Updated 8 November 2026. Every BlockGPT fact below is from blockgpt.ai's own pages, on the date given.
BlockGPT is an AI Minecraft build generator at blockgpt.ai: you describe a build or upload a picture and it gives you a schematic. If you're looking for an alternative, the two questions people ask first are whether it's free and whether it's legit, so those come first here, answered from its own pages.
We make Block Dreamer, one of the alternatives, so read the second half as written by one of the options.
Short answer: BlockGPT shows 5 previews a day free with no account, but a download needs a paid plan; its FAQ says a first build costs $1 for 24 hours, then $19 a month unless you cancel, and its pricing page offers a 14-day money-back guarantee. An alternative that works differently is Block Dreamer, where you build in a chat and change the build part by part.
Three things are called BlockGPT
Searching the name brings up three unrelated things: the build generator at blockgpt.ai, a Minecraft server plugin also called BlockGPT that adds a chat command for Google's Gemini, and a crypto token. This article is about the first.
Is BlockGPT free?
Partly. Its home page, read on 18 October 2026, says: "See your build free: 5 previews a day, no account. Java or Bedrock, download from $1." Its FAQ, read on 19 October 2026, explains the line:
- Free: 5 preview builds a day, with no account and no card. A preview is a render of what it made, "not a downloadable file".
- Also free: downloading builds other people have already made from its public gallery, with no account.
- Paid: downloading your own build. The FAQ says "Your first build costs $1, which gives you 24 hours with the full Standard allowance of 50 builds", which "then renews at $19 a month unless you cancel".
- Plans, from its pricing page on 19 October 2026: Basic $9 a month for 12 generations, Standard $19 for 50, Pro $49 for 200; paying yearly "save up to 49%". Pro includes commercial use; Basic and Standard are for personal use.
So the free part is the preview; a download starts with the $1 day its FAQ describes.
Is BlockGPT legit?
We can only tell you what its own pages say; whether that is enough is your call.
- Its terms, last updated 26 July 2026, name the operator as BlockGPT and say they are governed by the laws of Australia.
- Payments go through Stripe, according to the terms.
- Refunds: the pricing page says "We offer a 14-day money-back guarantee for all paid plans", and the terms say a full refund is available within 14 days of the first purchase, even if the service was used, and that payments after that are not refundable except where the law requires.
- Cancelling: the terms say you can cancel from your account settings at any time, and access usually continues to the end of the period you paid for.
- Its footer links to the terms, a privacy policy, a support page and a Discord.
If you take the $1 offer, the date to remember is 24 hours later, when it renews at $19 a month unless cancelled.
What BlockGPT does that Block Dreamer doesn't
To be fair to it, from its pages on 19 October 2026: BlockGPT takes a picture as well as words ("Upload a picture of a character, object, person or building"), exports .mcstructure for Bedrock and .schematic for Minecraft 1.12 and older beside .schem and .litematic, includes commercial use on its Pro plan, and lets anyone download its gallery free. Block Dreamer takes pictures too, up to four a message, but does none of the other three. Its FAQ also says its builds are "detailed enough for interior rooms, layered facades and roof detailing"; we have not generated one to check.
Block Dreamer, the alternative that builds in a chat
Block Dreamer is an AI Minecraft build agent: you describe a build in a chat, it makes it as a Java 1.21 building or figure with a 3D preview, a layer plan, a block list and downloads for vanilla (.mcfunction), WorldEdit (.schem) and Litematica (.litematic), and then changes it as you ask, keeping every version; it makes one build at a time, not whole cities or landscapes.
What it does differently is what happens after the first version. On 18 October 2026 we described a stone cottage in one sentence, then asked for a steeper roof, a covered porch with two lanterns, and, back on the first version, a ridge two blocks higher. Each came back as a new version, and every block below the roof stayed the same when only the roof was asked for. Any version can be put back on the stage and downloaded.
It decides whether your words describe a building or a figure. A building is written block by block with the rooms and furniture you name, which you can see by cutting it with the LAYER rail:
A figure, such as a statue or a dragon, is carved from a 3D model, which gives it a rounder shape and a hollow inside. We asked for "a dragon statue sitting on a rock, wings folded, about 60 blocks tall" and it came back exactly 60 tall, 6,878 blocks.
Every version downloads four ways, one of them a .mcfunction you run in a vanilla world with no mods:
Side by side
| BlockGPT (its pages, 18 and 19 Oct 2026) | Block Dreamer (8 Nov 2026) | |
|---|---|---|
| Starts from | words or a picture | words or pictures, in a chat |
| Free | 5 previews a day, no account, no download | an account's first build, with downloads |
| Paid | $1 for 24 hours, then $19 a month; plans $9, $19, $49 a month | plans $9.99, $19.99, $49.99 a month; packs from $5.99 |
| Files | .schem, .litematic, .schematic, .mcstructure | .mcfunction, .schem, .litematic |
| Bedrock file | yes, .mcstructure | no; build it from the layer plan |
| Change a build | edit the downloaded file yourself | ask in the chat, Quick or Thorough; every version kept |
| Rooms inside | its FAQ says yes | yes in buildings; figures are hollow |
| Refunds | 14-day money-back guarantee | case by case, per our terms; a step that fails gives its credits back |
Read across the rows: BlockGPT is the one if you need a Bedrock file, a .schematic for old versions or commercial use; Block Dreamer is the one if you want to keep working on the build after the first version, place it without mods, or know what the rooms hold before you build. Block Dreamer does not export a Bedrock file and has no block-by-block editor, and a figure can only be made again as a whole.
Other alternatives
Structmatic has a block editor and Bedrock export; SchemForge sells small blocky builds cheaply; BlockArchitect gives a signed-in account one free generation a day. Their prices and limits, each from its own pages, are in our comparison of AI Minecraft build generators.
If BlockGPT's previews showed you the build you want and you need it on Bedrock, it may be the right tool. If you want to talk a build into shape, describe it in Block Dreamer and change it in the chat; an account's first build is free.
