TextSynth is an AI platform that provides access to a wide array of open-source language models and speech-to-text capabilities. Designed for developers, tinkerers, and researchers, it enables users to generate text or transcribe audio using models such as GPT-J, GPT-NeoX, and others, directly via API or a simple web interface.
What sets TextSynth apart is its transparency and flexible usage. The Free Plan includes limited access with captcha checks and token caps, while the Standard Plan removes those barriers and offers credit-based usage. No user content is stored under the paid plan, emphasizing privacy. Whether you're building a chatbot, summarizing content, or testing language model behaviors, TextSynth offers raw AI performance at your fingertips.
