Engineers get a fast, precise workspace. Everyone else gets an AI studio that turns plain English into queries, charts, and answers — in the same app.

One connection, one source of truth — with two front ends over it. A precise workspace for when you want to write queries yourself, and a plain-English chat that writes them for you. Switch in the header anytime; the guardrails never change.
When you know exactly what you want
A fast, keyboard-driven workspace with everything you expect from a serious MongoDB client — plus an AI co-pilot living in the shell.
When you'd rather just ask
Chat with your data in plain English. Studio writes the query, runs it, charts it, and explains it — across one collection or your whole database.
Collapsible, type-colored JSON that's ObjectId- and date-aware, or a typed table with a sticky _id.
Field · operator · value rows with autocomplete from your latest 1,000 docs. Drop to raw JSON anytime.
Enable, disable and reorder stages with run-to-stage previews. Copy as shell or eject straight into it.
Index usage, docs-vs-keys examined, timing — and a verdict in English: “collection scan — add an index.”
Sample a collection and see every field, its types, fill-rate %, and example values at a glance.
Credentials AES-256-GCM encrypted; one toggle moves the key into your OS keychain. Secrets never return to the UI.
Open several servers as live workspaces and switch between them in a click — each keeps its own tabs and sidebar, and reconnects right where you left off on launch.
Move connections between machines — portable without passwords, or a passphrase-encrypted backup that carries credentials safely. Copy any connection string in two clicks.

]Grab the build for your OS. Installed apps update themselves from GitHub releases — so you only do this once.
Download the right build
Apple menu → About This Mac. Apple M1/M2/M3/M4 → the aarch64 .dmg; Intel → the x64 .dmg.
Install
Open the .dmg and drag Ognom into your Applications folder.
Clear Gatekeeper — one command
Ognom is open source and distributed outside the App Store, so macOS quarantines the download. The step that works on every Mac — and is required on Apple Silicon — is to strip that flag. Open Terminal and run:
xattr -dr com.apple.quarantine /Applications/Ognom.appThen double-click Ognom in Applications. That's it — you only do this once.
Because the app isn't signed with a paid Apple Developer certificate, Apple Silicon shows “Ognom is damaged and can't be opened.” — and right-click → Open / “Open Anyway” can't bypass that damaged verdict (Apple Silicon strictly enforces code signatures). The xattr command removes the download flag so macOS treats the app like one you built yourself. On an Intel Mac you'll instead see “unidentified developer” — there, right-click → Open works too.
Click the connection name (top-left) → New connection. Paste a connection string, or fill in host / auth / TLS under Advanced. Standard & mongodb+srv, replica sets, SCRAM, X.509, LDAP, custom CA — all supported. Connect to more servers anytime and switch between them from the same menu.
Click a collection in the sidebar, or press ⌘K to jump by name. Browse documents, build queries visually, and assemble aggregation pipelines.
Flip the header switch to Terminator, pick a database + collection (or Whole database), and type a question. Studio writes the query, runs it, and charts the answer.
Studio and the Shell assistant use OpenAI. Go to Settings → Prompts & AI and paste your key — it's stored locally and sent only to api.openai.com from Ognom's backend, never through the web layer.
The ? in the header opens an in-app Help page with guided examples for both developers and product owners. You're never stranded.
Ognom is a local desktop app. Your queries go to your MongoDB server; Studio's prompts go only to your configured AI provider, using your key. No middleman, no account, no telemetry.
Read the full model ↗AES-256-GCM at rest
Connection secrets are encrypted on disk. The UI never receives stored passwords back.
OS keychain, optional
One toggle moves the master key into the macOS Keychain / Windows Credential Manager / Secret Service.
Safe by construction
Strict CSP, no remote content, results capped, and Studio can never write from a prompt.
No license keys, no locked “premium” tabs, no account. Just a good MongoDB client.
