Open IPA is a free service, and takes a lot of effort to maintain. If you've found the site useful, please consider donating your time or money to help keep it alive.
Open IPA is community-driven. With the amount of work that goes into the project, support from the community is crucial in making Open IPA the most accurate and helpful tool it can be. With each language offered having its own host of rules, exceptions, and edge cases, it requires more than just one person to keep afloat.
Creating, developing, and hosting a web application does not come without costs. In order to ensure that Open IPA thrives and that development can continue, please consider supporting the project financially. Your support goes a long way towards ensuring that Open IPA stays up, stays accurate, and continues to help transcribe into the future.
