outputs feel tailored and authentic to your voice—improving with every interaction.
Async Workflows
Real work unfolds over multiple steps: draft → review → follow‑ups → scheduling → updates.You give one instruction; the assistant handles the rest.
Long-Horizon Autonomy
Preserves context across LLM turns and resumes until done. Fewer "nudge the bot" moments.
How It Works Under the Hood
Three specialized layers working together. Connect apps once via OAuth; the assistant coordinates everything with full audit trails.
Three Layers Working in Harmony
Intelligence Layer: Understanding Your Request
Interprets natural language, breaks into actionable steps, finds relevant context.
- Claude Sonnet 4.5: Natural language understanding
- Vector Search: Relevant context from history
- 128K Token Memory: ~300 emails in one "thought"
Orchestration Layer: Planning the Work
Coordinates apps, decides order, handles dependencies.
- Cross-Service Planner: "Schedule meeting" = check calendars + send invites + update Notion
- Specialist Agents: Each connector has domain expertise
- Parallel Execution: 3x faster than sequential
Action Layer: Executing Safely
Executes safely with full audit trails.
- OAuth 2.0 Security: You control access scopes
- Safe Retries: Idempotent operations, no duplicates
- Complete Audit Log: Every action logged with timestamps
Layer 1 understands. Layer 2 plans. Layer 3 executes. Full transparency.
Example Flow: Morning Briefing Request
Here's how your assistant processes "What's on my plate today?" across all three layers in real-time:
Key Insight: Steps 3-11 happen in parallel—the Orchestration Layer queries Gmail, Calendar, and Notion simultaneously, then the Intelligence Layer synthesizes all results into one coherent response. This parallel execution is why you get comprehensive answers in seconds instead of minutes.
The assistant decides which connector to invoke, executes actions with proper permissions, and returns verifiable links (e.g., updated Notion page or calendar invite).
Real-World Examples
Morning Briefing
"What's on my plate today?" — Get a briefing in 90 seconds: urgent emails with context, schedule with prep notes, and top tasks from Notion.
Good morning! Here's your briefing for Tuesday, October 5: 📧 **3 Urgent Emails** (of 47 new) 1. Sarah Chen: "Q4 Budget Approval Needed" [View →] ⚡ Response needed by EOD - draft ready for your review 2. Michael: "Client Meeting Moved to 2pm" [View →] ✅ Already updated your calendar - no conflicts 3. Legal: "Contract requires signature" [View →] 📄 Opens automatically when you're ready 📅 **Today's Schedule** (6 meetings) • 9:00am: Team standup (15min) Context: Review Project Alpha milestone from Notion → • 10:30am: Client call with Acme Corp (60min) Prep: Pulled latest proposal from Drive → Talking points drafted in Notion → ✅ **Your Top 3 Tasks** (from Notion Personal Tasks DB) 1. [HIGH] Finalize Q4 budget (due today) - Related: Sarah's email ↑ 2. [MED] Review engineering proposals (due Fri) - Status: 3 of 5 reviewed 3. [LOW] Schedule team lunch - Suggested slots: Thu/Fri 12-1pm ⏰ **Time Analysis** • 4.5 hours in meetings (vs. your 6hr limit) • 2 hours blocked for focus work • Suggested: Move 1pm meeting to tomorrow?
Cross-service intelligence: Sarah's Q4 budget email auto-links to your top task. Acme Corp meeting prep pulls latest proposal from Drive. 47 emails filtered to 3 urgent. 90 seconds total.
Project Kickoff
"Create a Notion page for Project Alpha, summarize relevant emails, and schedule a kickoff next Wednesday."It drafts the page, pulls bullet points from recent threads, and books the meeting with agenda.
Meeting Coordination
"Find time with Alice and Bob." It checks availability, selects an optimal slot, sends invites, and updates the Notion tracker.
Email Follow‑Up
"Which emails from yesterday need a reply?" It flags important unanswered messages and drafts polite responses or creates follow‑up tasks in Notion.
Beyond Basic Tasks
Inbox Triage Rules
Prioritize VIP senders, move low‑value threads to Later, draft replies for Action‑labeled messages.
Project Templates
Spin up a Notion project page from a template; attach goals, tasks, and timeline; link key emails.
Focus Planning
Rank tasks by deadline and importance; propose a time‑boxed plan with calendar holds.
Personal Analytics
Answer questions like "How many tasks did I complete last month?" with links to data sources.
Knowledge Reuse
Apply your own templates and style guides across repeated workflows—updated with fresh context.
What This Assistant Can (And Can't) Do
What It Excels At
- ✓Cross-Service Intelligence: Connects dots between email threads, calendar events, and Notion docs that you'd miss manually
- ✓Routine Automation: Morning briefings, email triage, meeting coordination—repetitive workflows you do daily/weekly
- ✓Draft Generation: Email responses, project outlines, meeting agendas that follow your templates and style
- ✓Context Preservation: Remembers your preferences, priorities, and patterns across all interactions
Current Limitations
- △Requires Your Judgment: Drafts emails but doesn't auto-send (by default); proposes actions, you approve
- △Setup Investment Required: Initial 30-45 minutes to configure; 3-7 days to "learn" your patterns; ongoing refinement for best results
- △Not a Replacement for You: Can't attend meetings or make judgment calls; won't understand unspoken context or office politics
- △Best for Routine Decisions: Excels at structured workflows; less effective for strategic planning or creative work
Think of it as an executive assistant who never forgets—not a manager who makes decisions for you. It augments your work by handling routine coordination, so you can focus on strategic thinking and relationships.
Implementation Guide: Step-by-Step Setup
This is the second part of our series—your hands‑on guide covering quick start, connector configuration, knowledge setup, and how your assistant evolves over time.
Before You Begin
Having a legible setup helps. Spend a few minutes mapping your workflows:
Mapping your personal workflows
- Gmail: Labels you care about (Action, Waiting, VIP), filters, priority senders
- Notion: Where tasks live, canonical project pages, template structure
- Calendar: Working hours, preferred time blocks, meeting etiquette
This clarity makes connector setup faster and your assistant more effective.
Quick Start (10 Minutes)
- 1. Open the Opulent OS Marketplace and install Gmail + Notion connectors
- 2. Grant secure access; verify scopes and read‑only vs. write where appropriate
- 3. Click "Use Connector" to start a session; begin with a natural prompt (e.g., "Morning briefing")
- 4. Add Knowledge in Settings and attach a macro (e.g., !focus) so you can invoke it in any message
Opulent OS supports major services out of the box. Some providers may require an additional credentials file—follow the connector's inline instructions.

Knowledge Configuration: Example & Tips
Example Knowledge (personal productivity)
## Purpose
Guide the assistant to triage my inbox, maintain Notion project pages,
and coordinate meetings.
## Guidelines
- Email: Draft responses; never send without explicit approval.
Prioritize VIP senders and Action label.
- Notion: Create tasks in Personal Tasks DB; include priority and due date;
link related emails.
- Calendar: Avoid Fridays after 3pm; 25/50‑min meetings;
include agenda link in invites.
## Output format
- Morning briefing: bullets with deep links (calendar, Notion, Gmail)
- Meeting invites: include goals, doc links, and next stepsHow Your Assistant Gets Better Over Time
Unlike static tools, your assistant learns from every interaction. Here's what to expect:
Foundation
- • Learns your email patterns (who's important, typical response time)
- • Maps your Notion structure and preferred databases
- • Understands your calendar preferences and meeting habits
Refinement
- • Adapts tone to match your writing style in drafts
- • Identifies recurring workflows to automate proactively
- • Reduces clarifying questions, increases confidence in actions
Anticipation
- • Proactively suggests actions before you ask
- • Recognizes patterns (e.g., "Friday afternoon = low priority tasks")
- • Creates custom workflows based on your unique habits
Compounding Value
- • Each knowledge block you add multiplies effectiveness across workflows
- • Templates become more personalized and context-aware
- • Cross-service connections get smarter and more nuanced
Real Example: Compounding Efficiency
After 3 months, one user's assistant reduced their "What's on my plate?" briefing time from 90 seconds to 30 seconds—without losing any information. It learned exactly what they needed to see first, how to format it, and which details to surface vs. hide.
