Adding AI to an app is more than getting a model response. What the user submits, what they see while waiting and how they recover from failure are all part of the product. At Nucax, we consider these alongside the feature itself.
Define the task before selecting the model
“Add AI” is an open-ended request. “Turn a spoken entry into editable text” gives you an input and an outcome that can be evaluated. Start with one bounded function and describe where its result helps the user.
Nurena brings spoken or written dream entries into a journal experience. Its case study explains concrete product choices using real application screens.
Separate saving from processing
Making a user’s text depend on a successful remote request introduces a risk of losing work. Nurena stores a draft before analysis so an interrupted session can return to the text. Another product may need a queue or synchronisation; the right approach depends on the data and devices involved.
Design ready, sending, processing, completed, failed and cancelled states separately. Specify what a retry sends again and whether the original input remains editable. A failure message without a usable next action leaves the journey unfinished.
Know what leaves the device
Identify the fields the feature actually needs. Avoid attaching unnecessary profile information to free text. Explain which operations require a connection, when permission is requested and where records are stored. Nurena’s current data flow is described in its privacy policy; other products need a review of their own flow.
Evaluate representative inputs
Build a small evaluation set with short, long, incomplete and unexpected inputs. Review empty answers, unusable formats and excessive waits as well as successful responses. If the interface expects structured data, validate it before use.
Keep examples representative of the task. A voice transcription feature and a summarisation feature need different checks. Decide how a failed quality check affects what the user sees.
Estimate operating costs from usage
Write down assumptions for active users, requests per person, typical audio or text length, and retries. Calculate prices using current provider information when preparing the estimate. Usage limits and failure behaviour belong in that calculation, not just in a later operations document.
Our AI integration service covers task definition through recovery flows. If you are still selecting a first release, start with the MVP guide.
Assign responsibility after launch
Include ownership of service changes, incident investigation and usage costs in the mobile app maintenance plan.
