ScriptGrain vs Noren
ScriptGrain measures your voice as 45 attributes and scores every draft against them. Noren builds a portable, human-editable profile designed to travel between Claude, GPT and Gemini.
The actual difference
Noren produces a readable profile you take to whichever model you like. ScriptGrain measures 45 attributes and then scores every draft against that measurement, so the profile is not only a description you carry around but a target the output is held to and graded on.
Noren offers a free tier and does not display paid pricing on its main page, so we are not going to guess at it. ScriptGrain publishes its plans in full: free, £12/mo, £29/mo, £99/mo.
| ScriptGrain | Noren | |
|---|---|---|
| Entry price | £12/mo (Writer, 1 voice profile) | Not published (free tier, no card) |

| Voices on entry plan | 1 (3 on Operator, £29/mo) | Not published |
| How the voice is built | 45 measured style attributes, extracted from writing you have already published | You "give Noren examples of things you have already written" and it captures "the words you reach for, how long your sentences tend to be, how you make a point, what you avoid". Profiles also record anti-patterns, the words you would never use, and the profile itself is readable, editable and exportable for use with different models. |

Where Noren is stronger
"AI that writes like you, not like ChatGPT." A portable voice-profile layer that works across Claude, GPT and Gemini via a desktop app, browser studio and Chrome extension.
- The profile is portable and human-readable, you can read it, edit it, export it, and carry it to another model
- Anti-patterns are a genuinely good idea: recording what you would never write is as identifying as what you do
- Works where you already are, across multiple LLMs, rather than asking you to move your writing into one app
If model portability matters to you, you want one voice profile that follows you to Claude today and something else next year, Noren is designed for exactly that, and an editable profile you own outright is a real advantage.
