agentpng

agentpng is a free, browser-based tool that transforms AI coding agent session transcripts into beautiful, shareable PNG images. It supports transcripts from Claude Code, Kiro, Cursor, Codex, Gemini CLI, Copilot CLI, and ChatGPT, with auto-detection of file formats. Everything runs entirely in the browser — no data is uploaded to any server, ensuring complete privacy. Users can paste or drag-and-drop session files and export styled screenshot cards in seconds.

• Multi-agent support: Parses transcripts from Claude Code (.jsonl), Kiro (.md), Cursor (.md), Codex (.jsonl), Gemini CLI, Copilot CLI, and ChatGPT (.json) with auto-detection.
• Customizable themes: Choose from multiple syntax highlighting themes (e.g., Vitesse Dark, GitHub Light, Nord) with your selection saved across sessions.
• Flexible display options: Toggle tool calls, timestamps, reasoning/thinking blocks, plans/tasks, sources, and macOS-style window buttons on or off.
• Message selector: Check or uncheck individual messages to include only the most relevant parts of a conversation in the exported image.
• Split export: Split the card into multiple segments by message, content boundary, or manual click-to-split — ideal for platforms with image size limits.
• Platform size presets: Quickly set card dimensions for Twitter/X (600px), Threads (540px), LinkedIn (700px), Instagram (540px), TikTok (450px), or a custom width (400–900px).
• Agent skill integration: Install the agent-transcript skill via npx skills add siegerts/agent-transcript to let your coding agent find and export session transcripts directly.
• Fully client-side: No account required, no data uploaded — parse and render sessions entirely in your browser for complete privacy.
• Generic format support: For unsupported agents, paste plain text with User: and Assistant: prefixes to use the generic parser.
