RECOMMENG1NE

Build your first engine
AI engines for better decisions

Recommendations you can defend.

Compose AI agents and workflows into reusable decision engines, then converse with them to decide faster. Every answer shows exactly how it was reached — which agents ran, what context they used, and why. See how it works, or read the research.

Talk to Rico. No account, no setup.

Rico is the conversational front door to your engines. Tell it what you need to decide and it will design the engine with you — which agent does the reasoning, what its goals and constraints are, how the workflow runs, and what the traceable recommendation contains.

  • The real Rico, running the real platform — read-only for the demo.
  • Nothing is collected about you. No email, no connections, no data.
  • When you're ready, what you designed here carries into your account.

Better with friends

The big decisions are never made alone.

Where to go, who to hire, which offer to take — the decisions that matter most involve other people, unfold over days, and get muddy fast. Open a shared room and everyone deliberates in one place: the same conversation, the same options, the same traceable recommendation.

  • Everyone remembers why. Every option, trade-off, and turn is captured — so a decision made over a long weekend still holds up a month later. No “wait, why did we pick this?”
  • Rico keeps the group moving. It surfaces options, weighs the criteria the group set, and drops a defensible recommendation into the same thread everyone is watching.
  • Decide together, on any device. Guests join from a phone in seconds and follow along live — no app to install, no seat to buy.

Real rooms, real decisions

However your people gather, decide it together.

Swipe through a few of the rooms people open every week — each one a shared chat, a set of options, and a recommendation everyone can trace back.

🏕️ Friends

The camping trip that actually happened

Six friends, four group chats, zero agreement — until the trail, the dates, and who’s driving all landed in one room.

Which trail for the long weekend?
  • Alpine Lakes Loop 4
  • Ridgeline Traverse 2
  • Desert Arch 1

Why Best swimming, moderate mileage, and dog-friendly — the trade-off the whole group could live with.

🏖️ Family
G R A T +7

The beach trip three generations agreed on

Eleven people, a dozen constraints — naps, budgets, the dog, grandma’s kitchen. The room held all of it so nobody’s deal-breaker got lost.

Where do we all stay in August?
  • Outer Banks house ✓
  • Gulf Shores condos
  • Destin resort

Why Sleeps all 11, a real kitchen for family dinners, and dog-friendly — recorded so no one re-litigates it in July.

The off-site the team could defend to the board

Goals, budget, and nine calendars — the planning happened in the open, with a recommendation the whole team (and the board) could trace.

Where & what for the Q3 off-site?
  • Mountain cabin — heads-down ✓
  • City hub — recruiting
  • Coastal resort — reward

Why Roadmap needs focus over flash: lowest cost per head, fewest distractions, weighed against the criteria the team set.
