maestro-career-studio

Stop rewriting your resume for every job.

Maestro tailors it from your whole career history in under a minute, and every bullet is something you actually did, so you can defend it in an interview.

• Same score, every time. The match score runs on fixed rules and a small model on your own computer, with no AI service involved. Same resume, same job, same number.
• Every AI edit is a diff. Suggested changes arrive as a before and after. You accept or undo them one by one.
• It fills the form and stops there. The Companion fills job applications from your saved answers and attaches your resume. It never submits. That click is yours.

Install in two commands, or follow the Getting Started guide if this is all new to you.

Works with Claude, Codex or the ChatGPT desktop app (88 tools) · bring your own AI key, OpenAI, Gemini or Claude (scoring, PDFs and tracking work without one) · real LaTeX and Typst PDFs · runs on your computer, no account · take everything with you in one career.md file

Made for one person on one computer. There is no login, so anything that can reach the app can read and change your whole career record and your saved API keys. Out of the box it only listens on your own machine (127.0.0.1). Never expose the app to a network. The one published path is /api/sync, sealed, and only as sync setup describes. SECURITY.md has the details. Your career record stays on your computer. When you use AI features, resume and job information goes to the AI service you choose.

Why it works this way

If your resume folder has a v2finalcopy(3) in it, this is for you. Maestro keeps one record of what you have actually done, and every resume is a view of that record. Approved bullets go into a resume word for word, and rewording one is a separate step that asks you first. When a job asks for something your resume does not show, Maestro asks you about it. If it is true, it is saved for every future application. If it is not, it stays a gap.

The score is fixed rules, so the same resume and job always get the same number. It is not an employer's score or a prediction of an interview, so use it to compare your own drafts. Saving a job and tailoring for it took about 10 seconds on Gemini and about 40 on the OpenAI default in our tests, at about a penny (OpenAI) or under 3¢ (Gemini) per application (the numbers).

Nothing here is rented. It is free and open source (Apache 2.0), with no account, and you pay only for the AI you use. Your career has one history. Your resume should too.

The long version, with the score, tailoring, templates and the rest of the toolkit, is in Using Maestro CS.

Quickstart

Install uv once. After that, Maestro is two commands: no Docker, no Git, no clone. uv installs Maestro as a single maestro command and fetches the Python it needs, and the package brings its own web app and its own Node. It runs on macOS, Linux and Windows (x64).

# 1. Install uv once, then open a new terminal.
curl -LsSf https://astral.sh/uv/install.sh | sh     # macOS and Linux

# On Windows, in PowerShell instead of the line above:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# 2. Install Maestro, then start it.
uv tool install --python 3.12 maestro-career-studio
maestro start

maestro start runs Maestro in the background and opens http://localhost:3000. Closing the terminal does not stop it. The first start downloads the small scoring model (about 100 MB, once) from Hugging Face, so allow a minute or two. If the terminal says maestro is not found, run uv tool update-shell and open a new terminal.

Best effort, not tested: Windows on ARM has no PDF-engine (typst) wheel, so install an x64 Python under emulation: uv tool install --python cpython-3.12-windows-x86_64-none maestro-career-studio. Alpine and other musl Linux are not supported by the PDF engine's wheels; use a glibc distro or Docker.

Then:

1. Add your AI key in Settings › AI & models. One key from OpenAI, Gemini or Claude is enough. Without a key, scoring, PDFs and tracking still work (what a key costs and does).
2. Import your resumes, save a job, and tailor (step by step).
3. Optional: maestro connect adds Maestro to Claude Desktop, Claude Code, Codex, Cursor or VS Code, and the Companion is a Chrome side panel for saving and filling job pages.

Command	What it does
maestro start	Start Maestro and open the app (--no-browser, --skip-model)
maestro stop	Stop it
maestro status	Whether it is running, its version and whether a newer one exists (--offline skips that check, --json for scripts; exit code 3 means stopped)
maestro update	Save a snapshot of your data, update, restart (-y skips the question)
maestro connect [app]	Add Maestro to Claude Desktop, Claude Code, Codex, Cursor or VS Code
maestro import-docker CHECKOUT	Move your data from a Docker install into this one, once (--dry-run shows the plan; steps)

The full command table also covers logs, open, restart, autostart, backup, uninstalling and TeX for LaTeX templates. What the command contacts, and when: PRIVACY.md.

Young, but rehearsed. The app runs daily on my machine. A fresh Docker install (clone, start, first tailored resume) has been checked end to end on a second machine, and CI installs and starts the uv package on macOS, Linux and Windows for every change. It has had little testing on machines that aren't mine. If it fails on yours, please open an issue with the log. That report is one of the most valuable contributions there is.

Alternative: run with Docker (self-hosters)

Docker stays the route for contributors and for servers. It needs Docker, Git and about a 1 GB download (roughly 3–4 GB unpacked); the prerequisites have the detail, and on Windows you run it under WSL (steps).

# 1. Download the project and create your settings file
git clone https://github.com/seinun-ai/maestro-career-studio.git
cd maestro-career-studio
cp .env.example .env

# 2. Start the app (downloads about 1 GB the first time)
docker compose up -d

Then open http://localhost:3000 and add your AI key in Settings › AI & models. The first start sets up your database and adds a demo resume so you have something to look at. The rest of the Docker route is in the setup reference.

Docker and uv are separate copies. They keep separate data, and both want ports 8001 and 3000, so run one at a time. Moving from Docker to uv? Stop Docker, install Maestro as above, then run maestro import-docker CHECKOUT once (steps). It reads your Docker folder and changes nothing in it.

Working with AI assistants

Driving it from Claude, Codex, or ChatGPT (MCP)

MCP is the connector that lets an AI assistant use the app for you: read a posting, score it, work the gaps, make the PDF, all in conversation, on your computer against your data. All 88 tools are on by default, and smaller tool sets (hunt, apply, explore, templates, career) keep a chat focused. On a uv install, run maestro connect; otherwise open Settings › Connected agents › Connect an agent app. Setup, example prompts, tool sets and the ready-made skills are in Using Maestro CS and the MCP guide. An always-on bot can work your search while your laptop is off.

Going all the way: agent applications

Maestro CS can take an application right up to the submit button, and it stops there. A job your agent finds becomes a proposal. You review proposals in the Agent inbox and queue or skip them, and an apply run works only the ones you queued. It waits for your yes before each submit, and nothing is ever submitted from the web app itself. That yes is recorded by the agent, so it is an audit trail and a volume limit, not a lock that a manipulated agent can't pick: run it while you're watching. The risks, plainly: a job posting is untrusted text that can try to instruct the agent reading it, a posting the agent found is not a vetted employer, and we won't help you hide automation from bot detection. Read the full section before you turn it on.

Updating

Installed with uv? Run maestro update. It checks PyPI for a newer release, prints any breaking changes from the changelog, saves a verified snapshot of your data, stops Maestro, updates it and starts it again.

On Docker? From the folder you cloned, run ./scripts/update.sh (--check only tells you whether you're up to date). It needs bash, so on Windows run it under WSL.

Your data is not touched by an update, and deleting the project folder does delete it on the Docker route. After updating, reload the browser extension and restart your AI assistant so it sees new tools. docs/UPDATING.md has the rest: updating by hand, pinning a version, what the backup covers, rolling back, and coming from v0.3.0 or older.

Where your files live

A uv install keeps everything in one folder per user: the database, resumes, settings, backups, logs and maestro.env (your API keys and, if you need them, port overrides). Deleting the folder deletes your data.

System	Folder
macOS	~/Library/Application Support/Maestro Career Studio
Windows	%APPDATA%\Maestro Career Studio
Linux	$XDG_DATA_HOME/maestro-career-studio (default ~/.local/share/maestro-career-studio)

Finished resume PDFs are also copied to Documents/Maestro Career Studio/Applications, one folder per job (Settings › Tailoring › Resumes folder).

On the Docker route everything stays inside the folder you cloned (data/, base_resumes/, applications/, settings/ and more; the full list). Your files are yours, never uploaded. Every application's PDF is saved in applications/, and career.md exports your whole career history as one Markdown file.

Troubleshooting

maestro status and maestro logs come first, and a port already in use is named in the message. maestro check prints the install's facts as JSON to paste into an issue. Ports, API keys and quota errors, "database is locked", PDFs that fail to build and an empty app after updating are covered in Troubleshooting & Common Questions.

Privacy Policy

There is no Maestro CS server or account, and the author never receives your data. Your career record stays in files on your computer; it goes to an AI service only when you add a key and use an AI feature, and to the assistant you connect over MCP when it calls a tool. With a model on your own computer, the app sends nothing out. PRIVACY.md has the full policy: what is stored, every place data can go, retention, and how to ask a question.
