Comparison 14 // Local Voice Gate vs. Cloud Content Generator.
grai ($69 once, Founder Edition, or $149 Agency) is a local-first HTML5 workbench that measures your existing voice and blocks the drafts that break it.
| Option | Best For | Starting Price | Key Difference |
|---|---|---|---|
grai (Founder) |
Keeping a measured personal cadence while drafting, 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 account. |
| Writesonic | Teams that need a high volume of SEO and social drafts from a template library. | $16 per month (annual billing, entry tier) | Cloud generator with SEO briefs, templates and a brand voice preset. Volume is the product, not verification. |
Writesonic is built to produce. You pick a template, give it a topic and a target keyword, and receive a draft that is already structured for search or for LinkedIn. The value is throughput and a starting point that beats a blank page.
grai is built to verify. It extracts a numeric profile from your real writing, drafts in three editorial galleys, then audits the result against six structural rules and a burstiness floor. It will not produce a hundred articles, and it is not trying to.
The failure mode of a generator is sameness. Every customer runs a similar prompt against a similar model, so the output converges on a recognizable register. A measured profile is the cheapest exit.

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. Writesonic generates and stores the draft in its cloud by design.Choose Writesonic ($16 to $79 per month) if: volume is the problem. You need SEO drafts and social variants faster than a person can write them.
Choose grai ($69 once) if: the drafts already exist, they all sound alike, and another generator would only add to the pile. A measured gate tells you which draft is publishable.
Use both if: Writesonic produces the first draft and grai audits it before publishing. Run the gate before you publish.
