Why courses fall short?

Learners have questions. The moment misses a response.

01

Stuck in the moment

A learner hits a question on slide 14 and the course has nowhere to send it. They search elsewhere, ask a colleague, or quit.

The same questions, again

Your facilitators answer the same twenty questions every cohort, repeating what the material already says.

A handbook nobody reads

The answer exists. It just isn’t where the learner is when they need it.

Searching…Where is the answer?

What kind of chatbot do you want to create?

Pick the style that fits the job. You can set its name, voice and look afterwards. This choice decides how it answers.

For your learners

Ask by typing, or just say it.

Learners can type a question or speak it, and hear the answer read aloud in one of four voices. A glowing orb shows when the bot is listening, thinking and speaking, so there’s never any doubt about what it’s doing.

Shape the experience

Your chatbot should feel like yours.

Give every chatbot its own identity and make the interaction feel appropriate for the people who will use it.

For course owners

You stay in charge of what it says, and what it costs.

Know how it is used, fix what the bot can’t answer, and cap what you spend.

See how it is used

Results show answers given, voice used and tokens spent. A list of unanswered questions shows exactly what to add next.

Budget

Cap the cost

Set a token budget and a daily limit for each bot. When the budget runs out, the bot tells learners it’s unavailable and nothing else is charged.

Choose what learners can do

Decide whether learners can send their own files and pictures, or only chat.

Bring your own AI key

Add your Gemini, OpenAI or Anthropic key and answers cost no tokens. Your key is checked on save, stored encrypted, and shown again only after you re-enter your password.

Pull it back instantly

Switch any bot off whenever you need to, for example between cohorts.

You’re never lost

A short tour, a four-step checklist on every bot, and a screenshot guide for computer and phone.

Most bots are better in week two than week one, because the unanswered-questions list tells you what to teach next.

Pricing

Start free. Pay only for the answers your learners use.

One subscription covers every LND builder. Plans decide how many bots and how much knowledge you can keep. Tokens pay for what learners do with them. Teams can ask for Enterprise.

A token is the one unit of use: a typed answer costs about 1.1K, and voice, files and teaching cost more.

How usage is counted

~1.1Kan answer (typical: about 2,000 characters read, 600 written)
~4.6Kan answer about an attached file (12,000 characters)
60Kvoice in: every 15 seconds of speech

300voice out, HD: every character spoken

With your own AI key, answers cost no tokens.

Four voices

Pick the one that sounds right.

Press play. These are real samples of the voices your bot can speak with, and the orb ripples to each one.

Voices are Google's, in two quality levels: Standard (160 tokens per character spoken) and HD (300). Listening to a visitor costs 60K tokens for every 15 seconds of speech.

Questions

Good to know.

How do shared bots work?

Create a free account, make a bot, teach it your documents or web pages, and share its link. Visitors chat with it without an account, and your tokens pay for what they do. See the step-by-step guide.

Who pays when someone uses my shared bot?

You do, with tokens, up to the budget you set for that bot. When it is used up the bot tells visitors it is unavailable, and nothing else is charged. If you add your own AI key, answers cost no tokens and the AI provider bills you directly.

What can I teach a bot?

PDF, Word (.docx), text, Markdown, CSV and HTML files up to 3 MB each, public web pages (and, if you choose, pages they link to on the same site), pasted text, and lists of questions and answers.

Can the bot get things wrong?

Yes, like any AI. An information bot answers only from what you taught it and says so when it cannot find the answer, and it shows which sources it used so people can check. Keep your knowledge up to date, and use the list of unanswered questions to see what is missing.

Is it free to try?

Yes, for 3 days. The free plan gives you every builder with limits: one shared bot, five knowledge sources and 4M starter tokens. It has no backups, and your work is not kept after the trial unless you upgrade to Pro or Lifetime before it ends.

What does the subscription include?

One plan covers all four LND builders: LND Aura (chatbots), LND Infinity (courses), LND SimLab (scenarios) and LND Motion (interactive motion graphics in JavaScript). The free 3-day trial, Pro and Lifetime all give access to every one of them.

What is the difference between monthly, yearly and lifetime?

Monthly is $49 a month. Yearly is $489 a year, which saves you $99 compared with paying monthly, about 2 months free. Lifetime is a single payment of $999 and is limited to the first 100 customers. Pro and Lifetime include the same features, and both include backups.

What is Enterprise?

A custom plan for teams that want every LND builder under one agreement: tokens sized to your team, as many bots and as much knowledge as you need, your own look and web address, invoice billing and priority support. Get in touch and we will set it up with you.

When does the lifetime plan start?

Only when you choose it. It is never added to an account automatically, and it closes once the first 100 customers have taken it.

Who can see my visitors’ chats?

You stay in charge of your bots and what they say. Visitors’ chats are visible to you as the course owner, so you can see what learners ask and what to teach next.

Can visitors send pictures or files?

Only if you allow it in the bot's settings. When they do, the bot can read text in a screenshot, explain a chart or describe a photo. It is good at reading and describing, and can miscount small details. An answer about a file costs about 4,600 tokens.

Which languages does it speak?

English today. More languages are possible later, since the voices and the AI support many.

Can people use my bot on a phone?

Yes. The shared page and the floating window both fit a phone screen, and you can manage your bots from a phone too.

Can I get a branded version for my team or institute?

The name, voice, look (light or dark, in one of four colours) and welcome message are all settings. For a fully branded version, get in touch with LearnNDev.
