FAQs
We cover the full process, from problem analysis and AI architecture to development, deployment, and support. If you're not sure what kind of AI solution fits your case, we’ll guide you.
Absolutely. We can integrate or fine-tune existing models (including LLMs) and build missing parts around them from UI to backend and MLOps.
If you have data - great. If not, we can help define data requirements, assist with collection strategies, or work with public/open datasets when appropriate.
We work with modern AI stacks & tools incl. prompt engineering techniques, RAG pipelines, agentic workflows, tools like OpenAI GPT, Anthropic Claude, Gemini and open-source orchestration tools like n8n. We also use frameworks such as Cursor, Windsurf, v0, Bolt, and Lovable depending on your needs.
Yes, our service includes production deployment, MLOps setup, system integration, and support.
Yes, and we offer extended support options if needed.
If needed - yes. We have in-house designers and frontend developers and can build full interfaces around the AI.
We don’t take on projects related to gambling, dating, adult content, or unethical use of AI.
Absolutely. We take client confidentiality seriously and are happy to sign an NDA before discussing sensitive project details.
