Describe the outcome; the right agents pick it up. Big jobs split across a team working side by side — one drafting, one in the browser, one pulling numbers — each a session you can open and read. Nothing happens off-screen.
One dispatch. A window of agents — any CLI you already use.
A real browser, built in. Agents open the site, click through, fill the form, post, extract — you watch every move and take the wheel at logins in one click. And a browser task that works can go on the clock.
It sets up your services, works inside your guardrails, and stays in your brand's voice.
The Monday review. The metric pull. The inbox triage. Set the schedule and the budget; loops run the routine — browser included — show you every run, and never overspend a limit you set.
The morning report writes itself. Set it once — it keeps going.
Every file your business touches lives here — docs, decks, sheets, images, PDFs — previewed in place, no app-hopping. And it all links into a living map that compounds: by month three it answers with your history, your numbers, your reasons. Plain files on your disk, yours to walk away with.
Everything your company knows — filed, findable, and drawn as one connected map.
Hold the key and talk — dispatch the agents, brainstorm a plan out loud, ask what changed today. Orchestrate the whole operation by voice, hands off the keyboard, and every word still lands in the vault as a plain file you own.
Speak to G-Force — it answers, drives the app, and keeps working while you talk.
Point each job at the model that's best for it — one for the careful writing, another for a fast pass, whichever you trust with the numbers. Bring your own key and pay the makers directly with no markup, and switch anytime. No single lab owns your operation.
Anthropic, OpenAI, xAI, Google, or open source — every job routed to the model best for it, never locked in.

Digital? Spec it and build it in the workspace. Physical? Hunt it down in the browser — suppliers, samples, listings. Then the same place creates the assets, writes the copy, and runs the launch. One thread, start to shelf.
ExploreProspects researched in the browser, every call and reply logged to the vault, follow-ups drafted the moment a deal goes quiet — and each send waits at the gate for your go.
ExploreA client brief becomes a task list routed across agents. Linear and Notion stay current as work lands, and the status update is drafted from what actually got done.
ExploreInvoices drafted on schedule, receivables chased, subscriptions and spend tracked in one record — and nothing gets sent or paid without your approval.
ExploreThe calendar ships itself: posts drafted from the work that actually happened, published through the browser after your gate, results filed back into the vault.
ExploreYour vault already holds the brand, the voice, and the assets. Agents cut it into posts, pages, and campaigns — generated from what's real, published through the browser after your gate.
ExploreCustomer questions answered in your voice, drafted from the vault's real product knowledge. Every reply waits at the gate until you've seen it — and every answer files back in.
ExploreYou already know how to get good work out of Claude, Codex, Gemini, or other AI models. The ceiling appears when you're still carrying context between chats, assigning every next step, reopening the same tools, and rebuilding the same workflow next week.

Keep the intelligence you trust.
Replace the manual orchestration.
You at the top. Your agent crew under you. One governed operating layer — files, terminal, browser, apps, loops — acting on the world. And everything it learns settles into the vault.

SynthOS is a native macOS app that staffs your business with AI agents that do real work on your Mac — they write, browse, build, and file. Everything they produce lands in a plain-markdown vault you own: a living, linked map of your tasks, deals, contacts, and decisions that compounds with every day you use it.
Unlike chat tools that talk but never do, terminal agents built for engineers that forget when the window closes, and cloud platforms that keep your data on someone else's server, SynthOS runs the same class of frontier agent — pointed at your whole company, on your own machine. A built-in browser clicks and posts for real, terminals build in the open, and connected apps like Slack, GitHub, Notion, and Linear let agents work where your business already lives.
It's native and bring-your-own-key: pay the model makers directly with no markup, or run on SynthOS credits. Every move an agent makes is a visible receipt, and anything that ships — a send, a publish, a spend — waits for your approval. Download free, work fully, and grow when the work earns it.
