What Is an AI Token? Tokens in AI Apps Explained
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.
Explanation
Language models like GPT-5.2 and Claude process text as tokens - small pieces of words. "Transformation" might be split into 3 model tokens. AI providers bill developers per million of these model tokens, which is precise but hard to predict as a user.
That is why many AI apps simplify pricing into app-level tokens: one token equals one completed AI action, regardless of how many model tokens it consumed under the hood. You do not need to estimate character counts - a short grammar fix and a long rewrite each cost one token.
In Echoo, one token is one successful managed AI command execution: a rewrite, a translation, a summary, or a cleanup. Failed commands do not count, and commands run in BYOK mode (with your own API key) or on local models never consume tokens.
How Echoo Helps
Echoo uses tokens as its pricing unit for managed plans: every new user gets 10 free tokens with no API key or card, Pro includes 400 tokens per month for $6.99, and Max includes 800 for $9.99. BYOK mode and local models bypass tokens entirely - those commands are free at the app level, you just pay your provider directly if it charges.

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.
Context Window
A context window is the maximum amount of text an AI model can process in a single request, measured in tokens. Tokens are roughly equivalent to words (1 token ≈ 0.75 words). Larger context windows allow processing longer documents.

Frequently Asked Questions
No. Model tokens are text fragments the AI reads and writes - thousands can be used in one request. An Echoo token is one successful command execution, whatever its length. It is a simpler unit designed so you never have to count characters.
You can upgrade to Pro (400 tokens/month) or Max (800 tokens/month), wait for your monthly allowance to reset, or switch to the free BYOK mode with your own API key or a local model - BYOK commands never consume tokens.
No. In Echoo, only successful command executions count. If a command fails, your token balance is untouched.
400 tokens means 400 AI commands - about 18 per working day. A grammar fix, a translation, and a rewrite each cost one token regardless of text length, so typical daily writing assistance fits comfortably.
