Help & Instructions — Fourier Study

A complete guide to getting the most from Fourier Study. Covers study mode, research mode, document analysis, and all major features.

Study Mode

AI Study Buddy

Ask questions about any topic and receive Socratic feedback tailored to your academic level (GCSE through Postgraduate). Fourier explains concepts using verified sources — never guesswork.

Written Tests & Active Recall

Generate practice tests from your study materials or any topic. Active recall quick-checks help you retain information through spaced repetition. Get detailed Socratic feedback without being given the answer outright.

Flashcard Generator

Turn any topic or uploaded document into a set of interactive flashcards. Review them in the Flashcards section for efficient memorisation and spaced repetition.

Revision Timetables

Generate personalised study schedules based on your subjects and exam dates. Export directly to your calendar via iCal (.ics) for Google Calendar, Apple Calendar, or Outlook.

Document Upload & Analysis

Upload PDFs, Word documents, and spreadsheets. Fourier indexes your documents using hybrid retrieval (vector + keyword search fused via Reciprocal Rank Fusion) so every answer draws on your materials.

Research Mode

Evidence-First Chat

Every research answer is grounded in verified sources retrieved via hybrid search (RRF). Citations are shown inline so you can trace every claim to its origin.

Deep Research Reports

Generate comprehensive multi-section research reports on any topic. Reports include cross-verified claims, source grading by authority, and gap reporting where evidence is insufficient.

Brief Me Mode

Get concise executive summaries on any topic, suitable for quick decision-making. Export as PDF or share as an interactive web link.

Audio Summaries

Convert research into professional audio briefings. Listen to your research on the go. Generated audio is stored in your account for later playback.

Sharing & Exporting

Share any research output via a public web link or export as PDF, PowerPoint, Word document, or audio file. Collaborative sharing lets you send outputs directly by email.

Account & Settings

Manage your study level, notification preferences, Google Workspace integration, subscription, and two-factor authentication from your account settings page.
