Cursor

Also known as: Cursor IDE / Cursor Editor / Cursor AI

VS Code-based AI editor with inline completion, chat, and Agent mode that references the entire codebase as context for refactoring.


Overview

Cursor is highly compatible with VS Code and supports existing extensions out of the box. In Agent mode it can autonomously apply changes across multiple files and execute terminal commands, switching between Claude, GPT, and Gemini as needed.

Positioning vs Competitors

Alongside Windsurf, Cursor is one of the leading AI-integrated editors, adopted by individual developers and large enterprises alike. Whereas Claude Code is CLI-first, Cursor suits developers who prefer a GUI editing experience.

[Crit.md](https://crit.md/) Deep Dive — A Local-First Review Tool That Gives AI-Coding-Agent Output the "Pull-Request Review" Experience, With First-Class Support for Claude Code / Cursor / Copilot / Codex / Gemini / Qwen Four Review Modes (Plans & Docs, Code Diffs, Live Apps, Static HTML), Per-Line Comments Persistent Across Iteration Rounds
**[Crit.md](https://crit.md/)** is a local-first review tool that gives AI-coding-agent output (Claude Code / Cursor / GitHub Copilot / Codex / OpenCode / Gemini / Qwen / ...) a **"pull-request review" experience in the browser**. Four review modes in one UI: Plans & docs (Markdown rendering), Code diffs (syntax highlighting), Live apps (comment directly on the DOM), and Static HTML preview. **Per-line comments** ("click line 47, type feedback, the agent fixes it"), **comments persist across iteration rounds**, **no account required / binds to 127.0.0.1 / zero telemetry**, and a **file-based protocol** (structured review files exchanged with agents — no vendor APIs, no lock-in). Target users: engineers, staff developers, engineering managers. Reduces time spent re-reading terminal diffs, and **keeps humans in the loop instead of delegating all review to agents**. Sits opposite the "fully autonomous" agents in our [Claude Cowork](../columns/claude-cowork-web-mobile-launch-2026-07) and [Devin](../columns/claude-fable-5-return-devin-cursor-2026-07) coverage — a **HITL review substrate for AI output**.

Claude Fable 5 Returns on July 1, 2026 After a 19-Day Shutdown — U.S. Commerce Department Lifts Export Control Amazon's Jailbreak Research Was the Trigger; Anthropic Applied Mitigations Before Resuming Cursor Restored Fable 5 the Same Evening (Leads CursorBench, Most Expensive Per Task); Devin Fusion + Fable 5 Delivers 41% Cost Reduction vs Fable 5 Alone
**Anthropic's Claude Fable 5 and Mythos 5 returned globally on July 1, 2026** after a 19-day shutdown ([CNBC](https://www.cnbc.com/2026/06/30/anthropic-says-trump-admin-has-lifted-export-controls-on-claude-fable-5-and-mythos-5.html) / [9to5Mac](https://9to5mac.com/2026/07/01/claude-fable-5-cleared-to-return-as-us-lifts-anthropics-export-control-restriction/) / [VentureBeat](https://venturebeat.com/technology/anthropic-is-bringing-back-claude-fable-5-globally-after-us-lifts-export-control-order-where-can-enterprises-access-it) / [The Hacker News](https://thehackernews.com/2026/07/anthropic-restores-claude-fable-5-after.html)). **Timeline**: on **June 12 at 5:21 PM ET the U.S. government issued an export-control directive** (directly triggered by [Amazon researchers reporting a jailbreak](../columns/claude-fable-5-export-control-suspension-2026-06)) → Anthropic immediately **shut down Fable 5 and Mythos 5 worldwide** (it had no way to verify user nationality in real time) → **June 26: Mythos 5 was cleared for 100+ U.S. institutions** → **June 30: the Commerce Department lifted controls** → **July 1: global restoration** across Claude Platform / Claude.ai / Claude Code / Claude Cowork / AWS Bedrock / Google Vertex AI / Microsoft Foundry. **Anthropic's mitigations**: the Amazon-reported jailpath was addressed, commitments to "proactively detect and address security risks," collaboration with government on future release protocols, and a reporting channel for observed malicious use. **Fable 5 pricing**: **$10 / M input, $50 / M output** (per apidog). Pro / Max / Team / Enterprise subscribers get an extra allocation up to **50% of their weekly usage limits through July 7**, then usage-credit billing. **Cursor integration**: Cursor officially announced Fable 5 was back at **7:48 PM PT on July 1** on X. "Leads all models on CursorBench — but the most expensive per task," per Cursor ([Cursor Community Forum](https://forum.cursor.com/t/will-fable-5-be-returning-in-cursor/164531) / [apidog setup guide](https://apidog.com/blog/claude-fable-5-cursor/)). **Devin Fusion**: before the shutdown, **Devin Fusion + Fable 5 achieved a 41% cost reduction over Fable 5 alone** using a parallel two-agent architecture, delivering frontier-level performance at **~35% lower cost** (The New Stack). **Enterprise lessons from the 19-day outage**: financial services, healthcare, SaaS, and critical-infrastructure firms lost access to production-embedded tools without warning. The phrase **"frontier access is now conditional infrastructure"** entered the discourse. **Cloud-platform diversification (AWS + GCP + Azure) offers no protection when the model itself is restricted**. OpenAI reportedly **expanded market share** during Anthropic's outage through pre-clearance dealings with regulators (MarketScale). **Strategic context**: [Anthropic released Sonnet 5 on June 30](../columns/claude-sonnet-5-anthropic-release-2026-06-30) — the same day export controls lifted. The timing looks intentional: **Sonnet 5 is positioned as a fallback to Fable 5**, and heading into its IPO, Anthropic now has a clear **two-tier stack** — frontier Fable 5 for peak capability + mid-tier Sonnet 5 for cost-efficient volume.

What Is Cursor for iOS? Control Coding Agents from iPhone and iPad (Composer 2.5, iOS 26+, Public Beta from June 29, 2026)
**[Cursor](https://cursor.com/) (by Anysphere) released its official iOS public beta on June 29, 2026** ([official blog](https://cursor.com/blog/ios-mobile-app) / [Changelog](https://cursor.com/changelog/ios-mobile-app) / [App Store](https://apps.apple.com/app/cursor/id6767085653) / [TechCrunch](https://techcrunch.com/2026/06/29/cursor-now-has-a-mobile-app-for-guiding-your-coding-agent-on-the-go/) / [9to5Mac](https://9to5mac.com/2026/06/29/cursor-releases-iphone-and-ipad-app-following-recent-acquisition-by-spacex/)). **You can now drive Cursor's coding agents directly from iPhone and iPad** (iOS 26.0+ required). Available to all paid-plan subscribers as a public beta, with **75% off Composer 2.5 runs through July 5, 2026**. **Main capabilities**: - **Launch cloud / background agents** or **remote-control desktop-running agents** (with handoff between the two) - **Voice input for task description**, **slash commands** to guide the agent - **Push notifications + lock-screen Live Activities** when work is ready - **Review generated demos, screenshots, logs, and videos**; annotate screenshots - **Inspect diffs and merge PRs** from the phone - **Model selection** across Composer 2.5, GPT (OpenAI), Claude (Anthropic), Gemini (Google), etc. - **MCP integrations** — query Datadog logs, summarize Slack activity, etc. **Strategic context**: this lands alongside the **$60B SpaceX acquisition option on Cursor** (referenced in our [Grok Build column](../columns/grok-build-xai-cli-coding-agent-2026-06)) and operationalizes the **"independent coding agents" thesis** of Cursor 2.0 (Oct 2025). Anthropic's Boris Cherny (Claude Code lead) is quoted saying **"I do most of my coding on my phone now"** (TechCrunch). Joins **Claude Code Mobile / Codex Mobile / GitHub Copilot Mobile** as the fourth major mobile coding-agent surface. **Caveats**: public beta only, the Composer 2.5 promo ends July 5, 2026, no Android or Web yet, requires iOS 26.0+ (older iPhones cannot install), and large-codebase manipulation from mobile alone is still constrained.
