Lizzy AI
AI-powered interview screening platform with real-time avatars
Lizzy AI is a web-based interview screening platform that enables candidates to complete first-round interviews through an AI-powered avatar, supporting early-stage hiring by automating initial screening while preserving structured, consistent evaluation across roles and candidates.
Real-Time AI Interviews with 3D Avatar
Live interview sessions powered by OpenAI Realtime, enhanced with a realistic 3D AI avatar to support visual interaction during interviews.
Interview Results, Transcripts & Scoring Dashboard
Centralised dashboard for reviewing interview transcripts, scores, and structured evaluation outcomes.
Iterative AI Testing & Proof-of-Concept Development
Multiple POC iterations focused on testing AI interview behaviour, grading logic, and interview flow using real candidates.
The challenge
For Lizzy AI, the challenge was to bring an AI-led screening concept to life in a way that felt credible, scalable, and ready for real hiring scenarios, combining real-time AI interviews, visual interaction through a 3D avatar, and structured evaluation into a single web platform.
For Wolfpack Digital, the challenge was to design and build a reliable web application that could support live AI interactions, interview scheduling, transcription, and scoring, while iterating quickly through multiple proof-of-concept versions to test AI behaviour, interview flow, and grading logic with real candidates before investment.
The solution
Wolfpack Digital designed and developed a web-based platform that allows recruiters to create, manage, and schedule AI-assisted interviews across multiple positions, while giving candidates a smooth, guided interview experience.
The solution integrates real-time AI interviewing capabilities powered by OpenAI Realtime, combined with a realistic 3D AI avatar for visual interviewer support. Interview sessions generate real-time transcripts and structured scoring outputs, all accessible through a dedicated management dashboard.
The platform was developed iteratively through multiple proof-of-concept phases, with AI interview flows, grading logic, and avatar interactions tested using actual hiring leads and real candidates prior to investment.
This approach allowed Lizzy AI to validate the product in real-world hiring scenarios and refine the experience based on live feedback before scaling further.
As the product matured, Wolfpack Digital also supported the technical handover and early team hiring to ensure a smooth transition from proof-of-concept to internal ownership.
