ScriptGrain vs VoiceMoat

ScriptGrain publishes what VoiceMoat keeps to itself: the attributes a voice is measured on and the method behind the score. Both score drafts against a trained voice; only one shows its working, and only one is on every plan.

The actual difference

VoiceMoat scores drafts against a trained voice but does not say what it measures or how the 0 to 100 is computed. ScriptGrain measures 45 named attributes across eight layers, publishes the scoring method with its weights and tolerances, returns the per-feature deltas with every score, and puts the API and MCP server on every plan including Free. It writes sixteen content types, not posts and replies only, and it does not post anywhere for you.

VoiceMoat's paid plans start at $35 a month and the MCP connector needs Pro at $69; profile slots cost extra from $15. ScriptGrain's Writer plan is £12 a month with the connector included, and the free plan measures one voice with no card.

ScriptGrain is not a replacement for the assistant you already use. It measures your voice from writing you have published and hands that profile to ChatGPT, Claude, Muse or any MCP client through its connector, then scores every draft against it. ScriptGrain makes your AI better at being you.

Where VoiceMoat is stronger

A social media writing and posting tool for X and LinkedIn: trained voice, drafts, replies, scheduling, analytics, an MCP connector on Pro and up, and a 0 to 100 voice score against your trained voice.

If your writing lives on X and LinkedIn and you want drafting, replies, scheduling and posting in one place, VoiceMoat is that product and ScriptGrain is not; ScriptGrain measures and writes, it does not publish to a network.

Does VoiceMoat learn my writing voice?

You train a voice profile from your posts; the MCP tool describes it as persona, tone markers, traits and never-say phrases. Drafts and replies are scored 0 to 100 against it and the tool names what is off. The attribute list and the scoring method are not published. ScriptGrain instead measures 45 style attributes from writing you have already published, and scores every draft against that measured profile.
