You upload a PDF, EPUB or text file, or paste a URL — the tool also accepts YouTube links and podcast episodes — and the service preprocesses the content so you can start asking questions even while the full summary is still being generated. Every response is grounded in the source: the app returns detailed references pointing to the passages it used, so you can verify what it claims rather than trusting a black box. The product leans heavily on a playful brand voice (the site jokes that PDF now stands for "Pretty Darn Fantastic"), but the underlying feature set is practical. Document preprocessing scales with file size, large books are handled with their full context, and the Q&A pipeline is described as tested against benchmarks from organisations including Google and Stanford. It also supports multiple languages, responding in the language of your question. Privacy is a stated priority. Documents are stored on encrypted databases, are never used to train external models, and the team says it purges data from third-party providers such as OpenAI on a weekly basis. Retention differs by plan: automatic deletion after one month on the entry tier, six months on the mid tier, and indefinite storage on the top tier unless you delete manually. You can also remove documents yourself at any time. The company contributes monthly to environmental charities through earth.fm and is part of the One Percent for the Planet network. **Pricing & Plans:** Freemium. There is a free tier you can start on without payment, and paid subscription tiers (referenced as Playful, Dynamic and Flagship) that raise document size limits and extend how long stored documents are retained. Check the site's pricing page for current amounts. - **Ask questions across formats:** Upload PDFs, EPUB books, text files or paste a web article link, YouTube video or podcast episode and chat with the content in one interface. - **Answers with references:** Responses are backed by the passages they were drawn from, so you can check the source text instead of taking an answer on faith. - **Full-context book summarisation:** Large documents are summarised with their whole context in mind, which matters for ebooks and lengthy reports. - **Multilingual Q&A:** The system supports many languages and replies in the language of your question. - **Exportable answers:** AI responses can be exported for reports, research notes or your own record keeping. **Strengths:** Handles PDFs, ebooks, web pages, YouTube videos and podcasts in one tool; Answers include source references, which makes verification straightforward; Free tier available to test the workflow before paying; Clear, documented data-retention and deletion policies **Limitations:** Preprocessing time grows with document size, so very large files are not instant; Free tier caps file size, which can block huge books until you upgrade [Profile (Markdown)](https://openaitools.app/tool/aipdf.md) ## Summarify Summarify is an all-in-one summarization workspace built by 1811 Labs. Instead of juggling separate tools for each format, you paste text, a web or blog URL, a YouTube link, or upload a PDF or audio file, and the service produces a concise summary you can read in a fraction of the original time. The interface is deliberately simple: a single input area asks what you want to summarize, with tabs for each source type. Free users can generate summaries instantly, while signing in unlocks history so you can revisit previous summaries. A paid upgrade removes the limits on how many files you can process and adds priority support. Summarify is best understood as a speed-reading assistant rather than a research suite. It is aimed at students, professionals and researchers who need the gist of a long document, article or recording quickly, without reading or listening end to end. **Pricing & Plans:** Freemium. Summaries can be generated for free, and a paid upgrade unlocks a higher file allowance plus priority support. Exact prices and quota numbers are shown after signing in. - **Multi-format input:** Paste raw text, a web or blog URL, a YouTube link, or upload a PDF or audio file from one screen. - **Instant summaries:** Get a distilled summary in seconds without reading or listening to the entire source. - **Summary history:** Sign in to keep a running history of everything you have summarized and revisit it later. - **Audio and video support:** Condense recorded talks, podcasts and YouTube videos, not just written documents. - **Upgrade path:** A paid plan raises the file limit and adds priority support for heavier use. **Strengths:** Handles text, PDFs, web pages, YouTube links and audio in one place; Very short learning curve with a single input box; Free tier lets you try summarization without payment; Signed-in history makes it easy to revisit past summaries **Limitations:** Quota limits on free usage are only revealed after signing in; No public pricing page with specific plan amounts; Summarization focus only, not a full research or citation tool [Profile (Markdown)](https://openaitools.app/tool/summarify.md) ## Frequently Asked Questions ### How do aiPDF and Summarify compare in monthly traffic? aiPDF has 3,816 monthly visits, while Summarify has 0.
