A prompt-driven, Pinterest-style AI concepting board from Google Labs, powered by the Nano Banana image model — being retired on September 28, 2026.

Google Mixboard is an experimental AI concepting board from Google Labs. Think of it as a Pinterest-style workspace where, instead of pinning images that already exist, you describe what you want and the tool generates the visuals. You start from a text prompt or a pre-populated example board, and Mixboard fills a canvas with roughly fifteen image blocks to react to. From there you refine: mix in your own uploads (from device, Google Drive, or Google Photos), add AI-generated text blocks, and edit with natural language — "combine these two," "make it warmer" — plus one-click "regenerate" and "more like this" to explore variations fast.
The image generation and editing run on Nano Banana, Google's Gemini image model, which is what lets you make complex edits and merges by typing rather than by hand. The output is a downloadable board: you can export it as a PNG or as a presentation, and share it via a link. Mixboard launched as a U.S.-only public beta in September 2025 and expanded to more than 180 countries on October 30, 2025.
One critical caveat: Google is shutting Mixboard down on September 28, 2026. After that date the site goes offline, shared board links stop working, and all boards, generated images, uploads, and prompts are permanently deleted. If you use it, treat it as a scratchpad — export anything you want to keep, and do not build a durable workflow on top of it. Nano Banana image generation continues to live inside the Gemini app after the Mixboard canvas is retired.
For content work, keep Mixboard's role straight: it is an ideation and visual-exploration tool. It helps you decide what a look, palette, or concept should be. It does not caption or reframe video, hold a brand voice across a set of posts, fan one idea into a carousel, blog, and newsletter, or schedule and publish anywhere.
Mixboard is where you figure out what something should look like; Kompozy is where that look becomes finished, published content. The handoff is a reference image. Once a board lands on the palette, composition, or product concept you want, export that image and bring it into Kompozy as a brand reference — that single asset is enough to drive a whole production run, and because Kompozy stores generated media durably, none of it evaporates on a shutdown date.
Concretely: feed a Mixboard concept image into Kompozy's face-locked image formats and it renders [Persona Photos](/glossary/persona-shorts) and Persona Infographics that keep your influencer's face consistent while matching the direction you set — Kompozy uses Gemini face-lock for exactly this. Take the same look into a brand-exact [Carousel](/glossary/hyperframes) rendered through HyperFrames, or into quote cards, a blog article, and a newsletter, all governed by one [Persona Brief](/glossary/persona-brief) so the batch reads as one creator rather than a pile of one-off generations. Then [Autopilot](/glossary/autopilot) schedules and publishes the finished set across the eight social platforms plus blog and email behind a per-post review. Mixboard narrows a hundred visual ideas down to one direction; Kompozy turns that direction into a week of on-brand posts and ships them. (If you like Nano Banana's editing but want a tool that is not being sunset, [Google Pics](/ai-tools/google-pics) is the sibling image workspace Google is keeping.)

Yes. Google is retiring Mixboard on September 28, 2026. After that date the site goes offline, shared board links break, and all boards, generated images, uploads, and prompts are permanently deleted. Export anything you want to keep beforehand. Nano Banana image editing continues inside the Gemini app.
Mixboard was available at no cost as a Google Labs beta. Because it is a free, experimental product with a fixed shutdown date, it is best treated as a scratchpad for ideation rather than a foundation for a repeatable content workflow.
Export the concept image from Mixboard, then bring it into Kompozy as a brand reference. Kompozy renders face-locked Persona Photos, brand-exact carousels, quote cards, a blog, and a newsletter that match the look, holds them to one Persona Brief, stores them durably, and schedules and publishes across nine destinations.
