The marketing stops the week the building starts
There's always a bug worth more than a post. SlideBuddy writes carousels about the problem your product solves, designs them in your look, and publishes them — including through the months you disappear into a rewrite.
- Drive it from Claude or Cursor
- Teach the problem, not the feature list
- Keeps going while you're heads-down
Five carousels free, no card · Or 7 days of everything, publishing included
Whether this fits depends on one thing
Worth settling before anything else on this page, because the answer is genuinely different at each end.
Consumer apps and indie products
Fitness, finance, productivity, hobby tools — anything with users rather than procurement. Your people are on Instagram and TikTok, which is exactly where this publishes. Good fit.
B2B SaaS
Your buyers are on LinkedIn and X. We don't reach X at all, and LinkedIn only on the $199/mo Agency plan. On anything below that you'd be publishing where your customers aren't. Probably the wrong tool.
If you're somewhere in between — a developer tool with a real Instagram following, say — the honest test is whether you'd post there anyway if it took no effort. If not, automating it won't create the audience.
Why founder accounts go quiet
Marketing is the thing that slips
There's always a bug worth fixing more than there's a post worth writing. So the build ships and nobody hears about it.
Launch spikes and then silence
One good Product Hunt day, a week of momentum, then three months of nothing while you go back to building. The audience you bought doesn't compound.
You're too close to explain it
You've thought about the problem for a year, so the obvious framing feels boring to you and reads as revelatory to everyone else. Most founders undersell the thing that would land.
What to post
The problem is the content, not the product
People searching for what your app does aren't searching for your app. They're searching for the thing that's annoying them.
Teach the problem, not the product
The people who need your app are searching for the problem, not the category. Posts about the problem reach them; posts about your feature set reach people who already know you.
Show what it replaces
The manual process, the spreadsheet, the four-step workaround. Comparison against the status quo lands harder than comparison against a competitor.
Build in public, without the theatre
Decisions and trade-offs, not revenue screenshots. What you chose and why is genuinely interesting; MRR charts are content about you.
Turn the changelog into something readable
Each meaningful release is a carousel about the problem it solves. It gives you a steady supply of posts you were already going to write badly in a changelog nobody reads.
More on the practical side of this in marketing an app when you're the only one building it.
What it handles
Everything between the idea and the post
You keep the point of view and the last word. It does the production, on a schedule.
Drive it from your editor
Studio and Agency include an MCP server, so you can queue a carousel, check what's posted and pull performance from Claude or Cursor without opening a dashboard.
One theme becomes a month
Give it the problem you solve and it produces a run of carousels around it, each taking a different angle rather than restating the same post.
Your product's look, not a template
Palette, fonts and logo set once, applied to everything after. Rotate a few of the 20 styles so a feed built at volume doesn't read as one layout repeated.
Posts while you build
Generated overnight, approved on one screen, published across the day. The point is that the marketing keeps going during the weeks you're heads-down.
Studio and Agency
Run it from your editor
An MCP server, so the tool you already have open can drive this one. No dashboard, no context switch.
Connected in Claude or Cursor, you can ask for:
list_brandsYour brands and their settingsqueue_slideshowGenerate a carousel on a given topiclist_slideshowsWhat's been made and what's scheduledget_performanceHow posts actually didget_content_learningWhat the bandits have worked out about your audienceget_account_statusWhether every connection is still alive
Which means "queue three carousels about onboarding friction" is a sentence you type where you already are. It also means your own scripts can drive it — a release hook that queues a carousel about what shipped is a few lines.
Before you start
When this is the wrong tool
Four things worth knowing now rather than three days into a trial.
If you're B2B, this probably isn't it
B2B software mostly lives on LinkedIn and X. We don't reach X at all, and LinkedIn only on the Agency plan. If your buyers are on those two platforms, a tool that publishes to Instagram, TikTok and Facebook is solving a distribution problem you don't have.
It doesn't make video
No demo clips, no screen recordings, no Reels. For a product that's easiest to understand by watching it work, that's a genuine gap — carousels explain a problem well and demonstrate an interface poorly.
It doesn't know your product
It writes from what you tell it. Specifics — how your thing actually works, what makes it different — come from you, and generic product copy converts worse than nothing.
One brand on the entry plan
Solo covers 1 and 3 connected accounts, and no MCP. Running several products, or wanting the MCP server, is a Studio job rather than a $29 one.
Questions
- I'm building B2B SaaS. Is this useful?
- Probably not, and it's better to say so. B2B software mostly reaches its buyers on LinkedIn and X. SlideBuddy doesn't support X at all, and LinkedIn only on the $199/mo Agency plan — so on Solo or Studio you'd be publishing to Instagram, TikTok and Facebook, which is likely not where your customers are. If you're consumer-facing, or you have a genuine Instagram and TikTok audience, that changes the answer completely.
- What does the MCP server actually do?
- It exposes your account to an AI coding assistant: list your brands, list and queue carousels, check account connection status, and pull performance and content-learning data. So you can say "queue three carousels about onboarding friction" in Claude or Cursor and never open the web app. It's included on Studio and Agency.
- Can it post about my changelog automatically?
- Not wired to your repo or release notes, no. What it does is turn a topic you give it into a carousel, which makes a release a two-minute job rather than an afternoon. If you want that scripted, the MCP server means your own tooling can queue it.
- Does it make demo videos or screen recordings?
- No. Carousels and TikTok photo mode only. For a product that's best understood by watching it work, that's a real limitation — this is better at explaining the problem you solve than at demonstrating your interface.
- I'm a solo founder. Is the automation worth it over just posting manually?
- Only if consistency is your actual failure mode. If you post reliably by hand, this saves you design time and not much else. The case for it is the month you disappear into a rewrite and the account goes quiet — that's the gap it's built to cover, and it's the one most solo founders recognise.
- Can I try it without a card?
- Yes. The free plan gives you 5 carousels on one brand, every style, full resolution, no watermark and no card. It downloads rather than posts, so the automation and the MCP server need the 7-day trial — that takes a card and cancels any time before it ends.
Keep shipping. Let the posting carry on without you.
Set your product and your look once, approve the first batch, and stop losing the months you spend heads-down.
Full features for 7 days, cancel any time before it ends. Card required to start the trial so posting can begin immediately — or take five carousels free on the no-card plan, for ever.
