About LinguaChats.ai
Specialized AI writing models for every writing need. Empowering creators, journalists, and businesses with purpose-built models behind one simple API.
Our Mission
At LinguaChats.ai, we believe that specialized AI models deliver superior results. Our mission is to provide writers, creators, and businesses with specialized writing models purpose-built for specific use cases—from creative fiction to technical documentation.
Each of our branded models pairs expert-tuned instructions with a proven open-source base model to excel in its domain. Buy credits once, spend them at your own pace, and access specialized models that truly understand your craft.
Our Story
LinguaChats.ai is built by Xotic Tech OÜ, a small team of writers and engineers in Estonia who recognized that general-purpose LLMs often fall short for specialized writing tasks. After experiencing the limitations of one-size-fits-all prompting, we knew there had to be a better approach.
Our approach: give leading open-source models—Llama 3.3 70B, Gemma 4 26B, and Llama 3.1 8B—carefully crafted, expert-tuned instructions for a single craft. Lyra is built for creative fiction, Echo for journalistic standards, and Sage for technical writing, so each model brings its own voice and focus without you having to engineer prompts from scratch.
We launched the platform in July 2026 with 8 specialized models—from Prism for marketing copy to Atlas for long-form content—with Ember and Cipher coming soon, all available through one OpenAI-compatible API.
