What is iSpring?

AI drafting reaches the slide deck — iSpring's core authoring format is now generated, not built

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.

What is Blockly?

Accessibility moved from plugin to core, and v13 is now being hardened around that default.

Blockly shipped v13.0.0 in mid-June: keyboard navigation and screenreader support are on by default, and the separate keyboard-navigation plugin is folded into core and meant to be uninstalled. The two point releases since have been consolidation — a FOCUSABLE capability on IComponent, paste-near-focus, more navigation shortcuts, and a long tail of ARIA-label fixes. The v13 line arrived through nine betas, several of them carrying breaking changes that forced custom blocks and fields to declare their own roles and labels.

AI drafting reaches the slide deck — iSpring's core authoring format is now generated, not built

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

5.0

Accessibility moved from plugin to core, and v13 is now being hardened around that default.

◆ Current state

Blockly shipped v13.0.0 in mid-June: keyboard navigation and screenreader support are on by default, and the separate keyboard-navigation plugin is folded into core and meant to be uninstalled. The two point releases since have been consolidation — a FOCUSABLE capability on IComponent, paste-near-focus, more navigation shortcuts, and a long tail of ARIA-label fixes. The v13 line arrived through nine betas, several of them carrying breaking changes that forced custom blocks and fields to declare their own roles and labels.

◆ Where it's heading

The work is shifting from making accessibility correct to making it fast and localizable. v13.2.0 rewrites insertion markers for performance and memory-leak reasons, exposes setAriaTypeName on fields, and allows translated field labels — the first release in this window where the accessibility surface is being tuned rather than built. Invalid-input handling that no longer relies on color alone points the same direction: the a11y pass is now reaching the visual layer, not just the ARIA tree.

◆ Prediction

Expect continued 13.x point releases in the same shape — ARIA and focus-behavior fixes plus targeted performance work on drag and rendering paths, with translation coverage extending to more built-in block strings.
