A scoping review of AI-mediated informal language learning: Mapping out the terrain and identifying future directions

Abstract This scoping review directs attention to artificial intelligence–mediated informal language learning (AI-ILL), defined as autonomous, self-directed, out-of-class second and foreign language (L2) learning practices involving AI tools. Through analysis of 65 empirical studies published up to mid-April 2025, it maps the landscape of this emerging field and identifies the key antecedents and outcomes. Findings revealed a nascent field characterized by exponential growth following ChatGPT’s release, geograph…

The quick read

This October 2025 scoping review synthesized 65 empirical studies up to mid-April 2025 on AI-mediated informal language learning, defined as self-directed out-of-class L2 learning with AI tools. It found a nascent, fast-growing field after ChatGPT's release, concentrated in East Asia and dominated by cross-sectional designs with limited theory.

The synthesis matters because it links informal AI use to measurable learner outcomes beyond formal instruction, specifically speaking gains and lower communication anxiety. Uncertainty remains about long-term effects, broader populations, and causal mechanisms given the methodological and geographic limits of the current literature.

Main points
  • Scoping review analyzed 65 empirical studies published up to mid-April 2025 on AI-mediated informal language learning.
  • Field showed exponential growth following ChatGPT's release and geographical concentration in East Asia.
  • Learner practices were influenced by cognitive, affective, and sociocontextual factors.
  • Review positions AI-ILL as evolving subfield within intelligent CALL.
Gain

Learners using AI tools for autonomous out-of-class language practice showed improved speaking proficiency and reduced communication anxiety.

The rundown

The review defined AI-ILL as autonomous, self-directed, out-of-class L2 learning with AI tools and mapped 65 studies through mid-April 2025, noting exponential growth after ChatGPT and concentration in East Asia.

It found practices shaped by cognitive, affective, and sociocontextual antecedents and reported benefits across linguistic, affective, and cognitive dimensions, with strongest signals for speaking and anxiety.
