What counts as an answer?
An answer is one reply a bot writes on tufu's AI, in any channel: a chat bubble on your site, an Ask console in your docs, a WordPress plugin, email, Slack and Discord. A reply on Claude Haiku 5.5 with reasoning off is one answer. On Team, a bot can run on Claude Sonnet 5.5 or Claude Opus 5.5, or reason more, and each reply then counts a set number of answers, shown wherever you choose. Repeat Ask questions served from the cache, suggested replies, summaries and chat titles are free. On Team, answers on your own AI key are free and unlimited.
On Free, answers on your own AI key have their own allowance, 1,000 a month, separate from the ones on our AI. A support conversation takes a few answers: on Claude Haiku 5.5, Team's 4,000 answers are about 1,000 conversations.
What happens when we run out of answers?
Nothing is billed after the fact. Bots on our AI stop answering until next month or the next pack. If your bot offers “Talk to a human”, visitors can still reach your team, and repeat Ask questions are still answered from the cache. On Free, answers start again next month. On Team, add an answer pack or switch a bot to your own AI key. We email your admins at 80% and again when they're used up.
What if we need more answers?
On Team, buy answer packs whenever you like, from $0.005 an answer in the biggest pack. Or turn on auto-recharge: when fewer than 400 answers are left, tufu buys the pack you chose with your saved card, never more than the monthly limit you set, and emails a receipt. Packs are paid up front and never expire, so there's no bill after the fact.
Can we use our own AI key?
Yes, on either plan. Add a key from OpenAI, Anthropic, Google Gemini, xAI or OpenRouter and pick the model; you pay the provider directly. On Team, answers on your key are free and unlimited. On Free, you get 1,000 a month on your key, on top of the ones on our AI.
Why no seats?
On a small team, support is everyone's side job. Invite everyone who helps: the price is for the team, so adding a teammate never costs more.
Will the price change?
$49 a month, or $490 a year, is our early access price. A team that subscribes now keeps it for as long as it stays subscribed. The price for new teams goes up after early access. A new price only ever applies to new subscriptions.
Which AI answers for us?
Our AI runs on Anthropic's Claude, through a commercial API that doesn't train on your data, and your knowledge is searched with a dedicated retrieval model, under terms and settings that keep it from training on your data. On either plan you can choose any model from OpenAI, Anthropic, Google Gemini, xAI or OpenRouter with your own key.
Which models can tufu use?
On Free, bots answer with Claude Haiku 5.5, reasoning off: one answer a reply. On Team, each bot can use Claude Haiku 5.5, Claude Sonnet 5.5 and Claude Opus 5.5, with reasoning off, low, medium or high. A stronger model or more reasoning costs more to run, so a reply counts more answers. The number comes from the model's price, and the bot's settings show it next to every choice:
Answers one reply counts on tufu's AI, by model and reasoning
| Model | Off | Low | Medium | High |
| Claude Haiku 5.5 | 1 | 2 | 3 | 6 |
| Claude Sonnet 5.5 | 20 | 28 | 51 | 111 |
| Claude Opus 5.5 | 56 | 56 | 101 | 222 |
Claude Opus 5.5 always reasons a little: off counts and runs as low.
On either plan, a bot on your own AI key can use any model from OpenAI, Anthropic, Google Gemini, xAI or OpenRouter, at any reasoning level the provider takes, and its replies aren't counted.
Do you train AI on our data?
No. Your docs and your visitors' conversations are used only to answer for you. See our Privacy Policy.
Where does our data live?
Your account, bots, knowledge and conversations are kept in a database hosted in the United States, and uploaded files are stored with Cloudflare. Every provider that handles your data, and where, is on our Subprocessors page. More in our Privacy Policy.
Are there other limits?
A few safety limits stop one visitor, a script or a runaway bot from using up your answers in an afternoon. Normal traffic never comes close, and a visitor who reaches one is offered a person. The numbers are in the docs.
Can we cancel anytime?
Yes. Your plan runs to the end of the period you paid for, and you can export your conversations first.
