Numas Study: study & chemistry

Numas

About this app

Numas Study turns your lecture notes into material you can actually study: summaries, key points, glossary and multiple-choice quizzes with explanations, plus spaced repetition that brings questions back at the right time.

IMPORT EXAM QUESTION BANKS
Load the bank PDF: questions are recognised without an AI key and, if the answers are ticked, so are the answers. Unanswered questions become flashcards.

CHEMISTRY, FULLY OFFLINE
Ten tools that work without connection or key: periodic table, molar mass, concentrations and dilutions, pH and buffers, balancing, limiting reagent and yield, reaction products, functional groups with IUPAC name, organic reactions, nomenclature exercises. Accepts SMILES and condensed formulas (CH3CH2OH, CH3CH=CH2) and explains mistakes with position and fix.

STUDY PLAN
Set the exam date and hours per day: build the plan by hand from your documents, or let the AI generate it with documents assigned to days.

LAB NOTEBOOK
One notebook per experiment: measurements table, notes, report (ready structure or AI-generated), free fields, reference documents. Export to RTF (Word), Markdown and CSV.

AI IS OPTIONAL, WITH YOUR OWN KEY
AI features (document processing, tutor chat, automatic plan) use an API key you provide — Gemini's is free. Texts you process go to the provider you choose; the author receives nothing. Everything else works without it.

PRIVACY
Documents, questions and results stay on your phone. JSON backup and export, no account.

FREE AND PRO
Free: one course, five documents per course, five AI processings per day, and all of chemistry, question banks, quizzes and lab. Pro (€2.99/month or €19.99/year, 7-day trial): unlimited courses and documents, AI chat, automatic study plan, RTF report.

AI-generated content may contain errors: always check it against your course materials.
