Your gameplay is fine. Your thumbnail is why they scroll past.
01A thumbnail that gets clicks takes hours in Photoshop — or a designer you pay every video.
02Generic AI tools don't know the Roblox look. You get realistic renders when you need blocky, high-saturation, troll-face energy.
03AI text comes out garbled — the one thing a thumbnail can't get wrong.
04Credit-based tools cap you and mark up the AI, so testing 10 versions of a thumbnail costs real money.
How it works
Idea to thumbnail in three steps.
No design skills, no prompt engineering. The Roblox and Fortnite styles are built in: 16:9, one clear subject, bold color, a readable title.
STEP 01
Get one free, then pick how to go on
Sign in, paste your game link and your first thumbnail is on us, no Gemini key (one per person, while today's free spots last). After that, Nexframe Credits are 40 thumbnails/month for $9.99/month - no key, cancel anytime - or generate on your own Gemini key: it needs billing enabled on that Google account, and Google bills you directly.
STEP 02
Describe & pick a style
Type your idea, choose Roblox or Fortnite. Use a preset — “Noob vs Pro”, “Day 1 vs Day 100” — or write your own.
STEP 03
Generate, edit, download
Get variants side by side. Tweak the text, swap an expression, upscale to 4K, and download — or turn it into a game icon.
The honest part
Unlimited — because you own the engine.
Other thumbnail tools sell you credits and mark up the AI. Every generation eats your balance, and testing versions gets expensive fast.
Nexframe charges $50/mo for the tool. The generation runs on your Gemini key, at Google's real cost — roughly $0.03-$0.13 a thumbnail, billed by Google, not us. Generate ten or ten thousand. Same $50.
Your key passes through only to reach Google. It's never logged, never stored, never used for anything else.
Built for the niche
Everything a Roblox thumbnail actually needs.
Roblox & Fortnite, tuned
Blocky avatars, troll grins, lava, studded baseplates — the look that gets clicked. One toggle switches the whole engine.
Real text layer
Editable text on top — font, color, outline — so your title is never the garbled mess AI usually produces.
Edit without regenerating
Change “DAY 100” to “DAY 365”, swap an expression, remove the boss — without redrawing the whole thumbnail.
Thumbnail → game icon
Turn any 16:9 into a clean 1:1 icon that doesn't distort or break — the thing every other tool gets wrong.
Game pass icons
512x512, cropped to the circle Roblox actually displays. The safe area is built into the prompt, not left to luck.
Variations on demand
Love one? Get four more like it. Finding the winner is iteration — this makes it fast.
4K upscale & download
Sharp at full resolution, in the exact size YouTube and Roblox want.
Game pass icons
Roblox crops pass icons to a circle. Most tools don't know that.
A pass icon is capped at 512x512 and displayed inside the circle inscribed in that square, so only a 362x362 box survives. Nexframe composes for that box and hands you the circular 512x512 PNG, corners already transparent.
Launching with 10 passes? One line each, one style, about 32 seconds - and you only pay for the ones that come out.

- Generating needs a Gemini key with billing enabled on your Google account. Google bills you about $0.03-$0.13 per thumbnail, directly.
- When the 3 days end, nothing is charged automatically: the trial never asks for a card. To keep generating, you subscribe, only if you want.
Questions
Before you ask.
What's a Gemini key, and is it safe?+
It is an API key from Google AI Studio - two clicks to create, and free to create. It is how you pay Google directly for the image generation. Your key stays in your browser, goes out in the request header, and is used and discarded - the server never stores it and never logs it.
Do I need to put a credit card on Google?+
For your own key, yes, and it is better to know now. Creating the key is free, but Google's free tier does not cover image generation - every image model is listed as "Not available" on it - so the key only starts producing images once billing is enabled on your Google account. From then on you pay Google directly, roughly $0.03 to $0.13 per thumbnail. Nexframe's 3-day trial never asks for a card, and nothing is charged when it ends: our price is for the tool, and Google's bill is Google's. Nexframe Credits skip all of this: they generate on our side, with no key and no Google billing.
What if I can't get a Gemini key?+
Your first thumbnail needs no key at all (one per person, while today's free spots last), so you can see the result before deciding. After that, Nexframe Credits work with no key: 40 thumbnails/month for $9.99/month, generated on our side. The unlimited plan does need your own key. AI Studio is unavailable in some countries and blocked on many company accounts. If you are not sure whether yours is one of those cases, ask in the Discord before signing up - it costs you nothing to find out first.
So what does generation actually cost me?+
On the plan, roughly $0.03 to $0.13 per thumbnail, depending on model and resolution, billed by Google straight to your account. The $50/mo is only for the tool, with no markup on generation. Nexframe Credits are the no-key convenience: 40 thumbnails/month for $9.99/month ($0.25 each), priced per thumbnail by us instead of at Google's cost, because we pay Google for the generation.
Is there a community?+
Yes. New presets, fixes and what is coming next get posted in the Discord first, and it is also where to ask when a thumbnail is not landing and you cannot tell why.
Do I need design or prompt skills?+
No. Pick a preset, type a rough idea, generate. The Roblox and Fortnite styles are already tuned - you do not write the technical prompt, the engine does.
Does it do both Roblox and Fortnite?+
Yes - one toggle switches the entire style engine, including presets, character look, and icon rules.
Can I cancel?+
Anytime, in one click. You keep access until the end of the period you already paid for. The Nexframe Credits plan cancels the same way: your monthly credits stay until the period you paid for ends, and it never renews again.
