- Are all these tools really free?
- Many tools work without an account, including the token counter and prompt library. Some generation tools may require login or tokens because they use paid AI models. Create a free account to get more, or upgrade to a Pro or Max plan for higher limits.
- Do I need to log in to use the writing tools?
- The token counter, prompt library, and several writing utilities are available instantly. Tools that generate images or use premium models can require login so usage and tokens can be tracked properly.
- Which AI models power these tools?
- Writing tools run on Claude Sonnet 4 and ChatGPT 4o. Image generation uses FLUX, GPT Image, Recraft, Ideogram, Seedream, and more - You choose the model. See our model comparison page for a full breakdown.
- How is this different from using ChatGPT directly?
- Each tool here has a purpose-built interface and a pre-tuned system prompt, so you get better structured output without needing to write complex prompts yourself. You also get access to multiple models from one place.
- What is the token counter useful for?
- Each AI model has a maximum context window measured in tokens. Use the token counter before pasting long documents into a chat to make sure you stay within limits - Otherwise the model silently truncates your input.
