I downloaded AI Fiesta expecting a revolutionary all in one AI tool, especially with the hype around accessing top models like GPT 5, Claude, Gemini, and others in a single interface. Unfortunately, it falls far short. At its core, this app serves as a simple aggregator, a wrapper that routes your prompts to existing third party AI providers via their APIs. Many of these models, or similar free tiers, remain accessible directly for free or at lower costs through official platforms like ChatGPT, Grok, or Gemini. You end up paying a premium subscription for convenience that developers overstate, while facing restrictive limits and questionable practices.One of the biggest red flags comes from the token limit: capped at around 3 million tokens per month (recent updates mention increases, but it started lower and still shares across all models). For anyone using AI extensively, whether for research, writing, coding, or creative tasks, this burns out quickly. A few long conversations or complex queries, and you face throttling or must wait for the next cycle. This renders it completely unsuitable for power users, software developers, or professionals who rely on unlimited or high volume access. Developers, in particular, will find it frustrating, as it lacks the depth, customization, and reliability needed for serious coding workflows compared to dedicated tools.Even more concerning are the claims about model versions. The app advertises access to cutting edge models like "GPT 5," but widespread user reports and discussions (including screenshots shared online) suggest that responses actually come from older or downgraded versions, with the app merely labeling them as newer ones through system prompts. This feels deceptive. If you pay for premium access to the latest advancements, you expect authenticity, not relabeled outputs from cheaper APIs. Trust erodes when the app fails to verify or prove transparently that it uses the exact models advertised.The most alarming issue involves data privacy. According to their own policy, AI Fiesta collects far more information than necessary for a simple AI chat aggregator. This includes your full prompts (every question you ask), the AI generated responses, usage patterns (tokens consumed), account details (name, email, billing), payment info, and technical data (IP address, device info, browser type). They explicitly state they share this with third party AI providers to process your requests, which seems somewhat expected, but also with payment processors and other service providers for "maintaining the platform."The real danger lies in what this means for you as a user: every prompt you submit, no matter how personal, sensitive, or confidential (health advice, financial planning, private thoughts, business ideas, or even intimate questions), gets stored and potentially becomes accessible by the app developers. The policy admits they retain this data "as long as necessary" for services or legal reasons, with no strict deletion timeline for usage logs. While they claim encryption and access controls, they openly note that "no system is 100% secure." For an app that just proxies queries to other AIs, minimal justification exists for hoarding your full conversation history and prompts. Official providers like OpenAI or Anthropic often offer better privacy controls, anonymized processing, or opt outs.If you input anything private, the developers (or anyone with access) could theoretically view, analyze, or even misuse it. In an era of increasing data breaches and AI ethics concerns, this level of collection opens huge risks: potential leaks, internal misuse for "improving features," or compliance handovers. It proves especially risky for users discussing sensitive topics, as no guarantee exists of true end to end privacy. Many free or direct AI tools handle prompts more ephemerally without storing everything indefinitely.Overall, AI Fiesta feels like an overpriced middleman with restrictive limits, questionable model authenticity, and invasive data practices that prioritize collection over user protection. I strongly advise against it. Stick to official apps or free alternatives for better value, transparency, and safety. Beware before subscribing; your data and money could face unnecessary risk. 1 star.
