WebWorks Platform · Pricing

Start free. Pay only for smarter answers.

Three plans for the AI Assistant, on your website and in your published help. Every plan falls back to the free model when paid usage runs out — never a surprise bill, and your Assistant keeps answering within fair-use limits.

Buy Pro or Enterprise on your ePublisher order or renewal: one order, a fixed annual price. How it works

The plans

Three plans, one free model.

Build and test unlimited Assistants on every plan. Budgets, spend caps, and auto top-up are yours on every plan. What the plans change is how many Assistants can be live, how much AI usage and Knowledge storage is included, and whether the chat carries a WebWorks badge.

Both billing intervals are self-service from day one, and the annual rate is the lower of the two. All pricing is introductory.

Buy it with ePublisher

Buy it on your ePublisher renewal: one order, a fixed annual price.

Pro and Enterprise can go on a quote, purchase order, and invoice, on their own or on the same order as your ePublisher purchase or renewal. Your order comes with a plan code. Redeem it on your Platform billing page and your organization is on the plan for a year, with no card on file. The cost is the annual plan price, and usage beyond the monthly allowance keeps answering on the free model, so there is no token bill to forecast.

Per question

What a question costs.

Two numbers, the same on every plan — a Pay-As-You-Go question and an Enterprise question cost the same.

GPT-5.4 Nano Free the free model, always included on every plan

GPT-5.4 Mini ~5¢ per typical question at default settings

Four things move the cost of an answer: the model, the reasoning effort, how much of your Knowledge Base the answer reads, and the length of your instructions.

Preview shows the exact cost of your configuration before you go live. Run the questions your readers actually ask, against your own Knowledge Base, and read the price of each answer before an Assistant goes In Deployment.

No surprises

What happens when…

Paid usage runs out: The Assistant keeps answering on the free model. Add usage any time — buy credits once, or let auto top-up do it for you.
I set a daily budget: Budgets are per Assistant and set in dollars. At the cap, the Assistant keeps answering on the free model — or pauses until the next day, if you prefer.
I never add a card: Pay-As-You-Go stays free on the free model. A paid plan costs exactly the plan price.
I have a fixed annual budget: Pick Pro or Enterprise and leave auto top-up off, or buy the plan on your ePublisher order. Either way the cost is exactly the plan price, and usage beyond the allowance continues on the free model.

Fine print

How the numbers work.

A typical question: The ~5¢ used throughout the plan comparison is a typical grounded question on GPT-5.4 Mini at default settings, and the rate is the same on every plan. A free-model answer costs nothing on any plan. Preview shows what your own configuration costs.
Allowances reset monthly: Included usage resets at the start of each monthly period and does not carry over. The allowance is the same on either billing interval. Question counts beside an allowance are estimates on GPT-5.4 Mini, not entitlements.
Launch credit: Pay-As-You-Go includes a one-time $5 launch credit to try smart models live. When it is spent, the Assistant continues on the free model; buy credits any time to keep smart models on.
Knowledge storage: Every plan includes a Knowledge Base storage cap — 100 MB on Pay-As-You-Go, 1 GB on Pro, 5 GB on Enterprise. Storage never counts against your usage. The cap is the most your Knowledge Bases can hold on the plan; a larger documentation set means a larger plan, not a bill.
Cost controls: Budgets, spend caps, and auto top-up are on every plan, including Pay-As-You-Go. A daily budget is per Assistant and set in dollars. When an Assistant reaches it, it keeps answering on the free model — or pauses until the next day, if you prefer — and you get an email either way.
Fair use: Free-model answers carry fair-use limits — a per-visitor limit and a daily ceiling per organization — and those are hard stops: past them, public chat pauses until the limit resets.
All pricing is introductory: Plan prices, included usage, storage caps, and per-question figures are introductory and reviewed on a regular cadence.

With or without ePublisher

One set of plans, wherever it runs.

The plans cover the AI Assistant wherever you install it. On any website it takes one line of script and answers from the pages Platform imports from your site, with no ePublisher involved.

In Reverb 2.0 help, ePublisher 2026.1 produces both halves from your target: turn on Generate Knowledge Base and every build emits the AI-ready Knowledge Base archive, and turn on Generate Assistant to put the Assistant in the published help. WebWorks Platform is a separate subscription from ePublisher, but you can buy both on one order: put Pro or Enterprise on your ePublisher quote or renewal.

Where each Assistant fits

Get started

Start free, then pick the plan that fits.

Pay-As-You-Go is free with no card required, and includes a $5 launch credit to try smart models live. Build and test as many Assistants as you like before anything goes In Deployment.
