# ARNA-01 — AI Brand Editor

*Brand-voice copy editor across all surfaces*

ARNA edits marketing copy against your brand-voice baseline — web, ads, social, sales — with the brand-voice samples your editor has approved frozen at deployment.

## Why it matters

Jasper Pro tops out as a writing assistant; the actual brand-voice agentic features live in Business tier behind a sales call. Writer's Knowledge Graph and Agent Builder are Enterprise-only. ARNA runs the brand-voice editor surface at $1,000/mo flat with the voice baseline frozen at deployment.

## Capabilities

- Edits draft copy against your editor's brand-voice samples
- Surfaces voice drift candidates per surface (web, ads, social, sales)
- Flags banned-word use per your editor's published rules
- Logs every edit with the brand-voice sample that informed it
- Maintains a per-surface voice-drift digest weekly

## The edge

ARNA refuses to ship if the brand-voice fidelity score falls below the threshold your editor sets at deployment. The pencil pauses; your editor takes the call.

## The hook

Every Friday ARNA ships a brand-voice drift report by surface: which surfaces drift most, which writers got pushed back the most, which voice samples no longer match what's actually being shipped.

## Tools and integrations

- Slack
- Notion
- Google Docs
- Figma

## Evidence

- Operates under the four-tier Fidelic constitution; the autonomy ceiling is 'edit only'
- EvalOps suite covers brand-voice fidelity, banned-word detection, and false-positive rate
- Inherits new base models and new agent skills automatically — pushed to every Fidelic agent the moment they ship. Same shape as a SaaS update; no upgrade purchase, no version pinning.

## Safeguards

ARNA will not change the brand-voice baseline. Only your editor can update the voice samples.

ARNA will not originate positioning or campaign concepts. The agent edits, it does not invent.

ARNA will not approve copy for ship below the brand-voice fidelity threshold the editor has set.

## Worst-case behavior

ARNA flags low confidence on voice fit rather than approving copy that drifts. The editor decides whether to ship anyway.

## Day 1 / Week 1 / Month 1

- **Day 1:** Provisioned. Editor approves brand-voice samples and banned-word list.
- **Week 1:** First Friday voice-drift digest ships. Per-surface fidelity baseline established.
- **Month 1:** Multi-surface coverage active. Voice-drift trend reported weekly.

## 90-day success criterion

Brand-voice fidelity score at the level your editor defines, sustained across all shipped copy for three weeks.

## Integrations / supervision required

Read access to your CMS, draft channels, and brand-voice samples. Slack for digests.

## Resume

**Background.** Brand-voice editing is the marketing surface where AI tools have over-promised most loudly. Jasper and Writer claim to maintain voice; the actual voice-agent capability lives in their highest enterprise tiers. ARNA runs flat-rate, with the voice baseline frozen at deployment.

**Methodology.**
- Reads brand-voice samples and the last 90 days of approved copy before editing anything
- Routes against the four-tier constitution: autonomous on edit suggestions, review-required on banned-word patches, escalate on positioning ambiguity, refuse on voice-baseline changes
- Logs every edit with the voice sample reference

**Evals.** EvalOps suite covers brand-voice fidelity, banned-word detection accuracy, and false-positive rate on edit suggestions.

**Operating record.** First-cohort deployments scheduled May–June 2026. Operating-record metrics publish with the first quarterly cohort review.
