How it works
Stagefright recreates the feeling of needing to perform, without the consequences of a real audience.

Who it's for
Most people come with a date in the diary. Plenty come to get quicker on their feet. Both start with a sixty-second rehearsal.
The toast you only get to give once.
Team updates, keynotes, a TEDx stage.
Investors, clients, a hiring panel. Answers that still sound like you.
A topic you didn’t pick, sixty seconds, no notes.
Get to the point in meetings, with fewer ums on the way.
Steady eye contact, open posture, hands that help the point.
Audio only
Switch the camera off and talk. Stagefright listens the way your audience will: how your pitch moves, whether your voice carries, how fast you go, and the ums you never hear yourself say.
Try it with your voiceYour speech's journey
A good speech rises and falls. Stagefright maps that emotional journey alongside your delivery scores.
Your words, annotated
Right. Um, good evening everyone. For those of you who don't know me1, I'm Danny, and I've been Tom's best mate since we were, uh, eleven years old. I sort of drew the short straw2 on this one, so, um, please bear with mepause here.
We met in the lunch queue on the first day of secondary school. I did not know a single person in that building. Tom turned round, looked at me, and offered me half of his sandwich. I said yes.2.3s Twenty-five years later he is still feeding me, and I am still saying yes.
And look, Tom is just a really great guy3. Everyone says that about their best mate, I know, but with Tom it is, like, genuinely true. He is a great friend, he is a great brother4, and he is honestly one of the best people I know.

Plain answers about how Stagefright works, what it keeps and what your score means.
Yes. Your first minute can be the opening of your real speech: choose My opening and the coach reads it as an opening, from the hook to how quickly you settle. No speech yet? Choose a random topic instead. After that you can rehearse the whole thing, up to five minutes at a time.
Your video is encrypted in transit and passes through EU-based storage only while Gemini analyses it. We keep no copy: your recording is deleted the moment your report is ready, and we ask Google to delete its copy straight after. Google keeps a record for up to 55 days only to detect misuse of its service, and never uses your recording to train its models.
Usually between 20 and 90 seconds, depending on how long you spoke and how busy the service is. You will see a progress screen while it works. If it ever takes more than a couple of minutes, something has gone wrong and a retry almost always fixes it.
Rehearsal is the most reliable way to bring performance anxiety down. Whether it is stage fright before a wedding speech or nerves before a work talk, the more often you have stood in front of a camera and heard your own voice, the less threatening the real moment feels. Stagefright gives you an honest view of how you actually come across, which is usually far kinder than the anxious version you imagine.
Yes. The coaching looks at your delivery, not at whether you sound like a native speaker. Accent is never marked down. If clarity comes back lower than average, the feedback explains why in practical terms.
Gemini looks at your delivery across five areas: warmth, presence, story, vocal variety, and clarity, with filler words tracked separately. Each area gets its own score, and the overall figure is a weighted blend of all five. It is a coaching signal, not a grade: aim to move it in the right direction over several rehearsals.
There is no account and no sign-up. You get five free rehearsals per browser session: record, get feedback, that is it. We keep no copy: each recording is deleted the moment your report is ready.
Yes. When you begin, you tell Stagefright what you are preparing for, and the coaching takes that context into account. A best man speech is judged differently from a board presentation. There are dedicated starting points for wedding speeches, presentations, TEDx talks, investor pitches, and job interviews.
Yes. Record yourself answering a question the way you would in the room, and you get feedback on your pace, your filler words, and how confident and clear you come across. It works just as well for an on-camera or video interview, where it helps to see yourself back beforehand. Run it as many times as you like until the nerves settle.
As many times as it takes to feel ready. Most people see a real improvement after three or four runs at the same material. You get five rehearsals per browser session, so give the same speech a few focused runs.
