Preply vs iSpring

The AI push has now reached iSpring's core output format. AI Course Creator already turned documents, audio, and prompts into complete course drafts with tests and assessments included; the newest entry extends that to slide-based courses, producing a brief, an outline, and a first draft from a topic plus optional source material. Around it, AI translation localizes whole courses across QuizMaker, Visuals, and TalkMaster, in-app image generation removes the third-party generator step, and the classic track continues with Content Library character sets and faster GPU video conversion.

iSpring is methodically removing the blank page from every part of authoring — structure, lesson text, quizzes, images, translation, and now slides. Each release absorbs a step that previously required manual work or a separate tool, which is a bet that authoring volume and speed decide the corporate L&D market rather than polish alone. The non-AI work has narrowed to Content Library assets and performance, which reads as upkeep beside the generation features.

Narration and assessment authoring are the manual steps most exposed to the same treatment — TalkMaster and QuizMaker already receive AI translation, so generating their content outright is the natural extension, though none of these entries state it directly.
