**Direct Answer:** Hypefury is a social scheduler with an AI ghostwriter for X and LinkedIn: a queue, evergreen posts that recycle, auto-plugs and analytics, priced from $19 to $97 per month, which is $228 to $1,164 per year. `grai` ($69 once, Founder Edition, or $149 Agency) is a local-first HTML5 voice workbench that measures your cadence and enforces a `CV >= 0.32` floor before a post goes anywhere.

### TL;DR Comparison

| Option | Best For | Starting Price | Key Difference |
| :--- | :--- | :--- | :--- |
| **`grai`** (Founder) | Keeping a measured personal cadence across every draft, with a deterministic gate before publishing. | **$69 once** (AI model/API usage separate if used) | 622 KB local workbench. Voice DNA from 5 to 20 samples, 6 structural rules, `CV >= 0.32` floor, no social account connection. |
| **Hypefury** | Creators who post often on X and LinkedIn and want a queue, evergreen recycling and auto-plugs. | **$19/month** (annual billing, entry tier) | Hosted scheduler plus an AI ghostwriter that drafts in a generic voice tuned by prompts, not by a measured profile. |

## 1. Scheduling Plus Drafting vs. Measuring the Voice

Hypefury bundles two jobs. The scheduler handles the calendar: a queue, evergreen posts that recycle, auto-plugs that resurface an offer, and analytics. The AI ghostwriter handles the blank page: it drafts a post from a prompt and a short description of your style.

`grai` handles one job and measures it. It reads 5 to 20 of your real posts, extracts a quantitative profile, and refuses a draft that breaks the six structural rules or drops below the cadence floor. The output is a score, a CV value, and the exact spans that failed.

Those are complementary, not equivalent. A scheduler can publish a flat draft on time, and an AI ghostwriter can produce a fluent paragraph that sounds like every other Hypefury user. Neither one can tell you that your sentence lengths collapsed.

## 2. Where Hypefury Wins vs. Where grai Wins

### Where Hypefury Wins

- **Queue and evergreen:** one post can recycle for months without extra work.
- **Auto-plugs:** an offer resurfaces automatically under a chosen post.
- **X and LinkedIn in one place:** a single calendar for both networks.
- **Draft assistance:** the AI ghostwriter removes the blank page for a quick post.

### Where grai Wins

- **Measured, not prompted:** the profile comes from 5 to 20 real samples, so the gate compares the draft to your numbers, not to a paraphrase of your style.
- **Deterministic gate:** six regex rules and a `CV >= 0.32` floor, computed in JavaScript, with flagged spans and targeted repair.
- **One-time price:** $69 once against $228 to $1,164 per year, and the workbench keeps running after the year ends.
- **No social OAuth:** `grai` holds no X or LinkedIn token and never acts on your account.

## 3. Side-by-Side Technical and Commercial Matrix

| Criterion | grai (Founder $69 / Agency $149) | Hypefury ($19 to $97 per month) |
| :--- | :--- | :--- |
| Pricing model | **$69 once** (Founder) or **$149 once** (Agency) | **$19 to $97 per month**, billed monthly or annually |
| Primary job | Voice extraction and deterministic cadence verification | Scheduling, evergreen recycling and AI-assisted drafting |
| Voice model | Quantitative profile from 5 to 20 samples, stored in your browser | AI drafting guided by prompt instructions |
| Cadence verification | 6 regex rules + `CV >= 0.32` floor, with flagged spans | No deterministic sentence-rhythm gate |
| Scheduling | None. `grai` writes and audits, nothing else | Queue, evergreen and auto-plugs across X and LinkedIn |
| What happens if you stop paying | You keep `grai.html` and your `.grai` files permanently | Queue, analytics and recycling stop |

## 5. Privacy and Data Flow Boundary

- **Shipped Pre-Built Kit (`grai.html`):** Ships with a Content Security Policy (`default-src 'none'; style-src 'unsafe-inline'; font-src data:; img-src data:; script-src 'unsafe-inline'; connect-src 'none'; object-src 'none'; base-uri 'none'`) that allows inline styles and inline scripts (plus `data:` fonts and images) while blocking direct API connections (`connect-src 'none'`) from the page. Out of the box, it runs in Copy-Paste mode.
- **Browser Storage:** Voice profiles and writing samples (along with drafts) are stored in your browser's `localStorage` when available. If your browser settings or private-browsing mode block `localStorage` on local `file://` pages, `grai` falls back to in-memory session storage (`memStorage`), which lasts until the tab closes. Export a `.grai` backup file to save your profiles permanently to disk.
- **When data leaves your machine:** (1) when you paste and submit a prompt into Claude or ChatGPT (or Gemini) in Copy-Paste mode, (2) when you run a custom source build with BYOK enabled and send a prompt to your selected API provider, or (3) when you export and share a `.grai` file or PDF Dossier yourself. Hypefury stores drafts, the queue and the account connections in its cloud by design.

## 6. Verdict: Which Should You Choose?

**Choose Hypefury ($19 to $97/month) if:** volume and consistency are the problem. You want a queue, evergreen recycling and an auto-plug doing the distribution work.

**Choose grai ($69 once) if:** the text is the problem, and another scheduling layer will not fix it. A scheduler cannot tell you that every sentence is twelve words long, and an AI ghostwriter will not measure it either.

**Use both if:** you gate in grai, then paste into Hypefury. Nothing overlaps.
