Frequently Asked Questions

Quick answers for AI Summarizer users

Is the AI Summarizer really free?

Yes! Our AI Summarizer is 100% free with no hidden costs, no registration required, and no limits on the number of summaries you can generate. We believe everyone should have access to powerful text summarization tools.

How does the AI Summarizer work?

Our tool uses advanced AI (DeepSeek via Together.ai) to analyze your text, identify key concepts and themes, and generate a concise summary that captures the essential information. The AI understands context and can adapt to different tones and lengths based on your preferences.

What file formats can I upload?

Currently, we support .txt (plain text) and .docx (Microsoft Word) files. Files must be under 5MB in size. You can also paste text directly into the input box for instant processing without uploading a file.

What's the maximum text length I can summarize?

You can summarize texts up to 15,000 characters (approximately 2,500 words). This is sufficient for most articles, essays, and reports. If your text is longer, we recommend breaking it into logical sections and summarizing each separately.

What's the difference between summary lengths?

Short summaries are 2-3 sentences (50-75 words) for quick overviews, Medium summaries are 1 paragraph (100-150 words) for balanced detail, and Detailed summaries are 2-3 paragraphs (200-300 words) for comprehensive understanding. Choose based on how much detail you need.

What are the different tone options?

We offer 4 tone options: Formal (professional and objective), Academic (scholarly with analytical depth), Creative (engaging and narrative-driven), and Friendly (conversational and accessible). Choose the tone that fits your use case and audience.

What is Focus Mode?

Focus Mode allows you to ask a specific question or provide guidance for the summary. For example, "What are the main arguments?" or "Focus on pros and cons." This helps the AI generate a more targeted summary that addresses your specific needs.

What are Key Points?

Key Points extraction creates a bulleted list of the most important insights, facts, or arguments from your text. This feature is perfect for quick reference, note-taking, and when you need to capture the essence without reading the full summary.

Can I download my summaries?

Yes! You can download your summary as a .txt file that includes the summary text, key points (if extracted), and statistics about the original vs. summary length and compression rate. You can also copy to clipboard with one click.

Is my data saved or stored?

No, we prioritize your privacy. Your text and summaries are processed in real-time and not stored on our servers. Once you close the page, everything is gone unless you download or copy it yourself.

What's the best way to use the summarizer?

For best results, use well-structured text with clear paragraphs. Enable Key Points extraction for quick insights, use Focus Mode for specific questions, and choose the appropriate tone and length for your needs. For academic papers, use academic tone with detailed length.

Can I use summaries for commercial purposes?

Yes! All summaries generated by our tool are yours to use however you like. Use them for research, content creation, reports, presentations, social media, or any other purpose without restrictions or attribution requirements.
