If you can type a sentence, you can probably ship an AI-powered feature today. The real divide is no longer coding skills but how precisely you tell chatbots what to build. That shift becomes obvious when you try to develop one app with three different Artificial Intelligence copilots.
How a frustrated reader turned to vibe coding with chatbots
The story starts with a simple irritation: e-readers that still behave like offline PDFs. Many people read on a Kindle, yet cannot seamlessly switch between reading text and listening with synced highlights. Native mobile apps support this fluid experience, but dedicated devices often lag behind, despite two decades of hardware evolution.
That annoyance pushed a developer, Alex, to experiment with “vibe coding” as a new style of App Development. Instead of opening an IDE and writing boilerplate, Alex opened three Chatbots in parallel: Gemini, Claude and ChatGPT. The goal was not a production SaaS, but a serious prototype that might be used every evening. The experiment: describe a rich e-reading experience in natural language and see how far AI Integration alone could go.

Tome Reader as a sandbox for AI-powered user experience
Alex named the project “Tome Reader”. The idea was straightforward yet ambitious: a single-page web app that could run from one HTML file in any modern browser. Users would paste text or upload a PDF or EPUB, then let the app read aloud with real-time highlighting, dynamic background music and sound or visual effects triggered by specific words such as “door”, “thunder” or “ocean”.
Behind that playful premise hid serious questions about User Experience and Conversation Design with machines. Could Natural Language Processing instructions alone coordinate text-to-speech, audio mixing, event triggers and file parsing? Would three different models interpret the same specification consistently? Tome Reader became the perfect testbed for these questions and for evaluating Success Factors beyond raw model intelligence.
Building Tome Reader with Gemini, Claude and ChatGPT
Instead of writing one giant prompt and pasting it everywhere, Alex used an iterative Prompt Engineering workflow. Gemini went first. Alex described the minimal app: load text, display it cleanly, use browser speech synthesis, highlight words as they are spoken. Once a basic prototype worked, Gemini helped refine initialization logic so voices loaded reliably behind an opening screen.
When the early version felt stable, Alex asked Gemini to generate a reusable prompt that captured the entire specification. That meta-prompt described architecture, features and constraints in detail. The file became a portable blueprint for the other models. This approach aligns with guidance from resources on effective prompts, where structuring context proves more valuable than tweaking isolated phrases.
Claude as the meticulous systems designer
Claude received Gemini’s blueprint next. It immediately improved the trigger logic behind sound and visual effects. Instead of naively reacting every time a keyword appeared, Claude decided to limit effects to once per sentence to avoid sensory overload. That decision was never requested in the prompt, but it showed a model capable of making UX trade-offs based on implied goals.
This “one trigger per sentence” rule initially puzzled Alex because only the first keyword in a long line produced an effect. After several messages, Claude finally explained the safeguard and then rewired the code to make the constraint configurable. Once refinements were stable, Claude regenerated the comprehensive prompt, now capturing both its improvements and the original intent.
Why the final prompt mattered more than the chatbot brand
When the enhanced specification reached ChatGPT, the project was already mature. ChatGPT reproduced the Tome Reader app with high fidelity, though it responded a bit slower and occasionally struggled when Alex asked for a dedicated volume slider for the background music. That missing control eventually drove Alex back to Claude, which implemented the feature and updated the prompt yet again.
The surprising discovery came during a second round of testing. Starting from the same final prompt, Alex spun up new chats with all three models. Gemini and ChatGPT both generated working versions of the app in one attempt. Claude, which had authored the most polished variant earlier, produced builds that repeatedly stalled at the initialization screen and required many retries to resolve.
Consistency, not intelligence, became the real benchmark
These discrepancies highlighted a pattern that many teams exploring AI Integration have observed. Once the prompt reached a certain level of clarity, the perceived “smartness” gap between paid and free tiers shrank dramatically. What mattered more was consistency of execution, file handling and error recovery across sessions.
For Alex, the clearest lesson was that a robust prompt turned each chatbot into a near-interchangeable engine. This echoes findings from broader industry analyses, including a study on the impact of Artificial Intelligence on chatbot technology that highlights specification quality as a key driver of outcome quality. When instructions are precise, different models tend to converge on similar Machine Learning capabilities.
Practical prompt engineering tactics learned from Tome Reader
The Tome Reader experiment offers concrete tactics you can reuse for your own AI-powered App Development projects. Treat the prompt as a living design document rather than a one-shot message. Start with the smallest functional slice of the feature, then ask the model to restate, generalize and structure that behavior before moving to the next layer of complexity.
Alex also discovered that including explicit UX guardrails in the prompt led to better behaviour than relying on the model’s assumptions. For example, describing how intrusive audio effects should be, or specifying that users must be able to toggle each enhancement, helped align the generated code with practical expectations. This mirrors best practices from resources on chatbot app development and seamless AI integration, where clarity around boundaries consistently improves reliability.
Reusable checklist for complex chatbot-driven builds
From the Tome Reader journey, Alex distilled a lightweight checklist that now guides every serious Conversation Design session with Chatbots. It focuses less on technical jargon and more on unambiguous behaviour descriptions. Teams building assistants for finance, health or productivity scenarios can adapt the same template to reduce back-and-forth with the model.
Here is the distilled list Alex keeps next to the prompt window:
- Define the single primary outcome for the feature in one sentence.
- Specify input formats, size limits and failure modes for each content type.
- Describe the ideal User Experience step by step, including edge interactions.
- State what the system must never do, even if asked by the user.
- Ask the model to restate the design in its own words before generating code.
This framework shifts focus from “make this cool” to “make this predictable”. Once that discipline is in place, the particular brand of Artificial Intelligence becomes a secondary decision.
What Tome Reader reveals about the future of AI integration
Zooming out from one experimental app, Tome Reader illustrates how AI Integration is reshaping product development cultures. Developers no longer argue solely about frameworks; they compare how well different models respect constraints, document decisions and support debugging. Articles like the CNET report on vibe coding projects or coverage of Claude-related outages that pause coding sessions show how these assistants have become everyday collaborators.
As more companies deploy internal copilots, they face trade-offs similar to Alex’s. Do you prioritise a model that generates previews quickly, like Claude’s instant HTML rendering? Do you favour a platform such as Gemini that rarely fails but requires manual file handling? Or do you optimise for ecosystem reach, as some organisations do when adopting assistants integrated into messaging, like those described in reports about AI agents entering consumer apps?
From single-purpose chatbots to orchestrated AI ecosystems
Tome Reader may be a niche reading tool, yet its architecture points towards multi-agent ecosystems. One chatbot served as an architect, another as a refiner, and the third as a reliable builder. Enterprises are starting to formalise similar patterns, combining specialised assistants for security, UX copy, regression tests or deployment.
Stories of large-scale deployments, such as Microsoft’s compilation of AI-powered customer transformations, show how orchestration now rivals raw model quality as a differentiator. In that context, Prompt Engineering becomes a cross-functional skill rather than a niche technical trick, linking product owners, designers and engineers through a shared language for specifying intelligent behaviour.
The quiet conclusion from the Tome Reader experience is simple: when your prompts read like clear product briefs, Machine Learning models from different vendors start to feel surprisingly similar. The lasting advantage comes from how well you define problems, not from which chatbot tab you keep pinned in your browser.
What is vibe coding with chatbots in app development?
Vibe coding describes building applications by conversing with AI chatbots instead of manually writing every line of code. You specify behaviours, constraints and user flows in natural language. The chatbot then generates or refactors the underlying implementation. This approach accelerates experimentation and lets you focus on product intent rather than syntax, especially for prototypes or internal tools.
How did Tome Reader use artificial intelligence to enhance user experience?
Tome Reader combined browser text-to-speech, synchronized highlighting and dynamic audio effects, all orchestrated through AI-generated code. Chatbots interpreted natural language requirements to wire up file uploads, parsing logic and trigger-based sound or visual cues. The result was an immersive reading environment where AI controlled timing and reactions while still respecting user controls, such as toggles and volume management.
Why was a well-crafted prompt more important than the choice of chatbot?
Once the prompt described the architecture, edge cases and UX expectations in sufficient detail, multiple models produced almost identical implementations. Performance differences between paid and free tiers largely disappeared. The key Success Factors were clarity, structure and completeness of the instructions, not the chatbot brand. A strong prompt essentially turned each model into a compatible engine behind the same specification.

Yes, motivated non-developers can often assemble working prototypes by iteratively describing what they want, asking the model to explain its output and testing in a browser. They still need patience, basic debugging habits and a willingness to refine prompts. However, deep programming expertise is no longer a strict requirement for early experiments, especially when chatbots provide explanations alongside generated code.
How does this approach relate to broader trends in AI integration for products?
The Tome Reader case reflects a larger move toward AI copilots embedded across product teams. Organisations now view Chatbots as collaborators for specification, documentation and implementation. This aligns with industry trends where Artificial Intelligence supports design, analysis and deployment workflows in parallel. Prompt Engineering, Conversation Design and model orchestration are becoming shared competencies in modern software teams.
