v2.0.5
February 25, 202615 slash commands, spectral adaptive difficulty, memory-grounded quizzes, and a rebuilt notes experience.
Slash Commands: 15 Commands for Active Learning
A command system built directly into the chat. Type / and an autocomplete menu appears with keyboard navigation, grouped by learning strategy.
Surfaces concepts at risk of forgetting (below 50% retrievability) and generates a targeted quiz
Predicts what you'll forget in the next 48 hours using forgetting curve projections
Tracks your daily review streak with persistence across sessions
Shows your lowest-mastery topics ranked by weakness
Full cognitive profile dashboard: working memory, processing speed, attention span, mastery stats
Generates a quiz calibrated to your zone of proximal development using spectral difficulty analysis
Rapid-fire low-stakes quiz, 1–20 questions
Free recall exercise: write everything you remember, then see what you missed
Elaborative interrogation: the AI asks you deep 'why' questions to strengthen understanding
Feynman technique: explain a concept to the AI acting as a curious student (5 exchange limit)
Finds the shortest path between two concepts in your knowledge graph
Visualizes your knowledge graph neighborhood, color-coded by mastery
Generates a learning pathway, prioritizing prerequisites and weak areas
Pomodoro timer with break duration calibrated to your attention span profile
Lists all available commands
Smart Quiz Scheduling & Pre‑Generation
Schedule quizzes for later — 30 minutes, 1 hour, end of day, tomorrow morning, or a custom time.
The system pre-generates quizzes 5 minutes before they're due, so when the notification pops up the quiz loads instantly. A poll runs every 60 seconds checking the queue.
Spectral Adaptive Difficulty
Quiz difficulty is no longer generic. The system uses eigenvalue gap analysis on your knowledge graph's node stability distribution to compute the right challenge level.
- Spectral gap analysis determines if your knowledge is stable (easier questions) or volatile (harder questions)
- Domain-adaptive calibration detects your primary domain (math, programming, language, science) and adjusts question style
- Cognitive profile blending: 70% spectral recommendation + 30% digital twin data (attention span, processing speed)
- Question count adjusts based on your attention span profile
Memory‑Grounded Quizzes
The backend quiz endpoint now searches your mem0 memories before generating questions. It pulls up to 8 relevant memories for the topic and grounds the quiz entirely in what you've actually studied — no invented facts.
Rich Markdown Rendering
Chat responses and quizzes now render with full markdown support via remark-gfm + rehype-katex.
- LaTeX math: inline $E = mc² and display ∫₀∞ e^{-x²} dx
- Syntax-highlighted code blocks
- GitHub Flavored Markdown: tables, strikethrough, task lists
- Links open externally via system browser
Command Autocomplete
The autocomplete is designed to feel native:
- Appears the moment you type /
- Keyboard navigation: arrow keys to browse, Tab/Enter to select, Escape to dismiss
- Commands grouped by learning strategy with icons and AI badges
- Command history (30-item buffer) accessible via arrow keys on empty input
- Keyboard shortcuts: Ctrl+R for /review, Ctrl+Shift+T for /test
Improved Notes & Document Integration
Notes view rebuilt with support for multiple document sources:
- Drag-and-drop file imports
- Notion integration with token-based connection
- Quick paste for markdown snippets
- Per-document concept and relation extraction counts
- Search across all synced documents
Redesigned Onboarding
New guided tour system that walks first-time users through the interface step by step, with progress tracked in a persistent store.
