An AI speaking-coach web app that runs on nothing more than a browser and a microphone. Speak for 60 seconds on a given prompt and the AI analyzes the recording, reporting the number of filler words such as “um” and “uh,” your speaking pace (WPM), conciseness, and overall delivery quality as numbers. It also includes interview-prep scenarios and vocabulary exercises, and is designed around short daily sessions that gradually sharpen how you speak. Signing in with a Google account is all it takes to start, and personal practice is free.
Key Features
- 60-second daily practice: Each session is over in a minute. You do not need to set aside a block of time — it fits into the gap before a commute or a meeting
- Prompts generated in three tracks: Randomly generated prompts, interview-prep scenarios, and vocabulary exercises, tailored to your level. You never stall on “what should I even talk about”
- In-depth audio analysis: Filler word counts, pace (WPM), conciseness, and delivery scores are presented as a breakdown, so you see your speaking habits as figures rather than impressions
- Timestamp-linked feedback: Each observation is tied to the moment in the recording it refers to, so you can listen back and hear exactly where you stumbled or sped up
- Streaks and mastery tracking: Consecutive practice days and each mastery dimension are tracked over time, with custom AI suggestions after every session — progress itself becomes the reason to keep going
- No install, entirely in the browser: It works with HTML5 and microphone access, and getting started requires only a Google (OAuth) sign-in

Pros & Cons
✅ Pros
- At 60 seconds per session, the barrier to building a daily habit is low
- Filler counts and pace come back as numbers, which turns vague worries into concrete fixes
- Interview-prep scenarios make it directly usable for job hunting and career moves
- No install and no credit card, so you can try it the moment you think of it
- Feedback is anchored to timestamps, letting you correct yourself while replaying your own recording
⚠️ Cons
- Sign-in is limited to Google accounts; no other authentication method is offered
- Optimized around the 60-second unit, so it is less suited to rehearsing a full-length presentation end to end
- Paid plans, usage limits, and supported languages are not stated publicly, so confirm them before any serious business rollout
- Because it works from audio, a quiet room and a decent microphone affect the results
- It is a relatively new, small service, without the volume of case studies or documentation that larger tools carry

Who Is It For
- Anyone with an interview or presentation coming up who wants to tidy up their delivery quickly
- People who want to cut filler words like “um” and “you know” but cannot catch themselves doing it
- Anyone who wants to rehearse alone, against measurable numbers, before standing in front of an audience
- People who want to measure where they stand for free before paying for a speaking course or a human coach
- Anyone who does better with small daily reps than with occasional long sessions
Summary
Solin narrows speech training down to one idea: speak for 60 seconds and let the AI score you. Because it returns metrics you cannot easily observe in yourself — filler counts, speaking pace — it moves you from a vague sense of “I’m bad at speaking” to specific things to fix. The absence of published paid plans or usage limits is a concern for business adoption, but for personal practice it is free to start. If you have a presentation or an interview on the calendar, it is worth trying as a scorekeeper for your rehearsals.
