Every paid plan includes three core models in full — ChatGPT, Google AI Overviews, and Perplexity. Model add-ons let you extend that coverage with Gemini, Microsoft Copilot, or Google AI Mode, each sold individually as a per-model monthly add-on.
Pricing by tier
| Plan | Per model / month | Per model / month, billed annually |
|---|---|---|
| Lite | $7 | $6 |
| Starter | $25 | $21 |
| Pro | $59 | $49 |
| Advanced | $115 | $99 |
Every add-on model costs the same at a given tier. The price scales with your plan’s prompt volume because an add-on does real work: it runs against every prompt on your plan, every day — 20 prompts on Lite, 350 on Advanced.
Activation
Add-ons apply plan-wide and take effect immediately. The moment you activate one, the new model runs against all prompts in all workspaces on your normal refresh cycle — mentions, rank, sentiment, and source citations tracked from day one. There’s nothing to configure per workspace, and add-on results appear in the same dashboards, filters, and email reports as your core models. See how model selection works for details.
Stacking
Add any combination — one model, two, or all three. Pricing is linear: each add-on costs the same per-model price for your tier, with no bundle mechanics to decode.
Annual billing
Add-ons follow your plan’s billing: on annual plans they get the same ~15% discount as the base tiers ($6 / $21 / $49 / $99 per model per month, billed annually). Full prices on the pricing page.
Cancelling an add-on
You can remove an add-on at any time. On monthly billing it stops right away and the unused portion of the month is refunded automatically through Stripe; on annual billing it keeps running until the end of your paid term. Either way, the historical data it collected stays in your workspace. Full policy in cancellations & refunds.
Enterprise
Enterprise plans include every model BrandAxis tracks — the core three, all three add-on models, plus Claude and Grok — with no add-on charges. Claude and Grok are Enterprise-only. Talk to sales if you need them.
