Dead-code pull requests
ReaperAI used an LLM to remove selected unused types and had an Emerge GitHub bot open a pull request with the proposed changes.

ReaperAI: historical overview
ReaperAI was an iOS-only Emerge Tools service that used dead-code data and an LLM to prepare code-removal pull requests. The managed service is no longer active; Reaper now continues as an open-source, self-hosted project for iOS and Android.

What ReaperAI was
ReaperAI was the automated cleanup layer for Emerge Tools' Reaper SDK. After a team collected runtime evidence about unused iOS types, it could select candidates in Emerge's interface and have a GitHub bot open a pull request containing the proposed deletions.
Emerge Tools no longer offers Reaper as a managed service. The current successor is the MIT-licensed open-source Reaper project, which combines static analysis with runtime usage data to identify dead code in iOS and Android apps. Teams must host and operate that workflow themselves.
Past capabilities
What ReaperAI offered
Runtime-informed selection
The workflow started with usage data collected by the Reaper SDK, helping teams distinguish code seen in real app sessions from potential dead code.
Unused protocol detection
It also used static analysis to identify iOS protocols without conformances as cleanup candidates.
Image optimization
Images surfaced by Emerge's size analysis could be converted or compressed as part of the old managed workflow.
Availability
Why this listing is historical
The managed ReaperAI service is no longer offered. Its open-source Reaper successor has no software license fee under the MIT License, but teams supply their own hosting, integration, monitoring, and engineering time.
- The managed ReaperAI service and its automated pull-request workflow are no longer available.
- The current open-source successor requires teams to operate their own backend and integration.
- Dead-code results still need careful human review because rare paths, reflection, and incomplete session coverage can make active code appear unused.

ReaperAI FAQs
Is ReaperAI still available?
No. Emerge Tools states that Reaper is no longer available as a managed service. The old ReaperAI automation should be treated as a historical product.
What replaced ReaperAI?
Emerge published Reaper as an open-source project for detecting dead code in mobile apps. It supports iOS and Android data collection, but teams must self-host and manage the workflow.
Does open-source Reaper automatically delete code?
Its core workflow identifies likely dead code from static and runtime evidence. The old managed LLM-and-GitHub-bot deletion flow is not part of the current hosted offering, so teams should review and remove candidates through their own engineering process.
