AI Development
AI-powered web applications
An AI product is still a web application. It needs accounts, billing, permissions and support tooling, plus a few challenges of its own that ordinary apps don’t have.
Calling a model API takes a few lines of code. What takes the time is the product around it. Responses arrive slowly, so interfaces need to stream text as it’s generated. Requests can run for a long time, so they don’t always fit the usual web request cycle. Users need to be able to cancel, retry, edit and give feedback. And since you pay for every generated word, abuse and heavy use cost you real money.
Unit economics deserve attention early. If a power user can cost you more in model fees than they pay in subscription, your best customers become your biggest loss. Per-plan usage limits, credit systems, smaller models for simpler tasks and caching repeated work all help. We model those numbers before you set your prices.
Designing for a system that’s sometimes wrong
The interface needs to help people use AI output sensibly. That means showing sources, making it obvious when content has been generated, making correction easy and collecting feedback that you can use to improve. Rather than one big “ask anything” box, products usually work better when AI is applied to specific tasks with a clear result. For existing products, see AI integration.
Problems specific to AI products
Slow responses
Waiting for ten seconds in front of a blank screen feels broken unless responses stream as they generate.
Margins eaten by usage
Model costs rise with usage, and flat-rate pricing can be punishing without limits.
Long-running jobs
Agent tasks can last minutes, which calls for background processing and progress updates.
What we build
Streaming interfaces
Responsive chat and document interfaces with retry, stop and edit controls.
Usage and billing
Metering, plan limits and credits, connected to Stripe.
Background agents
Queued, resumable jobs with progress and results shown to the user.
Feedback loops
Ratings and corrections, stored and used to improve your evaluations.
Safety controls
Abuse prevention, content filtering and rate limiting.
