Daily 15-minute AI lessons that build real, practical skills
A new lesson lands in your inbox each weekday morning, designed to be completed in about 15 minutes.
Progresses from how AI models work, to building prompts and automations, to embedding AI into your daily workflow.
Lessons pair each concept with a real work task so you produce usable outputs, not just notes.
Everything runs through your existing email and whatever AI tools you already use; no installs or coding environment.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
