Caffeine AI has opened submissions for its “You Chat, AI Builds” Promptathon, inviting developers and creators to submit working applications built using the platform over a short submission window running from February 2 through to February 4, closing at 11.59pm EST.
The structure is intentionally tight. Each participant is allowed to submit one app for review, and entries must be complete and functional at the time they are assessed. There is no scope for revisions after submission, placing the focus squarely on execution rather than concept alone.
Submissions are being handled through a Typeform designed to keep the process simple and accessible. The emphasis appears to be on lowering administrative friction so builders can spend their time refining what they are actually shipping. Caffeine has positioned the promptathon as a practical exercise, encouraging participants to demonstrate how conversational prompts translate into usable software.
Winners will be announced on February 11, 2026, giving judges a clear review window to assess entries. While Caffeine has not framed the event around hype-driven metrics, the requirement for completed apps suggests evaluation will centre on functionality, coherence and how effectively ideas have been carried through to a finished product.
For participants nearing the final stages of their builds, Caffeine is also offering additional credits to support last-minute refinements. This option may help teams or solo builders address usability gaps or polish workflows before locking in their submission.
The promptathon is open to a broad audience, from hobbyists testing small concepts to professional developers exploring more complex builds. By creating a level playing field, the event allows for diverse approaches, and organisers have emphasised that creativity, clarity and usability will matter as much as technical sophistication.
Caffeine has also shared guidance encouraging participants to focus on practical applications that can demonstrate the platform’s capabilities. Builders can experiment within the system’s new modes, whether Instant, Thinking or Pro, offering different approaches to how AI interprets prompts and produces outputs. This flexibility may allow entrants to tailor their submissions to their workflow preferences while still adhering to the competition’s completion requirements.
Prompt-based build competitions have become more common as AI tools mature, though their value often depends on how well they reward real usage rather than speculative demos. By limiting submissions and setting firm criteria, Caffeine appears to be steering the event towards depth and clarity over volume. The short timeline is also likely to test participants’ ability to work efficiently and prioritise functionality over polish, a practical reflection of real-world software development pressures.
Further details, including full instructions and eligibility, are available through Caffeine’s promptathon page. For builders already experimenting with chat-driven development, the event offers a defined opportunity to test ideas in a live setting and see how they stand up under review. The promptathon also provides an incentive to explore the platform’s capabilities more fully, as additional credits are available for users looking to fine-tune their submissions before the deadline.
