Plans, billing and credits

Every site starts on Free, and you pay for Pro per site. AI credits pay only for work Lentil's own AI does, never for editing, publishing or hosting. This page covers what each plan includes, how to upgrade, and how credits work. Prices are in US dollars.

Free and Pro

The plan belongs to a site, not to your account. One workspace can hold Free sites and Pro sites side by side.

Everything else is on every plan: fast hosting with HTTPS, drafts and version history, one-click rollback, the inbox, weekly site checks, Google Business Profile and Search Console, and using Lentil from ChatGPT, Claude or another assistant. These figures are the same as on the pricing page.

More sites, less per site

Every Pro site in a workspace is billed at the price for the workspace's total number of paid Pro sites. When you add a site that reaches the next step, all your Pro sites drop to the lower price.

Yearly billing is two months free compared with paying monthly. The Billing screen shows these steps with your current one highlighted, and tells you how many more Pro sites it takes to reach the next price.

Upgrade a site to Pro

You upgrade one site at a time, from that site's settings or from the workspace's Billing screen.

The first Pro site in a workspace

1. Open the site, choose Settings in the sidebar, then the Plan section.
2. Under Billing interval, choose Monthly or Annual. The line next to it shows the starting price per site.
3. Press Upgrade to Pro. Lentil opens a secure Stripe Checkout page.
4. Pay there. You come back to the Plan section with a message: Payment received. This site is Pro now.

If the site was made from a free sample, Lentil then builds the rest of its planned pages at no credit cost and says so in the same message.

More Pro sites after the first

1. Open the same Plan section on the next site and press Upgrade to Pro. Your workspace already has a subscription, so there is no new checkout and the interval follows the subscription.
2. A dialog titled Upgrade to Pro shows the exact amount. It says how much is charged now for the rest of the current period, and what your Pro sites cost at each renewal after that.
3. Press Pay $X and upgrade (with the real amount on the button). Nothing is charged before this.

If the subscription has an unused Pro seat, for example because another site was switched to Free, the dialog says the site takes that seat at no extra charge and the button reads Upgrade. If the price moved while the dialog was open, you see a notice and the new amount to confirm instead.

Upgrade Rosa's Bakery to Pro on the annual plan. Show me the price or the Stripe link first and do not charge anything until I say yes.

Switch back to Free or keep Pro

A Pro site you pay for has a Switch to Free button in its Plan section.

1. Press Switch to Free. The dialog Switch to Free? explains what happens.
2. Press Switch to Free again to confirm, or Cancel.
3. The section now says Pro until the end of the period you already paid for, then Free.

The site stays Pro until that date. After it, everything the site already has keeps working: its pages, domain, forms and languages stay as they are. Only new pages, uploads, domains, forms and languages follow the Free limits. There is no refund for the current period.

Changed your mind before the date? Press Keep Pro in the same section. The dialog Keep Pro confirms the site stays Pro and that nothing is charged now.

The Billing screen

Open Billing in the workspace sidebar. It has these parts:

• Plan: how many Pro sites you have, how many are active, ending or unused, what each costs, and when the subscription renews (or ends). The price steps are shown with yours highlighted.
• AI credits: your balance, split into Monthly and Extra, and the date the monthly credits reset.
• Sites: every site with its plan, host name and price, with Upgrade or Plan settings.
• Buy credits: the credit packs (see Buy more credits).
• Usage history: where credits came from and where they went (see Usage history).
• Invoices and payment method, at the top: opens the Stripe billing portal, where you see invoices, change the card, and cancel or resume the subscription. It shows once the workspace has a billing account, which the first purchase creates.

What uses AI credits

Credits pay for work that Lentil's own AI does on its servers. One credit is worth one US cent of the AI provider's cost. You always see the estimated cost before Lentil starts a bigger job, such as building your pages.

Your usage history labels the free items with (included), for example Homepage designs (included) and Build plan (included).

How much you need to start

Before Lentil's AI starts an action, the workspace must have at least this many credits free. This is a safety minimum, not the price: most actions cost less, and you are charged what the AI really used.

How many AI credits does my Rosa's Bakery workspace have left, when do the monthly credits reset, and what used the most credits this month?

Your credit balance

Credits belong to the workspace and are shared by every site in it. The balance is on the AI credits card at the bottom of the sidebar and on Billing. It has two parts:

• Monthly: Each Pro site adds 500 credits a month. The monthly credits are used first. They reset on the date shown, and what you did not use does not roll over.
• Extra: Credits from packs and credits added by the Lentil team. They never expire, and are used after the monthly ones.

The monthly period starts the first time your workspace has a Pro site and then repeats every calendar month from that day, whether you pay monthly or yearly. A site that becomes Pro in the middle of a period adds its share of the rest of that period straight away.

While Lentil's AI is working, the credits it may need are held for that job and show as spoken for, so two jobs cannot spend the same credits. If a new job is refused for that reason, wait for the running one to finish.

When the balance drops below 50, Billing shows a warning with a Buy credits button. When it reaches 0, Lentil's AI pauses until credits are added. Editing, publishing and hosting keep working.

Buy more credits

1. Open Billing and find the Buy credits card. You can also press Buy credits next to AI credits, or Buy more on the sidebar's credits card.
2. Choose a pack: 500 credits for $15, 1,500 credits for $35 or 5,000 credits for $99.
3. Press the button, for example Buy 1,500 credits for $35. You pay on a secure Stripe page.
4. Back on Billing, a message says how many credits were added to the workspace.

If your bank is still confirming the payment, the message says it is processing and the credits arrive as soon as it clears. If you close the checkout without paying, you are not charged.

We are almost out of AI credits. Give me the link to buy the 1,500 credit pack for the Rosa's Bakery workspace.

Usage history

The Usage history card at the bottom of Billing lists every change to the balance, newest first. Use All, Used or Added to filter, and Show older to load more.

Each row shows when it happened, what it was, the site if there is one, and the credits, with + for credits added. AI work is grouped per job, so one editor turn or one build is one row, named for example Editor AI, Canvas AI, Generated image, Translation or Fix with AI. Other rows are Monthly credits, Unused monthly credits expired, Credit pack, Credit pack refunded or disputed, Credits added by the team and Build capped at its estimate.

When a payment fails

• The last payment failed. The Plan card says so next to the renewal date. Open Invoices and payment method and update the card. Only an owner can do this.
• The subscription is unpaid or paused. A notice on the Plan card says which, and that your Pro sites come back automatically once the owner pays the outstanding invoice or resumes the subscription in the billing portal. Until then Lentil does not offer new upgrades.
• A card payment is declined while upgrading. The dialog says the payment did not go through. Update the payment method, then start the upgrade again to get a fresh price.
• The subscription is set to end. You cannot add Pro sites to it until you resume it in the billing portal.
• A credit pack is refunded or disputed. Its credits are taken back and shown in your history. If they were already used, the balance can go negative until new credits arrive.

Who can use it

Roles are explained in Team and roles.

Limits and edge cases

• Free sites: 5 pages, 500 MB of media, 1 contact form live at a time and no custom domain. Pro: unlimited pages and forms, 5 GB, and up to 3 extra languages.
• When a site goes back to Free it keeps everything it has, including domains and languages that are already there. Only adding more follows the Free limits.
• A Free site's second contact form cannot be published: publish the page that already has your form first, or upgrade.
• Media warns Storage almost full from 90% of the limit. At the limit, uploads are refused until you delete files or upgrade.
• If a payment for a Pro site goes through but the site is not Pro yet, it completes by itself within a moment. If it does not, confirm the upgrade again at no extra charge.
• Only one billing change per workspace runs at a time. If you see that another change is in progress, try again in a few seconds.
• Pack credits never expire. Unused monthly credits expire at the reset.

From an AI assistant

An assistant connected to Lentil works as you, with your role in each workspace. See AI assistants to connect one.

• get_site_plan: a site's plan, what it includes and how much of each limit it uses.
• get_credits: the workspace balance (monthly, extra and total), the reset date, and whether credits are being enforced. Clients get no balance.
• get_credit_history: the usage history, newest first. Owners and admins.
• get_billing: the subscription, Pro sites, seats and credit packs. Owners and admins.
• upgrade_site and downgrade_site: change a site's plan. Owners and admins; only an owner can start the first subscription.
• buy_credits, open_billing_portal and get_checkout_status: owners only.

Safety rules: an assistant never takes a payment itself. For a first Pro site or a credit pack it gives you a Stripe link to open. For a later Pro site, upgrade_site first returns a quote and charges nothing; the assistant must show you the amount and call again with confirmed: true (and the quote's values) only after you agree. If the price changed, it asks for a new quote. downgrade_site also needs confirmed: true after you agree.
