How Taplid got started

I was using AI coding agents to write and review code. After folding in the local review findings, I sent the resulting code changes to the OpenAI and Anthropic APIs for final independent code reviews. Taplid was not auditing Claude Code directly. It audited the reviews returned by those APIs against the actual code diff, requirements, and test evidence. I kept seeing confident review claims that were not supported by what had really changed in the code. Adding more AI reviewers helped, but it still left me with one probabilistic system judging another. I wanted a final quality gate that could check whether the review itself was evidence-backed and return a clear ALLOW, REVIEW, or BLOCK decision. That frustration became Taplid, a deterministic-first auditing layer for generated and structured output. I also added Next Steps in which the local agent could clearly act upon the code review and Taplid's audit.

Growing Taplid: what worked and what didn't

At its core, Taplid does one thing, it audits an output against the context it was supposed to follow. Because that applies to many users and workflows, I created focused landing pages for AI code review auditing, schema checking, response validation, and hallucination checking. This worked better than expected. Several pages began appearing in organic Google results, including a strong position for “AI schema checker.” It showed me that users respond better when the problem, input, and expected outcome are explained in language matching their workflow. Paid traffic initially flopped. I spent money on Google and Reddit ads that generated clicks but almost no completed audits. The targeting was too broad, and many visitors either were not relevant users or did not immediately understand what to enter. I learned that low-cost traffic has little value unless the visitor understands the product, reaches the landing page, and completes the core action.

What Taplid customers really think

The biggest early problem was that new users did not always understand what information Taplid needed. Some entered only the source material or context and left the example response unchanged. Others were unsure about the difference between the context, the optional prompt, and the response that Taplid was supposed to audit. The workflow was obvious to me because I had designed it, but that did not mean it was obvious to someone seeing the product for the first time. I responded by simplifying the terminology, moving the required Response field above the optional Prompt field, and clearly labeling it as the output being audited against the supplied context. I also improved the examples, landing-page explanations, and first-use guidance. In addition, I built better internal request history so I could inspect anonymous usage, identify where users became confused, and improve the interface based on real behavior rather than assumptions. The main lesson was that product clarity matters as much as technical capability.

What most people get wrong about API Testing Tools

Many people assume the answer to unreliable AI output is simply to ask another AI model to review it. That can help, but it often creates a chain where one probabilistic system is judging another probabilistic system. Both models can sound confident, repeat the same assumption, or miss the same issue. The real requirement is not another opinion. It is a controlled audit against the source of truth. Give Taplid the document, policy, code diff, test evidence, schema, specification, or other context, together with the output produced from it. Taplid checks whether that output follows the supplied source and flags unsupported claims, contradictions, missing requirements, and incorrect conclusions. AI is commonly involved, but the underlying problem is broader than AI. Any generated or structured output can drift from the evidence or rules it was meant to follow. Most people focus on how impressive the output sounds. The more important question is whether the output can be justified by the source material.

What's next for Taplid

Taplid is still at an early stage, so the next 6 to 12 months will focus on learning from real usage and refining the product around the workflows that provide the most value. The main target is enterprise teams that need reliable, auditable output validation for production systems, compliance, and internal governance. I also plan to continue supporting individual developers and smaller teams using Taplid for AI code reviews, schemas, policies, documents, and generated responses. The priority is not adding features for the sake of it. It is improving onboarding, integrations, audit quality, and deployment options so Taplid becomes a dependable quality gate inside real automated workflows.

Anthony's background

Before building Taplid, I had more than 25 years of professional experience and had spent over 10 years contracting as a software engineer, architect, and DevOps specialist for major multinational companies, including some of the world’s largest banks. My work involved designing, building, and supporting complex production systems where reliability, security, auditability, and compliance were essential. I had also built and operated my own online products and had extensive experience using AI-assisted development workflows. That combination gave me both the technical background to build Taplid and the practical understanding of why generated outputs need to be checked against their actual source material, requirements, and evidence before they are trusted or used.

Biggest lesson building Taplid

My biggest mistake was assuming that because the product workflow was obvious to me, it would also be obvious to new users. Some visitors did not understand what belonged in the context and response fields, while others left the sample response unchanged. I also began testing paid advertising before the onboarding experience was clear enough. This generated clicks without meaningful engagement or completed audits. I learned that increasing traffic does not solve confusion. Before spending money to attract users, the product must explain itself clearly and make the required actions unmistakable. I now inspect real usage, simplify the language, shorten demonstrations, improve examples, and validate the complete first-time user journey before trying to scale traffic.
I would launch a simpler version earlier, observe first-time users immediately, and improve onboarding before adding more features or paying to attract traffic. It's nice to have lots of features, but it is more important to deliver exactly what a customer needs.
