Inspiration

Real life doesn’t come as tasks or calendar events.

Things appear as messages, voice notes, emails, and half-formed thoughts. A real assistant doesn’t ask you to structure them — it remembers and decides when to interrupt.

Lily was built to bridge this gap.

What it does

Lily is an AI reminder assistant that works like a real personal assistant.

Users simply tell Lily things — in text, voice, or documents. Lily does three things:

Remember → Decide → Remind

Multimodal understanding allows Lily to operate in unstructured, real-world contexts instead of predefined task formats.

How we built it

Lily follows a judgment-first assistant loop:

1. Multimodal intake
   Text, voice, emails, documents

2. Intent & context extraction
   Task vs context, urgency, dependencies

3. Decision-based reminders
   When to interrupt — not fixed schedules

Challenges we ran into

• Avoiding over-reminding
• Interpreting vague instructions (“later”, “when ready”)
• Knowing when not to act

The hardest problem was restraint, not capability.

Accomplishments that we're proud of

• No calendars or task lists required
• Natural, multimodal instruction by default
• Users can hand things off instead of managing them

What we learned

Multimodal AI isn’t about more input. It’s about less user effort.

A good assistant interrupts less, but better.

What's next for Lily

Reminders are only the foundation.

Lily is evolving from awareness → action.

From reminders to actions

Many tasks are network-executable:

• follow-ups
• form submissions
• document updates
• workflow triggers

Lily detects which tasks can be safely executed and acts when conditions are met.

Action layer

• Action eligibility detection
  Human-required vs AI-executable

• Trigger-based execution
  Replies, updates, dependencies — not schedules

• Tool-based actions
  API-driven, permissioned, auditable

• Human-in-the-loop fallback
  High confidence → act
  Low confidence → remind

Vision

Lily isn’t another reminder app.

It’s an agent-ready life assistant.

Eventually, Lily won’t remind you something needs to be done.

It will already be done.
