Offline Grammarly Alternative for Mac - Local AI with Echoo
Run proofreading and rewriting on your Mac with a local model, even without an internet connection.
Echoo is an offline Grammarly alternative when connected to a local model through Ollama: proofreading and rewriting happen on your Mac without sending text to Grammarly or another cloud provider. Local-model quality depends on the model and hardware, so Grammarly may remain more polished for passive inline checking.
