Replit Agent Features & Overview

Replit AI is a browser IDE with LLM-driven coding built in. You open a workspace, describe the goal, and the assistant generates code, proposes diffs, and explains tradeoffs while you stay in flow. The system combines code-aware chat, retrieval over project files, and inline completions. You run servers in the same tab, manage secrets, preview APIs, and hit Deploy when the app is ready. Hosting, logs, and scaling live beside the editor, which keeps feedback tight from idea to production.

Core Features

• AI chat with project context: Ask for a feature, refactor, or fix and receive grounded answers tied to your files. The assistant cites locations, proposes edits, and keeps a threaded record so you can revisit decisions during review.
• Contextual autocomplete: Accept inline suggestions that track nearby symbols, imports, and recent changes. Partial accept lets you take the right fragment, preserve your naming, and keep team conventions intact without extra prompts.
• Agentic code actions: Request structured tasks like add OAuth, migrate a route, or harden input validation. The agent plans steps, edits multiple files, and returns a diff and summary so you approve with confidence.
• Explain and debug: Highlight a block and ask what it does or why a test fails. Replit AI walks through control flow, points at failing lines, and proposes minimal changes that fix the error without drifting behavior.
• Test generation: Generate unit or integration tests from a function, spec, or diff. The tool scaffolds fixtures, mocks external calls, and writes assertions that match intent, which raises coverage without slowing feature work.
• Repo search and retrieval: Query functions, endpoints, and configs across the workspace. The assistant pulls exact matches and similar snippets, then uses those references inside new code so results fit your patterns.
• One-click run and preview: Start servers, open a web preview, and stream logs next to the editor. You spot runtime errors fast, capture stack traces, and ship fixes without switching tools.
• Deployments and hosting: Promote a working project to a live URL with automatic builds, SSL, and asset optimization. You connect a custom domain, review logs, and roll back from the same dashboard.
• Secrets and environment management: Store keys securely, validate required variables, and scope values per environment. Safeguards reduce broken deploys caused by missing tokens or misnamed vars.
• Data and storage options: Wire a quick key value store or connect a managed database. Starters include CRUD hooks, pagination, and optimistic updates so lists feel responsive from the first revision.
• Packages and templates: Bootstrap frameworks and stacks with ready templates. The assistant installs dependencies, configures scripts, and adds example routes so you begin from runnable code rather than empty folders.
• Collaboration and sharing: Invite teammates, comment on files, and share live previews. Reviewers see diffs, notes, and logs in one place, which shortens feedback loops during sprints and hackathons.
