PlainTerms の代替ツール
PlainTerms is an AI-powered tool designed to turn lengthy terms of service and privacy policies into clearer, more approachable explanations. The project description says it supports English and Spanish and includes an opt-out assistant intended to help users find ways to limit data sharing, personalized advertising, and other privacy choices. Its appeal is practical: people rarely read every line before signing up for a new app, but a quick plain-language overview can reveal important permissions and retention policies. The product’s official website is still under construction, so pricing, supported platforms, accuracy, and launch details have not yet been confirmed.
PlainTerms aims to use AI to explain terms of service and privacy policies in plain English, but its official site is still under construction, with no public information on pricing, platforms, or launch timing, and no mention of Chinese support. If you need a summarization tool you can use today, this comparison covers several immediately available alternatives for summarizing and extracting information from files, web links, videos, and multiple content sources, so you can choose based on your workflow.

Niyah is an AI reading assistant that turns your own EPUB, PDF, DOCX, and TXT files into structured summaries you can read or hear. It is designed for students, researchers, and busy professionals who have useful books and reports sitting unread because time is limited. The free tier provides two summaries per month without requiring an account, while the $10-per-month Pro plan raises the allowance to three books and adds larger files, syncing, and priority support. A separate $19-per-month Full-Book Audio add-on can generate chapter-level audio for complete books. Niyah is convenient, but its 2MB free file limit and the usual risks of AI summarization deserve attention.
代替として優れている理由
Niyah lets you upload your own EPUB, PDF, DOCX, and TXT files to generate structured summaries. Its free tier does not require registration, and its pricing plans are clearly presented, making it more suitable than PlainTerms for working directly with policy or terms documents you already have.

- Structured summaries are easier to scan than a single block of text
- Summaries can be read or heard, with offline downloads available
短所
- The free tier’s 2MB file limit may exclude some PDFs

選び方
If you need to process local files, such as terms in a PDF or Word document, Niyah is the most direct option: upload your own files and generate a structured summary. If you mainly read terms on your phone, Later saves links through the system share menu and summarizes them automatically, eliminating manual filing. If you rely on YouTube for policy explainers, AI Summary is free and lets you switch between ChatGPT, Gemini, Claude, and DeepSeek as the backend, while Eightify stands out for its five-second summaries and support for more than 40 languages. If you track explanations across multiple channels, MurmurCast combines YouTube, podcasts, and newsletters into a daily briefing. None of these tools is specifically trained for legal text, but all can handle extraction and summarization; verify important details against the original source.
