Last month I cancelled Notion, Todoist, Grammarly, a scheduling app, and a research tool.
I replaced all five with a single AI agent running on a $6/month server.
Here's exactly what I did, and how you can too.
The Apps I Killed
| App | Cost/mo | What It Did |
|---|---|---|
| Notion | $10 | Notes, docs, project tracking |
| Todoist | $5 | Task management |
| Grammarly | $12 | Writing assistance |
| Calendly | $10 | Scheduling |
| Perplexity | $20 | Research |
| Total | $57/mo |
The Replacement: One AI Agent
I set up an AI agent using OpenClaw (open-source) on a cheap VPS. Total cost: $6/month for the server + ~$10/month for the AI API.
$16/month instead of $57. That's $492/year saved.
But the real win isn't the money — it's having ONE interface for everything.
How Each App Got Replaced
Notion → Agent Memory
My agent has a MEMORY.md file. I tell it things, it remembers. I ask it things, it recalls.
No more organizing pages, databases, or templates. I just talk to it.
"Remember that the client meeting is Thursday and they want the API docs updated."
Done. It remembers. It'll even remind me.
Todoist → Agent Tasks
"Add to my tasks: finish the proposal by Wednesday."
"What's on my plate this week?"
The agent manages a simple task list. No app to open, no UI to navigate.
Grammarly → Built-in Writing
"Review this email for tone and clarity."
"Make this paragraph more concise."
AI agents are better writers than Grammarly ever was. They understand context, not just grammar rules.
Calendly → Smart Scheduling
"Find a 30-minute slot next week for a call with Sarah."
With calendar integration, the agent checks availability and suggests times. No separate scheduling link needed.
Perplexity → Agent Research
"Research the top 5 competitors in the AI writing space. Give me a comparison table."
The agent searches the web, synthesizes findings, and delivers a structured report. With citations.
The Setup (20 Minutes)
Step 1: Get a Server
Any VPS works. I use a $6/month instance. VPS comparison guide
Step 2: Install
curl -fsSL https://openclawguide.org/install.sh | bash
Step 3: Customize
Create a personality file that tells the agent your preferences, work style, and tools:
# SOUL.md
You are my personal productivity assistant.
I prefer concise, actionable responses.
Manage my tasks, notes, and schedule.
Step 4: Connect Your Messaging App
Telegram, Discord, Slack — pick your favorite. Now you can message your agent from anywhere.
What I Learned
- Fewer tools = less context switching. One interface beats five apps.
- AI understands intent. I don't need to learn a new UI for each task.
- It gets better over time. The more I use it, the more it knows my preferences.
- It's not perfect. Complex project management still needs dedicated tools. But for 80% of daily tasks, it's better.
The Honest Downsides
- Initial setup takes 20-30 minutes
- You need basic comfort with a terminal
- Complex Notion databases don't translate 1:1
- Calendar integration requires some config
Is It Worth It?
For me, absolutely. I save $41/month, have fewer apps to manage, and my workflow is faster.
If you're paying for 3+ productivity apps and you're comfortable with basic tech setup, try it.
