Mesut Ertas
About this gig
I build AI video avatar assistants with talking characters for your website.
I create interactive AI avatars that speak, respond and engage your users in real time. Whether you need a single talking avatar or a full multi-character assistant platform, I deliver a working, production-ready solution.
What I offer:
- AI video avatars with realistic lip-sync (D-ID)
- Conversational AI powered by OpenAI (GPT)
- Natural voice with Microsoft Azure Neural text-to-speech
- Custom characters with your own script and personality
- Multi-language support, including Turkish
My featured project AI Video Assistant:
A working AI video avatar assistant with a realistic, human-like character that talks in real time. It combines D-ID video avatars, OpenAI (GPT) conversational AI, and Microsoft Azure Neural text-to-speech, with a clean chat interface, audio playback, and both Turkish and English support. You can try it live in my gallery.
How it works:
- You share your idea, brand and what the avatar should do
- I build the avatar, voice and AI logic
- You review, I refine, you get a working assistant
Please message me before ordering so we can plan the best approach for your project.

Languages
Turkish, English
I build AI-powered web applications: chatbots and assistants powered by OpenAI and Anthropic (Claude) APIs, plus full-stack development with React, Next.js, TypeScript and Node.js. I integrate large language models, speech (text-to-speech / speech-to-text), and AI video avatars into production-ready apps. My featured project, CLIMAX AI, is a full-stack AI video avatar assistant with four interactive characters. I focus on clean, working solutions delivered end to end.

FAQ
Do I need my own OpenAI and Azure API keys?
Yes, you provide the API keys for OpenAI and Azure Speech. This keeps you in control of your accounts and usage costs. I will guide you through getting them if needed.
Can I choose the avatar's face and voice?
Yes. You can pick the avatar character and the voice (including Turkish voices). Custom characters and branding are included from the Standard package.
Does the avatar really talk in real time?
Yes. The avatar speaks the AI responses with lip-sync using D-ID, and users can also switch to audio-only mode. You can try the live demo in my gallery.
What languages are supported?
The assistant works in multiple languages, including Turkish and English. Multi-language support is included in the Premium package.
What do you need from me to start?
Your website details, the API keys, a short description of what the avatar should do, and its tone and personality. Message me before ordering so we can plan the scope.
