Open LanglessCost
A human interpreter is usually billed by the hour or by the day, often with a minimum of several hours — which makes short or unplanned meetings expensive. Langless’s AI translation uses the BYOK model: you pay per minute directly to the AI provider (from ~US$ 0.03/min), with no markup, plus the app subscription (from US$ 25/month). For most business meetings, it works out to a fraction of the price. See how much a simultaneous interpreter costs.

Speed and availability
A human interpreter has to be booked and depends on their schedule. AI is available 24/7, on the spot: open the app, pick the languages and you’re already translating. For last-minute meetings, customer support and everyday conversations, that difference matters a lot.
Languages
Finding a good interpreter for less common language pairs can be hard and expensive. AI covers dozens of languages instantly, in both directions, with no need to track down a specific professional for each combination.
Quality and context
In high-stakes situations — hearings, sensitive legal contracts, diplomatic settings — a human interpreter still has the edge in nuance, culture and professional accountability. For business meetings, sales, support, interviews and day-to-day work, AI translation already delivers fluent, sufficient communication in real time.

Side-by-side comparison
To make the decision easier, here are the two models head to head. These are general observations — a human interpreter varies a lot by language, region and type of event, so treat the cost and availability fields as illustrative.
| Criterion | Human interpreter | Langless (AI) |
|---|---|---|
| Cost | By the hour or day, usually with a minimum number of hours; varies widely by language and event | Subscription from US$ 25/month + ~US$ 0.03/min directly to the provider (BYOK), no markup |
| Availability | Must be booked; depends on the professional’s schedule | 24/7, on the spot: open the app and it’s translating |
| Languages | 1 pair per professional; rare pairs are hard and costly to find | Dozens of languages instantly, in both directions |
| Setup | Booking, possible travel and equipment (booth, headsets) | Virtual audio cable (one-time setup) to get into Zoom, Teams and Meet |
| Best for | Legal, diplomatic and very high-risk settings, where every word carries legal weight | Business meetings, sales, support, interviews and the day-to-day |
When to use each
- Use a human interpreter when the context is legal, diplomatic or very high-risk, and every word carries legal weight.
- Use AI translation for meetings on Zoom, Teams and Meet, negotiations, support, chat rooms and frequent conversations — where speed, cost and availability matter.
