Codex Slides: open-source AI studio turns prompts into decks in 4–5 minutes

Codex Slides addresses a core friction point in AI-assisted design: the black-box problem. Traditional one-shot slide generators (like Gamma or Tome) accept a request, hide the work, and return a finished file—forcing users to discover problems only after export and restart the entire process if the output misses the mark. Codex Slides inverts this by treating the presentation as a durable, on-disk project that remains visible and steerable throughout the workflow.

The tool's architecture keeps every step transparent. Users describe a deck, optionally attach source files or code, review and edit the outline, choose from 73 community visual styles (or 45 curated templates), watch slides render progressively in the browser, and make mark-based edits before export. All state persists to disk, so the same project stays synchronized whether accessed from the Codex browser or another tool, and interrupted work can resume safely. This approach trades the speed of a single-request generator for control and clarity—a significant shift for teams that need to iterate or preserve brand consistency.

Codex Slides runs on the user's existing Codex login and keeps projects locally, eliminating the need for separate API keys or cloud dependencies. The breadth of shipped templates (45 across 15 categories) and community styles (73 across 12 groups) plus 24 guided scenarios suggests the tool is designed to cover common use cases—from startup pitch decks and market reports to editorial layouts and data dashboards—without requiring deep design skill. The emphasis on "agent-native" positioning and the inclusion of CLI and MCP (Model Context Protocol) support signals an intent to integrate tightly into developer and coding-agent workflows rather than stand alone as a traditional app.
