Feature Comparison
Agent to Agent Testing Platform
Autonomous Multi-Agent Test Generation
The platform employs a team of over 17 specialized AI agents to autonomously create diverse and complex test scenarios. These agents act as synthetic users, generating a vast array of conversational paths, edge cases, and long-tail interaction patterns that would be impractical to script manually. This ensures comprehensive coverage and uncovers failures that human testers are likely to miss.
True Multi-Modal Understanding and Testing
Go beyond text-based validation. The platform allows you to define requirements or upload PRDs (Product Requirement Documents) that include diverse inputs like images, audio, and video. It tests the AI agent's ability to understand and respond appropriately to these multi-modal inputs, accurately mirroring complex real-world user scenarios and interactions.
Diverse Persona-Based Testing
Simulate a wide spectrum of real human users by leveraging a library of diverse personas, such as an International Caller or a Digital Novice. This feature ensures your AI agent is tested against different user behaviors, accents, technical proficiencies, and needs, guaranteeing it performs effectively and empathetically for your entire user base, not just a homogeneous group.
Regression Testing with Intelligent Risk Scoring
Perform end-to-end regression testing for your AI agent with clear, prioritized insights. The platform provides a risk score that highlights potential areas of concern based on test results.

Advanced Pattern Recognition
This feature allows you to input complex word patterns with precision. You can use dots or question marks for unique unknown letters and, crucially, use numbers to denote repeated unknown letters within the same pattern. For instance, inputting "112.2" tells the solver to look for five-letter words where the first two letters are the same, the third is different, and the last two letters are the same as each other (like "llama"). This sophisticated logic mirrors the puzzle's constraints, ensuring the suggested words perfectly fit the structural clues you've identified.
Dual Solving Modes: Single & Multi-Pattern
The solver offers two distinct operational modes to match your puzzle-solving stage. The Single Pattern mode is perfect for isolating and cracking individual troublesome words. The powerful Multi-Pattern mode allows you to enter two word patterns simultaneously, solving them side-by-side. This is invaluable when the words share common number/letter relationships, enabling you to cross-reference results and identify consistent letter mappings across the entire puzzle grid much faster than working on words in isolation.
Tiered Difficulty Dictionaries
Understanding that not all puzzles or solvers are the same, the tool provides three curated dictionary sizes. You can select the "Easy" list (20k common words) for simpler puzzles, the "Normal" list (115k words) for standard challenges, or the comprehensive "Hard" list (260k words) for the most difficult codewords that may include obscure vocabulary. This feature lets you tailor the solver's suggestions to the appropriate difficulty level, preventing overwhelming lists on easy puzzles or missing possibilities on hard ones.
Community-Powered Word Database
The solver is built to improve continuously with the help of its users. If you encounter a valid word that isn't found in the current database during your puzzle solving, you have the option to submit it for inclusion. This community-driven approach ensures the tool's coverage expands over time, becoming more robust and accurate for all players. It transforms the tool from a static resource into a living, evolving asset for the codeword community.
Use Cases
Agent to Agent Testing Platform
Pre-Production Validation of Customer Service Bots
Before launching a new customer support chatbot or voice assistant, enterprises can use the platform to simulate thousands of customer interactions. This validates intent recognition, escalation logic, policy adherence (e.g., data privacy), and the overall conversational flow, ensuring the agent is ready for live deployment and reduces the risk of brand-damaging failures.
Ensuring Compliance and Reducing Toxicity/Bias
Organizations can proactively test AI agents for unintended bias, toxic responses, or compliance violations. By generating tests from diverse personas and checking for policy breaches, the platform helps mitigate legal, ethical, and reputational risks, ensuring AI interactions are safe, fair, and aligned with corporate and regulatory standards.
Continuous Testing for Agentic AI Pipelines
Integrate the platform into CI/CD pipelines for continuous validation of AI agents. Every time an agent's model, prompts, or knowledge base is updated, autonomous regression tests can run at scale to immediately detect regressions in performance, accuracy, or reasoning, maintaining high quality through rapid development cycles.
Performance Benchmarking Across Modalities
Compare and benchmark the performance of different AI agent models or configurations across chat, voice, and phone modalities. The platform provides detailed, consistent metrics on effectiveness, accuracy, empathy, and professionalism, enabling data-driven decisions to select and optimize the best agent for specific use cases.

Breaking Through a Mental Block
Every solver reaches a point where they stare at a partially completed grid, unable to see the next logical step. Instead of resorting to random guesses that can derail the entire puzzle, you can input the pattern of the most promising unsolved word. The solver provides a shortlist of candidates, which often immediately reveals the correct letter or provides the clue needed to make a new connection elsewhere on the grid, getting your momentum back instantly.
Verifying Deductions with Confidence
After deducing that a certain number might represent a specific letter (like 'E' or 'S'), you can use the solver to test your hypothesis. Input a word pattern that includes this proposed mapping. If plausible words appear in the results, it reinforces your deduction. If no sensible words are found, it signals that your assumption may be incorrect, allowing you to re-evaluate without wasting time building on a faulty foundation.
Solving Interconnected Word Clues
In codewords, the power comes from letter mappings that apply grid-wide. The Multi-Pattern solving mode is specifically designed for this. When you have two words that intersect or share several common numbered cells, inputting both patterns together allows the solver to find word pairs that satisfy both structures simultaneously. This is exceptionally powerful for unlocking tightly linked sections of the puzzle that are difficult to solve independently.
Learning and Improving Solving Techniques
For newer players, the solver is an excellent educational tool. By experimenting with different pattern inputs and observing the results from various dictionary tiers, you can develop a better intuition for word structures, common letter patterns, and vocabulary. It helps you understand why a certain word is the only possible fit, thereby improving your independent solving skills over time.

Frequently Asked Questions
Agent to Agent Testing Platform FAQ
What makes Agent to Agent Testing different from traditional QA?
Traditional QA is built for deterministic, static software with predictable outputs. AI agents are probabilistic, dynamic, and their behavior evolves through conversation. This platform is AI-native, using other AI agents to test these non-linear, multi-turn interactions for nuances like reasoning, tone, and context-handling that scripted tests cannot evaluate.
What types of AI agents can be tested with this platform?
The platform is designed to test a wide range of AI-powered conversational agents. This includes text-based chatbots, voice assistants (like IVR systems), phone caller agents, and hybrid agents that operate across multiple modalities (text, voice, image). It validates the full agentic system, not just the underlying LLM.
How does the platform generate relevant test scenarios?
It uses a suite of specialized AI agents (e.g., a Personality Tone Agent, Data Privacy Agent) to autonomously create test scenarios. You can also access a pre-built library of hundreds of scenarios or create custom ones by defining requirements or uploading documents (PRDs), ensuring tests are tailored to your agent's specific functions and expected user interactions.

Code Word Solver - Missing Words Finder FAQ
How do I input a pattern for a word with repeated unknown letters?
To indicate repeated unknown letters within a single word pattern, you use the same number for each instance of the same unknown letter. For example, if you know a five-letter word has the first and second letters the same, and the fourth and fifth letters the same, you would input "11.22". The solver will then only return words that match this specific repetition structure, such as "llama" or "daddy".
What is the difference between the Easy, Normal, and Hard dictionaries?
The dictionaries differ in size and word commonality. The "Easy" dictionary contains approximately 20,000 of the most common words, ideal for beginner puzzles. The "Normal" dictionary has about 115,000 words, suitable for standard newspaper or magazine codewords. The "Hard" dictionary, with around 260,000 words, includes more obscure and less frequently used vocabulary, making it necessary for advanced or cryptic-style codeword puzzles.
Can I use the solver for an entire puzzle grid at once?
No, the Code Word Solver is designed to assist with individual words or linked word pairs, not to solve an entire grid automatically. Its purpose is to provide targeted help where you are stuck, allowing you to maintain agency over the solving process. You use it to find candidates for specific words based on the letter patterns you have uncovered, which then helps you deduce number-to-letter mappings for the rest of the puzzle.
What should I do if the solver doesn't find the word I know is correct?
First, double-check that you have entered the pattern correctly, including the proper use of numbers for repeated letters. If the pattern is correct, the word may not be present in your currently selected dictionary. Try switching to a larger dictionary (e.g., from Normal to Hard). If it's still missing, you can use the "Submit a new word or definition" feature to contribute the word to the community database for future use.
