JCal

JMail is a Gmail fork and searchable web application built around the released Epstein files. It lets users access an inbox presented as if they were Jeffrey Epstein, using structured data extracted from more than three million pages of redacted PDFs by Reducto. JMail grew into a suite of related applications, including JFlights, which turns handwritten flight logs and other difficult documents into searchable records.

JFlights is a searchable application that surfaces Jeffrey Epstein and his affiliates' flight history from handwritten flight logs. It uses Reducto's document-processing pipeline to parse difficult PDFs and extract structured flight records through a configured schema, with extraction results inspected before the data is exposed through an application interface.

jcode is an open-source, Rust-based terminal harness for AI coding agents and LLM workflows, designed for interactive development across multiple sessions. It supports resumable sessions, session search, multi-agent swarm and helper-agent workflows, compatible model-provider integrations, MCP, browser automation, and a self-development mode; installation scripts target macOS, Linux, and Windows. For automatic memory, jcode embeds turns and responses as semantic vectors, searches a graph of stored memories using cosine similarity, and feeds relevant results into the conversation. A memory sideagent can verify and expand retrieval, while periodic extraction stores new memories and ambient consolidation reorganizes entries and checks for staleness and conflicts. Explicit memory tools and traditional retrieval over previous sessions are also available. Its terminal UI includes side panels, diff views, inline Mermaid diagrams, information widgets, custom scrolling, and real-time rendering. The project supplies a Mermaid renderer without browser or TypeScript dependencies and publishes benchmarks covering RAM consumption, startup and input-readiness times, and memory scaling across multiple active sessions.

fast-jev-compaction is an npm library and Claude Code plugin that compacts tool-call history without rewriting the original text. It pairs each tool call with its result, sends the conversation state and questions about each non-pinned call to Jev, and then keeps the call and result, keeps only the call while truncating the result, or removes both according to Jev's scores. Recent messages and the first message are pinned; state fitting progressively truncates inputs, abridges long text, collapses older messages, and reduces old tool calls to one-line records so requests fit within configured token estimates. User and assistant text is never removed or shortened in the returned transcript, and retained content stays verbatim. The package exposes compaction, decision, batching, state-fitting, and transport-building functions, while the Claude Code hook replaces built-in compaction and falls back to Claude Code's summary when Jev fails or reduction is insufficient. It uses the TypeSafe API by default and requires a TypeSafe API key.

jq is a lightweight command-line JSON processor for slicing, filtering, mapping, and transforming structured data. It can compose and pipe JSON output, including results from MCP clients such as mcpc, using an expression language modeled in part on tools such as sed, awk, and grep. jq is written in portable C, has no runtime dependencies, and is distributed as a standalone binary for multiple platforms.
