What Is a Managed API Key? AI Apps Without API Setup
A managed API key is an arrangement where the app developer holds the API credentials to an AI provider and routes your requests through them, so you never have to create, fund, or store an API key yourself.
Explanation
Using an AI provider directly requires signing up, adding a payment method, generating an API key, and pasting it into your tool - a real barrier for non-developers. With a managed key, the app does all of that behind the scenes: you install, and AI features simply work.
The trade-offs: managed access is usually metered (a monthly allowance of actions or tokens) and requests route via the vendor's account. The alternative is BYOK (Bring Your Own Key), where you supply your own provider key - more setup, but unmetered by the app and billed directly by the provider.
Many modern AI apps offer both: a managed mode for instant, zero-setup use, and a BYOK mode for power users who want direct provider control.
How Echoo Helps
Echoo ships with a managed key so it works the moment you install it: your first 10 tokens are free with no API key or card, and Pro ($6.99/month, 400 tokens) and Max ($9.99/month, 800 tokens) continue on the managed key. Power users can switch to the free BYOK mode - your own OpenAI, Anthropic, or Google key stored in Apple Keychain - or run local models via Ollama with no key at all.

API Key
An API key is a unique string of characters that authenticates your requests to an AI service. When you use tools like OpenAI, Anthropic, or Google Gemini, your API key proves your identity and tracks your usage for billing.
BYOK (Bring Your Own Key)
BYOK (Bring Your Own Key) is a model where an AI tool lets you use your own API key from an AI provider rather than routing your data through the tool's servers. This gives you direct control over privacy, costs, and model selection.
AI Token
An AI token has two common meanings: in language models, a token is a chunk of text (roughly 3-4 characters) that the model reads and generates; in AI app pricing, a token is a usage unit - typically one AI action or command execution.
Local LLM
A local LLM (Large Language Model) is an AI model that runs entirely on your own computer instead of in the cloud. Tools like Ollama, LocalAI, and LiteLLM make it easy to run models locally on Mac.

Frequently Asked Questions
Requests route through the vendor's provider account instead of yours. Echoo does not store your processed text in either mode; if you want text to go only to a provider account you control - or never leave your Mac - use BYOK mode or local models.
The vendor pays the AI provider for every request, so managed plans meter usage - in Echoo's case, tokens per month. BYOK mode is unmetered by Echoo because you pay your provider directly.
No. The 10 free tokens and the paid plans run entirely on the managed key. Your own key is only needed if you choose BYOK mode for unmetered use or a specific provider setup.
Yes, anytime. Start on the managed key with zero setup, and add your own key later if you want unmetered usage, a specific model, or local processing via Ollama.
