Roadmap

V1: The Prototype

The initial version only contains the core concept of being able to generate individual training plans based on user input (text/form).

• Generate TP based on user input (free form and configuration menu)
  • Frontend displays simple one page app with text box and advanced settings
  • Backend provides endpoint for retrieval-augmented generation
  • Database contains training plans scraped from the web (tiny scope) and their embeddings
• TP are exportable/printable as PDF
  • Frontend includes Button for exporting PDF
  • Backend allows the user to get PDF exports of Trainingplan data
• Requests are anonym and no user identification is necessary
  • Authentication is omitted for v1
  • Any user information is stored encrypted if not configured otherwise
  • Frontend displays the option to not upload results in advanced settings
• Backend allows user to upload training plans
  • Backend-only implementation of training plan donation
  • Backend-only implementation of feedback

V2: User-specific TPs and TP History and Multimodal Generation

The next version takes lessons learned in v1 into consideration and adds user authentication and generation history, making the web application a lot more useful.

• Add chat interaction for logged-in users for adaptation of results
  • Builds upon the content of v1 by adding chat-like interaction
  • Chat interaction is integrated as part of the go backend
  • Chat history and user data saved in DB
• TP can be recommended/donated
