Needed instant realtime whiteboard for meetings so I built it in 1 day
No-signup whiteboard with Mermaid support when Excalidraw already does anonymous.

Free no-signup TTS, but remove.bg and Natural Reader already solved this better.
Anyone needing quick TTS for articles, comments, or placeholder audio; non-technical users.

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.

Another Whisper wrapper with a nice UI, but lacks novelty against Hugging Face Spaces.
Google TTS + Firecrawl + Haiku cleanup is solid execution, but text-to-speech is crowded.
Free DBML-to-PNG when dbdiagram.io already does this with more features.
PDF-to-audiobook CLI with TTS, but similar tools and Google Play audiobook apps dominate.
Instant SSH access without signup is a great DX win for quick testing.
