Frequently asked questions
What is the difference between AI-based and statistical summarisation tools?
AI-based tools like ChatGPT and Claude use large language models trained on vast amounts of text to understand meaning and generate natural summaries that may paraphrase content. Statistical tools like Smmry identify important sentences using algorithms and extract them verbatim. AI approaches typically produce higher-quality, more natural summaries, whilst statistical tools are faster and simpler but less nuanced.
Which tool is best for summarising academic research papers?
Scholarcy is purpose-built for academic papers and automatically extracts structured information including hypotheses, methods, results, and citations. For general research, Claude and ChatGPT also perform well due to their ability to handle complex technical language, though they require manual prompting to match Scholarcy's structured output.
Are there completely free AI summarisation tools without limits?
ChatGPT and Claude both offer free tiers with reasonable capabilities, though they may have usage restrictions. Smmry and the basic versions of Quillbot and Wordtune are completely unlimited and free, but use statistical rather than deep AI methods. Most premium AI tools cost between £5 and £20 monthly for unlimited access.
