Introducing the Polymet MCP server!
Polymet now works with your favorite coding agent. Spin up projects, fire off generations, and move files, diffs, and assets both ways.

[Deniz Büyüktaş @dnzbuyuktas]

we needed a thinking animation; the little logo that pulses while the AI works.
so we asked @polymetai to design it.
one prompt: an interactive playground, 9 animation candidates, and the one we shipped to production.

[Polymet (YC S24) @polymetai]

What we shipped this week:
→ Polymet MCP: your coding agent can now build UI on Polymet for you
→ Shadows in visual edit: pick from your theme or build your own
→ Animated Polymet logo while the agent is working

Introducing file uploads
Attach 30+ file types to any prompt. Documents, spreadsheets, PDFs, and more. Just drag and drop, and the Agent builds with your context.

→ Queue messages - type your next prompt while the Agent is still building, and choose when it lands.
→ Auto design system - let the Agent pick a theme that fits your project, then refine from there.
→ Theme tab in Visual Edit - tweak colors, fonts, and radius right from your preview, no prompt needed.
→ Smarter color & font pickers - now pulling in your project's real colors and your Google Fonts.
→ Higher-quality image generation - cleaner, sharper results.

Same prompt, different models. Opus 4.8 vs Fable 5 vs Sonnet 5, all building the same landing page.
Honestly? They all nailed it. But which one's your favorite?
Check out the examples below 👇

Introducing Project Imports
Bring any existing project into Polymet. Import a @github repo or upload a .zip, and keep building right where you left off and sync back to Github.

[Polymet (YC S24) @polymetai]

Introducing upgraded image models
Create visuals for your projects with the best models available. FLUX.2 Pro by @bfl_ai for high-quality images and Recraft V4 by @recraftai for clean vectors, all powered by @fal, right where you build.

[Polymet (YC S24) @polymetai]

The latest Polymet changelog is live
→ The AI asks before it builds - open-ended request? Polymet now asks a few quick questions first, so your first version lands much closer.
→ New models - Claude Fable 5, Sonnet 5, and Opus 4.8 are here.
→ Slash commands - type / in chat to compact a long thread or clear it and start fresh.
→ Project rules & design context - set standing rules and a design file the AI follows on every generation, across every thread.
→ Typography in Visual Edit - click any text to change its font, size, and weight right on the canvas.
→ More image styles - quick drafts, high-quality renders, clean vector SVGs, and typography-focused graphics.
