Ship with Confidence
AI commit message, AI PR description. Push and merge — the loop is complete.
Built different.
A visual commit graph, a smart clipboard, AI code review, and a recovery vault — all native, all in one workspace.
Zion Tree
Lane-colored commit graph with search, jump bar, and keyboard navigation
Smart Clipboard
Auto-categorizes commands, paths, hashes, URLs, images — click to paste
AI Code Review
Pre-commit review catches bugs, security issues, and code smells
Recovery Vault
Auto-snapshots before destructive operations — restore in one click
Everything in one window.
Graph, editor, terminal, and operations — plus capabilities you won't find anywhere else.
Zion Code
Your AI agents build. You review.
The terminal is where development happens now. Run AI agents in multitab/multisplit terminals with ANSI/256/TrueColor support, independent zoom, and inline graphics. The editor is a lightweight companion — syntax highlighting, Git Blame, Quick Open, formatter for 16+ languages — so you can inspect and verify what AI built. Not a full IDE with dozens of plugins. That's intentional.
Zion Tree
See your project's topology
Color-coded branch lanes with Bezier merge curves that make even complex histories legible. Search commits, jump to any branch, see pending changes at the top, verify GPG signatures — and navigate it all with your keyboard. Up to 5,000 commits, paginated and smooth.
Operations Center
Every Git operation, visual
Stage individual hunks or specific lines within a hunk — atomic commits become easy. Drag-and-drop interactive rebase. Branch, tag, stash, cherry-pick, revert, reset. Worktree management with smart naming. Force push with lease. Everything you'd do in the terminal, but you can see what you're doing.
Smart Clipboard
Stop switching apps. Start dragging.
You're building something. You need to give the AI visual feedback. Take all the screenshots you need (Cmd+Shift+4), come back to Zion — every capture is waiting with thumbnails. Drag any of them into any split terminal. Errors, layouts, logs, UI bugs — the clipboard is always there, always ready. Plus: copy a git hash and Zion offers "Show in Graph". Copy a branch — one click checks it out. Copy a command — double-click executes it.
Conflict Resolution
Built-in resolver with AI guidance
Merge conflicts open a dedicated resolver with side-by-side diffs and one-click actions: accept ours, theirs, both, or edit manually. With AI enabled, it reads both sides and proposes the semantically correct merge with reasoning. Once resolved, the operation auto-continues.
Mobile Remote Access
All your sessions, from your phone
Scan a QR code. Your phone shows live terminal output from every open project — with full ANSI colors. Approve or deny AI prompts remotely. Send commands. Switch sessions. AES-256-GCM encrypted over Cloudflare Tunnel or local Wi-Fi. Walk away from your desk without losing control.
Recovery Vault
Be aggressive with git. Zion has your back.
Before every destructive operation — reset --hard, interactive rebase, discard all — Zion silently snapshots your working tree. If something goes wrong, restore in one click. Named refs like zion-pre-reset-hard so you always know what happened.
And more
Zion Bridge
Switch LLMs without friction.
You know a certain LLM is better at specific tasks. Bridge transfers your AI config instantly so you can switch mid-project. Hit your limit on Claude? Switch to Gemini and keep going — Bridge gets you ready in one click. Visual migration console with confidence levels and selective sync. Supports Claude, Codex, Gemini, and Cursor configurations.
Voice-to-Terminal
Speak, execute.
Press the shortcut, speak a command, watch the floating glassmorphic pill animate with real-time waveform bars. Apple Speech (free, instant) or OpenAI Whisper (higher accuracy). Your words go straight to the terminal.
Zen Mode
Full focus. Zero distractions.
Full-screen editor and terminal with transparent background. Everything else disappears. Clipboard stays accessible via toolbar popover. Toggle with one shortcut.
15 AI features. 3 providers. Your key.
Claude, GPT, or Gemini — bring your own API key. Stored in macOS Keychain. Falls back to smart heuristics when AI is off.
Smart Commit — AI writes the message from your diff
Smart PR — AI drafts the pull request from your commits
Semantic Search — ask your git history in plain English
Commit Messages
AI reads your diff, your branch name, and your recent commit style — then writes the message. Compact or detailed. Never sounds like a robot.
Pre-Commit Review
Hit commit, AI reviews your diff first. "Removed null check before database query — SQL injection risk." Fix it before anyone sees it.
Diff Explanation
Intent, risks, and narrative for every change. Color-coded risk badges: Safe, Moderate, Risky. Auto-explain mode analyzes as you select files.
Conflict Resolution
AI reads both sides of a merge conflict, understands the code, and proposes the semantically correct merge — with reasoning.
Semantic Search
Ask your git history in plain English. "When did we change the auth flow?" — AI finds the commits, highlights them in the graph.
Blame Explainer
Click any blame line. AI tells you WHY that code was changed — not just who wrote it and when, but the actual reasoning from commit context.
PR Description
Auto-generate title and body from your commit log. Dynamic base branch selection. One click from staged changes to a ready PR.
PR Inbox
Assigned PRs appear with severity badges. AI auto-reviews them. Push notifications to your phone via ntfy when review completes.
Changelog Generator
Pick a commit range, get categorized release notes: Features, Fixes, Improvements. Copy or export as markdown.
Branch Summarizer
Right-click any branch: "One-sentence summary." Instantly know what a branch does without reading every commit.
Commit Split Advisor
Large staged diff? AI suggests how to split it into atomic commits with clear boundaries. Better history, cleaner PRs.
Stash Messages
AI writes descriptive stash messages so you actually remember what you stashed three weeks ago.
Pending Changes Summary
One click: AI summarizes what you've been working on across all changed files. Use it as a commit message or just to remember where you left off.
Bisect + AI Culprit
Visual binary search for bugs. When the culprit commit is found, AI explains what changed and why it likely caused the regression.
Branch Diff Review
Select source and target branches, get a full AI review with per-file findings, risk badges, and exportable markdown — before you merge.
Your AI subscription, your repo, one window.
Zion Talks turns Zion into a true AI development workspace — six providers in one chat, an embedded MCP server that exposes your live repo state to every agent, plan mode that previews changes, and an edit harness that auto-commits with a recovery snapshot. The patterns the field converged on in 2026, wired into the same window where you read diffs, run your terminal, and ship code.
Zion Talks — multi-provider chat with live tool calls, cost meter, and thread history.
Bring your own subscription
Claude Pro and ChatGPT Plus you already pay for — Zion spawns the CLIs and lets you chat through them without an API key.
Auto provider routing
Pick "Auto" in the composer and Zion picks the best provider per task with quota + cost fallback. Out of Claude credits? It tries OpenAI, then your local model — surfaces the switch in a slim banner.
Git-aware MCP server
Built-in MCP server exposes live git state — staged hunks, branches, commit history, repo map — as tools every agent can call. API providers get the same tools via a universal tool bridge.
Plan mode + Edit harness
Previews structured plans before edits land. SEARCH/REPLACE blocks stream as per-block diff preview cards with Apply / Reject / Apply-all. Recovery vault snapshots before every apply, auto-commit with aiedit: prefix.
Cost + tokens in the header
Live USD pill (Claude) and token meter (every provider) per thread. Daily cost cap per provider in Settings — Auto routes around exhausted budgets until midnight.
Sessions persist by repo
Per-repo SQLite-backed thread sidebar. Resume claude / codex sessions across launches — follow-up turns reuse the same server-side context without reburning prompt cache.
Beautiful by design.
From deep indigo to clean light to full cyberpunk neon. Every theme is hand-tuned for editor and terminal.
1function calculateLanes(commits) {2 const lanes = new Map();3 let nextLane = 0;45 for (const commit of commits) {6 if (!lanes.has(commit.branch)) {7 lanes.set(commit.branch, nextLane++);8 }9 commit.lane = lanes.get(commit.branch);10 commit.color = LANE_COLORS[commit.lane % 6];11 }1213 return commits;14}
“Zion is the highest point in the canyon — where you can finally see everything at once.”

Run multiple AI agents in parallel — each in its own worktree, each on its own branch, each visible in a split terminal. See what every agent is building without switching windows.
Review
AI explains every diff. Pre-commit review catches bugs. Visual graph shows exactly what changed and where.
Ship
AI writes the commit message. AI drafts the PR. Stage hunks, resolve conflicts, push — all from one place.
Anywhere
Approve AI prompts from your phone. Monitor terminals remotely. Recovery Vault protects you while you're away.
Why I built Zion
I missed control. The ability to see what each LLM is doing, organize outcomes across branches, and manage workspaces with full visibility. So I started with a Git client — and kept going. The terminal is where development happens now. The editor helps you review. The AI runs the loop and you decide what ships. One window for all of it. Zion is the view from the top.

How Zion stacks up.
IDEs and AI editors are great for agentic coding. Zion is the workspace that shows you everything at once.
When you're running multiple AI agents across worktrees and branches, you need more than an editor — you need a workspace with full visibility into what each agent is doing.
