Can you help me understand the differences between the AI models you offer and when I should use each one?
Of course! Here's a quick overview of the AI models available in aChat and when you might want to use each one:

Claude 3.5: Great for detailed, nuanced responses, creative writing, and understanding complex instructions. Use for long-form content, thorough explanations, and when you need thoughtful analysis.

GPT-4o Mini: Good balance of capabilities with fast responses. Great for coding help, general information, and everyday tasks.

Gemini Pro: Excels at knowledge-heavy tasks, step-by-step reasoning, and understanding context. Good for educational content and explanation.

Frequently Asked Questions

Get answers to common questions about aChat.

How do credits work and how many do I need?
Credits are consumed based on the length and complexity of your conversations. Short questions might use 200-500 credits, while detailed conversations with file analysis can use 3,000-5,000 credits. The 5,000 free signup credits let you explore the platform thoroughly. Basic plan ($9.99/month) includes 100,000 credits, suitable for 20-50 medium-length conversations per month. Pro plan ($19.99/month) includes 300,000 credits, ideal for daily active use.
Which AI models are available and when should I use each one?
aChat gives you access to five leading AI models: Claude 3.5 (excellent for nuanced writing and complex reasoning), GPT-4o Mini (versatile for general questions and coding), Gemini Pro (great for factual information and analysis), DeepSeek-R1 (specialized for programming tasks), and O3 Mini (fast responses for simple queries). You can switch between models anytime during a conversation to leverage each model's strengths.
What happens to my subscription credits if I cancel?
When you cancel a subscription, you'll immediately lose access to any remaining subscription credits. Your account will remain active, and you can still access your conversation history, but you'll need to purchase additional credits or resubscribe to continue using the service. There are no refunds for unused portion of subscription periods.
What file types can I upload for AI analysis?
aChat currently supports uploading text files (.txt), code files (.js, .py, .html, .css, .json, .ejs), and image files (.jpg, .jpeg, .png, .gif, .webp). The AI can analyze the content of these files, extract information from images, understand code structure, and provide insights, explanations, or answers to your questions about the uploaded content.
Can I switch between AI models during a conversation?
Yes! You can switch between any of our available AI models at any point in a conversation with a single click. This is one of aChat's key features - the ability to choose the best AI for each specific question or task, all within the same conversation interface. For example, you might use Claude 3.5 for creative writing, then switch to DeepSeek-R1 for help with coding.
How long are my conversations stored?
Your conversations are stored indefinitely as long as you maintain your account. You can access your full conversation history at any time, making it easy to reference previous discussions or continue conversations where you left off. All conversations are privately accessible only to you.
Is there a limit to the number of conversations I can have?
There's no limit to how many separate conversations you can create and save. The only limit is the number of credits in your account. Each conversation consumes credits based on its length and complexity, so your monthly credit allowance determines how much you can chat. The Basic plan provides enough credits for 20-50 medium-length conversations per month, while the Pro plan supports daily active use.
