LanglessHow much it costs to translate a meeting with AI (per-minute math)
How much does it cost to translate a meeting with AI? The good news is you can calculate it precisely, because Langless’s model is transparent: a fixed monthly subscription plus AI minutes paid directly to the provider, with no markup. Below is the per-minute math and examples by duration.

Open LanglessThe cost splits into two parts
- App subscription: from US$ 25/month, which gives you access to the platform (Meeting mode, multilingual rooms, Listen mode).
- AI minutes (BYOK): you use your own OpenAI or Gemini key and pay for the minutes directly to the provider, from ~US$ 0.03/min, with no markup. Langless adds nothing on top of those minutes.
This design is what makes the cost predictable: you only pay for the AI time you actually use.

Cost by meeting duration
Using ~US$ 0.03/min as a reference (the exact figure depends on the provider and the model you choose on your key), the AI-minute cost per meeting looks like this:
| Meeting duration | AI minutes (~US$ 0.03/min) |
|---|---|
| 15 min | ~US$ 0.45 |
| 30 min | ~US$ 0.90 |
| 1 hour | ~US$ 1.80 |
| 2 hours | ~US$ 3.60 |
These figures are just the AI minutes, paid by you directly to the provider. There’s no Langless markup on top of them, and the provider’s price can change — always check on your OpenAI or Gemini account.
Example of a monthly cost
Add the subscription to the minutes to get the total for the month. For example, 8 one-hour meetings = ~480 minutes ≈ ~US$ 15 in AI minutes. Adding the US$ 25 subscription, that’s around ~US$ 40/month — and seats are shared across the team (you pay for concurrent use).
| Item | Estimate |
|---|---|
| App subscription | US$ 25/month |
| 8 one-hour meetings (~480 AI minutes) | ~US$ 15 (directly to the provider, BYOK) |
| Estimated total for the month | ~US$ 40 |
These are estimates: the price of the minutes varies by provider and model. For many companies, translating a whole month of meetings costs less than a single hour of an interpreter. See the plans.
Why BYOK makes it cheaper
BYOK means Bring Your Own Key: you register your own API key and the AI usage is billed by the provider itself, on your account. Because Langless adds no markup on those minutes, you pay the AI’s cost price. Learn more in what BYOK is.
When NOT to use Langless
If the meeting is legal, diplomatic or very high-risk, where every word carries legal weight, the cents-per-minute math isn’t what matters — it’s worth hiring a human interpreter. For business meetings, sales, support and the day-to-day, the AI per-minute cost is unbeatable. Compare in human interpreter or AI.
