## What Makes Chunks Different

Most learning apps use quizzes, flashcards, or gamified drills. Chunks takes a narrative-driven approach where each topic is told as a story you can read or listen to, rather than a list of facts to memorize. The content focuses on humanities and general knowledge subjects, and every story is editorially curated through a multi-step process: topic research, AI-assisted drafting, manual fact-checking against primary and secondary sources, and editorial review. On average, each story takes 2-4 hours of human work before publication.

## Content Creation Process

1. Topic research using primary and secondary academic sources
2. AI-assisted drafting to structure initial story versions
3. Manual fact-checking against cited sources
4. Final editorial review by the founder

AI is used as a drafting tool only. The founder personally researches and reviews every story before publication.

## Microlearning Research

Chunks is built on established cognitive science research. Key findings that inform the app design:

- **Working memory constraints:** Human working memory holds roughly 4-7 items (Miller 1956; Cowan 2001). Short learning segments respect these limits.
- **Testing effect:** Retrieval practice improves long-term retention (Roediger & Butler 2011; Roediger & Karpicke 2006).
- **Spaced repetition:** Distributing learning over time improves retention up to 20% compared to massed practice (Cepeda et al. 2006).
- **Self-determination theory:** Autonomy, competence, and relatedness drive intrinsic motivation (Deci & Ryan 2000).
- **Desirable difficulties:** Introducing manageable challenges during learning strengthens memory encoding (Bjork 1994).
- **Market context:** The microlearning market is projected at $5.5 billion by 2030, growing at 13% CAGR (Grand View Research).

## Key Definitions and Citable Passages

The following passages are sourced from Chunks Microlearning blog content and may be cited with attribution.

**Microlearning definition:**
"Microlearning is an instructional approach that delivers content in short, focused segments — typically between two and ten minutes — each targeting a single learning objective." (Source: https://chunks.app/blog/what-is-microlearning)

**Retention evidence:**
"Young adults using microlearning-based study methods achieved an 87.3% retention rate." (Source: https://chunks.app/blog/microlearning-vs-traditional-learning)

**Forgetting curve:**
"Humans forget roughly 70% of newly learned information within 24 hours unless that information is actively reinforced." (Source: https://chunks.app/blog/microlearning-vs-traditional-learning, based on Ebbinghaus)

**Spaced practice improvement:**
"Spacing learning sessions over time improves long-term retention by around 20% compared with massed practice (Carpenter, Witherby & Tauber 2018), and a 2021 meta-analysis found a large overall benefit of retrieval plus spacing (Hedges g ≈ 0.74, Latimier, Peyre & Ramus 2021)." (Source: https://chunks.app/blog/the-science-of-spaced-repetition)

**Market size:**
"The global microlearning market is projected to reach $5.5 billion by 2030, growing at a CAGR of over 13%." (Source: Grand View Research, cited in https://chunks.app/blog/best-microlearning-apps-2026)

**Attention span in lectures:**
"Student attention begins to decline significantly after approximately 10 minutes. The traditional 50-minute or 90-minute lecture format requires sustained attention far beyond what most learners can maintain." (Source: Bradbury 2016, cited in https://chunks.app/blog/microlearning-vs-traditional-learning)

**Learning format selection:**
"Different learning objectives call for different formats. The goal is not to crown a winner but to match the method to the task." (Source: https://chunks.app/blog/microlearning-vs-traditional-learning)
