What you get
- A browser agent on any site. It reads the page, clicks, fills forms, navigates, takes screenshots and understands them with a local vision model, and reports back in the side panel.
- Documents and research. Reads PDFs open in a tab, searches the web when a fact is needed, and writes reports, briefs and reviews with citations.
- The ServiceNow toolkit, when you work there. Reads and writes records through the tab you are already signed into, builds and publishes legacy workflows, reviews scripts, runs post-deployment checks, and grounds its code in the official API reference, which ships inside the zip.
- Knowledge-work packs. Knowledge articles, inbox reply drafts, meeting follow-ups, contract review, RFP responses. Drafts only; nothing is sent without your explicit approval phrase.
- Local files. Connect folders and it reads, writes and exports (.md, .docx, .pdf) on your disk.
- Your choice of models. Local Ollama by default. OpenAI, Gemini, Claude, Grok, Ollama cloud or any OpenAI-compatible endpoint when you add your own key.
- 12 months of new versions, then $50 a year if you want to keep downloading them. The copy you installed keeps working either way.
Minimum computer
Local models need memory, mostly on the graphics card. Pick the row that matches your machine and install those models in step 1.
| Setup | RAM | GPU memory | Models | What to expect |
|---|---|---|---|---|
| Light | 16 GB | 8 GB (RTX 3060 / 4060) or Apple Silicon with 16 GB | qwen3:8b + qwen2.5vl:7b | Everyday page work, drafts and summaries. Slower on long documents and code. |
| Recommended | 32 GB | 24 GB (RTX 3090 / 4090 / 5090) or Apple Silicon with 32 GB+ | qwen3-coder:30b (18 GB) + qwen2.5vl:7b (6 GB) | The defaults. Every toolkit (documents, research, ServiceNow) at a comfortable pace. |
| Best | 64 GB+ | 32 to 48 GB, or Apple Silicon with 64 GB+ | qwen3-coder:30b + qwen2.5vl:32b (21 GB) | Sharper screenshot reading, longer documents, larger context. |
- Windows 10/11 or macOS 13+, Google Chrome 114 or newer, Ollama 0.6 or newer, about 40 GB of free disk for the recommended models.
- Without a GPU it still runs, but a step can take minutes instead of seconds. Not recommended.
- The first answer after a start is slow while Ollama loads the model (up to a minute); after that it is quick.
Install, A to Z
- Install Ollama from ollama.com/download, then pull the models for your row in the table above. For the recommended setup, in a terminal:
ollama pull qwen3-coder:30bandollama pull qwen2.5vl:7b.ollama listshows what is installed. - Let the extension talk to Ollama. Chrome extensions send an Origin header, so Ollama must allow it. Windows (PowerShell):
setx OLLAMA_ORIGINS "chrome-extension://*"· macOS (Terminal):launchctl setenv OLLAMA_ORIGINS "chrome-extension://*". Then fully quit Ollama (tray or menu-bar icon → Quit) and start it again. Skipping this is the number-one cause of "Ollama unreachable". - Download the zip with the button above (sign in, buy once, download any time). The zip is made for you: it carries your
license.json. - Unzip it to a permanent folder, for example
Documents\Agent Go Private(macOS:~/Documents/Agent Go Private). Chrome loads the extension from that folder every time it starts, so do not move or delete it afterwards. Inside you will find a folder namedagent-go-private; keeplicense.jsonin it. - Open the extensions page: paste
chrome://extensionsinto the address bar (Edge:edge://extensions, Brave:brave://extensions). - Turn on Developer mode, the toggle at the top right of that page (in Edge it sits in the left-hand panel).
- Click "Load unpacked" and pick the
agent-go-privatefolder, the one that containsmanifest.json. A card appears with the IDcdpinickmjdgbfnfkceknmidnfbllcjo. That ID is the same on every computer; any other ID means the wrong folder was picked ormanifest.jsonwas edited. - Pin it: click the puzzle-piece icon in the toolbar, then the pin next to Agent Go Private.
- Open the side panel: click the icon, or press Ctrl+Shift+L (macOS: Cmd+Shift+L). If the shortcut does nothing, another extension already uses it; assign one at
chrome://extensions/shortcuts. - Check the dot in the panel header: green means Ollama answered and your models are installed. Grey or red: open ⚙ Settings, confirm the Ollama URL is
http://localhost:11434and pick installed models from the lists. - Run your first task: go to any page, describe what you want in the side panel, press Enter. Type while it runs to steer it; ■ stops it.
Chrome shows a "Disable developer mode extensions" popup at each start while an unpacked extension is installed. Click Cancel (or the ×). It is expected for any extension installed this way, and it never affects the extension.
What it costs
- Agent Go Private, one-time
- $100
- New versions for 12 months
- included
- Renewal, 12 more months of versions (optional)
- $50
- Per turn, per page, per screenshot
- $0 — your hardware
One price for everybody, one computer per license for one person. The installed copy never expires when the version window closes; you only lose the ability to download newer builds until you renew. Cloud models, if you turn them on, are billed by that vendor to your own key.
Payment is handled by Stripe. The receipt comes from Stripe to the email of this account.
Updating
- Sign in here and download the new zip (while your 12-month window is open, or after a renewal).
- Empty the folder you installed from, then unzip the new files into that same folder. (A different folder would register a second, blank copy of the extension.)
- On
chrome://extensionsclick the reload arrow on the Agent Go Private card.
Your settings and shortcuts are kept; they live in Chrome's storage, not in the folder. The version you are running is shown at the top of the card on that page; this download is . The extension does not check for updates unless you turn on Settings → Check for new versions once a day; the check fetches one static file and sends nothing about you.
Uninstall
chrome://extensions → Agent Go Private → Remove, then delete the folder you unzipped.
Advanced: local machine bridges (optional)
Out of the box the agent works inside the browser tab. Two small servers you run on your own computer let it
go further: voice input transcribed locally, OS-level mouse / keyboard / screenshots for native apps, shell
commands (npm, git, tests, builds) in a project folder, and text from local PDFs. They answer only on
127.0.0.1, so nothing on your network can reach them, and every desktop action or command still asks for your approval in the side panel.
- Needs Windows with Python 3.10+ on PATH.
- Unzip anywhere permanent.
INSTALL.mdinside lists thepip installlines for each server. - Start
desktop-server\start-desktop.bat. It prints a desktop token; paste it in Agent Go Private → Settings, then switch on what you want (desktop control, Run commands) and click Test. - Start
whisper-server\start-whisper.batfor local voice input (the first start downloads the model).
Keep "Enable Run commands" off when you do not need it: commands run with your own user privileges, like a terminal. The token the desktop bridge prints is the only thing that stops other programs and web pages on your computer from using it; treat it like a password.
If something is off
- Header dot red, "Ollama unreachable" or a 403 — Ollama is not running, or step 2 was skipped. Set
OLLAMA_ORIGINS, quit Ollama completely, start it again, then reload the extension. - "model not found" — run
ollama pullfor the model named in Settings, or pick one of the installed models from the list. - Very slow, or the GPU runs out of memory — pick a smaller model from the table above, or lower the context size in Settings.
- "This copy is not licensed" —
license.jsonis missing from the folder. Download the zip again from this page (it includes it), or click Show my license key above and paste it in Settings → License. - Developer mode is greyed out, or the extension disappears after a restart — the browser is managed by an organisation policy that blocks unpacked extensions. Ask your IT team to allow it, or install on a personal profile or machine.
- "Manifest file is missing or unreadable" — the wrong folder was picked. Choose the
agent-go-privatefolder that containsmanifest.json, not the zip file or the folder above it. - The side panel is blank, or a step never finishes — on
chrome://extensionsclick the reload arrow on the card and open the panel again. If a page tool still misbehaves, reload that page too (Ctrl+F5). - It does not run on your machine after these steps — write to info@nowidevops.com within 14 days of purchase with your Ollama version and GPU; we get it running or refund the purchase.
Privacy
With the default provider the extension talks to two places: your own Ollama on localhost and the websites you ask it to work on.
It sends nothing to us: no page content, no screenshots, no usage data. Two things are optional and off until you turn them on:
a daily version check (one static file from this site) and cloud model providers (your key, stored only in Chrome on your machine).
Your license.json names you and your purchase date; keep the folder to yourself.
