Frequently Asked Questions

iSummarizer vs Surge AI: which should you choose?

Choose iSummarizer if you need a quick, affordable text summarization tool for personal use. Choose Surge AI if you are building or evaluating frontier AI models and need expert human feedback, red teaming, or advanced benchmarks. Surge's latest benchmarks (Riemann-bench <10% accuracy for frontier models, Antidote leaderboard) make it indispensable for serious AI alignment work.

Can iSummarizer handle long documents?

Yes, but it uses credits: 1 credit per 1,000 chars for text, and 1 credit per 100 KB for PDF/PPT. For very long documents, costs add up.

Does Surge AI offer a free trial?

Pricing is custom; contact sales. No public free tier exists. Surge is designed for funded organizations.

Which tool is better for cheating on homework?

Neither is intended for unethical use. iSummarizer can summarize readings, but you should cite sources.

Can Surge AI benchmark my custom model?

Yes. Surge provides benchmarks like Riemann-bench, GDP.pdf, and Antidote. You can use their expert graders to evaluate your model.

Does iSummarizer work offline?

No, it is a web-based tool requiring internet connection.

What is the quality of Surge's human feedback?

Surge curates domain experts (writers, doctors, lawyers). The Antidote leaderboard uses expert grading, and Microsoft recently used Surge for benchmarking, indicating high quality.

Is iSummarizer useful for AI development?

Not really. It lacks API and human feedback; it's a consumer tool for summarization, not for training models.

What's the latest benchmark from Surge?

Surge recently launched Riemann-bench for extreme math (frontier models score <10%), GDP.pdf for PDF understanding, and Antidote leaderboard with expert grading. They also released ComplexConstraints for entangled instructions.
