## aiPDF

aiPDF turns long documents into something you can interrogate. 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

## Grok

Developed by xAI, Grok has transformed from an X-exclusive chatbot into a standalone frontier AI ecosystem accessible at grok.com, on iOS and Android, inside the X platform, and via the xAI API. By late 2026, xAI retired the original Grok 3 and initial Grok 4 checkpoints in favor of an upgraded Grok 4 family led by Grok 4.7 (released September 21, 2026, 500K-token context window), alongside Grok 4.5, the 1M-context Grok 4.3, the 2M-context Grok 4.1 Fast, and the specialized Grok Build 0.1 coding model.

Grok differentiates itself through unfiltered real-time information retrieval and an integrated creative and coding suite. Its DeepSearch engine synthesizes live breaking news, public sentiment, and primary discussions directly from the X firehose alongside the open web—giving it a distinct real-time edge over static-cutoff competitors. Within the grok.com workspace, paid users share a unified weekly compute pool across conversational reasoning, Voice mode, Imagine (native photorealistic image and video generation), Grok Bot automation, and Grok Build (which replaced the older Grok Studio as xAI's dedicated agentic coding environment).

In October 2026, xAI streamlined its consumer pricing by unifying standalone SuperGrok plans and X Premium memberships into The X Subscription—bundling full Grok access, X Premium perks, and the Cursor code editor across five tiers: Free ($0), Plus ($8/month), Premium ($30/month, matching the classic $30/month SuperGrok tier), Super ($100/month, matching SuperGrok Plus), and Ultra ($200/month), while legacy SuperGrok Lite ($10/mo) and Heavy ($300/mo) subscribers remain grandfathered and Grok Business serves teams at $30/seat/month. On the xAI API, flagship Grok 4.7 is aggressively priced at $2.00 per million input tokens ($0.50 cached) and $6.00 per million output tokens for prompts under 200K tokens.

**Pricing & Plans:** Free tier ($0) with limited access; unified October 2026 X Subscription tiers at $8/mo (Plus), $30/mo (Premium / legacy SuperGrok), $100/mo (Super / legacy SuperGrok Plus), and $200/mo (Ultra) bundling Grok, Cursor editor access, and X perks; Business at $30/seat/mo; xAI API at $2/1M input and $6/1M output for flagship Grok 4.7.

- **Grok 4.7 Flagship Reasoning & Coding Model:** Features configurable reasoning, low hallucination rates, native agentic tool calling, and a 500K-token context window (with up to 2M tokens on Grok 4.1 Fast).
- **Real-Time X Firehose & DeepSearch:** Combines live web browsing with direct access to real-time posts, threads, and breaking events on X to deliver up-to-the-minute synthesis.
- **Grok Build & Cursor Subscription Bundle:** Provides a dedicated agentic coding environment with Grok Build 0.1 and Grok 4.7 Fast, while October 2026 subscription tiers bundle access to the Cursor code editor.
- **Imagine Multimodal Image & Video Generation:** Generates high-resolution images and video clips alongside real-time speech-to-speech Voice mode from a single shared weekly usage pool.
- **High-Value xAI Developer API:** Offers Grok 4.7 at $2/1M input and $6/1M output tokens ($0.50/1M cached input), plus a realtime Voice API ($0.08/min STS) and 20% batch discounts on Grok 4.3.

**Strengths:** Unrivaled real-time awareness via exclusive access to the live X social graph paired with DeepSearch web browsing; Flagship Grok 4.7 API ($2 input / $6 output per 1M tokens, $0.50 cached) significantly undercuts OpenAI and Anthropic flagship token pricing; Unified October 2026 subscription ($30/mo Premium, $100/mo Super, $200/mo Ultra) bundles Grok, X perks, and the Cursor code editor; Massive context windows ranging from 500K tokens on Grok 4.7 to 1M on Grok 4.3 and 2M on Grok 4.1 Fast

**Limitations:** Consumer paid plans draw Chat, Imagine media generation, Voice, and Grok Build from a single shared weekly quota that heavy multi-tool users can exhaust; API prompts exceeding 200K tokens double the rate for the entire request ($4/1M input and $12/1M output on Grok 4.7); Frequent 2025-2026 plan restructurings (X Premium+ to SuperGrok tiers to October 2026's unified X Subscription) create confusion around legacy vs. current tiers
