## 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

## Isaac

Isaac is built around the idea that academic writing is not one task but a chain of them: finding sources, reading closely, taking notes, drafting, revising, and citing. Rather than stitching together a reference manager, a chat assistant, and a word processor, Isaac folds these into a single desktop workspace so the material you gathered stays within reach while you write.

At its center is an academic-tuned AI assistant. It can autocomplete sentences, paraphrase passages, summarize documents, and help produce a first draft, all while you keep control of the final text. A literature search feature lets you find relevant papers inside the app, and a reference management panel keeps them organized. You can also upload papers directly and ask questions about their contents, which shortens the loop between reading and writing.

The service is used by tens of thousands of researchers and is available in 16 languages, with data hosted on GDPR-compliant EU servers. Pricing runs from a free-forever tier with modest daily AI tokens up to paid plans with higher token allowances, file uploads in chat, and premium models.

**Pricing & Plans:** Freemium. Free: $0 forever, no credit card, 10 daily AI tokens and 100 MB file storage. Basic: about $8/mo billed annually, 50 daily AI tokens, 1 GB storage, file uploads in chat, and first-draft generation. Pro: about $16.66/mo billed annually (around $25 monthly), unlimited AI and chat, unlimited file storage, premium AI models, and priority support.

- **Academic AI assistant:** A ChatGPT-style assistant tuned for scholarly writing, with autocomplete, paraphrasing, summarization, and first-draft generation.
- **Literature search and references:** Search relevant academic literature inside the app, then keep sources organized in a reference list beside the editor.
- **Chat with documents:** Upload your papers and ask questions about them, so you can interrogate a source without leaving your document.
- **Workflow automation:** Automated functions help streamline literature reviews and other repetitive research tasks.
- **Unified writing workspace:** A distraction-free editor that keeps writing, sources, and AI support in a single desktop window.

**Strengths:** Brings literature search, referencing, and AI writing into one workspace; Free-forever tier for students who want to try it; Available in 16 languages; Data hosted on GDPR-compliant EU servers

**Limitations:** Desktop only — no mobile app yet; Free tier is limited to 10 daily AI tokens; No guarantee of originality; you still need to review cited output; Some workflow features are marked as coming soon
