Pricing
Langismo itself is free. You bring your own AI key.
There's no subscription and no Langismo-run server in the middle. AI-powered features — translation, dictionary lookups, grammar and idiom explanations, and chat — run against your own API key from Anthropic, Gemini, or DeepSeek, so you pay that provider directly for what you use and nothing more.
Core playback and study tools — bilingual subtitles, saved words, offline text-to-speech — work without any key at all.
