COEY Launches GroundSlate AI-Driven Video Editor Without Timeline
COEY, an AI-first media technology company, announced the launch of GroundSlate, a free Mac app designed to be driven by AI assistants rather than human manual editing. GroundSlate eliminates the traditional timeline, instead providing 385 local tools via the Model Context Protocol (MCP) to AI assistants like ChatGPT, Claude, Cursor, and Gemini. The app runs entirely on Apple Silicon, leveraging MLX to generate AI video, music, sound effects, and speech locally. It includes local AI analysis, indexing transcripts, scenes, people, and music maps into an open catalog. The app is available for free, targeting professionals who want to leverage AI for video editing.
Significant for AI video editing tools, but niche impact on AdTech. Introduces a new paradigm for AI-driven video editing, but not directly relevant to advertising technology.

Instagram Launches AI Video Assistant for Creators
Meta's video editing app Edits has launched a conversational AI assistant for all US creators, competing with CapCut. The assistant integrates with Instagram account data, analyzing metrics like views, engagement, shares, likes, and comments to provide personalized feedback, ideas, and trend analysis. It suggests hooks, concepts, captions, and scripts, explaining underperformance and offering new ideas without editing the video, as preferred by testers. The basic version has daily prompt limits, expandable via the Meta One subscription starting at $14.99/month. Tested since March and now rolling out, the assistant focuses on analysis and ideation, leaving creation to creators. Meanwhile, YouTube is integrating its Gemini model for proactive editing, including rearranging segments and syncing cuts to music, and testing A/B testing for intros, dynamic thumbnails, and AI comment moderation. Brett Westervelt, head of Edits, announced the launch on Threads.
