What they are
Gamma
Gamma is an AI presentation and content platform that turns a prompt, outline, or pasted document into a presentation, webpage, or document using a fluid card-based format rather than fixed slides. It targets marketers, educators, consultants, and small business owners who need polished visual content without a designer. Outputs publish directly as web pages or export to PowerPoint, PDF, and Google Slides. The free tier is genuinely usable for testing, but its 400 non-refilling credits mean most regular users will need a paid plan.
Sonix
Sonix is an automated transcription service that converts audio and video files into text using AI, then lets you search, edit, and export transcripts in multiple formats. Journalists, podcasters, researchers, and video producers use it to speed up post-production workflows. Transcription accuracy is solid for clear audio but drops noticeably with heavy accents or poor recording conditions. There is no free tier, so you pay from the first minute.
