The Challenge

Unlimits turns a user's goals, described in plain language, into a structured plan with daily micro-tasks — a coach, habit system and task engine in one app. As they scaled, three problems surfaced: almost everything the user sees is AI-generated, so quality assurance needed real structure; every interaction carried a running cost with no clear per-feature visibility; and the team couldn't see inside a user session to replay edge cases or catch issues before users did.

What We Built

Optomize rebuilt the Unlimits AI engine from the ground up — full visibility into every user interaction, a memory system that scales, a self-tuning loop that improves the experience per user, smart cost controls, and a platform built to grow. The app gets sharper the longer someone uses it, costs less to run, and is ready for the next stage.

Platform Capabilities

  • Clear visibility — Every session captured in detail — what the app did, how long it took, what it cost. When a response misses, the team sees why immediately.
  • Self-healing AI — Each response is checked against how the user actually engages. The system tunes itself per user over time — no manual retraining.
  • Long-term user memory — Holds goals, patterns and the gap between intent and action reliably over months, without runaway cost.
  • AI research engine — Researches the internet per user in real time, surfacing guides and resources matched to where they are right now.
  • Personalised notifications — Nudges timed to when each user is most likely to engage, framed around what's relevant to them.
  • Smart cost controls — System redesigned to hold quality while cutting running costs significantly — savings sustained as traffic grew.
  • Built to scale — AI behaviour ships with the same confidence as any app update, safety checks built in.

Closing Thoughts

  • Significantly lower running costs, sustained as traffic grows.
  • Improved user retention, driven by personalised, timely engagement.
  • Full visibility into cost and performance per user, resolved in real time.
  • A platform designed for years of user history without becoming fragile.
