Ok… but I’ve seen plenty of
coding AIs these days.
How does this one actually work?

Catch will plan the work
with browsing docs and examples.

Looks like I can work on this- about 55 files will be modified and it will took 2 hours to send a PR.
Knowledges I will use
Steps
- Update
package.jsonwith removing obsolote dependencies. - Migrate
tailwind.config.cssfor v3. - For all
.tsxfiles in the project directory, I’ll apply the breaking changes.
Validations
I will run eslint to make sure that it works.
Can you confirm my plan? Feel free to suggest on my plan, like correcting steps/validations or dropping any URLs for additional reference!
Or you can choose community-made refactoring recipes.

Catch generates the code by iterating
through the self-validation chain.
With our prioritary validation chain, generated code will be ensured that it compiles correctly and satisfies the requirement given by the user.

Catch will send a pull request and
listen to your feedback.
Review the pull request and leave a comment. Catch will resolve it ASAP, just like an expert engineering teammate.
Secure by design.
E2E Encryption
Code uploads are E2E encrypted, and protected by AES-256 CDC and RSA-4096 encryption.
Local Upload
Connect your local project using CLI with a secure connection, even if you are not using GitHub. Learn More
Sandboxed Environment
Codes are separately stored on a E2E-encrypted sandbox, and deleted after a session.
Frequently Asked Questions
Catch differs from Copilot or Cursor by focusing on large-scale codebase modifications with precision and reliability. While tools like Copilot and Cursor excel at generating shorter code snippets, they often struggle with handling complex, multi-step code changes over extended periods.
Catch, on the other hand, is designed to analyze, modify, and validate long sequences of code without introducing errors, making it ideal for tasks like SDK migrations or framework upgrades.
No, Catch uses its own set of fine-tuned models internally, so external API keys or custom models cannot be used.
No, your code is sandboxed and deleted after the migration process.
Code imports are protected with end-to-end (E2E) encryption using AES-256 and RSA-4096, ensuring that no one can intercept or access your code during the process.
