An AI marketing assistant writes and plans your posts, captions and emails so you spend less time on a blank page. For most creators the choice is between a general chat assistant (ChatGPT or Claude), a marketing writer (Jasper or Copy.ai), a social scheduler with AI built in (Buffer or Later), or AI inside the platform where you sell. On WithMe, Margo plans and writes your social posts and emails, and Otto answers questions about your hub and proposes changes for you to approve.
WithMe is $25 per month billed annually (UK £25), with a 14-day trial and 0% WithMe commission. Stripe and PayPal fees still apply. More than 8,000 creators use it. AI credits are optional and purchased separately from your Hub subscription.
What does an AI marketing assistant do?
- Turns one idea into captions, hooks and post variations.
- Plans a week or a month of posts around a launch.
- Drafts emails, from a welcome sequence to a sales email.
- Schedules posts and publishes them to your accounts.
- Reads what worked last week and suggests what to post next.
Are ChatGPT and Claude enough?
For writing, often yes. Both have free plans. Claude Pro is $20 a month, or $17 a month billed yearly ($200 up front), on Anthropic's pricing page (checked 11 November 2026). OpenAI lists its paid ChatGPT plans (Go, Plus and Pro) on its own pricing page, and the price depends on your country, so check it there before you subscribe.
The gap is everything around the writing. A chat assistant does not know your products, prices or sales unless you paste them in, it does not keep a content calendar, and it cannot post for you.
What do Jasper and Copy.ai cost?
Jasper Pro is $69 per seat a month, or $59 per seat a month billed annually, for one seat, with brand voices, marketing agents, image generation and a 7-day free trial. Business is priced on request (checked 11 November 2026).
Copy.ai's Chat plan is $29 a month, or $24 a month billed annually, for up to 5 seats with unlimited chat words. Its workflow plans start at $1,000 a month with 20,000 workflow credits (checked 11 November 2026).
Both are built for marketing teams. A solo creator who mostly writes captions and emails will usually get the same value from a general chat assistant.
What about Buffer and Later?
Buffer's free plan covers up to 3 channels and 10 scheduled posts per channel at a time, and includes its AI Assistant. Essentials is $5 a month per channel billed yearly ($60 a year per channel), and Team is $10 a month per channel billed yearly (checked 11 November 2026).
Later's yearly-billed plans are Starter at $18.75 a month with 5 AI credits a month, Growth at $37.50 with 50 AI credits, and Scale at $82.50 with 100 AI credits, with a 14-day free trial (checked 11 November 2026).
Schedulers are strong on the calendar and on posting to many networks. Their AI writes captions, but it does not know what you sell or which of your products earns the most.
What does WithMe's Margo do?
Margo is the marketing agent on WithMe's AI team. She works in her own app inside AI Agents (AI Team on your phone):
- Plans a content calendar and writes posts and captions for each platform.
- Makes carousel and story slides, with images you can swap for your own photos.
- Publishes scheduled posts to Instagram, LinkedIn and Threads once you connect them. Reels and stories are not posted for you: she reminds you to post those yourself.
- Writes emails. An email she drafts for your list is sent through WithMe's email only after you approve it.
- Reviews how your posts performed and suggests what to make next.
You can edit or remove any post on her calendar before it goes out.
Where does Otto fit?
Otto is the chief of staff. He answers questions about your hub, customers and sales, gives you a daily review of what changed and the next useful action, and can propose changes such as a discount code, a draft course, or an email or Auto DM draft. Nothing changes until you approve.
Otto also sits behind Insights: the Overview report suggests what to do next, and Ask Otto about this opens a chat with the report attached. Margo writes the marketing; Otto tells you where to point it.
How much do Margo and Otto cost?
All four agents spend one shared credit balance. Every creator gets 5 free credits a day, up to 30 a month; during a Hub trial you get 60 credits up front instead. When you want more, you buy credits separately, in monthly or yearly packs.
A post Margo publishes costs 2 credits, whatever the number of platforms it goes to, and an action Otto proposes costs 1 credit when you approve it. Chat and writing are charged by how much AI work they took, so a short question uses a fraction of a credit.
Which should you choose?
- You mostly need words: a free or paid chat assistant.
- You run a team with a brand voice to protect: Jasper or Copy.ai.
- You post to many networks and want one calendar: Buffer or Later.
- You sell on WithMe and want marketing that starts from your real products and customers: Margo and Otto, alongside a chat assistant if you like.
How do you start with Margo on WithMe?
- Start your 14-day trial and add at least one product to your hub.
- Open AI Agents in the menu (AI Team on your phone) and choose Margo.
- Tell her about your audience and what you want to promote this month.
- Connect Instagram, LinkedIn or Threads if you want her to publish for you.
- Review the plan, edit any post, and watch your credits in the receipt shown after each job.
What is not included?
Margo does not post to Facebook or TikTok, and she does not publish reels or stories for you. She does not run or buy ads. Handing Sal's leads to Margo for a follow-up email is not available yet. AI credits are bought separately; the free daily credits are enough to try the agents, not to run them all day. The AI team writes from what is on your hub and what you tell it, so check every claim, price and result before it goes out.
What does an AI marketing stack cost?
A lean stack is a free chat assistant and Buffer's free plan: $0 a month. A heavier one, with Claude Pro billed yearly ($17) and Later Starter billed yearly ($18.75), is about $36 a month before your platform; Jasper Pro alone is $59 a month billed annually (prices checked 11 November 2026).
WithMe is $25 per month billed annually (UK £25), with a 14-day trial and 0% WithMe commission. Stripe and PayPal fees still apply. One plan covers courses, coaching, community, memberships, digital products, email and Auto DMs. Optional AI credits, used by Margo and the rest of the AI team, are purchased separately.
AI marketing assistants: questions
What is the best AI marketing assistant for creators?
For writing alone, a general chat assistant such as ChatGPT or Claude is the best value. If you want posting and a calendar too, add a scheduler such as Buffer or Later. If you sell on WithMe, Margo plans, writes and publishes from what is already on your hub.
Can Margo post to Instagram for me?
Yes. Connect your Instagram account and Margo can publish scheduled posts to it, and to LinkedIn and Threads. Reels and stories are not posted for you; she reminds you to post those yourself.
How much does a Margo post cost?
A post Margo publishes costs 2 credits, however many platforms it goes to. Every creator gets 5 free credits a day, up to 30 a month, and more are optional and purchased separately.
Will Margo send emails without asking?
No. An email Margo drafts for your list goes out through WithMe's email only after you approve it.
Is Jasper worth it for a solo creator?
Usually not at first. Jasper Pro is $59 per seat a month billed annually (checked 11 November 2026) and is built for marketing teams. A solo creator who writes captions and emails gets most of the same value from a chat assistant.
