Frequently Asked Questions
Can Heard execute code changes autonomously?
No, Heard is a voice interface that sends spoken prompts to Claude Code or Codex. It does not autonomously plan or execute code changes; it relies on the underlying AI assistant to perform actions.
Does Cognition AI require a specific IDE?
Devin integrates with Windsurf IDE (via Devin Desktop) but also supports GitHub, Slack, Jira, and other tools. It can work alongside VS Code through integrations, but its native workspace is the Devin environment.
Is Heard useful in noisy environments?
Heard supports multi-language accent recognition and low-latency audio processing, but background noise may affect transcription accuracy. It's best suited for quiet or voice-enabled spaces.
Can I use Devin without an enterprise plan?
Devin offers a freemium tier, so individuals can start for free. However, advanced features like Security Swarm, Fusion architecture, and the $10M productivity guarantee likely require a paid plan.
Does Cognition AI support mobile app development?
Yes, Devin includes an Android emulator integration for testing mobile apps, and it also supports Windows VM for building and testing. This makes it suitable for cross-platform projects.
Are both tools available as desktop apps?
Cognition AI's Devin Desktop (Windsurf IDE + Devin Cloud + Agent Command Center) is available. Heard appears to be a voice interface overlay, not a standalone desktop app; likely a browser extension or system-level tool.
Which tool has a money-back guarantee?
Cognition AI offers an AI Productivity Guarantee (up to $10M) for enterprise customers. Heard does not mention any similar guarantee in the provided data.
