LatexTerm

A native macOS terminal for working with Claude Code and Codex. Panes that aren't only terminals — sketches, PDFs, live web pages — sit next to the chat, and math renders as math.

_{Real sessions, recorded in LatexTerm. Only the waiting while Claude thinks is cut out.}

Sketch it, hand it over

Draw on the scratchpad, press ➤ — the sketch lands in Claude's prompt as an image. Claude draws the clean version straight back onto the pad.

Your PDF, next to the chat

Claude compiles and opens the preview. Mark a passage, add a note, send — with page, source line and a crop. The PDF reloads in place when the fix lands.

Your site, live

Dev server in one pane, the page in a web pane. ⌥-click any element and ⇧⌘⏎ hands it to Claude — with selector and source line. Agents see and click the page themselves.

Claude starts Claudes

Ask for parallel work and it happens side by side. Every pane reports what it is doing in the title bar; unwatched panes send a notification when they finish or need you.

Home: every project, every session

⌘N opens Home: projects, sessions, quotas. Resume where you left off, or just start typing to search across sessions and open one beside the other. Claude and Codex are equal citizens.

Also in the box

• LaTeX over the terminal text — $…$, $$…$$, \(…\), \[…\] render with KaTeX exactly on their characters. Hover to enlarge, click to pin and copy as LaTeX, readable Unicode, PNG, vector PDF or Markdown; ✎ edits a formula and types it into your prompt.
• Auto-tiling panes and tabs — ⌘T splits into a balanced grid, ⌘⏎ zooms, ⌥⌘R restarts and brings every pane and agent session back.
• Built for agents — a latexterm CLI and an MCP server let Claude and Codex open panes, start and ask other sessions, and look at what a pane shows. → docs/agents.md
• Looks like Ghostty — Ghostty themes and one-click config import. → docs/appearance.md
• Desktop widgets for quotas, what's due and today's numbers.

The interface is German for now.

Install

Grab LatexTerm.app from Releases, unzip, drop into /Applications. The build is not notarized — on first launch open System Settings → Privacy & Security → Open Anyway, or:

xattr -dr com.apple.quarantine /Applications/LatexTerm.app

Let agents drive it (optional):

ln -s /Applications/LatexTerm.app/Contents/Helpers/latexterm /opt/homebrew/bin/latexterm
claude mcp add -s user latexterm -- /opt/homebrew/bin/latexterm mcp

Home reads its projects from an external projekte --json command; without it the pane shows a hint and nothing else breaks. Codex status hooks: docs/agents.md.

Build from source

Needs Xcode 26+ with the Metal Toolchain (xcodebuild -downloadComponent MetalToolchain).

open LatexTerm.xcodeproj    # then Cmd+R  (App Sandbox is off on purpose: PTY rights)

# CLI build + tests
xcodebuild -project LatexTerm.xcodeproj -scheme LatexTerm -configuration Release \
  -derivedDataPath .build CODE_SIGNING_ALLOWED=NO build
xcodebuild test -project LatexTerm.xcodeproj -scheme LatexTerm \
  -destination 'platform=macOS' CODE_SIGNING_ALLOWED=NO
bash scripts/test-regressions.sh
