# grai vs. Copy.ai: Local Voice Harness vs. Cloud GTM Workflow Templates (2026) > **Last verified against public pricing and vendor documentation:** 2026-10-29 > **Canonical URL:** https://grai.page/vs/copyai **Direct Answer:** Copy.ai ($49 per month, about $588 per year) is a cloud GTM platform: workflow templates for outbound sequences, account research, content briefs and sales enablement, with team seats and integrations. `grai` ($69 once Founder, $149 Agency) is a local voice harness: it extracts Voice DNA from 5 to 20 real samples, enforces the 6 syntactic rules plus a `CV >= 0.32` floor in your browser, and prints an A4 Client Voice DNA Dossier with a SHA-256 hash. ### TL;DR Comparison | Option | Best For | Starting Price | Key Difference | | :--- | :--- | :--- | :--- | | **`grai`** (Founder) | Keeping one specific human voice intact across drafts, with a mathematical gate before publishing. | **$69 once** (AI model/API usage separate if used) | 622 KB local HTML5 harness. Voice DNA, 6-rule gate, `CV >= 0.32` floor and A4 SHA-256 Dossiers. | | **Copy.ai** | GTM teams that need repeatable workflows and templates across outbound, research and content. | **$49/month** (about $588 per year on monthly billing) | Cloud workflow platform with templates, seats and integrations; the voice layer is a preset, not a measurement. | --- ## 1. Workflow Automation vs. Voice Measurement Copy.ai is a GTM workflow product. It gives a revenue team repeatable jobs: build a prospect list, research accounts, draft outbound sequences, generate a content brief. The output is volume and consistency of process, and the value shows up when five people need to produce the same class of asset every week. `grai` does one job and measures it. It reads your real writing, extracts the quantitative profile, and refuses to let a draft drift into a flat, generic cadence. There are no workflows, no seats and no campaign templates, because the problem it solves starts after the workflow produced a draft. The honest split: if the bottleneck is process, Copy.ai addresses it. If the bottleneck is that every output sounds like the same model, a workflow suite cannot fix it, because a preset is not a measurement. --- ## 2. Where Copy.ai Wins vs. Where grai Wins ### Where Copy.ai Wins - **GTM workflows:** repeatable sequences for outbound, account research and content briefs. - **Team seats and shared assets:** one workspace where several people run the same playbook. - **Integrations:** connections to the CRM and sales stack a revenue team already runs. - **Volume:** many assets per week from a small team, with a consistent structure. ### Where grai Wins - **Quantitative Voice DNA:** a measured profile from 5 to 20 real samples, stored locally, not a brand-voice preset typed into a form. - **Deterministic gate:** 6 syntactic rules plus a `CV >= 0.32` burstiness floor, computed in JavaScript, with flagged spans and targeted repair. - **One-time price:** $69 once against $588 per year, and the files keep working after the year ends. - **Client proof ($149 Agency):** up to 25 isolated client profiles and a one-page A4 Client Voice DNA Dossier signed with a SHA-256 hash. --- ## 3. Side-by-Side Technical and Commercial Matrix | Criterion | grai (Founder $69 / Agency $149) | Copy.ai ($49 per month) | | :--- | :--- | :--- | | Pricing model | **$69 once** (Founder) or **$149 once** (Agency) | **$49 per month**, about $588 over 12 months and $1,176 over 24 | | Primary job | Voice extraction and deterministic cadence verification | GTM workflow automation and templated content production | | Voice model | Quantitative profile from 5 to 20 samples, stored in your browser | Brand voice preset configured inside the workspace | | Cadence verification | 6 regex rules + `CV >= 0.32` floor, with flagged spans | No deterministic sentence-rhythm gate | | Team seats | One licence per machine; 25 client profiles in Agency | Seat-based team workspace | | What happens if you stop paying | You keep `grai.html` and your `.grai` files permanently | Workflows and workspace access stop | --- ## 4. 12-Month and 24-Month Total Cost Comparison | Setup | Month 1 | 12-Month Total | 24-Month Total | What Is Included | | :--- | :--- | :--- | :--- | :--- | | **Copy.ai** (monthly billing) | $49 | $588 | $1,176 | Cloud workflow templates, seats and integrations | | **Copy.ai, five seats** | $245 | $2,940 | $5,880 | The realistic configuration for a GTM team | | **`grai` Founder + existing AI subscription** | $89 ($69 + $20) | $309 ($69 + $240) | $549 ($69 + $480) | Local Voice DNA + Cadence Gate + the model you already use | | **`grai` Agency Edition** (one-time) | $149 | $149 | $149 | 25 client profiles + A4 SHA-256 Dossiers, forever | --- ## 5. Privacy and Data Flow Boundary - **Shipped Pre-Built Kit (`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. - **Browser Storage:** Voice profiles and writing samples (along with drafts) are stored in your browser's `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. - **When data leaves your machine:** (1) when you paste and submit a prompt into Claude or ChatGPT (or Gemini) in Copy-Paste mode, (2) when you run a custom source build with BYOK enabled and send a prompt to your selected API provider, or (3) when you export and share a `.grai` file or PDF Dossier yourself. Copy.ai, by contrast, runs workflows and stores their assets in its cloud by design. --- ## 6. Verdict: Which Should You Choose? **Choose Copy.ai ($49/month) if:** your team needs repeatable GTM workflows, shared seats and integrations, and the problem is process volume. **Choose grai ($69 once) if:** the problem is that the copy reads like the model wrote it. One measured profile and a deterministic gate solve that; another template does not. **Use both if:** the team runs the workflow in Copy.ai and the client-facing output still passes through grai before delivery. That is the Agency Edition use case. --- ## Frequently Asked Questions ### Is grai a replacement for Copy.ai? No. Copy.ai is a cloud GTM workflow platform with templates, seats and integrations. grai is a local measurement and enforcement layer for one voice. It will not build prospect lists, run outbound sequences or manage a team workspace, because that is a different product. ### How does the cost compare over two years? Copy.ai at $49 per month costs $1,176 over 24 months for one seat and $5,880 for five seats. grai Founder is $69 once and the Agency Edition is $149 once, with no renewal. ### Does grai work with the AI subscription I already pay for? Yes. The shipped kit runs in Copy-Paste mode, so you paste a prompt into Claude, ChatGPT or Gemini and paste the result back for local verification. A custom source build can call a BYOK provider or a local Ollama model. **Checkout:** [Founder Edition ($69 once)](https://payhip.com/b/5pXfN) | [Agency Edition ($149 once)](https://payhip.com/b/QVIBp)
