25 free voice minutes — real, telephony-grade calls, telephony included — on curated free models (Prana LLM plus gpt-4o-mini), plus 200 free chat replies. Premium LLMs (Claude, Gemini, GPT-4o full, GPT-5) are PAYG-only. Bringing your own number is fully open on Trial. No card required.

Voice agents stop placing/answering calls until you top up or subscribe. Topping up moves you to Pay As You Go automatically — no contract, no monthly fee. Your existing agents, flows, and integrations carry over instantly. Trial-only model gating lifts the moment you leave Trial.

Pay As You Go has zero monthly fee — you pay a flat ₹2/min for voice calls on standard voices, or ₹2.5/min on premium voices, telephony included either way. Calls are metered in 30-second pulses, not rounded up to the next whole minute. Chat replies are usage-based, never a flat quoted rate. Prefer predictable billing? Pro is ₹2,499/mo and Scale is ₹4,999/mo — each subscription hands its own fee straight back as usage credit, spent before your own top-up money, so most months the plan pays for itself in what it lets you use. Scale also takes 5% off every voice minute once you go past the credit. INR via Razorpay/UPI, GST invoices on every transaction.

Standard voices are ₹2/min, premium ₹2.5/min, and Studio Voices ₹3/min — ₹1.90 / ₹2.375 / ₹2.85 on Scale, which takes 5% off all three. All three rates are flat and all-inclusive — telephony is in the price, there is no per-language surcharge, and nothing else is metered on top of the minute. Premium voices are our most lifelike stock voices. Studio Voices go a step further: pick a curated studio voice or clone your own (up to 10 on Pro, 20 on Scale), on Pro and above. You pick per agent, so you are never moved onto a higher rate without choosing it — most agents run happily on standard voices. Ear mode — real-time speech recognition, so callers can cut your agent off mid-sentence and it knows sooner when they have finished — comes at no extra charge: you pay the rate of the voice.

Find Leads — describe the businesses you want and get their phone numbers and emails — gives you 50 free leads in your workspace's first month. After that it is ₹1 for each lead, from your balance, and you only pay for leads that come back with a phone number or an email. Businesses with no contact details, ones that are not a match and ones you already have are never charged. There is no subscription and no seat fee. The free Trial needs a paid plan once its 50 free leads are used.

In 30-second pulses, from the moment the call connects. A 40-second call bills as 60 seconds, not as two whole minutes. Plenty of platforms round every call up to the next full minute, which quietly adds 20–40% to a bill made of short calls — collections reminders and delivery confirmations especially.

Separately from phone calls, and it is worth keeping the two apart. Chat replies are usage-based — the Trial includes 200 free, and there is no monthly fee on Pay As You Go. WhatsApp calls are billed at your voice rate, by the whole minute rather than in 30-second pulses, with nothing of Meta’s added — Meta charges nothing for calls your customers start. Meta charges separately, per message, at rates it publishes and changes itself — in India ₹0.8631 for marketing and ₹0.1150 for utility or authentication, before 18% GST. Meta bills that to the payment method on your own Meta account — add one in Meta’s Billing & payments when you connect — and we add a 10% platform fee per message, from your balance here. Since 1 October 2026, Meta also charges for replies you send inside a customer’s 24-hour window, at the utility rate. Using only the WhatsApp API from your own software, with no agent of ours? There is no monthly fee, and the Trial includes 200 WhatsApp messages, one time, with none of our charges. More on the WhatsApp Business API.

Pro is ₹2,499/month (₹29,988 billed yearly — no discount for paying annually, you simply get the year's credit up front). It grants ₹2,499 of usage credit every month, spent before your own balance, and adds Studio Voices at ₹3/min, cloning up to 10 voices, 5 agents across 2 workspaces with 2 team members, 10 concurrent voice calls, a widget without our branding, reselling to up to 20 clients under your own brand, and 49-day call recordings. It's the tier most teams should be on.

Scale is ₹4,999/month (₹59,988 billed yearly — same reason as Pro, no discount, just the credit up front) on top of the same usage-based rates as Pay As You Go. It grants ₹4,999 of usage credit every month, and adds team workspaces (100 organizations, 5 seats), 15 concurrent voice calls instead of Pro's 10 (more on request), 5% off every voice minute, cloning up to 20 voices, reselling to up to 100 clients under your own brand, and priority support. Subscribe from Settings → Billing, just like Pro.

A negotiated contract: custom volume, concurrency and cloned-voice limits, dedicated capacity, SSO/SAML and audit logs, an uptime commitment, and a dedicated point of contact. Pricing and limits are worked out with our team rather than posted here — write to hello@thinnest.ai.

Yes — on every paid plan. White label lets you sell to your own clients under your name, logo and domain: up to 3 clients on Pay As You Go, 20 on Pro and 100 on Scale (more on Enterprise). Each client gets its own workspace, its own plan and a free trial you size; you set your own prices — a percentage on top of our usage rates, and an amount on top of Pro and Scale — and your clients pay you through your own Razorpay. We charge you our prices for what they use, so the difference is yours. There is no extra fee for white label itself.

Yes, from Settings → Billing. Trial → Pay As You Go happens automatically the moment you top up. Pay As You Go can subscribe to Pro or Scale directly. Moving from a paid subscription back to Pay As You Go takes effect immediately and your balance keeps working; moving between Pro and Scale needs the current one to end first — cancel it, keep access until the period you already paid for runs out, then subscribe to the other. Enterprise is a sales conversation in both directions — write to hello@thinnest.ai.

Only payment gateway charges, passed on at cost: 2.36% on rupee payments (Razorpay's 2% plus 18% GST on it) and 4% on dollar payments. There is no fee of ours on adding money. The charge is added on top and shown as its own line before you pay, so a ₹1,000 top-up lands as exactly ₹1,000 in your balance and costs ₹1,024.17 (the provider takes its percentage of the whole payment, so the charge is worked out to leave your full amount). Subscriptions carry it the same way — Scale is ₹4,999 + ₹120.83 a month, and its usage credit is the full ₹4,999. UPI and most methods cost 2.36%; some cards cost more, and the exact line is shown before you pay.

Yes — Razorpay handles all Indian methods (UPI, net banking, RuPay/Visa/Mastercard cards, wallets). Enterprise customers can pay via bank transfer / NEFT / RTGS with GST invoices. We don't accept crypto.

Yes — that's the Trial plan above. Sign up with email or Google, get 25 voice minutes immediately. No card, no commitment, Plivo, Vobiz, Twilio and Telnyx number import unlocked, all 22 scheduled Indian languages and English.

We publish honest head-to-head comparisons with every major voice AI platform. See all 15 comparisons — each one breaks down real pricing math, feature matrices, and the cases where the competitor is actually the better pick.

No. You can buy an Indian phone number directly from us in a click — ₹349/mo on Pay As You Go, ₹249/mo on Pro and Scale — we provision and configure it for you (including TRAI 140-series). Or import a number you already have with Plivo, Vobiz, Twilio or Telnyx: you keep paying your carrier directly, and we charge ₹0 for it.

Workspace caps are smaller (1 agent vs PAYG's 2) and concurrent calls are capped at 1 vs PAYG's 5. Otherwise the platform is the same — same flow editor, same telephony, same Indian-language coverage, same SDKs and webhooks.
