Changelog

v1.1.0 — on npm, in English and with backups

• One-command install: npx estudar downloads and starts the app and the Server & keys screen, without cloning the repository. Keys are stored in ~/.estudar (or the folder given in ESTUDAR_HOME). Options --port, --no-open, --help and --version.
• The app in English and Portuguese: all interface text, server messages and AI-generated plans follow the language chosen in Account → Language, detected automatically from the browser.
• Bilingual documentation (Portuguese and English), with screenshots in both languages.
• A Buy Me a Coffee support link in the docs and the README.
• Backup: export all your data to a JSON file and import it, merging with what is already there (without duplicating logs). The file is validated and invalid rows are discarded.
• The Account sheet now scrolls on small screens.

v1.0.0 — first public release

Learning

• Unaided mastery: only closed-book tests on paper, with no notes, days later; practice with help and unaided kept apart; a relies-on-help warning.
• Block log in the right order: attempts, confidence (1–4) and help used before marking; number correct afterwards. Optional self-explanation.
• Calibration: overconfidence detected per subject and put at the top of Progress.
• Exam dates per subject: the day before is review only, with priority in the final week.
• Time allocation by ECTS × deficit, with a 10% floor, sent to the AI.

Degree record

• Modules by year and semester, with photo import of the curriculum.
• ECTS-weighted average, truncated the way university academic offices do it; the grade needed not to lower your average and to reach a target.
• Assessments with weights and minimum grades; regular exam period, resit and special period; final grade calculated and rounded.
• Prerequisites with a weak foundation → more time and a review of the basics.
• Year → semester board and a semester report with prediction vs. grade.

Plan

• A plan per user: sample, by hand or AI-generated (Gemini, Claude or OpenAI-compatible) with an evidence-based prompt.
• A fixed science check on any plan: workload, spacing, retrieval, passive techniques, languages.

Platform

• A Cloudflare Worker serves the app and the API, with the keys stored as secrets.
• npm start with a Server & keys screen: save keys, create tables, connect your Cloudflare account and publish in one click; a status panel per service.
• Supabase: sign-in with an emailed code, one document per user with RLS, real-time sync.
• Clock-based timer that survives the background and closing the app; focus mode with full screen and the screen kept on.
• Offline PWA; welcome page with the references.
• Rule tests (npm test), checked with mutations.

Before 1.0

A personal prototype with Firebase and a plan hard-coded in the source, an interface redesign and the first version of the timer. Fully replaced in 1.0.
