24 alternatives to Quell's UAT AI Agent Platform

After years of frustration dealing with slow, costly, and error-prone manual User Acceptance Testing (UAT) at fintechs, I built Quell—-a platform that auto-generates and executes UAT test cases using cross-functional AI experts (e.g. compliance, UX, operations, QA). Quell integrates seamlessly into workflows (Jira, Linear, GitHub), cuts down manual UAT process time by ~80%. I’m excited to get your feedback and answer any questions.

    Hi, I'm Daniel, CEO of QA.tech. We've spent the past 18 months developing a cool tool that allows you to run end-to-end tests on any web application using natural language. Check it out and let us know what you think! I used to be a CTO at a B2C marketplace and was taken aback that all qa agencies we talked to wanted to create a custom suite of tests from scratch. Even though we were essentially a e-com with the same functionality as everyone else. Why weren't there any best practices? Some time later my co-founders and I had moved on and were looking for the next thing to do. AI agents…

    Hi HN — I’m Kimi, founder of Aident AI. A couple years ago, I cold-started a startup and tried to automate my outreach pipeline with a patchwork: RPA + Zapier + "just some ChatGPT". It worked… until it didn’t. Every time I tweaked the strategy, the automation snapped. The system wasn’t built for change — it was built for wiring. And that’s when it hit me: AI is finally smart enough to do real work, but we still don’t have a clean way to communicate the work to it: Drag-and-drop flows are too rigid; Scripts are too fragile; Prompts are too ephemeral. I kept thinking: why can’t automation be…

    I built an AI agent that can do mobile app QA after working at Google for years and waiting weeks for QA results. It runs on real devices and uses an ensemble of agents (including computer use) to test like a human. Happy to answer questions and hope it helps app devs ship faster without bugs!

    Fabraix▲196

    We built Adversarial Cost to Exploit (ACE), a benchmark that measures the token expenditure an autonomous adversary must invest to breach an LLM agent. Instead of binary pass/fail, ACE quantifies adversarial effort in dollars, enabling game-theoretic analysis of when an attack is economically rational. We tested six budget-tier models (Gemini Flash-Lite, DeepSeek v3.2, Mistral Small 4, Grok 4.1 Fast, GPT-5.4 Nano, Claude Haiku 4.5) with identical agent configs and an autonomous red-teaming attacker. Haiku 4.5 was an order of magnitude harder to break than every other model; $10.21 mean…

    I built AutoThink, a technique that makes local LLMs reason more efficiently by adaptively allocating computational resources based on query complexity. The core idea: instead of giving every query the same "thinking time," classify queries as HIGH or LOW complexity and allocate thinking tokens accordingly. Complex reasoning gets 70-90% of tokens, simple queries get 20-40%. I also implemented steering vectors derived from Pivotal Token Search (originally from Microsoft's Phi-4 paper) that guide the model's reasoning patterns during generation. These vectors encourage behaviors like numerical…

    Today we are launching YourGPT 2.0, an update focused on making support, sales, and operational workflows work together more smoothly in one system. This release improves how workflows are built, how the platform connects to external tools, and how context is maintained across long, multi-channel interactions. AI Studio now makes it much easier to create and refine workflows. You can describe the process you want in natural language and the system generates the full workflow for you. It can also help debug issues by showing what happened at each step and explaining where things went off…
