Frequently Asked Questions

Are these AI tools truly free to use?

Yes! All of our AI tools, including the AI code explainer and AI essay writer, are completely free. There are no subscription fees, token limits, or hidden paywalls.

Do I need to create an account or provide an API key?

No. You do not need to sign up, provide an email, or bring your own API key. Simply navigate to the tool and start generating immediately.

What AI model powers these tools?

Our tools are powered by state-of-the-art Large Language Models (LLMs), primarily leveraging Google Gemini to provide fast, accurate, and highly contextual responses.

Is the AI code explainer safe for proprietary code?

We do not store your code or use it to train our own models. However, standard API privacy policies apply as the data is processed by the LLM provider. Do not submit highly sensitive API keys or credentials.

Can the AI paraphraser avoid AI detection?

Our AI paraphraser is designed to improve readability and adjust tone. While it produces highly human-like text, we recommend using it as a writing assistant rather than a tool to bypass academic integrity systems.

How accurate is the AI grammar checker?

The AI grammar checker goes beyond traditional spell-checkers by understanding deep context. It catches complex grammatical errors, comma splices, and awkward phrasing that standard tools miss.

Are there any limits on how much text I can process?

While there is no strict daily limit, we employ reasonable rate-limiting and character limits (e.g., 2000-5000 words per request) to ensure the service remains fast and stable for all users.

Can the AI essay writer generate citations?

The AI essay writer provides excellent structural frameworks and content. However, we always recommend verifying facts and manually adding academic citations, as AI models can occasionally hallucinate specific sources.
