Replit Ghostwriter
Replit Ghostwriter is Replit's coding AI that provides inline code completion, code explanation, code transformation, and code generation inside the Replit editor, introduced as a paid add on priced at $10 per month for 1,000 cycles in the official launch post.
Overview
Replit Ghostwriter is Replit's coding assistant that operates inside the Replit editor and is designed to speed up everyday programming tasks. In the official launch post, Replit describes four core capabilities: Complete Code for inline suggestions, Explain Code for plain language walkthroughs, Transform Code for refactoring and rewriting based on instructions, and Generate Code for creating functions and program components from prompts. These features target the moments developers lose time, like boilerplate, understanding unfamiliar code, and quick refactors.
The same post introduces Ghostwriter as a paid add on and states a price of 1,000 cycles for $10 per month. Because Replit has since expanded its AI offering with Agent and Assistant billing, Ghostwriter should be evaluated as part of the broader Replit AI ecosystem rather than a standalone tool. Confirm in your current Replit account which AI features are available, how they are billed, and whether Ghostwriter functionality is included in your plan or still a separate add on.
From a workflow perspective, Ghostwriter is best used where you can keep tight control over changes. Inline completion can be helpful for repetitive code, while Explain Code can support onboarding and review. Transform Code and Generate Code should be used with tests and code review, because suggestions can compile while still being incorrect or insecure.
Before team rollout, run a pilot with a representative repo, measure acceptance rate of suggestions, and confirm any policy constraints for sending code context to an AI service. Pair it with budget alerts and review practices to keep both cost and risk predictable.
Key features
- Inline completion: Complete Code provides inline suggestions as you type so you can draft boilerplate faster and stay in flow
- Explain selected code: Explain Code describes highlighted blocks in plain language so teammates can review logic and learn faster
- Transform refactors: Transform Code rewrites a selected block from your instructions so refactors and style changes are quicker
- Generate functions: Generate Code creates functions and program pieces from prompts which helps you scaffold new modules rapidly
- Editor integrated flow: Ghostwriter runs inside the Replit editor so suggestions use local context from your files and comments
- Works across devices: The launch post positions Ghostwriter as available wherever Replit runs including desktop and mobile web
- Purchase add on: The launch post describes a paid plan measured in cycles with 1
- 000 cycles per month as the starter allowance
- Docs and FAQs: The post links to Ghostwriter docs and FAQs to explain the four tools and how to activate them in your workspace
Best for
- Boilerplate generation: Use inline completion to draft repetitive code like handlers and data models while keeping style consistent
- Code comprehension: Highlight unfamiliar code and request an explanation to speed onboarding and reduce review back and forth
- Refactor assistance: Ask Transform Code to rewrite a block for readability or performance then validate with tests and linting
- Quick scaffolding: Generate starter functions from a prompt then fill in business logic and edge cases with manual review
- Learning exercises: Use explanations while coding tutorials so you understand what code does rather than copy pasting blindly
- Debug support: Generate hypotheses and small fixes then run the program and tests to confirm behavior matches expectations
- Documentation drafts: Turn a function into a short explanation that you can adapt into comments or internal docs for teammates
- Pair programming flow: Use Ghostwriter during code review to explore alternatives while keeping final decisions with humans
Capabilities
Inline code complete
Get inline suggestions as you type using the Complete Code feature. Works best for boilerplate and repetitive patterns while you still review and commit final edits.
Explain code blocks
Highlight code and request an explanation in plain language. Helpful for onboarding and code reviews where you need quick understanding of unfamiliar functions or logic.
Transform and refactor
Ask Ghostwriter to rewrite selected code to apply changes you describe. Use tests and linters to confirm behavior because refactors can introduce subtle bugs.
Generate new code
Describe a function or component and have Ghostwriter generate starter code. Treat it as scaffolding then add edge cases security checks and documentation.
Frequently Asked Questions
What is the starting price for Replit Ghostwriter?
In the official Ghostwriter launch post, Replit described a plan of 1,000 cycles for $10 per month. Because Replit now offers Agent and Assistant billing, confirm in your current account whether Ghostwriter is sold separately or bundled.
What coding tasks does Ghostwriter support?
The launch post lists four tools: inline completion, explain code, transform code, and generate code. Use completion for boilerplate, use explanations for understanding, and validate transforms or generated code with tests and review.
Does Ghostwriter send my code to an AI service?
Ghostwriter operates as a cloud AI feature inside Replit, so some code context may be processed to generate suggestions. Review Replit privacy and security documentation, avoid inserting secrets, and follow your org policy for source code handling.
How much setup is needed to use Ghostwriter?
Activation is designed to be lightweight inside Replit. The main setup work is procedural: define when AI suggestions are allowed, require reviews for generated changes, and standardize tests so the team can trust outcomes.
When should I choose Ghostwriter vs Replit Agent?
Ghostwriter assists within your editor while you drive changes line by line. Agent aims to build larger chunks of functionality autonomously. Choose Ghostwriter for incremental coding and choose Agent when you want rapid end to end scaffolding.
