The billing page at /app/billing lists every plan, a comparison table, and a short FAQ. This doc reflects what's literally in the three source files that power it.

Page header

• Eyebrow: BILLING

• : Choose a plan that scales with you

• Subtitle: "Every paid plan starts with a 7-day free trial. Cancel anytime, no questions asked."

Top-right buttons:

• See my usage (ghost) → /app/usage
• Manage subscription (outline) — rendered only if subscription is present. Clicking fires router.post("/app/billing/portal").

Current-plan strip

Below the header. Two variants:

Without a subscription (verbatim):

You're on Free. Upgrade anytime for more chatbots, messages, and AI tools.

With a subscription:

Current plan: {currentPlanName}

Additionally:

• If subscription.status === "trialing", a small amber Free trial pill is shown
• If subscription.current_period_end is present, "Renews {Mon D, YYYY}" is appended

The four plans (verified from priv/repo/seeds/plans.exs)

Plan	sort_order	Price (cents)	Interval	Chatbots	Documents	URLs	Messages/mo	Chars trained
Free	0	0	month	1	3	5	50	400,000
Starter	1	2,900	month	3	20	50	2,000	2,000,000
Growth	2	7,900	month	10	100	200	10,000	11,000,000
Business	3	19,900	month	50	200	500	30,000	40,000,000

All four are interval "month". No yearly plans exist in the seed.

The seed comment captures the training-limits philosophy (verbatim):

• max_chars_trained is the PRIMARY / binding constraint (enforced before ingest)
• max_trained_documents / max_trained_urls are loose OPERATIONAL caps only (they protect the Oban queue, PDF/DOCX parser, crawl throughput). The UI de-emphasises these counters in favour of the chars bar.

Plan card copy

Each card shows a one-line pitch (verbatim from PLAN_COPY in Plan/Index.jsx):

• Free — "For kicking the tires. Not for production."
• Starter — "For solo founders adding a chatbot to one site."
• Growth — "For businesses closing leads on autopilot." + Most popular badge
• Business — "For teams with multiple bots and serious volume."

Only Growth has a badge. The card body shows:

• {plan.name}
• Pitch
• Price: "$NN / month" for paid plans, Free for Free
• Bullet list: {max_chatbots} chatbot(s), {max_messages} messages/mo, {max_chars_trained} training chars (formatted with K / M suffixes)
• Plus one bullet per feature enabled on this plan (see below)

Action button on each card

Verified from PlanCard:

• If it's the current plan: a disabled-looking Current plan pill (no action)
• Otherwise a Button whose label depends on state:
  • With an existing subscription, clicking Free: Downgrade
  • With an existing subscription, any other plan: Switch to {plan.name}
  • Without a subscription, and plan.trial_period_days > 0: Start {N}-day trial
  • Without a subscription, Free: Stay on Free
  • Without a subscription, any other paid plan: Start free trial

All buttons fire router.post("/app/billing/checkout", { price_id: plan.stripe_price_id }).

Feature gates (verified from lib/chatbotgen/features.ex)

The @min_sort_order map:

Feature key	Min sort_order	First plan that has it
whatsapp	0	Free
telegram	0	Free
custom_branding	1	Starter
tools	2	Growth
handoff	3	Business
priority_support	3	Business

Each plan's features map is generated by Features.features_for_plan/1 at seed time and re-derived by the JSON serializers at runtime.

Display labels (verbatim from FEATURE_LABELS in Plan/Index.jsx)

• whatsapp → WhatsApp integration
• telegram → Telegram integration
• tools → AI Tools (lead capture, booking, email, webhooks)
• handoff → Human handoff
• custom_branding → Remove ChatbotGen branding
• priority_support → Priority support (24h SLA)

Trust row (3 cards)

Verbatim:

• 7-day free trial — "Every paid plan includes a full week of access — no charge until day 8."
• Cancel anytime — "One click in the customer portal. Keep access through the end of the billing period."
• Upgrade or downgrade — "Change plans mid-cycle with prorated credits. We'll never lock you in."

Comparison table

Heading: Compare every feature. Subtitle: "The honest breakdown. No asterisks."

Rows (in this order):

1. Chatbots
2. Messages / month
3. Training content
4. Documents / bot
5. URLs / bot
6. WhatsApp integration
7. Telegram integration
8. AI Tools (lead capture, booking, email, webhooks)
9. Human handoff
10. Remove ChatbotGen branding
11. Priority support (24h SLA)

Feature cells render ✓ when the plan has the feature, — when it doesn't.

Common questions (FAQ — verbatim)

• What happens if I hit my message limit? — "Your chatbot keeps running but will reply with a friendly 'please try later' message to new visitors until the next billing period — or until you upgrade."
• What counts as a 'training character'? — "Every character of the content you feed your chatbot — URLs crawled, files uploaded, Q&As, and text sources. We measure the raw text, not images or HTML."
• Can I switch plans later? — "Yes. Upgrade instantly (prorated) or downgrade at the end of the cycle. No hidden fees, no contracts."
• Do you offer a free tier? — "Yes — Free forever, 1 chatbot, 50 messages/month, 400K training chars. Great for testing. Production customers typically start on Starter."
