Simple pricing for individuals, classrooms, schools, and museums

Yes. The Explore plan is free forever, with 20 messages a month with the free library's figures, and no credit card is needed. When you need more, Plus is US$14.99 a month, or US$129 a year, per person, and schools can request a volume quote.

20 messages a month with the free library's figures. The free library is every figure without a lock at portal.humy.ai, which you can browse before you sign up. Figures other teachers share in the Community library, and up to 3 of your own, are free too. It also includes auto-graded assignments in five formats (interviews, debates, simulations, essays and short questions), aligned to AP, Common Core, IB, TEKS and 8 more standards, or to rubrics you upload; graded work that exports to PDF or DOCX with the full conversation transcript; panels of up to 10 figures in one chat, moderated by your students; the Community library of figures, sources, assignments and collections other teachers share; and 90+ AI teaching tools, including Lesson Planner, Quiz Generator and Reading Level Adjuster. You can sign in with your Google or Microsoft account. The limits: one account (students join free through a class link), 3 custom figures, 3 assignments and 3 collections, and your conversation log opens the first 3 student conversations.

Plus is US$14.99 a month, or US$129 a year, per person; paying yearly saves US$50.88 (28%) against twelve monthly payments. Plus includes 2,000 credits a month (24,000 a year if you pay yearly): up to 4,000 messages a month with the default AI model. Other models and voice calls use more credits. It unlocks all 100,000+ figures in the Humy library, including scientists, authors and native speakers for classes beyond social studies, with enough credits for live voice calls. You can read every student conversation in your conversation log, build up to 50 custom figures from documents you upload, and keep up to 50 assignments and 50 collections. Colleagues can join your workspace at the same price per person, up to 15 licenses self-serve, and Plus includes a 30-minute onboarding call with a Humy specialist.

Everything in Plus for every teacher, plus volume discounts and a dedicated account manager. They are student-safe by design: FERPA- and COPPA-aligned DPAs signed in 16 states, and student data is never used to train AI or for ads. An IT approval packet, DPAs and vendor paperwork are ready to forward, and most schools are up and running within days. Teachers sign in with Google or Microsoft (school SSO on request), and students never need accounts. You get usage reporting and conversation oversight across your organization, custom figures built from your own archives with quotations checked word-for-word against the original documents, and deployment on the web or via QR codes, kiosks, embeds and the API, in 50+ languages. Schools and universities can pay by invoice, by bank transfer or card, with VAT handled; in the US we also accept purchase orders and checks and can provide a W-9. Every quote comes with a pilot plan. We built the AI Hatshepsut experience for South Florida PBS; ask about museum pilots.

The chat simply pauses until your messages refill the next month — nothing is deleted, and students keep their conversation history. If you keep running out, Plus has far more. Plus includes 2,000 credits a month (24,000 a year if you pay yearly): up to 4,000 messages a month with the default AI model. Other models and voice calls use more credits.

Prices are in US dollars. Checkout shows the price in your local currency where available; VAT or GST is added where it applies. You can also add a VAT or tax ID at checkout.

Yes, and it's common. Schools and universities can pay by invoice, by bank transfer or card, with VAT handled; in the US we also accept purchase orders and checks and can provide a W-9. We'll also complete vendor-registration paperwork for your school or district. Email hello@humy.ai and we'll sort it out directly with your school office.

Plus renews automatically every month or year until you cancel, and under our Terms of Service payments are non-refundable except where Humy decides otherwise. Paying monthly is the smallest commitment: US$14.99, and you can cancel before the next month starts.

Adults, and minors with a parent's or legal guardian's permission, as our Terms of Service set out.

To cancel, open Billing in Humy and choose Manage subscription; you keep Plus until the end of the period you have paid for. Your account then moves back to the free Explore plan. Changes are self-serve too: upgrades take effect immediately with prorated billing, and downgrades at the end of your billing period.

No. Students join by link with a first name and last initial, with no email and no account. Before their first message, every student sees a short “How to use AI responsibly” notice that names the AI model behind the figure.

Never. Neither Humy nor its technology providers use student messages to train AI models or for advertising. Student data is stored in the US for US schools (EU for others), and Humy has signed FERPA- and COPPA-aligned student data privacy agreements covering 16 states.

General chatbots invent quotes, push upsells, and give teachers no visibility into what students do. Humy is purpose-built for the classroom: figures are grounded in curated sources, and when a figure has a primary-source archive, each quotation is automatically checked word-for-word against the digitized original before students see it. You can also read what your students wrote: the first 3 conversations in your conversation log on Explore, and every one on Plus.

Humy supports models from OpenAI, Anthropic, and Google: GPT-6 Luna, GPT-6 Sol, GPT-6 Astra, GPT-OSS 120B, Claude Sonnet 5, Claude Opus 5.5, Gemini 3.8 Flash, Gemini 3.1 Pro, and Gemini 3.5 Flash Lite for chat, and Gemini 3.8 Live for AI voice calls. For every figure you share, you choose which models students can use and which is the default — faster, lighter models draw fewer of your messages, so you can put a quick model in front of a large class and keep a deeper one for research work. Every figure names the exact model it is using to students before the first message.

Yes. Every figure that answers uses one message from your pool, so a question three figures answer costs about three messages. When the figures discuss a point among themselves, each line counts the same way, and the discussion stops at the limit you set (20 lines at most). Panels are on every plan, including Explore.

Yes. On every plan you can use the figures, sources, assignments, and collections other teachers share, and share your own. Chats with a shared figure draw on your message pool like any other conversation.

Explore includes the free library's figures. The free library is every figure without a lock at portal.humy.ai, which you can browse before you sign up. Figures other teachers share in the Community library, and up to 3 of your own, are free too. Plus unlocks all 100,000+ figures in the Humy library. School and organization plans include the same full library for every teacher.

Explore and Plus are single-person licenses, but you can add colleagues to a shared workspace at the same price per person (US$14.99 a month, or US$129 a year each) — up to 15 licenses self-serve. For a department or a whole school, request a quote and volume discounts apply.

Most schools start with one teacher's free classroom, then bring results to their admin. We'll help: email hello@humy.ai for an IT approval packet, signed student data privacy agreements, vendor registration, and a quote your business office can act on. School plans start at US$600 per school, per year.

Humy is a web-based learning platform — the successor to Hello History — where students interview 100,000+ AI historical figures grounded in curated primary sources and scholarly references. Figures cite the record, and citations link back to original historical sources.
