  • This app hasn’t received enough ratings or reviews to display an overview.

What's new in version 1.2: • Import almost anything: Word (.doc/.docx), classic PowerPoint (.ppt), Excel, OpenDocument, RTF, EPUB, and CSV files now convert to decks entirely on your Mac — no upload, no account, powered by a bundled offline converter. • Now available in 12 languages — Lectern AI is fully localized into Arabic, Simplified & Traditional Chinese, Dutch, French, German, Italian, Japanese, Korean, Brazilian Portuguese, Russian, and Spanish. • Sharper diagram understanding (Pro): visual slide analysis now locates each chart or diagram on the slide and reads a full-resolution close-up, so labels and values make it into your talk track. • Vision sidecar (Pro): if your selected AI model can't see images, Lectern automatically borrows a vision-capable model from another provider you've configured — fastest writer and sharpest eyes, in the same run. • Scanned-PDF OCR (optional): image-only PDFs can be recovered via Firecrawl Parse with your own key — always behind an explicit disclosure before anything is uploaded. • Faster visual analysis: image-heavy slides are now read in parallel, and a live status banner shows exactly which AI engine is reading and which is writing. • Current-generation AI models across every provider, with honest benchmark-backed defaults. • Stronger privacy & security: hardened how local and custom AI providers connect (endpoint validation and redirect protection), and your API keys are no longer kept in plain text at rest. • Reliability and polish fixes throughout. Thank you for using Lectern AI! Questions or feedback are always welcome at remnantsecurity.com.
