Devin and Gemini are both AI tools that developers use, but they serve very different purposes. Gemini is Google's general-purpose AI assistant with strong coding capabilities, Workspace integration, and broad multimodal features. Devin is a specialized autonomous AI software engineer that works in its own environment to complete development tasks end-to-end. One is a broad AI assistant; the other is a focused engineering agent.
Devin
Devin is an autonomous AI software engineer from Cognition AI. It operates in an isolated sandbox with a shell, browser, and editor, reading GitHub issues, writing and testing code, and opening PRs without supervision. A free plan is available, with paid plans at $20/mo (Pro), $200/mo (Max) and $80/mo plus $40 per seat (Teams). The product line also includes Devin Desktop, the former Windsurf editor. Its narrow focus is software engineering, not general AI assistance.
Gemini
Gemini is Google's broad AI assistant with deep Workspace integration (Gmail, Docs, Sheets), a 1 million-token context window, real-time Google Search grounding, and multimodal capabilities. Recent updates include expanded agentic capabilities and Managed Agents through the Gemini API for production use cases. It can help with code in chat, and AI Pro and Ultra plans include Google Antigravity for agentic coding, but the Gemini app itself does not work inside a development environment the way Devin does. Paid access comes through Google AI plans: AI Plus at $4.99/mo, AI Pro at $19.99/mo and AI Ultra from $99.99/mo.
Key Differences
- Autonomy: Devin executes development tasks without supervision. Gemini provides coding assistance when asked.
- Specialization: Devin is exclusively a software engineering agent. Gemini handles a broad range of tasks across the Google ecosystem.
- Cost: Devin has a free plan and paid plans from $20/mo. Gemini has a free tier and Google AI plans from $4.99/mo.
- Environment: Devin has a real development sandbox. The Gemini app has no development environment, though Google Antigravity on AI Pro and Ultra adds agentic coding.
- Workspace: Gemini integrates into Gmail, Docs, and Sheets. Devin integrates with GitHub, Slack, Linear and Jira.
Pricing
Devin has a free plan, Pro at $20/mo, Max at $200/mo and Teams at $80/mo plus $40 per seat. Gemini has a free tier (Flash-Lite since October 9, 2026); Google AI Plus costs $4.99/mo, AI Pro $19.99/mo and AI Ultra from $99.99/mo.
Who Each Is For
Devin suits developers and engineering teams that want an autonomous AI agent that independently completes software engineering tasks.
Gemini suits Google Workspace users who need a capable general-purpose AI assistant with strong search grounding and productivity tool integration.
