## Contral

Contral is built for the growing number of developers who "vibecode"—shipping features quickly with AI agents—but then cannot explain the code that ends up in production. Its premise is simple: teaching should happen while you build, not after. The platform ships as a standalone IDE and as an extension that drops the same experience onto agents like Cursor, Copilot, Claude Code, Codex CLI, Cline, Kilo Code, Windsurf and Antigravity.

The core workflow has two modes. In Build mode, a repo-aware agent reads, writes and runs code across your codebase with four agent modes (Plan, Fast, Deep and Recursive), and you approve or skip every file write. Alongside each edit, a learning card explains what the code does, why it was written that way, and what the goal is, with line-by-line breakdowns and a follow-up chat for any snippet. When an agent touches multiple files, Contral walks through them in order.

Learn mode adds a structured curriculum inside the editor, currently focused on Java with more than 49 prerequisite-locked topics, graded checkpoints, project challenges, boss exams and a hint economy where hints are earned by completing topics. The company positions Contral as a teaching complement to tools like Cursor rather than a replacement, and it is distributed as a subscription as well as an AppSumo lifetime deal.

**Pricing & Plans:** Freemium with a free tier, a Pro subscription from $9.99 per month billed annually, and a lifetime AppSumo deal starting at $79 for early users (tiers at $79, $139 and $299 with escalating message, deep-dive and analysis limits). Contact options exist for team or enterprise needs.

- **Real-time learning cards:** Every line your agent writes is explained as it happens, covering what the code does, why it was written that way and the intended goal, in the same window.
- **Works with any AI agent:** A VS Code extension brings the teaching layer to Cursor, Copilot, Claude Code, Codex CLI, Cline, Kilo Code, Windsurf, Antigravity and more without changing your agent.
- **Four agent modes:** Plan, Fast, Deep and Recursive modes let you propose before writing, iterate quickly, reason deeply, or let the recursive agent plan multi-step work.
- **Java-first learning curriculum:** 49+ prerequisite-locked topics, projects, graded checkpoints and boss exams inside the IDE, with a hint economy earned by completing topics.
- **You stay in control:** Approve or skip each file write and confirm commands before they run, so the agent never changes your repo without your OK.

**Strengths:** Explains code while the agent writes it rather than leaving learning to later; Compatible with the popular coding agents developers already use; Structured, prerequisite-locked curriculum with checkpoints and projects; Keeps the developer in control of every file write and command

**Limitations:** Learn mode depth is currently centered on Java, with other languages still rolling out; Teaching adds explanation overhead that may slow pure speed-focused workflows; Extension web search and message quotas are capped per pricing tier

## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI
