Echoes

Inspiration

We often forget to say what matters most — until it's too late. Echoes lets anyone record a message, write a memory, or generate an AI-powered video or voice capsule, and schedule it to be delivered in the future — on a birthday, wedding, graduation, or just when someone needs it most.

What if you could hear your loved one’s voice 20 years later? Or tell your child something before they’re born? Echoes makes that deeply human experience possible — with the power of AI and beautiful design.

What It Does

Echoes is a single-prompt Bolt.new app that lets users:

Record text, voice (via ElevenLabs), or AI video (via Tavus)

Choose a future delivery time (date or life milestone)

Store and organize capsules in a secure, animated vault

Deliver capsules via email, SMS, or embeddable link

Everything is beautifully animated and emotionally immersive — with AI helping users craft their legacy, voice it, and visualize it.

How We Built It

We used only one AI prompt in Bolt.new to build the entire production-ready app. It includes:

A hero landing page with full-screen animations

Animated capsule creation wizard (multi-step UI)

Integration logic for ElevenLabs + Tavus (simulated for demo)

Capsule preview with voice/video player

Future delivery scheduler with calendar & countdown logic

Glowing “vault” design for user’s time capsule library

Fully responsive design with Tailwind & custom animation logic

Deployable via Netlify with a custom IONOS domain via Entri

Paywall integration mock using RevenueCat (optional premium features)

Challenges We Ran Into

Fitting the full functionality into a single Bolt.new prompt was tough — we had to design for flexibility and visual wow-factor while still delivering real AI-powered value.

Tavus has no direct frontend integration yet, so we simulate it with placeholders and hooks to showcase how it would embed in the final experience.

Creating emotional resonance in a short timeframe was a challenge — but the result is powerful and intuitive.

Accomplishments We’re Proud Of

Built a complete product with a single prompt

Integrated real AI voice and video agents as the core feature

Created an app that can scale emotionally, technically, and virally

Beautiful design and deep functionality in one click

Aligned with multiple hackathon prize tracks

What We Learned

Emotion + AI + great design = unmatched user connection

With the right idea, 1 prompt in Bolt is enough to build something magical

ElevenLabs + Tavus aren’t just features — they’re transformative mediums when embedded in the output

People care about legacy, memory, and love — AI just helps express it

What’s Next for Echoes

Turn simulated ElevenLabs + Tavus outputs into real dynamic integrations

Let users sell time capsule templates (e.g., Wedding Package, Baby Message, Legacy Letter)

Add Supabase auth + storage for secure private capsules

Add blockchain (Algorand) for encrypted or token-gated capsule access

Integrate Tavus hooks as product features (e.g., recurring AI mentor messages)

Launch on Product Hunt, TikTok, and Reddit (viral-worthy)
