Update, June 2026: Windsurf is now Devin Desktop, sold by Cognition. Existing installs updated in place; plan names and prices on this page follow the Devin lineup (Devin Pro at $20/month, Devin Max at $200/month, Devin Teams from $80/month plus $40 per full seat). The Cascade agent was replaced by Devin Local.
Quick Verdict
Google AI Plus and Devin Pro are the budget entries in their respective categories. Google AI Plus at $4.99/month is the cheapest paid AI chatbot with Gemini model access and Google ecosystem integration. Devin Pro at $20/month is Devin Desktop’s baseline paid plan with SWE 1.7 and the Devin Local agent. They solve different problems at different price points — one for general AI, one for coding.
Where Google AI Plus Wins
Google AI Plus is the most affordable entry into paid AI assistance:
- $7.99/month — the cheapest way to access Gemini models beyond the free tier
- Google Workspace integration with AI features in Docs, Gmail, Sheets, and Drive
- Search grounding that connects AI responses to current web information via Google Search
- Gemini model access for chat, reasoning, and multimodal tasks (text, images, code)
- General-purpose AI assistant that handles research, writing, summarization, and basic coding questions
For non-developers and general users who want paid AI at the lowest possible cost, Google AI Plus delivers Gemini at under $8/month.
Where Devin Pro Wins
Devin Pro is built for developers who need an AI-powered coding environment:
- SWE 1.7 purpose-built model optimized specifically for software engineering tasks
- IDE-native code completions that predict your next edit based on project context
- Devin Local agent for multi-step coding tasks including debugging, refactoring, and feature implementation
- Terminal integration for running commands and viewing output without leaving the editor
- $20/month pricing — IDE-native coding AI with a purpose-built model
For developers who want IDE-native AI with a purpose-built coding model, Devin Pro now starts at the same $20/month rate as Cursor Pro, trading dollar-denominated usage for a fixed agent quota.
Pricing and Value
| Plan | Price | Category | Best Strength |
|---|---|---|---|
| Google AI Plus | $4.99/month | AI assistant | Cheapest Gemini access + Google integration |
| Devin Pro | $20/month | AI coding IDE | Purpose-built IDE-native coding AI |
Google AI Plus costs less per month than Devin Pro. Combined, the two subscriptions give you a general AI assistant and a dedicated coding IDE — two workflows a single ChatGPT Plus subscription ($20/month) doesn’t cover.
Who Should Choose Each
Choose Google AI Plus if you:
- Want the cheapest paid AI subscription available from a major provider
- Are not a developer and do not need IDE-native coding tools
- Use Google Workspace daily and want AI integrated into Docs, Gmail, and Sheets
- Need basic AI chat, search grounding, and multimodal capabilities
Choose Devin Pro if you:
- Are a developer who needs AI-powered code editing in an IDE
- Want an IDE-native coding tool with AI completions and agents
- Need the SWE 1.7 model optimized for software engineering tasks
- Prefer a purpose-built alternative to Cursor Pro ($20/month) or GitHub Copilot
The Budget AI Stack
The smartest play may be running both. You get Google AI Plus for chat, research, and Google integration plus Devin Pro for all your coding work, covering two distinct workflows that neither tool handles alone.
