Voice-Locked Content Repurposing Prompt Pack
One pillar → LinkedIn, X, and newsletter without AI slop.
Voice DNA Scorecard
Paste three real writing samples. The scorecard grades rhythm, lexicon, stance, directness, and specificity so you can lock a Voice DNA block before you prompt.
Pillar Atomizer
Drop one pillar's title, length, and channels. Get atom counts, hook slots, and the number of calendar days the piece can honestly cover — without inventing claims the pillar never made.
Repurposing Cadence Calculator
Model pillars per month against the grid you actually want to hit. See hours required, hours you have, and whether the calendar is a system or a guilt machine.
AI Slop Risk Checker
Paste the draft. The checker flags stock phrases, hedge fog, and empty rhythm. Risk is a score, not a vibe — export the lint report before you hit publish.
Voice Drift Comparator
Put your original next to the rewrite. Drift is measured as vocabulary overlap, sentence rhythm, and first-person stance — then you get three locks to put in the next prompt.
LinkedIn Hook Strength Scorer
Paste the first line of a post. The scorer checks length against the 210-character fold, concrete numbers, who the sentence is about, and whether there is a real curiosity gap — then gives one rewrite cue for your goal.
Newsletter Read-Time Calculator
Words per issue, sections, and reader speed give you a read time, a per-section budget, and the word count that fits the minutes your reader actually gives you.
X Thread Splitter
Paste the long version. The splitter packs whole sentences into posts under your character limit, shows how many posts you get, how full each one is, and where the hook lands.
Hook Variant Test Planner
Posts per week, variants per post, and a test window give you the writing load and the impressions each variant needs before a 'winner' is anything more than noise.
Content Batching Time Estimator
Posts to batch, minutes to draft and edit each, and your break rhythm. Out comes the real session length and how many 90-minute blocks you need to book.
Prompt Context Budget Calculator
Voice samples, instructions, and the draft you want back all spend the same context window. See tokens used, the share of the window, and whether the samples are crowding out the instructions.
Repurposing ROI Calculator
Pillars per month, atoms per pillar, and minutes per atom by hand versus with a locked prompt system. The output is hours saved, what those hours are worth, and how fast a small pack pays back.
First-Person Ratio Checker
Paste a post. The checker counts I, we, you, and they per hundred words and grades the mix against the stance you say you want — personal, brand-we, or mixed.
Post Readability Grade Estimator
A Flesch-Kincaid grade and reading-ease score for any post, with the longest sentence called out and a verdict against the grade level you are aiming for.
CTA Clarity Scorer
Paste the closing line. The scorer checks for a leading verb, a match with the action you actually want, a named thing to get, and a length people can act on in one read.
Content Calendar Gap Calculator
Posts promised, posts published, days left, and pillars in the bank. See the daily pace you now need, how many atoms the bank can honestly cover, and how many new pillars close the gap.
Pull-Quote Extractor
Paste an article. The extractor ranks short, concrete, first-person sentences with numbers and contrast — and hands back the top candidates as standalone quote cards.
LinkedIn Engagement Rate Calculator
Followers, impressions, reactions, comments, and reposts in. Engagement rate on impressions and on followers out — with comment share, because comments are the only number the algorithm and buyers both respect.
Voice Consistency Tracker
Paste three recent posts. The tracker measures shared vocabulary, sentence-length spread, and hedge habits across them, then scores how much they sound like one person.
Podcast Repurposing Planner
Episode length and speaking pace give a transcript size. Clips, quote cards, and honest text atoms per episode add up to a monthly post count and the editing hours behind it.
Writing Sample Sufficiency Checker
Count of samples, average length, formats covered, channels you want to write for, and sample age. The checker says whether the corpus is enough to lock a voice — and how many samples to add.
Jargon Density Checker
Paste the draft and pick who reads it. The checker counts startup and consulting jargon per hundred words against a tolerance for that audience and lists the worst offenders.
Posting Window Timezone Planner
Your UTC offset, two audience offsets, and the local hour you want the post to land. The planner gives the publish hour on your clock for each audience, a compromise slot, and whether it falls inside your working day.
Keyword Density Checker
Paste the post and the phrase you want to rank for. The checker counts occurrences, density per hundred words, whether the phrase appears early, and how many hashtags are too many.
Sentence Rhythm Analyzer
Sentence lengths in, rhythm out: shortest, longest, average, spread, and how many sentences are punches versus marathons. Monotone rhythm is the tell of an unedited AI draft.

Indie SaaS Pricing Decision Kit
A public pricing page you can stand behind — not a sales-assisted pack.
SaaS Pricing Page Modeler
Name three tiers, set monthly prices and mix, and apply an annual discount. The modeler shows blended ARPU, monthly vs annual yield, and a page you can export before you ship HTML.
Value Metric Picker
Answer five questions about how value shows up. The picker recommends a value metric, the fence that belongs on the free/paid line, and the upgrade sentence you should be able to say out loud.
Grandfathering Impact Calculator
Price increases leak through grandfather windows. Model old vs new price, how long you honor the old rate, churn, and how many people upgrade anyway — then export the leakage sheet.
Price-to-CAC Break-even
ARPU, churn, CAC, and gross margin in — LTV, LTV:CAC, and payback months out. If payback is longer than your cash nerve, the price or the channel is wrong.
Tier Fence Designer
Fences only work if real usage hits them. Set starter / Pro limits against median and p90 usage. The designer tells you who is trapped, who never feels the wall, and the upgrade sentence.
Annual Discount Calculator
Monthly price, discount, churn, and uptake. The calculator compares an annual payment to what a monthly customer would actually pay over twelve months after churn — and tells you the break-even discount.
Trial vs Freemium Calculator
Signups, conversion rates for each path, and what a free user costs you to host. The output is paying customers and MRR per path, minus the bill for the free base you would carry.
Usage Pricing Simulator
Platform fee, included units, overage price, and real median and p90 usage. See the median and p90 bill, estimated MRR, and how much of your revenue depends on overage.
Per-Seat Pricing Calculator
Seat price, average and minimum seats, and a volume discount above a threshold. Out comes account value, MRR, and how much the discount leaks on accounts that would have paid anyway.
Price Increase Break-even
Current price, new price, customers, and the churn you expect from the announcement. The calculator gives the break-even churn — the share you could lose and still net zero — and MRR before and after.
Pricing Tier Count Decider
Segments you serve, sales motion, feature groups, price spread, and team size. The decider recommends a tier count, names the tiers, and flags when you do not have enough features to fence them.
Anchor Tier Calculator
Pro price, anchor multiplier, and the share who pick each tier. The calculator prices the anchor, estimates the halo on Pro conversion, and shows MRR with and without the decoy.
Competitor Price Positioning
Three competitor prices, your price, and the stance you want. Out comes the market median, your price index against it, and the number that matches the stance you claim.
MRR Goal Price Calculator
An MRR goal, traffic, signup and paid conversion, churn, and a deadline. The calculator projects customers at the deadline and the price that hits the goal — or how far off a $49 plan lands.
Discount Request Calculator
List price, seats, requested discount, term, margin, and what the account cost to acquire. The calculator shows what you give away, payback with and without the discount, and the maximum discount that keeps payback under a year.
Pricing Test Sample Size
Baseline conversion, the lift you need to detect, weekly traffic, and variants. The calculator returns visitors per variant and weeks to significance — and tells you when a test is the wrong tool.
Net Revenue Retention Calculator
Starting MRR from a cohort, plus expansion, minus contraction and churn. NRR and GRR out, with a read on whether your pricing has an expansion path or just a leak.
Credit Pack Pricing Calculator
Your cost per unit, target margin, three pack sizes, and a bulk step. The calculator prices each pack, shows the effective unit price, and keeps the margin honest as packs get bigger.
PPP Pricing Calculator
US price, a purchasing-power index for the market, and the exchange rate. Get the parity-adjusted price in local currency, rounded to a charm price, and the revenue it unlocks.
Setup Fee vs Monthly Calculator
A setup fee with a lower monthly, versus no fee and a higher monthly. Lifetime value per customer for both, the month they cross, and which one your churn actually favors.
Pricing Page Conversion Calculator
Pricing-page visitors, checkout starts, and purchases. Conversion at each step, revenue per visitor, and a verdict on whether the leak is the page or the checkout.
Lifetime Deal Calculator
LTD price, monthly price, how long a subscriber usually stays, and what supporting a user costs. See how many subscription-months the LTD equals, the support burden over the horizon, and the net.
Feature Gating Scorer
Name the feature, how many users touch it, willingness to pay, build cost, and how much it differentiates you. The scorer says free, Starter, Pro, or Scale — and why.
Refund Policy Cost Calculator
Purchases, price, refund rate, processor fees you do not get back, and the guarantee window. The calculator prices the guarantee per month and the conversion lift it has to earn to pay for itself.
Payment Processor Fee Calculator
Price, transactions per month, and two fee structures (percent plus fixed). Monthly fees and net revenue for each, the difference, and the ticket size where they cross.

Stakeholders, decision makers, how clear the requirements are, change-control discipline, and timeline. The scorer gives a creep risk and the contingency percentage to bake into the fee.
Late Invoice Interest Calculator
Invoice amount, days late, the annual rate in your terms, any flat fee, and the grace period. The calculator gives interest accrued to today, the daily accrual, and the sentence to paste into the reminder.

Proposals sent and won, average deal, hours per proposal, and your rate. Win rate, what each proposal costs you, cost per win, and how many proposals the revenue goal actually needs.
Kickoff Readiness Checker
Five yes/no gates before the first billable hour: signed SOW, deposit in the bank, a named point of contact, access granted, success metrics agreed. The checker scores readiness and names the blockers.
Revision Rounds Cost Calculator
Deliverables, included rounds, hours per round, your rate, and the rounds this client will really ask for. See what the included rounds already cost, what the extras bill at, and the clause that stops round six.
Timeline Buffer Calculator
Your working estimate in weeks, client dependencies, review cycles and their turnaround, and holidays. The calculator adds the buffer the calendar will take anyway and gives you the number to put in the SOW.
Value-Based Pricing Calculator
The client's annual gain, your confidence in it, the share you can capture, your cost-based floor, and what it would cost them to do it in-house. The calculator gives a value fee, a ceiling, and the number to put in the proposal.
SOW Exclusions Generator
Project type, named integrations, environments, and training hours in. A numbered exclusions list out — the things the client will assume are included unless the SOW says otherwise.
Client Concentration Risk
Annual revenue, your two largest clients, and how many active clients you have. The calculator shows the share each carries, the revenue you would need to add to get the largest under 25%, and a verdict.

Subcontractor Markup Calculator
The subcontractor's rate and hours, your markup, and the hours you spend managing them at your own rate. See what you bill, what you keep, and whether the margin is worth the liability.
Proposal Writing Time Estimator
Pages, pricing options, reviewers, how much template you can reuse, and the volume of discovery notes. Out comes the writing hours, business days at a realistic pace, and what the proposal costs you before you win it.
Payment Terms Cash Flow Calculator
