What it does

Octo is an all in one trip planner and navigation tool that connects to third-party services to help users get detailed information such as Routes, Estimated Trip Fare, Weather Forecast, Incident Report, Safety Score Rating of their desired location with the help of wit.ai. The third-party services include Wit.ai, Google Direction API, Google Geocode API, Here.com Traffic API, and so on. Octo supports multiple countries supported by the integrated third party services. Octo uses web speech API to collect audio from users and converts it to text. Users can also type in the message as text. The text is then sent to wit.ai for Natural language processing. Users can filter results based on several criteria to fetch relevant information.

How we built it

Tools Used:

  1. Frontend UI: Vue JS, SCSS
  2. Backend: Sails JS
  3. Database: Redis
  4. Natural Language Processing: Wit AI, Dialogflow
  5. External APIs: Here.com Traffic API, Google Direction API, Amadeus API, Open Weather API.

Challenges we ran into

We started a bit late which made it impossible to integrate Uber, Lyft, and other ride-hailing APIs. We hope to integrate them in the future.

What's next for Octo

  1. Integrate Uber, Lyft, and other ride-hailing APIs
  2. Introduce user authentication to provide a more personified experience for users
