Comparison 07 // Local Voice Ownership vs. Cloud Publishing Calendar.
grai ($69 once, Founder Edition, or $149 Agency) is a local-first HTML5 voice workbench that never connects to a social account. It profiles your Voice DNA locally, shapes the argument in three editorial galleys, and audits every draft against 6 structural regex rules plus a mathematical burstiness floor (CV >= 0.32).
| Option | Best For | Starting Price | Key Difference |
|---|---|---|---|
grai (Founder) |
Making the text itself sound like you, before it reaches any scheduler. | $69 once (AI model/API usage separate if used) | Offline 622 KB HTML5 workbench. Voice DNA, 3-galley Writing Desk and the 6-rule cadence gate run in your browser. No social account connection. |
| Typefully | Writing threads and shipping a consistent posting calendar on X and LinkedIn. | $12.50/month (annual billing, entry tier) | Hosted cloud composer, queue and analytics, with account OAuth for publishing. |
Typefully is built around distribution. You write in a cloud composer, arrange a queue, schedule the week across X and LinkedIn, and read the analytics in the same dashboard. The value is rhythm of publishing and the fact that you never open the social app to post.
grai is built around the text. It extracts a quantitative profile from your real samples, reshapes the premise in three galleys, and runs a deterministic audit before anything is published. It does not schedule, does not queue, and never asks for a social account.
The order matters. A post scheduled at the perfect hour with flat, generic cadence still reads as filler. A post with your real rhythm can be published manually in ten seconds.
grai holds no token for X or LinkedIn and never acts on your account, so no third-party automation flag can reach you.CV >= 0.32): audits sentence-length burstiness and 6 structural rules in JavaScript, highlights the matching spans and offers targeted repair.| Criterion | grai (Founder $69 / Agency $149) | Typefully ($12.50 to $29 per month) |

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.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..grai file or PDF Dossier yourself. Typefully, by contrast, stores drafts and the account connection in its cloud by design.Choose Typefully ($12.50 to $29/month) if: you publish threads on a schedule and want a queue plus analytics without opening the social app.
Choose grai ($69 once) if: the problem is the writing. A scheduling tool cannot tell you that your sentences are all the same length, and that is the tell readers notice first.
Use both if: you draft and audit in grai, then paste the audited text into Typefully and let it publish on schedule. The two do not overlap at all.
