About Merlio
What Is Merlio
Merlio is a web app that works as an AI model aggregator, bundling dozens of premium models into one dashboard. Instead of paying for ChatGPT Plus, Claude Pro and Midjourney separately, you get a shared pool of credits that you spend across chat, image, video and voice tools. The company says more than 277,000 people use it, and it markets the platform on cost: a single subscription that replaces a stack of $20-a-month tools.
The pitch is simple. Most people juggle several AI accounts, and each one bills you whether you use it that month or not. Merlio turns that into one bill and one login, then adds a feature the separate apps don't have: you can run the same prompt through several models side by side and keep the answer that works best. For coding you might lean on GPT-4, for long writing Claude, for images FLUX.
Two limits matter before you sign up. You don't own the underlying models, so when you hit your monthly credit ceiling you wait or pay more, even on the top plan. And it's a subscription aggregator, not a training platform, so there's nothing here for anyone who wants to fine-tune a model or work with raw API access.
Getting Started
- Create an account on merlio.app, which takes an email and no credit card for the free tier
- Pick a plan, or stay on the free entry point to test a handful of models first
- Open the chat panel, choose a model from the dropdown and type your prompt
- Compare two models side by side, then switch to the image or video tab to generate visuals from the same workspace

Key features
40+ Models Behind One Login
Merlio gathers text, image, video and voice models into a single account. You get GPT-4, Claude, Gemini, DeepSeek, Mistral and Llama on the text side, FLUX, Stable Diffusion, Ideogram, Leonardo and Nano Banana for images, plus Veo, Seedance and Pixverse for video. The point is access. You stop managing five logins and five bills and work from one dashboard.
Side-by-Side Model Comparison
The standout feature is the ability to send one prompt to two models at once and read both answers next to each other. That matters most when you're unsure which model fits a task. A coder can see whether Claude or GPT-4 gives cleaner output before picking one to rely on, and a writer can compare tone across two systems in seconds.
Image and Video Generation
Beyond chat, Merlio builds in an AI image generator and an AI video generator in one studio. You describe a scene and generate images through the supported models, then refine them with editing and enhancement tools. Video generation covers shorter clips through models like Veo and Seedance. Every plan carries a commercial license, so output you create is clear for client and business work.
Smart Tools For Daily Work
The platform layers practical tools on top of the models. Real-time web search pulls fresh information into an answer, file upload and PDF analysis let you question a document, and voice input saves typing. A code interpreter runs snippets without leaving the page, which helps when you're testing a fix mid-conversation.
Credit-Based Access Across Plans
Instead of separate limits per tool, Merlio uses one credit pool that you spend across everything. The Starter plan covers roughly 750 HD images or 2,000+ messages a month, Creator raises that to about 2,300 images or 6,000+ messages, and Pro reaches around 3,800 images or 10,000+ messages. Images and messages draw from the same balance, so heavy image use eats into chat and the other way around.
Bring Your Own API Keys
Every paid plan lets you plug in your own API keys from providers you already pay for. If you have access to a model through another account, you can route it through Merlio without buying a second subscription. That option is rare among all-in-one hubs and gives power users a way around credit limits.
Team and Enterprise Options
Businesses get a shared credit pool so a whole team draws from one balance, along with custom volume pricing and priority support. The Pro tier adds early access to new models and 4K image quality, which matters for agencies that need to ship at higher resolution.
Pros and cons
Pros
- One subscription and one login replace several separate AI bills, with the entry plan under $10 a month
- Side-by-side comparison makes it easy to pick the right model for a task instead of guessing
- Text, image, video and voice models share one workspace and one credit pool
- Commercial license is included on every plan, so client work is covered
- Bringing your own API keys adds flexibility past the monthly credit ceiling
Cons
- Credits are pooled, so heavy image generation cuts into the messages you have left for chat
- You don't control the underlying models, so a model can change or disappear without your input
- The top plan still runs into credit limits, which means extra spending if you work at high volume
- It aggregates models rather than training them, so there's nothing for anyone who needs fine-tuning or raw API access

The product is still in beta, so access runs through a waitlist or an invite. Paid plans aren't published yet.
Aiml API
AIMLAPI OÜ · OtherAiml API is a unified AI model API that puts more than 1000 models from OpenAI, Google, Anthropic, and others behind one endpoint and one bill. You write code against a single OpenAI-compatible schema, then switch between chat, image, video, and audio models by changing a model string. It suits developers and small teams who want multi-model access without juggling a dozen separate provider accounts, and it removes the usual billing headache that comes with testing several vendors. One key covers it all.
