5-Voice Socratic Spoken Lessons

Active audio learning designed around cognitive inflection points. Unlike passive podcasts, Socratic audio features an inquiring student voice who asks the exact clarifying questions you are thinking, paired with an Interactive Checkpoint Auto-Pause that locks audio until you make a prediction.

Voice Casting Lab: Audition Dual-Voice Pairings

Listen to four distinct pairings running identical Socratic dialogue clips synthesized with Pocket-TTS.

⬇ Download Lab (.html)
Pair A: Classic Mentor & Student
Caro Davy (Academic) & Michael (Curious)

Refined British documentary delivery providing commanding clarity, paired with Michael's analytical student queries.

Pair B: Peer Discussion
Anna (Supportive Teacher) & Eve (Inquirer)

Empathetic, clear pedagogy. Eve actively challenges nuances in definitions and catches subtle edge cases.

Pair C: Authoritative Broadcast
Peter Yearsley (Curator) & Michael

Deep, resonant baritone delivery evoking documentary clarity, balanced by Michael's brisk student questions.

Pair D: Oxford Tutorial
Charles (Professor) & George (Reflective)

Warm, seasoned tutorial dialogue. Charles provides historical context while George connects practical analogies.

The Altheia Desktop Engine

A private, local-first desktop application built with Tauri, Rust, Node/Express, and React. Your materials stay on your machine. The local SQLite vault is fully navigable without internet access.

Client Architecture Node + Express Sidecar

Smart Multi-Format Ingest

Point Altheia at a messy folder of lecture PDFs, slides, and scanned notes. The engine hashes, deduplicates, extracts text layers using PDF.js, and runs OCR on screenshots, automatically filing files by course and topic.

Deterministic Logic FSRS-5 Algorithm

FSRS-5 Spaced Repetition Drill Loop

The machine never hallucinates review dates. Spaced repetition intervals are computed strictly by FSRS-5 formulas. You grade your own answers (Again / Hard / Good / Easy) so a wrong machine grade never corrupts your memory model.

Invariant Principle Ground-Truth Attributions

Mandatory Provenance Badging

Every generated explanation or quiz item carries a provenance badge: Syllabus (quoted directly), Derived (synthesized by logic), or Guess. You always know whether a concept comes from your professor's lecture or the model.
