ChatGPT Plus costs $20/month. Claude Pro costs $20/month. Gemini Advanced costs $20/month.
I built my own AI assistant for $5/month. It's better than all three for my daily work.
Here's the math and the method.
The Cost Breakdown
ChatGPT Plus: $20/month
- GPT-4 access
- No persistent memory
- No messaging app integration
- No automation
- Shared with millions of users
My Setup: ~$11-16/month
- VPS: $5-6/month (Vultr, DigitalOcean, etc.)
- Claude API: $5-10/month (pay per use, not flat rate)
- Total: $10-16/month
But here's the kicker: I get features ChatGPT doesn't have:
- ✅ Persistent memory across all conversations
- ✅ Connected to Telegram/Discord/Slack
- ✅ Custom personality that knows my work
- ✅ Scheduled tasks (morning briefings, reminders)
- ✅ Web search and research capabilities
- ✅ File access on my server
- ✅ 24/7 availability
- ✅ Complete privacy — my data stays on my server
The API Cost Myth
"But API costs will be huge!"
Let's do the math:
- Average conversation: ~2,000 tokens
- Claude Sonnet: $3/million input tokens, $15/million output tokens
- 50 conversations/day = ~$1-2/day = $30-60/month
Wait, that's MORE than ChatGPT!
Not so fast. That's 50 conversations per day — way more than most people use. Realistically:
- 10-15 conversations/day = $5-10/month
- Light usage (5/day) = $2-3/month
And you can use cheaper models for simple tasks:
- Claude Haiku: 10x cheaper than Sonnet
- Route simple questions to Haiku, complex ones to Sonnet
- Average cost drops to $3-5/month

When ChatGPT Plus Is Better
Let's be honest:
- Image generation — DALL-E is built in
- Zero setup — Works immediately
- Mobile app — Polished native experience
- Plugins/GPTs — Large ecosystem
If you just want to ask occasional questions with zero setup, ChatGPT Plus is fine.
But if you want a personal assistant that knows you, connects to your tools, and runs 24/7 — building your own is better and cheaper.
The Real Value
The cost savings ($4-9/month) are nice but not life-changing.
The real value is:
- An AI that knows your context — No more re-explaining everything
- Always available — Message from any device, any app
- Automated workflows — Morning briefings, task reminders, research reports
- Complete control — Your data, your rules, your customization
