A/B Test Planner: common questions

Is A/B Test Planner free to use?

Yes. A/B Test Planner is completely free with no registration — it runs entirely in your browser as a client-side analysis tool.

Does A/B Test Planner upload my data to a server?

No. All processing happens locally on your device. Your input never leaves your browser, which makes the tool safe for confidential content.

How accurate are the results?

The tool runs deterministic, transparent logic in your browser. Results are calculated exactly as described and are intended as a helpful starting point — always double-check critical business decisions independently.

What does the analysis include?

Word and character counts, sentence and readability metrics, key term extraction, structure notes and extracted data such as URLs or hashtags — all computed on your device.

Is my text stored anywhere?

No. Your input is analyzed in memory and discarded when you leave the page — it is never sent to a server or saved.

Is the A/B Test Planner suitable for beginners?

Absolutely. The A/B Test Planner was designed so a first-time user gets a correct result on the first try, while still offering the depth experienced conversion optimization practitioners expect.

Can I use the A/B Test Planner on my phone or tablet?

Yes. The page is fully responsive and the tool runs on any modern mobile browser — nothing to install, and since processing is local it works on mobile data just as fast as on Wi-Fi.

A/B Test Planner: the case for a dedicated tool

Most conversion optimization work stalls because the answer lives in a spreadsheet tab, a paywalled dashboard, or a colleague's head. The A/B Test Planner removes that friction: open the page, enter what you know, and get a usable answer in seconds.

Learning by doing beats learning by reading. Paste real material into the A/B Test Planner, watch how the results change with your edits, and you build intuition for conversion optimization that no course can teach.

Manual checks are fine once, but nobody repeats a manual checklist reliably. The A/B Test Planner encodes the checklist once and applies it identically every time you run it.

When to use the A/B Test Planner

t => `Study and practice: analyzing strong public writing to see what makes it strong.`
t => `Comparing two drafts to decide which direction to develop.`
t => `Understanding why a piece that "reads fine" still underperforms — the metrics find the suspects.`
t => `Editing your own drafts with objective feedback before a human editor sees them.`
t => `Pre-publication checks on tone, readability, and structure for ${t.subcategory.toLowerCase()} content.`

Tips for best results

t => `Compare the key terms in the output against the terms you intended to rank for — a mismatch is your revision plan.`
t => `If readability scores run high (difficult), shorten sentences before you simplify vocabulary; structure moves the needle more.`
t => `Paste enough text for a meaningful read — a single sentence gives the ${t.name} little to measure; two or three paragraphs give it a voice.`
t => `Run your draft before your final version; the biggest metric improvements come from early structural edits, not last-minute polish.`
t => `Nothing you paste is uploaded anywhere, so use real drafts, not sanitized placeholders — the honest input gives the honest profile.`

Common mistakes to avoid

t => `Pasting sensitive third-party content and worrying about privacy: nothing leaves the browser, so analyze freely.`
t => `Assuming a good score means good writing — the metrics flag mechanical issues, meaning and voice are still yours to judge.`
t => `Optimizing a single metric (word count) while ignoring the structure and key-term signals next to it.`
t => `Analyzing a rough outline and expecting final-quality insights — the ${t.name} profiles what is actually on the page.`
