What is an AI agent? A plain-English guide for business owners
What an AI agent is, how it works, where it helps a small business, the risks, and a 7-point check to see if you are ready for one.
A custom browser extension brings AI help directly onto the pages your team already works in, no app-switching required.
Your team spends the day inside web apps you do not control: a CRM, a supplier portal, an admin panel. This build creates a custom browser extension that brings AI help onto those exact pages, reading what is on screen and helping your team act on it. It is delivered as production code, ready to install privately or publish.

AI Browser Extension Assistant is a software build that creates a custom browser extension bringing AI help directly into the pages your team uses, delivered as production code ready to install or publish. It is tested on the real pages your team uses.
When the tools your team relies on cannot be changed, staff end up copying text between tabs, retyping details and checking the same things by hand. A browser extension puts AI help on top of those pages without touching the underlying software. That saves time on every record handled. The written scope sets the features, APIs, target pages and testing before you order, so a technical project still has clear limits.
A custom browser extension brings AI help into the pages your team already uses. Up to three features work in place, so nobody has to paste content into a separate tool.
Prompts and guardrails are configured for your rules and documented. Connections to up to two agreed APIs are built in, so the extension works with the services you choose.
The extension is tested on the real pages your team uses, with automated tests for core flows and thirty manual scenarios. The code is ready to install or publish.
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
| Option | Delivery time | Price |
|---|---|---|
| Standard | 20–30 working days | $4,900 |
| Express | 15–25 working days | $5,750 |
| Rush | 10–20 working days | $6,600 |
Before you start: Time the target tasks for a few staff and note which pages and tools they switch between.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
The build itself is a one-time payment, shown before you buy. Running the finished extension typically costs ~$50–300 a month for hosting and AI usage, on your own cloud account, depending on how many team members use it and how often.
AI usage during build and testing is billed the same way, so your cloud and AI provider accounts stay in your name.

Request a custom versionWe recommend monthly maintenance for this build. It covers monitoring, fixes and monthly change hours for adapting to a page layout change or making a small feature adjustment. The allowance scales with the build, and bigger changes go through a Change Quote. It starts after the included support period and can be cancelled any month.
$249/mo (the minimum fee, includes 2 change hours)
Optional. Starts after the post-launch support period. Cancel any month.
How maintenance works| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A generic AI browser extension charges a recurring subscription per user | A software agency quotes after a discovery and scoping phase | Ours is one fixed price, shown before you buy |
| Fit | A generic extension works the same way on every site, not tuned to yours | An agency build depends on what was agreed | Ours is built for the exact pages your team works in |
| Ownership | A generic extension's logic stays inside the vendor's own platform | An agency's ownership terms vary by contract | Ours ships as production code in your own repository |
| Delivery | A generic extension installs in minutes but does not know your workflow | An agency usually takes several weeks, set per project | Ours has a fixed delivery time shown before you buy, with faster options |
| Testing | A generic extension is tested by its vendor, not on your real pages | An agency build depends on what was agreed | Ours ships with automated tests plus 30 manual test scenarios on your pages |
One fixed price covers designing, building and packaging a custom browser extension with up to three features, including automated tests, 30 manual test scenarios on your real target pages and a recorded 60-minute technical handoff. The price is shown before you order, with no separate discovery fee.
Typically $50 to $300 a month for hosting and AI usage on your own cloud account, depending on how many team members use it. A small team using it daily usually sits toward the lower end, billed directly to your own accounts.
Standard, Express and Rush delivery times are shown in the price panel before you order. The schedule runs from a complete intake, so it depends on receiving repository access, target pages and design references within 72 hours of ordering. Late information adds delivery time.
It is built for the browser your team actually uses, agreed during intake, such as Chrome or Edge. Supporting more than one browser or engine is possible but sits outside the base scope, and is quoted as a Change Quote if you need it.
Either, depending on what you choose during intake. Private installation for your own team avoids any store review delay, while store publication needs a developer account and passes through that browser's own review process before it becomes publicly available to install.
Yes. Two rounds of changes are included while your technical contact reviews the extension. After launch, adjustments such as adding a page or changing behavior fit inside the monthly change hours that come with maintenance. That also covers adapting to a page layout change. Bigger changes, like a new feature, go through a Change Quote first.
Yes. Automated tests cover the core AI flows, and 30 manual test scenarios are run directly against the real target pages agreed during intake, not a generic test site. You receive the results before the extension is packaged for install.
Order AI Browser Extension Assistant and the finished extension is ready to install, tested on the pages your team actually uses and delivered as code you own.
