Time a Portfolio Walkthrough Section by Section — Free
Count the live demo time that a spoken rehearsal leaves out. Flag overlong case studies while keeping the whole walkthrough duration visible for your interview slot.
The proof surface
Interview-answer timers rehearse a single response. This plans a multi-case portfolio with demonstrations that consume their own time, without assessing career fit.
Why the flat version breaks
Skipping demonstration time
A prototype walkthrough is not free time between slides.
Using the ceiling as a total slot
It applies to each case study; the total is shown separately.
Removing every explanation equally
Cut the least useful detail in the overlong section first.
How to work the rehearsal baton
Read the case-study narrative aloud and enter its measured duration. Silent reading is not a rehearsal, and explaining a chart usually takes longer than showing it.
Include navigation, prototype loading and the specific interaction you intend to show. If the demo can fail offline, prepare a still-image fallback and time that too.
Choose a ceiling after reserving introduction, questions and transitions outside this calculator. The starter’s research case is seven minutes against a five-minute ceiling even though the total is fifteen.
Reduce the flagged narrative or demo, not every case equally. Rehearse the full sequence with a timer before relying on the sum; the instrument does not include unlisted pauses.
What the rehearsal baton replaces
| Question | Before | Visible working |
|---|---|---|
| Skipping demonstration time | A prototype walkthrough is not free time between slides. | Measure the live demonstration |
| Using the ceiling as a total slot | It applies to each case study; the total is shown separately. | Set a per-case allowance |
| Removing every explanation equally | Cut the least useful detail in the overlong section first. | Cut a specific section |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Input is processed locally. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
This is rehearsal planning, not hiring advice or a prediction of interview success. Confirm the requested presentation length with the recruiter.
Data note: Everything runs in this browser tab on the rehearsal baton: your case study | spoken minutes | demonstration minutes stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a paper ticker strip
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the rehearsal baton reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The rehearsal baton reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: Choose a ceiling after reserving introduction, questions and transitions outside this calculator. The starter’s research case is seven minutes against a five-minute ceiling even though the total is fifteen.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-27, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: A prototype walkthrough is not free time between slides. After: the rehearsal baton shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this rehearsal baton, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a rehearsal baton. Return plain rows only: case study | spoken minutes | demonstration minutes. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: case study | spoken minutes | demonstration minutes. No AI response is executed as code.
