Bloop is an AI tool strategized to assist in the modernization of legacy code. It enables teams to understand, write, and modernize their legacy code more efficiently.

With an emphasis on safety, the code is converted from COBOL to Java automatically, ensuring identical behavior between COBOL and Java programs. The converted code is human-readable, ready for modification, and uses open-source libraries to provide cost-effective solutions.

The tool's continuous delivery characteristic means theres no requirement for a code freeze during the conversion process, ensuring smooth project progression.

A unique feature of Bloop is 'mAInframer-1', a large language model primarily trained for COBOL developers. This aids developers in writing COBOL quicker and more efficiently.

Plus, the extension allows coding entirely offline ensuring no requirement of internet connectivity. Furthermore, Bloop offers the possibility to naturally understand your codebase.

It supports multi-repo search, allowing users to understand interactions between various codebases and services. Moreover, users can ask questions about the codebase in natural language, navigate code conveniently, and find example usage for various languages.

Edited code can be compared with the original using the 'diffing' feature to ensure the scope and specifications are preserved. This tool is designed with an extensive set of features to cater to legacy code conversion, writing, and comprehension needs.

Computers should be allowed to TALK to us for free, like in the Star Trek TV series. Our future grandchildren will laugh at us for "paying" to use this everyday option, biting the hook to "monthly subscriptions" like gullible fish and then getting up to 60,000 characters per month" under the so-called Pro version ;-) This is crazy!
