We are going to build a conversational language tutor that corrects mistakes in real time, adapts its complexity to your proficiency, and maintains context across a long practice session. It is meant for developers who want to drop a speaking partner into an edtech product, or for learners who prefer to own their data and their prompt. Oxlo.ai works well here because its request-based pricing stays flat even when you send long conversation histories or full grammar guides in the system prompt.
What you'll need
You need Python 3.10 or newer, the official OpenAI SDK, and an API key from Oxlo.ai. Head to https://portal.oxlo.ai to grab a key. Install the SDK with pip.
