Built an AI tool to practice speaking — early testers wanted

I recently launched Saynest Lab — a solo-built tool to practice spoken English using AI. You speak to it, it talks back, tracks your mistakes, and helps you improve in real-life conversations.

The idea came from testing GPT for language practice. It worked, but using it efficiently meant constant prompt tweaking. So I built a streamlined interface on top — focused purely on speaking, without distractions or setup hassle.

The MVP is now live.
You choose a topic, talk through short voice sessions, and get feedback on grammar, fluency, and structure — plus targeted exercises based on your weak points.

If you're experimenting with similar tools or interested in AI + language practice — I’d love to hear what you think.
