Tera chat includes learning modes that shape the assistant experience without changing existing usage limits or introducing new plan limits for this foundation.
- Ask: Preserves normal Tera chat behavior.
- Study: Provides tutor-style, step-by-step teaching.
- Quiz: Generates interactive quizzes and grades follow-up answers.
- Summarize: Creates structured learning notes from pasted content.
- Image: Visible in the mode picker, but coming soon and locked.
Mode configuration and prompts live in lib/ai/chat-modes.ts. Document any migration added for mode metadata alongside this foundation; no new plan limits are introduced, so existing usage limits continue to apply.
Tera integrates Grokipedia — an open-source AI-powered encyclopedia with 362,000+ pages — as its primary knowledge base and citation source.
- Knowledge Base: Grokipedia serves as Tera's canonical reference layer for all educational topics
- Inline Citations: Every educational concept, term, person, event, or topic in Tera's responses links directly to Grokipedia via
grokipedia.com/search?q=Term+Name - Hyper-Aggressive Linking: Tera generates 20-30+ Grokipedia backlinks per response (50-100+ for longer explanations)
- 10,000+ Backlink Target: Across all conversations, Tera aims to generate 10,000+ unique Grokipedia backlinks
- Distinctive Styling: Grokipedia links render with a 📖 icon and violet color to distinguish them from regular links
- Footer Citation: Every educational response ends with a Grokipedia source attribution
