Lexica
Paid Last updated: September 2026AI image generator with the largest searchable prompt library in the industry
What is Lexica?
Lexica started as a prompt search engine, the largest public database of Stable Diffusion prompts and their generated images on the internet, and grew into a full AI image generator layered on top of that library. Its killer feature is still discoverability: you can search millions of real prompts submitted by real users, see exactly what each one produced, click any result to remix the prompt yourself, and adjust parameters from there. For anyone learning prompt engineering, this is an unmatched resource. No other AI art platform gives you this direct visibility into what actually works. On top of the library, Lexica runs its own Aperture model, a fine-tuned image generator focused on photorealistic and artistic outputs, alongside access to Stable Diffusion variants. There is no free plan: Lexica says the only way to generate images is by subscribing to a plan, and commercial use also requires a paid plan. Pricing is clean: Starter at $10/month (1,000 fast generations, personal commercial license), Pro at $30/month (3,000 fast generations, full commercial license, unlimited slow generations with daily cap), and Max at $60/month (7,000 fast generations, private images, full commercial license), or $8, $24, and $48 per month billed annually. Pro and Max users who exhaust fast generations are moved to the slow queue rather than cut off. Lexica is particularly popular with designers, content creators, and prompt engineers who want to learn by example, and with indie developers building AI-powered tools who need a searchable image source.

⚡ Quick Verdict
Prompt learners and visual designers who want to discover, remix, and refine prompts from a massive searchable library
Teams needing local model support, LoRAs, or the absolute cutting edge in visual quality
Starter $10/mo · Pro $30/mo · Max $60/mo ($8, $24, and $48/mo billed annually)
No. Lexica says the only way to generate images is by subscribing to a plan
Millions of searchable public prompts and the fastest way to learn what works in AI image generation
Trustpilot reviews since January 2026 report that image generation fails and support does not reply, and the generator trails Midjourney on maximum artistic polish
Bottom line: Lexica scores 4.3/5, and its searchable prompt library made it one of the best tools for learning AI prompting, but user reviews since January 2026 report that image generation fails, and there is no free plan to test it on. Do not pay for a year up front: if you still want to try it, take one month of Starter ($10/mo), or choose an alternative.
Pricing
No free plan: Lexica says the only way to generate images is by subscribing to a plan.
Starter, $10/month or $8/month billed annually: 1,000 fast generations per month, no slow generations, 2 concurrent fast jobs, public images, personal commercial license.
Pro, $30/month or $24/month billed annually: 3,000 fast generations per month, unlimited slow generations (with a daily cap), 3 concurrent fast jobs, public images, full commercial license.
Max, $60/month or $48/month billed annually: 7,000 fast generations per month, unlimited slow generations (with a daily cap), 3 concurrent fast jobs, private images, full commercial license.
Add-on credits: Additional fast generations can be purchased at $0.05 per generation. They never expire but require an active paid plan to use.
Annual billing: Every paid tier is 20% cheaper when billed yearly instead of monthly.
Commercial rights by company size: Lexica scopes the license to headcount. Starter covers solo commercial use, Pro covers companies of 2 to 5 people, and Max is required for companies of 5 or more. Images you generated on a paid plan stay licensed for commercial use even if you later cancel.
How credits are counted: each prompt submission consumes 4 image generation credits.

FAQ
Is Lexica free to use?
No. Lexica says the only way to generate images is by subscribing to a plan, as there is currently no free plan. Plans start at $10/month for Starter, or $8/month billed annually. The public prompt library has been free to search, but the homepage that hosts the search returned a server error when we checked in September 2026. Lexica's terms allow free personal use of its images, while commercial use requires a paid plan.
What is the Lexica prompt library?
The Lexica prompt library is a searchable database of millions of Stable Diffusion prompts that real users have submitted along with the exact images those prompts produced. You can search by keyword, artist name, style, or subject and see the prompt text, model, parameters, and result side-by-side. Clicking any image lets you instantly remix the prompt in the Lexica generator. It is the largest tool of its kind.
How much does Lexica cost?
Lexica has no free plan and three paid tiers: Starter at $10/month (1,000 fast generations, personal commercial license), Pro at $30/month (3,000 fast generations plus unlimited slow queue, full commercial license), and Max at $60/month (7,000 fast generations plus unlimited slow queue, private images, full commercial license). Billed annually, they cost $8, $24, and $48 per month. Additional fast generations can be purchased at $0.05 each. Because user reviews since January 2026 report that image generation fails, avoid paying for a year up front.
What is Lexica Aperture?
Aperture is Lexica's in-house image generation model, fine-tuned specifically for photorealistic and artistic outputs. It runs alongside Stable Diffusion variants inside the Lexica generator and is the default for many prompts. Aperture's strength is reliable photo-like results with less prompt engineering than base Stable Diffusion requires. The model is available on all paid plans; there is no free plan.
Can I use Lexica images commercially?
Yes, but only on paid plans, and Lexica ties the license to team size. The Starter plan ($10/month) grants a personal commercial license for individual creators, Pro ($30/month) covers teams of 2 to 5 people, and Max ($60/month) covers teams of 5 or more, both with a full commercial license. Images you create on a paid plan stay licensed for commercial use even if you later cancel. If you want to sell prints, use images in client work, or embed them in commercial products, you need at least Starter.
Lexica vs Midjourney, which is better?
Midjourney still produces better artistic polish on average and is the industry leader for illustration work. Lexica's edge is prompt discovery through its searchable library, but user reviews since January 2026 report that its image generation fails, and its homepage returned a server error when we checked in September 2026. For images you pay to generate, Midjourney is the more dependable choice today.
Does Lexica support private generations?
Yes, on the Max plan ($60/month, or $48/month billed annually). On Max, all your images are private unless you decide to share them, so they stay out of the public feed and the searchable library. Images created on Starter and Pro show up in Lexica's search, where other users may also use them. If you are working on confidential projects, Max is the tier to choose.
What happens when I hit the fast generation limit?
On Pro and Max plans, hitting your monthly fast generation cap does not cut you off: Lexica switches you to the slow queue, where generations stay unlimited up to a daily cap. Starter has no slow generations, so Starter users need to upgrade or buy extra fast generations, which cost $0.05 each, never expire, and require an active plan.
📋 Good to know
Sign up at lexica.art and subscribe to Starter, Pro, or Max on the account page before you generate anything, since there is no free plan.
On the Max plan, your images are private unless you choose to share them. Images created on Starter and Pro show up in Lexica's public search, where other users may also use them. Check Lexica's terms for full details.
There is no free plan to upgrade from, and user reviews report that generation fails, so test one month of Starter ($10/mo) before paying for a year. Pro ($30/mo) adds unlimited slow-queue generations and covers teams of 2 to 5; Max ($60/mo) adds private images and covers teams of 5 or more.
Very low. Browse prompts, remix what inspires you, generate. The prompt library makes learning AI art dramatically faster than starting from a blank box.
