Rehearse the observed lesson before it is observed.
You can teach. An observation adds a second audience at the back of the room, taking notes on every transition.

The evaluator changes the room.
Lessons that run smoothly on an ordinary day tighten under observation. Instructions get longer, pace speeds up, and the plan's timing slips.
- Instructions run long and students lose the thread.
- Nerves raise your pace well above what a class can follow.
- The closing summary gets cut when the lesson overruns.
A classroom that holds you to time.
Kleig rebuilds a classroom's sound and presence so you can run the lesson out loud, at full length, and see exactly where it drifts.

See what the evaluator will see
Pace, clarity, pauses and timing, each with a concrete fix.
Exposure-based practice, rehearsing in conditions that resemble the feared situation, is an established approach in the clinical treatment of public-speaking anxiety, including studies using virtual audiences. Kleig applies the same principle to preparation: you meet the room before the day you meet it.
See, for example, Anderson et al., “Virtual reality exposure therapy for social anxiety disorder,” Journal of Consulting and Clinical Psychology, 2013.
Your recordings are used only to prepare you, stored encrypted, and deletable from Settings at any time. How we handle your data
I am not technical. Is it hard to use?+
No. Setup is a few single questions, and each rehearsal starts with one button.
Does it grade my lesson content?+
No. Kleig evaluates delivery, how clearly and at what pace you teach, not the curriculum.
What happens to my recordings?+
They are used only to prepare you and stored encrypted. From Settings you can delete your profile, rehearsals, feedback and plans at any time.
Is there a free trial?+
No. Kleig is paid-only, so the plans and what they include are stated plainly on the pricing page before you commit.
