Feature Comparison
Agent to Agent Testing Platform
Automated Scenario Generation
The platform automatically generates diverse testing scenarios, simulating various chat, voice, hybrid, and phone interactions. This feature ensures a comprehensive evaluation of AI agents across multiple contexts, enabling accurate performance assessments.
True Multi-Modal Understanding
Agent to Agent Testing Platform allows users to define detailed requirements or upload various input types, including images, audio, and video. This capability ensures that the AI agent can handle real-world scenarios, providing a complete understanding of agent behavior beyond text-based inputs.
Autonomous Test Scenario Generation
Users can access a library of hundreds of pre-defined testing scenarios or create custom ones tailored to specific AI agents. This flexibility enables thorough assessments of different functionalities, such as personality tone and intent recognition, ensuring well-rounded testing coverage.

The platform offers end-to-end regression testing, providing insights into potential risks associated with AI agents. This feature highlights areas of concern, allowing teams to prioritize critical issues and optimize their testing efforts for better reliability.
Doodle Duel
Instant Play, No Friction
Doodle Duel is built for immediate engagement. There is no requirement to download software, create an account, or sign in with an email. You can begin playing within seconds by visiting the website. To start a game with friends, you simply create a room, receive a shareable code, and your friends can join by entering that code on their own devices. This eliminates all traditional barriers to starting a game, making spontaneous play sessions effortless and straightforward for everyone involved.
AI-Powered Judging System
The game's defining feature is its use of advanced AI models from Google Gemini or OpenAI to act as an impartial judge. After each drawing round, the AI analyzes every submission. It does not judge based on artistic perfection but evaluates specific, objective criteria: how accurately the drawing represents the given prompt, the creativity of the interpretation, and the style employed. This provides fair and consistent feedback for every player, ensuring the winner is determined by the AI's analysis rather than a subjective popularity vote among friends.
Flexible Game Modes
Doodle Duel offers two distinct ways to play, catering to different preferences. For social, chaotic fun, the Multiplayer Duel mode allows you to create rooms and compete with friends in real-time. For a personal challenge, the Solo Arcade mode presents 50 levels of increasing difficulty where you must beat score thresholds, manage a limited number of lives, and climb global leaderboards. This dual-structure ensures the game provides value whether you are alone or in a group.
Real-Time Synchronized Play
The multiplayer experience is designed for seamless, live interaction. When a round starts, all players in the room receive the same prompt simultaneously and work against the same 60-second timer. Everyone can see the countdown, creating a shared sense of urgency and excitement. Once time is up, all drawings are submitted and judged by the AI at once, with results displayed to the entire group in real time. This synchronization is fundamental to creating an engaging, party-game atmosphere where everyone participates together.

Doodle Duel
Virtual Social Gatherings and Parties
Doodle Duel is an excellent activity for online parties or casual hangouts with friends and family who are geographically separated. By creating a room and sharing the code, you can quickly bring a group together for a session of lighthearted competition and shared laughter. The game's simplicity and the humor often found in the AI's feedback serve as a fantastic icebreaker and a source of collective entertainment, making virtual gatherings more interactive and memorable.
Classroom Engagement and Icebreakers
Educators can use Doodle Duel as a creative tool for classroom engagement, team-building, or as a fun break. The game encourages quick thinking, interpretation, and visual communication skills. A teacher can create a room, share the code with students, and use prompts related to lesson topics or general themes. It provides a non-intimidating way for students to participate, as artistic skill is not the primary focus, and the AI's objective judging removes social pressure.
Solo Creativity and Skill Practice
For individuals looking to practice drawing, spark creativity, or simply pass time in an entertaining way, the Solo Arcade mode is ideal. It provides a structured, challenging environment with specific prompts and score goals. Players can work through levels at their own pace, trying to improve their scores and climb the leaderboards. This use case turns Doodle Duel into a personal creativity gym, helping users hone their ability to conceptualize and sketch ideas quickly.
Corporate Team Building Events
Companies can utilize Doodle Duel during remote or in-person team-building sessions. The game promotes creative thinking, friendly competition, and collaboration in a low-stakes, fun environment. It requires no special skills from participants, ensuring everyone can join on an equal footing. The shared experience of drawing and reacting to the AI's often humorous critiques can help break down barriers, improve team morale, and foster a more connected and relaxed workplace culture.
Overview
About Agent to Agent Testing Platform
Agent to Agent Testing Platform is an innovative AI-native quality assurance framework specifically designed to assess the behavior of AI agents in real-world scenarios. As AI systems advance towards greater autonomy, traditional QA methodologies, which primarily focus on static software, fail to meet the demands of dynamic AI interactions. This platform offers enterprises a comprehensive solution for validating AI agents, such as chatbots, voice assistants, and phone caller agents, ensuring they function reliably and effectively before deployment. By evaluating multi-turn conversations across various modalities, it helps organizations identify issues related to bias, toxicity, and hallucinations, among other critical metrics. The platform's unique multi-agent test generation and autonomous synthetic user testing capabilities allow for extensive exploration of edge cases and long-tail failures, ensuring a robust assessment of AI performance.
About Doodle Duel
Doodle Duel is a real-time online drawing game that combines creativity with friendly competition. At its core, the game is about translating ideas into sketches under time pressure and having those drawings evaluated by an impartial artificial intelligence judge. The process is straightforward: players receive a common prompt, have 60 seconds to draw their interpretation, and then an AI system powered by Google Gemini or OpenAI analyzes each submission. It scores the doodles based on objective criteria like accuracy to the prompt, creativity, and artistic style to declare a winner for each round. This fundamental gameplay loop removes the barrier of artistic skill, making the experience accessible and fun for both seasoned sketchers and complete beginners.
The game is designed for social play and instant accessibility. It requires no user accounts, downloads, or installations. To start, one player simply creates a virtual room, generating a unique code to share with friends. Up to four players can join for free, with a Pro upgrade allowing rooms of up to 30 participants. This makes Doodle Duel an ideal digital activity for parties, family gatherings, online hangouts, or classroom icebreakers. Beyond multiplayer, a Solo Arcade mode offers a single-player challenge with levels and leaderboards. The primary value proposition is clear: immediate, frictionless fun that sparks laughter and creativity through a unique blend of human imagination and AI-powered judgment, all directly in your web browser.
