PlainpaperPlainpaper: The AI Marketing Canvas That Brings Your Own Agent
Most AI marketing tools hand you a better draft. Plainpaper hands the agent the whole campaign — research through publish — and keeps you in the approval seat. The board persists outside the chat window, so campaign context lives in the board itself rather than a conversation thread you have to keep open, and the agent picks up where it left off on the next session. It is built for solo marketers and small teams who want end-to-end AI-powered campaign execution without handing credentials to a third-party platform.

Key Takeaways
- 1Seven-day free trial, no credit card required; the free tier after trial keeps one active board with full agent connection — a genuine ongoing working tier, not just a holding state
- 2BYOA (bring your own agent) — Claude, ChatGPT, Cursor, or any MCP-compatible client connects to the board; no proprietary LLM, so your model choice and inference costs stay yours
- 3Typed card system (Brief, Audience, Insight, Email, Creative, Result) keeps campaign output structured and reviewable, not buried in a chat log
- 4Approval gates on every publish action — Plainpaper never holds your credentials; the agent calls each platform via its own MCP server or API only after you approve
- 5Board persists across sessions — campaign context (briefs, audiences, past results) lives on the board; the agent reads it and picks up without you replaying history
What Plainpaper Is — and What It Isn't
Most AI marketing tools are AI writing tools — they generate a first draft, and then the human assembles, emails, and posts. Plainpaper takes a different approach: it is a shared visual board where an AI agent runs the entire campaign workflow, from research and audience analysis through email creation and ad creative, with the human in the approval seat at each execution step. The important architectural distinction: Plainpaper is the workspace and approval layer, not the integration layer. When you approve an email card, the agent — not Plainpaper — calls Mailchimp or Klaviyo via that platform's own MCP server or API and executes the send. Plainpaper holds no credentials and does not connect to those platforms itself. The typed cards (Brief, Audience, Insight, Email, Creative, Result) live on the persistent board with statuses, comments, and approval gates. That boundary between workspace and execution is the whole security architecture.

The BYOA Model and Persistent Board Memory
The standard AI marketing tool has a proprietary LLM baked in — the team running the tool decides which model generates your email copy, your ad creative, and your campaign strategy. Plainpaper inverts this: it is the structured workspace the agent operates within, not the agent itself. Connect Claude through Claude Desktop, ChatGPT, Cursor, or any MCP-compatible client, and that model runs your marketing board. The model's capabilities — and your inference cost relationship — stay yours. The board persistence is where this gets practically useful. In most AI marketing workflows, context lives in a chat thread. Close the window and you're starting over, or copy-pasting campaign briefs into a new session. On Plainpaper, the board is the memory: Brief cards, audience cards, past campaign results, and brand guidelines — all visible to the agent on reconnect. The agent reads the board and picks up where it left off. The brand guidelines layer includes a 'Prevent AI language' preset — a tone-of-voice setting that tells the agent to avoid AI-sounding phrasings. For teams worried about copy that reads as generated, this is a live feature, not a roadmap item.
Who Gets the Most From Plainpaper
Solo marketers and founders
One agent, one board, full campaign execution without a team — research, copy, creative, and publish in a single workspace
E-commerce teams (Shopify + Klaviyo + Meta Ads)
All three core e-commerce platforms are in the compatible stack; the agent can run a product-launch campaign end-to-end from the same board
Small agency teams
Scale tier supports 10 users across 5 workspaces with 30 boards per workspace; multi-client campaign management is viable on a single account
Non-technical marketing managers
The canvas and card UI are approachable; connecting an MCP client is a one-time configuration comparable to a browser extension install — not ongoing maintenance, but a setup step nonetheless
Large enterprise marketing teams
Business tier caps at 25 users and 15 workspaces with no SSO or enterprise auth; better suited to mid-market than enterprise rollouts
Pricing and Getting Started
Plainpaper's free tier gives you one active board with full agent connection after the 7-day trial — not a locked demo, but a genuine working tier for a single ongoing campaign. The trial itself is no-credit-card and 7 days, which is a tight window for a product whose value compounds as campaign context accumulates on the board. Starter at €29/mo (€290/yr) gives 1 workspace, 1 user, and up to 20 boards — the practical floor for anyone running more than one campaign at a time. Scale at €79/mo (€790/yr) expands to 5 workspaces, 10 users, and up to 30 boards per workspace. Business at €149/mo (€1,490/yr) lifts the ceiling to 15 workspaces, 25 users, and unlimited boards. Pricing is in euros — buyers outside the EU will see the current exchange rate applied at checkout. For the MCP setup step: Plainpaper's documentation walks through the Claude Desktop connection step-by-step; the one-time agent configuration is comparable to installing a browser extension, not an ongoing technical task. The 13 official playbook templates in-product give new users structured campaign frameworks — email launches, ad campaigns, audience research — so day one starts with a brief, not a blank canvas.
Launchstag Editorial Ratings
Canvas and typed cards are intuitive for marketers; the one-time MCP agent setup is a browser-extension-level task, not ongoing friction — daily use is chat-driven and approval-gated
BYOA means no hidden LLM markup; 7-day trial is tight for a product that compounds with campaign history; pricing in euros adds a conversion step for non-EU buyers
BYOA + MCP-native structured board + persistent campaign memory + no-credentials architecture + approval gates is a genuinely novel combination in AI marketing tooling
Card types, 13 playbooks, 7 agent-compatible platforms, end-to-end approval-to-publish — comprehensive for a product at this stage; Business tier caps at 25 users which may constrain larger team deployments
Playbook templates and a no-credit-card trial provide a structured on-ramp; as a newer product, documentation and community resources are still developing
Best For
Solo marketers, e-commerce teams, and small agencies who want an AI agent to run full marketing campaign workflows — from research and audience briefs through email and ad creative to publish — with human approval gates and no third-party credential storage.
Not Ideal For
Enterprise marketing teams needing SSO, unlimited users, or more than 15 workspaces — Plainpaper's current tier structure is built for solo and small-team use. Teams wanting a fully one-click agent setup with no initial configuration should expect a one-time MCP connection step before the first session.
Pros
- + BYOA model — connect Claude, ChatGPT, Cursor, or any MCP-compatible agent; no proprietary LLM lock-in and no hidden inference markup
- + Persistent board memory — campaign context (briefs, audiences, brand guidelines, past results) lives on the board so the agent picks up where it left off without replaying history
- + Typed card system (Brief, Audience, Insight, Email, Creative, Result) keeps campaign output structured and approachable, not buried in a chat thread
- + Approval gates on every action — nothing sends or publishes without human sign-off; the agent calls platforms via their own MCP servers or APIs, Plainpaper holds no credentials
- + 'Prevent AI language' brand guidelines preset — a tone-of-voice setting that actively steers the agent away from AI-sounding phrasings in campaign copy
- + Seven agent-compatible platforms covering common e-commerce and email stacks: Mailchimp, Brevo, ActiveCampaign, Klaviyo, Shopify, Meta Ads, and Canva
- + 13 official playbook templates give new users structured campaign frameworks on day one — email launches, ad campaigns, audience research, product launches, and more
Cons
- − Free tier after the 7-day trial is limited to one active board — teams who want to run campaigns across multiple product lines or clients simultaneously before committing should plan for Starter (€29/mo)
- − Connecting an AI agent requires a one-time MCP client configuration (Claude Desktop, ChatGPT, or Cursor) — not ongoing maintenance, but a setup step that may need IT assistance for non-technical marketers
- − Pricing is in euros — buyers outside the EU will see currency conversion at checkout; annual plans (€290–€1,490/yr) can reduce the conversion frequency
Verdict
Plainpaper's thesis is that marketing campaign execution — not just draft generation — is what AI should be handling, and that the agent should operate within a structured workspace that persists between sessions rather than a conversation thread that resets. The BYOA model means you're not locked into one LLM vendor; the approval gate means you stay in control of what actually publishes; and the no-credentials architecture means Plainpaper never has direct access to your email lists or ad spend. The 'Prevent AI language' brand preset addresses the most common objection head-on: the copy doesn't have to sound like AI. For solo marketers and e-commerce teams running regular campaign workflows, those constraints together are the product's real value proposition. Start the 7-day free trial at plainpaper.io — no credit card required. Pick one of the 13 official playbook templates to structure your first campaign brief, then connect your preferred MCP client (Claude Desktop, ChatGPT, or Cursor) to run it. If the board's persistent memory and the integration-approval workflow fit your team's rhythm, Starter at €29/mo is the path forward.
Frequently Asked Questions
Do I need to bring my own AI model to use Plainpaper?⌄
Yes — Plainpaper uses the BYOA (bring your own agent) model. You connect Claude via Claude Desktop, ChatGPT, Cursor, or any MCP-compatible client. There is no proprietary LLM in the platform; your inference costs stay with the provider you already use, and Plainpaper applies no markup on them.
Does Plainpaper store my email or ad platform credentials?⌄
No. Plainpaper never holds your credentials. When you approve a card, the agent — not Plainpaper — calls the relevant platform (Mailchimp, Klaviyo, Meta Ads, etc.) via that platform's own MCP server or API and executes the action. Plainpaper is the workspace and approval layer; the agent is the executor.
What happens to my boards after the 7-day trial?⌄
After the trial, the free tier keeps one active board with full agent connection — a genuine ongoing working tier for a single campaign, not a locked demo. If you need more boards or multiple workspaces, Starter at €29/mo (€290/yr) gives up to 20 boards on one workspace.
Which platforms does Plainpaper work with?⌄
Plainpaper's workspace is designed for campaigns using Mailchimp, Brevo, ActiveCampaign, Klaviyo, Shopify, Meta Ads, and Canva. The agent connects to those platforms via their own MCP servers or APIs after you approve the relevant card — Plainpaper itself holds no credentials and does not connect to those platforms directly.
How is Plainpaper different from an AI writing tool like Jasper or Notion AI?⌄
AI writing tools generate copy — you still assemble, schedule, and publish manually. Plainpaper's agent runs the entire workflow: research cards, audience briefs, email creation, ad creative, and publishing through connected platform integrations. The board also holds campaign context across sessions, so the agent doesn't start from scratch each time. And with the 'Prevent AI language' brand preset, the output actively avoids AI-sounding phrasing.
