Fluentish feasibility proof of concept.
This is a throwaway proof-of-concept, not a production service. It stores: a username, a bcrypt password hash, and any language corrections submitted through the connected custom GPT, in a local SQLite file.
Data is used only to test the GPT ↔ OAuth ↔ API integration and may be deleted at any time without notice. Do not enter real passwords or sensitive personal information.
