The short version
A blank AI chat drafts an email in seconds, then loses it the moment you close the tab: no board to reopen, no record of what was approved, nothing a teammate can see. A whiteboard like Miro, FigJam or Milanote keeps the plan visible, but nothing on it is written by an agent, so you are still typing every card yourself. A doc holds copy well and holds nothing else: no rendered email, no ad staged in a real placement, no connection back to the platform that sends it.
Plainpaper is built to be the one place that does all three at once. An AI agent, Claude or ChatGPT or any MCP client, drafts the campaign directly onto a persistent, shareable board as typed cards you review and approve before anything ships.
Side by side
| A blank chat | A whiteboard | A doc | Plainpaper | |
|---|---|---|---|---|
| Holds the campaign after you close it | No | Yes | Yes | Yes |
| An agent writes the content directly | Yes | No | No | Yes |
| Rendered email preview, not just copy | No | No | No | Yes |
| Ad creative staged in a platform mockup | No | Partly | No | Yes |
| Draft versus approved is enforced | No | No | No | Yes |
| A teammate can see the plan | No | Yes | Yes | Yes |
| Connects to your ESP or ad platform | Partly | No | No | Yes |
What a blank chat is genuinely better at
Speed on a single artefact. If you need one subject line, one paragraph rewritten, one idea pressure-tested, opening Claude and typing is faster than any tool with a board in it, and adding structure to that would only slow you down. Plenty of good marketing work never needs to leave a chat.
The point it breaks is the second session. A campaign is not one artefact, it is a brief, an audience, a strategy, a set of emails and creative, and a result measured back against the goal. A chat holds that only as long as the window is open, and the reasoning behind an approved decision disappears with it.
Where a whiteboard stops
Miro, FigJam and Milanote solve visibility properly: the plan is spatial, shareable and easy to reason about, which is exactly why marketers reach for them. What they do not have is an agent that writes into them. The board is a surface for what you have already decided and typed, so the work of producing the campaign stays entirely with you.
Where a doc stops
A doc is the natural home for copy and a poor home for everything a campaign needs after the copy exists. It cannot show the email as it will actually render, cannot stage an ad in an Instagram or TikTok frame so you can judge it in place, and has no idea which version was approved and which was a draft someone left in a comment.
When Plainpaper is the wrong choice
If you are drafting one email a month, this is more structure than the job needs, and a chat window will serve you better. If your team has no interest in an approval step, most of what Plainpaper enforces will feel like friction rather than safety. And if you want a tool that sends the campaign itself, this is not that: execution stays in your own platform, reached through its own connector, after you approve the card.
Frequently asked questions
Why not just use ChatGPT or Claude on their own?
For a single email, do. The chat drafts it faster than any tool with a UI. What a chat cannot do is hold the campaign: close the tab and the plan, the reasoning and the approvals are gone, and a teammate has no way to see any of it. Plainpaper gives the same agent somewhere durable to put the work.
How is this different from Miro, FigJam or Milanote?
Those keep things visible, which is genuinely useful, but nothing on the board is written by an agent. You still type every card yourself. On a Plainpaper board the agent creates and updates the cards directly, and every one of them arrives as a draft you approve.
Could I not just use a Google Doc?
A doc holds copy well. It does not hold a rendered email preview, an ad staged in a platform mockup, or a connection back to Mailchimp or Meta, and it has no notion of approved versus draft. Those four are most of what a campaign needs after the words exist.
Does Plainpaper replace my email or ads platform?
No. It is the place the work is planned, drafted and approved. Execution stays in Klaviyo, Brevo, Mailchimp, Meta or whatever you already use, reached through that platform's own connector, and only after you approve the card.
Try it on one campaign
The comparison stops being abstract on the first board. Brief a real campaign, let your agent draft it, and see whether having the plan survive the session is worth the structure.
