ai-tools2.netlify.app

ai-tools2.netlify.app is a simple web-based utility that bundles three AI-powered tools into one page: a text difficulty converter, a text-to-speech generator, and an audio transcription service. The text converter rewrites passages to match any of six Common European Framework of Reference (CEFR) levels, from A1 to C2. You can paste text directly or upload a PDF, select a model (gpt-4o-mini, gpt-4-turbo, or gpt-4o), and click convert. The other two tools handle audio: turn any text into spoken words using OpenAI's TTS models or upload an audio file to get a text transcript.

Each tool works in chunks to manage API limits. You control chunk size and how many chunks to process. The text-to-speech section lets you pick between tts-1 and tts-1-hd, and choose from six voices (Alloy, Echo, Fable, Onyx, Nova, Shimmer). After generating, you can play individual chunks or the full audio, and download files. The audio-to-text tool uses speech recognition to produce a transcript that you can copy or download as a text file.

The tool requires your own OpenAI API key — it doesn't come with built-in credits. This makes it best for users who already have an API key and want a clean interface for quick text and audio tasks. Language teachers, ESL students, and content creators will find it handy for adjusting reading materials, generating voiceovers, or transcribing recordings. It won't replace a full-featured editor, but for straightforward jobs, it gets the work done.
