# ScriptGrain vs My Writing Twin · an honest comparison > How ScriptGrain and My Writing Twin differ on brand voice, and what each costs. My Writing Twin pricing checked 30 July 2026. Canonical: https://scriptgrain.com/vs/my-writing-twin # ScriptGrain vs My Writing Twin ScriptGrain measures your style and then writes with it, checking every draft against the profile. My Writing Twin, the fairest comparison here, measures too, but hands you a report rather than a writing tool. ## The actual difference Both measure style rather than describe it, which makes this the fairest comparison here. The difference is what you get: My Writing Twin hands you a prompt to take elsewhere; ScriptGrain keeps the profile live inside a generator that drafts, scores each draft against your voice, and lets you correct the profile as your writing changes. My Writing Twin is a one-off $49-$249 for a profile you take away. ScriptGrain is £12-£299/mo and includes the generation. If you only want the prompt, theirs is cheaper; if you want the writing done and checked, the comparison is not really price against price. · ScriptGrain · My Writing Twin Entry price · £12/mo (Writer, 1 voice profile) · $49 one-off (Starter) Free tier · Yes, See your own voice profile.
