24 alternatives to SonicFlow
Hi HN, I made a simple web tool called SonicFlow (https://voice.clevermock.com) for converting text to an MP3. I've used other TTS tools, but was looking for something with zero friction - no sign-up, no feature-gating, no complicated SSML tags to learn. Just a text box and a download button. So I built it. It's a clean front-end that pipes text to a TTS model and serves the audio file directly. Useful for quickly listening to articles, comments, or maybe generating placeholder audio for a project. It's free. Hope it's useful. Feedback is welcome.

Hi HN! I'm stoked to share a project I've been working on called PDF to Podcast. It's a free, open-source tool that automatically converts PDF documents into engaging, informative podcast-style audio content using large language models and text-to-speech tech. Inspiration: The idea for this project came from the NotebookLM demo at Google I/O, where they showcased generating audio dialogue from uploaded PDFs and other sources. However, that audio feature hasn't been publicly released yet, and I wanted to challenge myself to build something similar using existing tools and APIs. How it…

I originally added this to my site to speed up my video editing process. Last year I started a youtube channel and for some of my longer videos it's annoying to rely on youtube or capcut to transcribe when Whisper is open source. Capcut also recently updated their T&Cs to say they own your content if you use their app, so I cancelled my subscription. Another use-case I have is recording my claude prompts as audio, transcribing them, and then pasting them into my terminal. I mostly work on the CLI (claude, ffmpeg, whisper), but I wanted to make a browser version. Not reinventing the wheel…

Hi HN, I’m Michael, creator of AudiowaveAI. I started this project out of frustration when I couldn't find an audiobook version of Make by Pieter Levels. The available text-to-speech options were either too robotic, overly complex, or simply too costly. It works really well for non-fiction long-form content (i.e. hours of audio). It’s early days for AudiowaveAI, and I’m looking for feedback to improve the product. Try it out and share your thoughts: [AudiowaveAI](https://audiowaveai.com). Thanks!
