Why I Built LeemerChat: The AI Platform That ChatGPT Wishes It Was

Let's get real for a second. I'm Repath Khan, and I built LeemerChat because I was tired of switching between endless AI apps. Claude for writing, GPT for coding, Gemini for research—each great at something, none great at everything. So I created something better: one unified platform. Here's why, once you try LeemerChat, going back to ChatGPT feels like stepping backward.

Multiple Models, One Conversation

Here's the open secret in AI: not all models are created equal. Some excel at creative writing, others dominate coding or deep logic. At LeemerChat, we integrate all the best models—Claude 3.7 Sonnet, Gemini 2.5 Pro, GPT-4.1, LLaMA-4, Qwen-3, and even the cutting-edge Mistral Medium 3—into a single chat interface. You seamlessly switch between them in the middle of conversations, preserving your context. No resets, no friction.

Why does this matter? Because Claude 3.7 Sonnet consistently outperforms GPT models in creative tasks and coding efficiency. Because Gemini 2.5 Pro is our all-around superstar, excelling in every benchmark, from multimodal tasks to nuanced reasoning. And because GPT-4.1, with an incredible 1 million token context capacity, dwarfs ChatGPT's 128k token limit, letting you work with vastly larger documents and ideas without interruption.

The Insane Speed of Leemer Swift—Now Free to Use

Powerful AI shouldn't slow you down. Our custom Leemer Swift mode, powered by the new LLaMA-4 model, achieves lightning-fast inference speeds of over 2,900 to 3,000 tokens per second. That's not a typo. This makes Leemer Swift a whopping 20x faster than ChatGPT's GPT-4, which averages around 150 tokens per second.

Imagine typing a question and getting a detailed, accurate answer instantly—literally in the blink of an eye. This isn't just fast; it feels revolutionary. And the best part? Leemer Swift is completely free to use, right now, for everyone.

Specialized Models for Specialized Tasks

We recognize that every AI has its strength. Models like Qwen-3 shine in specific analytical tasks, while Mistral Medium 3, recently integrated into LeemerChat, excels in nuanced conversational flow. By offering a vast array of specialized AI models, LeemerChat empowers you to always have the perfect AI companion for your specific need, whether you're writing a novel, debugging complex code, or analyzing research data.

Privacy Matters—Seriously

Your privacy isn't just a feature—it's our priority. All your conversations and data are stored locally in your browser. Unlike ChatGPT, we never train our models on your conversations. Your thoughts remain yours, fully protected.

AI, Optimized for Real Life

From instant image generation using GPT Image-1 to transforming complex research into interactive HTML visualizations, LeemerChat is more than a chat—it's a toolkit designed to amplify your creativity, productivity, and enjoyment.

The Verdict? LeemerChat Changes How You Use AI

ChatGPT is good, but good enough isn't enough. If you're ready to experience what AI should really feel like—instantaneous, diverse, powerful, and deeply personal—LeemerChat is waiting for you.
