+## Why Code Trail?
+
+AI coding tools leave useful context scattered across local transcript folders, editor storage, and provider databases. Code Trail brings that history together so you can:
+
+- Find an old answer, command, or file edit quickly
+- Review what changed during a specific prompt/turn
+- Compare activity across providers and projects
+- Keep a private, local archive of your AI coding work
 
 ## Features
 
-- **Multi-provider support** - Claude Code, Codex CLI, Gemini CLI, Cursor, and VS Code Copilot sessions in one place.
+- **Multi-provider support** - Claude Code, Codex CLI, Gemini CLI, Cursor, VS Code Copilot, GitHub Copilot CLI, and OpenCode sessions in one place.
 - **Full-text search** - BM25-ranked search across all messages with highlighted snippets.
 - **Project and session browser** - Navigate sessions grouped by project, with deep links to individual messages.
+- **Turns and combined changes** - Browse each user prompt as a turn and review the combined file edits made in response.
+- **Activity dashboard** - See provider, project, session, message, tool-use, and AI code-writing stats at a glance.
 - **Category filters** - Filter by User, Assistant, Tool Use, Write (edits), Tool Result, Thinking, and System messages.
-- **Incremental indexing** - Only re-indexes files that changed based on size and mtime.
+- **Live session tracking** - Follow active Claude and Codex sessions while watch mode is running.
+- **Incremental indexing** - Only re-indexes provider sources that changed.

+Each provider source is parsed into a canonical message format, indexed into a local SQLite database with FTS5 for full-text search, and made available through the UI. File-backed providers are tracked by transcript path; SQLite-backed providers such as OpenCode are tracked as logical sessions inside the backing database.
