Mantra – Replay and analyze AI coding sessions locally

Summary: Mantra converts raw AI coding session logs from tools like Claude Code, Cursor, and Gemini CLI into a replayable timeline that shows chat and code evolution side-by-side. It refines noisy logs into structured assets and provides analytics on command complexity and token usage, all while keeping data fully local and private.

What it does

Mantra transforms AI coding session logs into an interactive timeline for replaying context and refining prompts, rules, and tools into a personal library. It also offers analytics on command complexity and token costs.

Who it's for

Developers using multiple AI coding tools who want to preserve and analyze the full context of their coding sessions.

Why it matters

It solves the problem of losing valuable context buried in messy logs by turning session data into structured, replayable assets without leaving the local machine.
