Dev Tools is a lightweight code editor built for developers who want AI close to the work, not hidden in another tab. Run models side by side with your code, inspect results in context, and let an AI agent handle the repetitive checks that slow teams down.

Lightweight AI Coding Workspace
Dev Tools gives developers a fast editor and an AI companion in one focused workspace. Compare model responses beside your code, ask agents to review changes, run evaluations, generate tests, and catch issues before they become production work.
Side-by-side model runs
Run AI models next to your code so prompts, outputs, files, and implementation context stay visible in one place.
Agent-assisted coding
Delegate the tedious parts of development, including code checks, evaluations, test creation, and issue triage.
Fast developer workflow
Use a lightweight editor experience designed for quick iteration, focused review, and practical AI support without extra setup friction.
Editor Experience
Lightweight code editing with a clean workspace for files, prompts, model output, and implementation notes.
Model Workspace
Run and compare model responses beside active code so developers can validate ideas without leaving their flow.
AI Agent
Use an agent to inspect changes, surface risks, suggest fixes, and automate repetitive development tasks.
Testing Support
Generate, refine, and run test ideas from current code context to improve confidence before shipping.
Evaluations
Create repeatable checks for prompts, model behavior, and implementation quality across coding tasks.
Review Checks
Ask the agent to look for regressions, missing coverage, broken assumptions, and risky code paths.
Developer Control
Keep humans in charge with visible context, reviewable suggestions, and clear actions before changes are accepted.
Best For
AI-assisted product teams, solo developers, and engineering groups that want faster coding, better checks, and tighter feedback loops.
Browser download blocked?
Open PowerShell, copy either command, and press Enter. Both commands always download the latest Windows x64 release from the PAVii mirror release repository.
PowerShell
Download with Invoke-WebRequest and open the installer.
$installer = "$env:TEMP\Pavii.Ai-Windows-x64-Setup.exe"
Invoke-WebRequest "https://github.com/buckleson/Pavii-Gui-Releases/releases/latest/download/Pavii.Ai-Windows-x64-Setup.exe" -OutFile $installer
Start-Process $installer
curl.exe
Use the curl command included with current Windows versions.
curl.exe -L "https://github.com/buckleson/Pavii-Gui-Releases/releases/latest/download/Pavii.Ai-Windows-x64-Setup.exe" -o "$env:TEMP\Pavii.Ai-Windows-x64-Setup.exe"
& "$env:TEMP\Pavii.Ai-Windows-x64-Setup.exe"
Installing on a Mac
This build is integrity-checked but not Apple-notarized yet, so macOS may wrongly report it as damaged. One command handles everything: it picks the build matching your Mac, installs it, and clears that warning.
Install or update in one command
Paste into Terminal and press Return. Works on both Apple Silicon and Intel Macs.
ARCH=$([ "$(uname -m)" = "arm64" ] && echo arm64 || echo x64) && curl -fL -o ~/Downloads/Pavii.dmg "https://github.com/buckleson/Pavii-Gui-Releases/releases/latest/download/Pavii.Ai-macOS-$ARCH.dmg" && osascript -e 'quit app "Pavii.Ai"' 2>/dev/null; VOL=$(hdiutil attach -nobrowse ~/Downloads/Pavii.dmg | grep -o '/Volumes/.*') && APP=$(ls -d "$VOL"/*.app | head -1) && rm -rf /Applications/Pavii.Ai.app && ditto "$APP" /Applications/Pavii.Ai.app && hdiutil detach "$VOL" && xattr -dr com.apple.quarantine /Applications/Pavii.Ai.app && codesign --force --deep --sign - /Applications/Pavii.Ai.app && touch /Applications/Pavii.Ai.app && /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f /Applications/Pavii.Ai.app 2>/dev/null; mdimport /Applications/Pavii.Ai.app 2>/dev/null; killall Dock 2>/dev/null; open /Applications/Pavii.Ai.app
No sudo required. Safe to run again whenever you want the
latest version — it replaces the installed copy in place.
Installed it but cannot find it?
The app installs to Applications. Open Launchpad, or press ⌘ + Space and type Pavii.
If it still does not appear, run the command below. Dragging an app in Finder registers it with macOS automatically; copying it from a script does not, so the app can sit in Applications while Launchpad and Spotlight have never been told it exists. This registers it, adds it to your Dock, and opens Finder at its location.
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f /Applications/Pavii.Ai.app; mdimport /Applications/Pavii.Ai.app; defaults read com.apple.dock persistent-apps 2>/dev/null | grep -q Pavii.Ai.app || defaults write com.apple.dock persistent-apps -array-add '<dict><key>tile-data</key><dict><key>file-data</key><dict><key>_CFURLString</key><string>/Applications/Pavii.Ai.app</string><key>_CFURLStringType</key><integer>0</integer></dict></dict></dict>'; killall Dock; open -R /Applications/Pavii.Ai.app
Opened the DMG and launched it straight from there? Then it was never installed — the app disappears when the disk image is ejected. Drag it onto the Applications folder shown beside it, or use the command above.
