# Ataraxy Labs > Software, written by the things that read it. Ataraxy Labs builds the substrate for agent-native software development: semantic version control (sem), entity-level merge (weave), semantic code review (inspect), and a tmux sidebar for agent orchestration (opensessions). Every tool in software development was designed for human hands. We work one layer down — at the entity (function, class, method, config key), not the line. The site is agent-addressable: every HTML page has a `.md` twin at the same path (e.g. `/sem` ↔ `/sem.md`). ## Products - [sem](https://ataraxy-labs.com/sem.md): Semantic version control — entity-level diffs, blame, and impact analysis on top of git. Ten languages via tree-sitter. Source: https://github.com/Ataraxy-Labs/sem - [weave](https://ataraxy-labs.com/weave.md): Entity-aware git merge driver — resolves the false conflicts git invents when independent agents edit the same file. ~95% reduction vs. line-based merge. Source: https://github.com/Ataraxy-Labs/weave - [inspect](https://github.com/Ataraxy-Labs/inspect): Semantic code review — triages PRs by structural risk using entity graphs and LLMs that read for meaning. Built on sem-core. - [opensessions](https://github.com/Ataraxy-Labs/opensessions): tmux sidebar for orchestrating coding-agent sessions (Amp, Claude Code, Codex, OpenCode) with per-thread markers and a local HTTP API. ## Writing - [Stop Grepping, Ask the Compiler](https://ataraxy-labs.com/blogs/stop-grepping.md): Agents grep when the compiler already knows everything about every function. The case for LSP-native code intelligence. - [Code is not text.](https://ataraxy-labs.com/blogs/code-is-not-text.md): Git tracks lines. Code has structure that text doesn't — the case for a semantic layer above git. - [The Entity](https://ataraxy-labs.com/blogs/the-entity.md): The right unit for code intelligence isn't the character, line, or file — it's the entity. - [What if Merges Understood Your Code?](https://ataraxy-labs.com/blogs/what-if-merges-understood-code.md): A git merge driver built for a world where agents write most of the code. ## About - [Manifesto](https://ataraxy-labs.com/manifesto.md): Positioning, axioms, and principles. - [Team](https://ataraxy-labs.com/team.md): Two people, the whole stack. - [Community](https://ataraxy-labs.com/community.md): What users say about the work. ## Optional - [Homepage (Markdown)](https://ataraxy-labs.com/index.md): Condensed home with thesis, product list, and axioms. - [Writing index (Markdown)](https://ataraxy-labs.com/blogs.md): All essays in one file, with excerpts and dates. ## Contact - hello@ataraxy-labs.com - https://github.com/ataraxy-labs
