Give your courses a voice — AI narration and presenters, powered by ElevenLabs

Recording narration is the part of a course everyone postpones. You need a quiet room, a decent microphone, and eleven takes. Then one slide changes next quarter and you do the whole thing again.

Today we are releasing AI narration for video lessons, powered by ElevenLabs. Write the script — or let Konstantly draft it from your slides — pick a voice, and generate. No recording session, and no re-recording when the content moves.

Write, Listen, Then Apply

Open a video lesson and click Generate with AI. The assistant reads the pages you have already built and writes a first-pass script. It is a draft, not a decision — edit it, or ignore it and write your own.

Under the script sits a line telling you how long it is and roughly how much audio that becomes. Then you pick a voice from your ElevenLabs library and press one button.

You hear the result before it touches the lesson. Applying it is a separate, deliberate click. A lesson is never overwritten by something you have not listened to.

What Learners See While It Plays

An audio-only lesson used to show learners nothing at all — a voice from somewhere, a static slide, no sign anything was even running.

Now narration can carry a presenter, and there are two kinds.

A mark in your brand colour. A waveform or a soft pulse, drawn from the narration's own amplitude. When the voice pauses, it goes still. It is not decoration pretending to be in sync; the motion is the audio.

Or a person. Twelve presenters, lip-synced to your narration. They are generated people — not actors, not stock photography, and not anyone real. That matters more than it sounds: a stock model release written before AI animation does not cover making that face say new words, and standard photography licences do not either. A person who does not exist has no likeness to license.

Pick either from the same grid. The mark costs nothing beyond the narration. A person is a video render, and the tile says so before you choose it.

Why It Runs On Your Key

This is the part worth explaining, because it is a choice rather than a limitation.

Text-to-speech is genuinely metered — every character of script costs real money at the vendor. The usual move is to hide that: bundle "AI minutes" into plan tiers, add a margin, cap you when the margin gets uncomfortable, then re-price once you depend on it.

We wired your ElevenLabs account instead.

Your rates. ElevenLabs bills you at whatever your plan there costs. We add no markup and take no cut — the same reasoning as our zero-commission Stripe integration.

Your voices. The list is your own library, not a fixed menu of ours. If you have built a brand voice on ElevenLabs, your courses can speak in it.

Your ceiling. Your ElevenLabs plan is the only ceiling. There is no bundled quota of ours to run into.

And it is honest custody: Konstantly holds no ElevenLabs key of its own in production. If you never add one, the feature simply is not on. There is no shared account quietly paying for everyone until the feature gets popular and has to be re-priced.

One exception runs the other way. Drafting the script costs you nothing extra — that step uses Konstantly's own AI, like the rest of the assistant. Only the voice itself touches your ElevenLabs account.

Guardrails Before Anything Is Spent

An author with a text box and someone else's API key is a budget incident waiting to happen, so the controls came first.

• The feature is off by default and switched on per account.
• Your admin holds the key and the limits: minutes per author per day, minutes per account per day, and a maximum script length — all in Settings → AI.
• The character count and duration estimate sit above the Generate button, which is the only control that spends anything.
• Failures say what actually happened. An ElevenLabs account out of credits and a plan that lacks a capability are different problems with different fixes, and the message tells you which one you have.

Getting Started

1. Get an ElevenLabs API key from your ElevenLabs account.
2. In Konstantly, open Settings → AI → AI Presenter, paste the key, switch it on, and set your daily limits.
3. Open any video lesson and click Generate with AI.

AI narration is available on Business and Enterprise plans. If it is not switched on for your account yet, get in touch.
