Frequently Asked Questions

Polymet vs Cognition AI: which should you choose?

If you need an autonomous software engineer for complex, multi-step enterprise workflows, Cognition AI's Devin is unmatched despite its opaque pricing and $10M productivity guarantee. For teams focused on rapid UI prototyping from text or images—especially those with a design system—Polymet offers a more accessible, code-focused alternative. Choose based on your primary bottleneck: full-stack engineering capacity (Cognition AI) vs. frontend design-to-code speed (Polymet).

Can Cognition AI generate frontend UI from an image?

No, Devin is an autonomous engineer focused on code tasks; it doesn't generate UI from images. Polymet is built for that.

Does Polymet execute multi-step engineering tasks like bug fixes?

No, Polymet generates frontend code from prompts/images but doesn't autonomously plan or execute complex engineering workflows.

Which tool integrates with Figma?

Polymet offers Figma import/export; Cognition AI does not integrate with Figma directly.

Is there a free plan for Cognition AI?

It is freemium, but the free tier may be very limited; enterprise pricing is opaque. Polymet has a free tier.

Which tool is better for legacy code modernization like COBOL?

Cognition AI explicitly supports COBOL modernization; Polymet is only for frontend code.

Does Polymet support version control?

Yes, it integrates with GitHub for version control, and can publish components to npm.

Which tool has a productivity guarantee?

Cognition AI offers a $10M AI Productivity Guarantee. Polymet does not offer such a guarantee.

Are there any legal risks with Polymet?

Recent news indicates Polymet is under regulatory investigation for fake betting videos; unrelated to its AI product, but concerning.
