Plans & Billing

Understanding your subscription plan helps you get the most out of Nexus and choose the right tier for your needs.

How pricing works

Nexus plans are priced by AI conversations per month. A conversation is a unique customer your AI replies to within your monthly billing period — the count renews on your billing date each month, and your paid plan starts with a full allowance (conversations from your free trial are not carried over).

There are two ways to power the AI:

• Managed (default): We provide the AI. You don't need any OpenAI account or key — it just works. Each plan includes a monthly conversation allowance.
• Bring your own key (BYOK), on Growth and Business: Connect your own OpenAI API key and get unlimited conversations and unlimited pictures — at the same plan price. You pay OpenAI directly for usage.

You can switch between the two at any time (see "Using your own OpenAI key" below).

Trial Period

When you first sign up for Nexus, you start with a free 7-day trial. No credit card required. You can try every feature, within these limits:

• 100 AI conversations / month
• 1 messaging channel
• 2 team members
• 10 products in your catalog
• Reads 200 customer pictures / month

The countdown appears in your dashboard so you always know when it expires. When your trial ends, access is paused until you choose a plan — you can pick one and pay on the spot (see "Choosing a Plan and Paying" below). Your data is preserved throughout; paying simply unlocks continued access.

Available Plans

Nexus offers three paid plans plus a custom Enterprise option. Conversation allowances apply to the Managed mode.

Comparing Plans

Pictures your customers send

From Growth up, the assistant reads the pictures customers send (an ad screenshot, a product photo, a receipt, a price list) and answers about them, so the customer does not have to type it all out. Each plan includes a number of pictures a month:

• Growth: Reads 300 customer pictures / month
• Business: Reads 1,500 customer pictures / month

The count renews with your conversations, on your billing date. Your team sees every picture in the inbox, whatever the count. If the month's pictures run out, the assistant keeps replying and tells the customer it cannot see the new picture, and your admins get one notification. With your own OpenAI key, pictures are read with no monthly limit.

Switch it on per channel: open the channel, then Assistant → Image Messages. The same place shows how many pictures were read this month.

Using your own OpenAI key (unlimited)

On Growth and Business, bringing your own key unlocks unlimited conversations and unlimited pictures, at the same price.

To switch to your own key:

1. Go to AI Assistants and open your assistant's settings.
2. Paste your OpenAI API key into the API key field and save. We verify the key before activating it.
3. Once a valid key is set on all your active channels, your account switches to unlimited automatically.

To switch back to Managed: remove the key from your assistant. To avoid any mid-month disruption, your unlimited access continues until the end of the current month, then your plan's monthly conversation allowance applies again.

You can see your current mode and this month's usage anytime under Settings → Organization.

If Your Key Stops Working

Because the key is yours, only you can fix it — so we tell you the moment it becomes a problem. If your OpenAI credits run out or the key is revoked, your assistant stops replying, and your organization's admins get a notification in the app, a push to their phone, and an email naming the actual cause and what to do.

Fix it at OpenAI (add credits, or paste a new key into your assistant's settings) and replies resume on their own — nothing needs restarting. We only alert once the failure is clearly sustained, so a brief traffic spike will not trigger it.

This applies to your own key. If something goes wrong on our side in Managed mode, that's ours to fix and you won't be paged for it.

Add-ons

Growth and Business can add seats and channels without changing plans:

• ⁦+$10⁩/mo per extra member
• ⁦+$10⁩/mo per extra channel

Add them yourself in Settings → Plan & billing. You pay only for the days left in your current period, and the seat or channel opens as soon as your payment is confirmed; from your next renewal it is part of your subscription. Need fewer later? Lower the number on the same page and it takes effect at your next renewal.

Extra Conversations in a Busy Month

On Growth and Business you can top up a month without changing plan:

⁦+$20⁩ for 500 more conversations in a busy month

Buy it from Settings → Plan & billing. The conversations are added when your payment is confirmed and last until your monthly allowance renews.

Paying for a Year

Pay for 12 months and get 2 free: Starter ⁦$490⁩ · Growth ⁦$990⁩ · Business ⁦$1,990⁩ a year. Prepay 6 months or more and we set up and train your assistant for you.

Choose 6 or 12 months when you first pick a plan, or at any time in Settings → Plan & billing. You get one invoice for the whole term; it starts when the period you have already paid for ends, so you never pay twice for the same days.

Choosing a Plan and Paying

When your trial ends, you can pick a plan and pay straight away — no email round-trip. You'll land on a page listing Starter, Growth and Business; choose one and you're taken to a secure payment page.

Moving up (for example Starter to Growth) takes two clicks in Settings → Plan & billing. You get an invoice for the difference between the two plans for this month, and the bigger plan is yours, with its full allowance for the month, as soon as your payment is confirmed. Your renewal date does not change; from it you pay the new price. If you are in a period you paid for up front, the difference is for the rest of that period.

Moving down is done on the same page and takes effect at your next renewal, so you keep everything you paid for until then. If you are using more than the smaller plan allows (channels or team members, for example), the page tells you what to reduce first.

If your subscription was arranged with us directly, write to info@jack-ai.net and we make the change for you.

Only organization admins can choose a plan and pay. If you're a member or viewer, ask an admin to complete it.

How You Can Pay

Pay by card and your subscription renews monthly on its own, or by local transfer with a copy of the receipt. The payment page shows the options available to you.

Card payments activate your plan automatically. A transfer is confirmed by a person on our side, so your plan activates once we've checked the receipt — usually quickly, and you'll get an email the moment it clears. If a receipt can't be confirmed, we email you the reason along with a fresh payment link.

Your payment link is valid for 14 days, and submitting a receipt uses it up — so if you need to pay again, use the new link we send rather than the old one.

What happens to your data: Upgrading preserves all your data, conversations, leads, and team members. Nothing is lost.

Renewals, Late Payments and Suspension

We email your organization's admins at each step, so nothing happens without warning:

1. Renewal reminder — ahead of your subscription renewing.
2. Payment overdue — if a payment doesn't arrive on time, you keep full access during a short grace period while we let you know.
3. Suspended — if that passes with no payment, access is paused. Your data is kept, untouched. Paying restores access immediately.

If you're suspended, you stay signed in and can pay from the notice shown to you.

Frequently Asked Questions

Do I need my own OpenAI key? No. By default we provide the AI (Managed mode) and your plan includes a monthly conversation allowance — most customers never touch an API key. If you want unlimited conversations, you can connect your own OpenAI key on Growth and Business.

What counts as a conversation? A unique customer your AI replies to within your monthly billing period. Multiple replies to the same customer in the same period count as one conversation. The count renews on your billing date — the day your subscription renews, shown next to the counter in your dashboard.

What happens if I reach my monthly conversation limit? On Managed mode, new conversations pause until your allowance renews on your billing date. On Growth and Business your own OpenAI key gives unlimited conversations and restores service right away. Upgrading your plan, or buying a conversation pack, restores it as soon as the payment is confirmed. Conversations already in progress are not cut off.

Can I change plans later? Yes. If you're on a trial, you can choose a plan and pay yourself as soon as the trial ends. On a paid plan you move up or down yourself in Settings → Plan & billing, as described above. If your subscription was arranged with us directly, write to info@jack-ai.net and we make the change.

What happens if I don't pay on time? You keep full access for a short grace period, and we email you about it. If that passes without payment, access is paused — but your data is kept and paying restores it immediately.

What if I need a custom plan? Enterprise customers can work with our team on custom pricing and volume. Email info@jack-ai.net to discuss your needs.
