Nova Act vs Cognition AI
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | Nova Act | Cognition AI |
|---|---|---|
| Pricing | Contact sales (no free tier) | Freemium (enterprise: contact sales with $10M guarantee) |
| Autonomy Level | API-based foundation model (generates text/code/images on prompt) | End-to-end autonomous agent (plans, codes, PRs, triages bugs) |
| Key Feature | Multi-model sizes on Amazon Bedrock, industry-leading price performance | FrontierCode eval, Auto-Triage, Devin Desktop, COBOL modernization |
| Integration Ecosystem | Amazon Bedrock (AWS-native) | GitHub, Slack, Windsurf, Jira, Linear, Datadog, Android Emulator, Windows VM |
| Ideal User | AWS developers building generative AI apps | Enterprise engineering teams, large codebases, legacy modernization |
| Latest News Impact | No recent news; limited public info due to paywall | New FrontierCode eval, $10M guarantee, Devin Desktop launch |
Cognition AI wins for teams needing an autonomous software engineer that can plan, code, and ship production-ready PRs with measurable guarantees, backed by concrete new features like FrontierCode and Devin Desktop. Nova Act is a capable foundation model offering for AWS-native developers, but its lack of recent innovation, public pricing, and autonomy means it's best for simpler generation tasks within the Amazon ecosystem.

Visit WebsiteWho should pick which
- Enterprise engineering team with large codebasePick: Cognition AI
Devin autonomously plans, codes, and ships PRs, integrates with GitHub, Jira, Slack, and offers a $10M productivity guarantee. Recent FrontierCode eval ensures merge-worthy code.
- AWS-native developer building generative AI appsPick: Nova Act
Nova Act offers multiple foundation models via Bedrock with cost-effective pricing, ideal for teams already on AWS needing text, code, or image generation.
- Team needing automated bug triage and fixesPick: Cognition AI
Devin's Auto-Triage autonomously monitors bugs, creates fix PRs, and integrates with Datadog and Jira—unique to Cognition.
- Developer needing inexpensive code generation onlyPick: Nova Act
For simple code snippets without full autonomy, Nova Act's pay-as-you-go via AWS may be cheaper than Devin's enterprise pricing.
- Enterprise with legacy COBOL systemsPick: Cognition AI
Devin explicitly supports COBOL modernization, a niche feature not offered by Nova Act.
