Value Proposition, Quantified

We give an immersion learner back the 40% they were losing.

For the serious immersion-method learner, native content is the only thing that breaks the intermediate plateau — but raw, half of it is incomprehensible. Babelio's dual-track subtitle layer, plus one-click Anki export, turns wasted, rage-paused hours into clean comprehensible input.

One-line verdict ~$430 in annual value per learner at $144/yr ($12/mo) pricing → roughly a 4-month payback. Value is dominated by reclaimed study time, not cash savings — so the dollar figure is a proxy, and the WTP ceiling, not the ROI, is the binding test.
Bar for good A real immersion learner reads the before-state and says "yes, that's my Tuesday night" — and the after-state without rolling their eyes.

Before · the rage-pause loop Two hours budgeted. Twenty minutes survived.

Before — today, no Babelio

Mei, 24 · 9 p.m. Tuesday

Mei opens a live Japanese VTuber stream on the desktop YouTube client — no fan-sub exists for a live broadcast. She catches ~40%. Every unfamiliar line she pauses, alt-tabs to Yomitan, hovers the word, copies the sentence into Anki by hand, rewinds, relistens. The flow is gone. After ~20 minutes she gives up and rewatches an old, already-subbed clip instead. The real content stays locked. On recorded video she leans on Language Reactor and asbplayer — but only in the browser, never on the native client, never live.

After — same Tuesday, with Babelio

Mei, 24 · 9 p.m. Tuesday

Same stream, same native client. Mei picks the YouTube process in Babelio's capture picker, confirms Japanese, toggles on. Dual-track kicks in: a confidence-shaded caption overlays the video and a quiet whisper-dub sits under the original voice — she still hears the speaker, so she's still training her ear. She follows the whole stream at near-full speed, no alt-tab, no give-up. The lines she wants land in Anki with one click from Session Review, already aligned bilingually. Two budgeted hours become two studied hours. The native, live content she could never touch is finally usable.

The ROI math Dollarizing a consumer's time, honestly.

A learner has no employer hourly rate, so we value their study time at a conservative $6/hr — the price of a tutoring or app subscription hour, not a salary. The before-state assumptions come from the persona: ~2 hrs/night budgeted, but rage-pausing collapses an effective session to ~20 min with ~40% comprehension; native/live content is simply unreachable today. Yellow cells are the live assumptions to refresh after the Week-1 interviews — every number here is a hypothesis until then.

Item Before After Delta $ value / yr
Reclaimed study time Effective comprehensible-input per session ~20 min usable ~110 min usable +90 min × ~5 nights/wk +$234
Unlocked native / live content Streams & native-client video with no fan-sub 0 hrs reachable ~2 hrs/wk reachable +~2 hrs/wk new input +$104
Manual sentence-mining avoided Hover → copy → paste into Anki, by hand ~15 min/night 1-click export ~12 min/night saved +$62
Tool-stack consolidation Replaces part of the Migaku / Reactor / Patreon spend $60–180/yr partial overlap ~$30/yr displaced +$30
Gross annual value per learner ~$430
Why the dollar figure is a proxy, not a sales claim This is a consumer, not a business buyer. A learner does not invoice their study hours, so the $234 reclaimed-time line is real value to them but not cash they'd otherwise have spent. We surface it to size the felt benefit, and we do NOT pitch "save $430" — we pitch "watch live native content and stop rage-pausing." The honest decision-driver is emotional (stop feeling shut out) and behavioral (more comprehensible input per night), with the dollar number as the upper-bound proxy.

Net annual value & payback The formula, with every cell shown.

Net annual value per learner
Reclaimed time = 90 min × 5 nights × 52 wk ÷ 60 × $6/hr = $234
Unlocked content = 2 hr × 52 wk × $6/hr × 0.17 (novelty-discount)$104
Mining avoided = 12 min × 5 nights × 52 wk ÷ 60 × $6/hr = $62
Tool displacement = $30
Gross value = 234 + 104 + 62 + 30 = $430/yr
Less our price = $12/mo × 12 = −$144/yr
Net annual value = 430 − 144 = ~$286/yr
Payback = $144 ÷ ($430 ÷ 12) = 144 ÷ 35.8 ≈ 4.0 months

The binding constraint Strong ROI, fragile willingness to pay.

WTP ceiling-below-floor — the #1 thing to validate

Value is ~3× the price on paper, yet the validated learner willingness-to-pay band is only $6–12/mo, capped by free extensions (Yomitan, Language Reactor's free tier). A heavy daily user's metered subtitle minutes can push our COGS toward the $12 cap. So the ROI does NOT close the deal — the felt-but-uninvoiced nature of the value is exactly why a learner balks above $12. The Week-1 Mom Test interviews and the Week-2 metered-concierge / Van Westendorp test must prove a real cohort pays at this price before tiers lock. If no cohort metered-pays above the COGS floor, the model pivots to usage-metered or a heavier sub-segment.

Cost basis behind the price Why $12 still works for us. Hero mode is subtitle at ~$0.31/active-hr COGS (dub is ~$0.50/active-hr, metered with overage). A typical Pro learner runs ~6 subtitle + ~2 dub hrs/mo → ~$3.26 all-in COGS → ~73% gross margin at $12. The cheap subtitle hero is exactly what keeps the price defensible against the WTP ceiling; dub is metered so heavy use can't punch through margin.
