This study investigated the integration of a rule-based AI chatbot into A1-level French instruction to support vocabulary learning. Quantitative findings showed that the experimental group achieved significantly higher posttest scores than the control group, with a large effect size (r = 0.83, p <.001). Survey results indicated generally positive attitudes toward using the chatbot as a mobile learning tool, particularly in satisfaction and perceived usability. Focus group data reinforced these findings, highlighting accessibility, motivational value, and support for personalized, self-paced learning. Reported challenges included occasional technical issues and the absence of voice-based interaction. The findings suggest that pedagogically aligned, rule-based chatbots can support vocabulary acquisition and learner engagement. In pedagogical terms, brief, guided chatbot interactions may extend weekly instruction by providing individualized retrieval practice with immediate feedback in a low-anxiety environment, while visual cues can further support recognition and recall.
