##Inspiration## We live in a fast-paced world where people constantly doubt their choices and struggle with self-confidence. What if you could pause and talk to your future self for guidance, hope, and reassurance?

Time Travel Journal was born from that thought — to turn career anxiety, emotional struggles, and self-doubt into a unique and deeply personal experience using AI video + voice.

What We Learned

How to integrate Tavus for generating AI-powered video avatars

How to generate realistic voice responses with ElevenLabs

Using Supabase as a powerful, lightweight backend

Managing AI workflows in a low-code environment with Bolt.new

The power of emotion + creativity in tech projects

##How We Built It## We used Bolt.new to scaffold a full-stack app. Then we integrated:

Tavus to create AI video messages from your "future self"

ElevenLabs for voice synthesis of those replies

Supabase to store user Q&A history

Netlify for fast and free deployment

Entri + IONOS to host on a custom domain

Bonus: We explored Algorand to mint uplifting messages as NFTs

All this within a sleek, minimalistic UI — optimized for mobile and emotional impact.

Challenges

Creating lifelike video + voice responses in sync

Managing async workflows from multiple APIs

Fine-tuning the prompts to generate empathetic and future-oriented replies

Staying creative while working under the time pressure of a hackathon!
