A web application for generating, recommeding and sharing training plans for swimmers, triathletes and trainers.
The web application is hosted in Google Cloud. The following components are involved:
- Identity-Aware Proxy (IAP) to authenticate and identify users
- Single-Page Frontend hosted in Cloud Run implemented in React
- Backend hosted in Cloud Run implemented in Go and Langchaingo
- PostgreSQL database (managed) with pgvector

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 or 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 donate results in advanced settings
- Backend allows user to donate training plans
- Backend-only implementation of training plan donation
- Backend-only implementation of feedback
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.
- Generate TP based on user input (free form, configuration) and enable the user to give feedback to adapt results
- Builds upon the content of v1 by adding chat history in backend
- TP are exportable as PDF, excel or odt
- TP can be recommended/donated
- Form added to frontend to input/donate your favorite training plans
- URL input to report new scraping targets (after allowListing and configuration)
- Request user feedback to plan after new login after previously exporting TP
- Endpoint in backend for saving feedback
- Notation/Abbreviations of different sources can be processed correctly
- User authentication and identification
- Identity-Aware Proxy for user identification and user data persistence (TPs)
- TP History can be viewed
- TPs are saved associated with user ID (JWT)
- Frontend is extended with
Historypage to view previously created TPs
- TP can be shared via URL
- Enable deletion of user data
- Add url to soft-delete all user data at the bottom of the page
- User data is retrievable or 30 days, then fully deleted
- Add content required by german/eu law
- Impressum
- Generate TP based on multimodal user input (pdf, image, hand-written notes)
- The third version further builds upon v1 and v2 by adding more input options for generating or donating TPs
- Searchable Community Board for most popular TP
- A searchable community forum of previously created and liked TPs.
- This also allows user interaction, such as comments, likes and tagging.
- Optional sign-up for a leaderboard of most active users
- Add anonymous/guest mode
- An anonymous mode is added which enables new users to test the application in a similar way to how v1 works.
- Add usage statistics dashboard for each signed-in user
- KM swam in plans
- Number of plans exported
- Number of plans donated
- Comparative statistics with other user behaviour
