Google Mixboard is a free AI mood-board tool from Google Labs, shutting down Sept 28, 2026. Kompozy is the alternative that ships concepts as published posts.
There are two reasons you might be searching for a Google Mixboard alternative, and they point at different answers. The first is that Google is shutting Mixboard down on September 28, 2026 — after that date the site goes offline and every board, image, and prompt is permanently deleted — so you simply need a replacement that will still exist next month. The second is that you tried Mixboard, liked it for brainstorming, and then hit its wall: it makes mood boards, and a mood board is not content you can post.
Be clear about what Mixboard was, because it was good at its narrow job. It is a Pinterest-style AI concepting board from Google Labs where you prompt an idea, get a canvas of Nano Banana-generated images, and remix them with natural-language edits. For exploring a palette, a look, or a product concept, that is fast and pleasant. If pure ideation is all you want, the honest same-lane replacements are things like Google Pics (the Nano Banana workspace Google is keeping) or Canva.
I run Kompozy, so I have a side, and I will name the boundary: Kompozy is not a mood-board tool. It is not the tool you reach for to brainstorm a hundred visual directions on an infinite canvas. What Kompozy is, is the thing that takes the one direction you settled on and turns it into finished, on-brand, published content — face-locked persona images, brand-exact carousels, quote cards, blogs, newsletters, avatar video — scheduled and pushed across platforms. If Mixboard left you with a great-looking board and no way to ship it, that gap is the whole reason this page exists.
Everything below is grounded in Mixboard's stated capabilities and its confirmed September 28, 2026 shutdown (verified 2026-09-02 against Google's Labs support pages) and Kompozy's own — no invented Mixboard features.
Mixboard is an experimental AI concepting board from Google Labs. You start from a text prompt or a pre-populated example board, and it generates roughly fifteen image blocks; you then mix in your own uploads (device, Google Drive, or Google Photos), add AI-generated text blocks, and refine with natural-language edits plus one-click "regenerate" and "more like this" variations. Image generation and editing run on Nano Banana, Google's Gemini image model, and finished boards export as a PNG or a presentation and can be shared via a link. It launched as a U.S.-only public beta in September 2025, expanded to more than 180 countries on October 30, 2025, never left beta, and is being retired on September 28, 2026 with permanent deletion of all user data. That is the product: a free, fast visual-ideation surface that returns a downloadable board and stops there.
The first reason is unavoidable: the tool is going away. A workflow built on a product with a fixed deletion date is a workflow with an expiry date, and September 28, 2026 is close. Even if Mixboard did everything you needed, you would need somewhere durable to move to. The second reason is structural and was true before the shutdown. Mixboard has no content layer. It reframes nothing per feed, adds no captions, holds no brand voice or persona identity across pieces, does no one-idea-to-many fan-out into a carousel, blog, and newsletter, and has no scheduler and no publishing. It hands you a board of images and leaves the entire job of turning that into posts — designing, writing, formatting, scheduling, publishing — to you. For anyone whose actual bottleneck is "I need finished, on-brand content live across my platforms every week," Mixboard was never going to be the answer, and now it is not even going to be there.
| Feature | Google Mixboard | Kompozy | Note |
|---|---|---|---|
| Prompt-driven visual ideation / mood boards | Yes — its core strength | No — a content pipeline, not a brainstorming canvas | Mixboard wins outright on open-ended visual exploration. |
| Nano Banana natural-language image editing | Yes | Partial — Gemini face-lock + gpt-image generation | Mixboard is built around free-form Nano Banana editing; Kompozy uses image models to produce finished, on-brand assets. |
| Finished social formats (video, carousels, posts) | No — exports a PNG or presentation | Yes — 18 formats | Kompozy turns a concept into ready-to-publish posts; Mixboard stops at the board. |
| Persona / avatar video generation | No | Yes — HeyGen persona video, clips, VFX hooks | Mixboard is images only. |
| Brand voice & persona governance | No | Yes — Persona Brief + banned-word filters | Mixboard has no concept of your voice across pieces. |
| Scheduling & multi-platform publishing | No | Yes — nine destinations + autopilot | Mixboard cannot publish anywhere. |
| Durable, owned media storage | No — boards deleted September 28, 2026 | Yes — persisted to storage you own | The shutdown deletes everything; Kompozy keeps your library. |
| Price to start | Free (Labs beta) | Paid, from $99/mo | Mixboard wins on entry price — but it is free and ending, not free and durable. |
| Tier | Google Mixboard plan | Google Mixboard price | Kompozy plan | Kompozy price |
|---|---|---|---|---|
| Entry | Google Mixboard (Labs beta) | Free — but shutting down September 28, 2026 | Kompozy Starter | $99/mo (5,500 credits) |
| Mid | No paid Mixboard tier | N/A — Mixboard had no paid plan | Kompozy Pro | $299/mo (18,000 credits) |
| Top | No enterprise Mixboard tier | N/A | Kompozy Enterprise | Custom (sales-led) |
The Mixboard shutdown forces a decision anyway, so make it the right one: instead of finding another place to make boards you still cannot publish, move to the tool that does the part Mixboard never did. Kompozy is a content generation and publishing engine. Hand it the one concept image you settled on — the palette, the look, the product direction — and it renders the finished set: face-locked [Persona Photos](/glossary/persona-shorts), brand-exact [Carousels](/glossary/hyperframes) through HyperFrames, quote cards, blogs, newsletters, and HeyGen avatar video, all governed by one [Persona Brief](/glossary/persona-brief) so the batch reads as one creator.
Then it ships them. [Autopilot](/glossary/autopilot) schedules and publishes the whole set across the eight social platforms plus blog and email behind a per-post review, and every asset is persisted to durable storage you own — no beta, no deletion date. Mixboard helped you decide what it should look like and then handed you a PNG. Kompozy takes that decision and turns it into a published, on-brand week of content that is still there next year.
It depends on the job. For pure ideation, Google Pics (the Nano Banana workspace Google is keeping) or Canva stay in the same lane. To actually turn a concept into finished, published content — video, carousels, blogs, newsletters scheduled across platforms — a content engine like Kompozy is the alternative, because Mixboard never did that half and is shutting down anyway.
Google is shutting Mixboard down on September 28, 2026, after which all boards, images, and prompts are permanently deleted and shared links break. If you built anything on it you need to export your work and move to a tool that will still exist.
No, and that is the point. Mixboard is upstream ideation — a mood-board canvas. Kompozy is downstream production and publishing — it takes a decided concept and generates finished, on-brand posts across 18 formats, then schedules and publishes them across nine destinations. They sit on opposite ends of the workflow.
Mixboard was free because it produced nothing you could publish, and it deletes your work on September 28, 2026. Kompozy is paid because it replaces a stack — designer, copywriter, video tool, scheduler, publisher — and keeps your generated media in storage you own. You pay for finished, durable content, not a mood board.
Yes. Export the concept image you liked from Mixboard as a PNG, bring it into Kompozy as a brand reference, and Kompozy renders face-locked persona images, carousels, quote cards, blogs, newsletters, and video that match the direction — then schedules and publishes them across platforms.
