Memex

Memex is a Rust command-line and self-hosted tool that indexes local coding-assistant conversations for keyword, optional semantic and hybrid search, transcript browsing, supported session resumption, and local usage reporting.

Practical overview

When it fits

Use Memex when you need to retrieve prior work from locally saved coding-agent conversations, inspect its transcript, or continue a supported session in its original tool.

Who it is for

  • Developers who use coding assistants and need to find or reread earlier conversations.
  • Users of supported coding tools who want to resume an available session in its original agent.
  • Teams or individual developers who want agent histories searchable across machines over SSH.

Documented uses

  • Search indexed coding-agent conversations by topic or project.
  • Read an original transcript and resume a supported session in its source tool.
  • Search saved Claude Code and Codex memories alongside conversation history.
  • Review token usage reconstructed from local tool records.
Before you choose

Requirements & limits

  • Indexing and search depend on conversation records available locally for each source tool.
  • Resume requires the source agent to be installed and the session data to remain available.
  • Embeddings, plaintext reasoning indexing and token tracking are off by default.
  • Token-use reporting depends on source-specific local records; Copilot usage requires local OpenTelemetry export files, while Kiro reports credits rather than token counts or costs.
  • Experimental transfers reconstruct conversation content and do not migrate the complete agent runtime or workspace state.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Index and search local agent history

Create an index of available local conversations and retrieve a matching transcript.

Before you start

  • Install Memex using a documented installation method.
  • Have locally available conversation records from a supported coding tool.

Steps

  1. Run memex index to index discovered local agent history.

  2. Run memex search "deployment rollback" --format text with a search phrase relevant to the earlier work.

  3. Use memex session SESSION_ID to read a transcript page for a session.

Expected outcome

Memex indexes available history, returns matching search results and can display a selected transcript.

Guide limitations

  • History coverage depends on the records each source tool saves locally.
  • Semantic and hybrid search require optional local embeddings; keyword search uses BM25.
