Planable is a social media management platform built for agencies and marketing teams that plan, review, approve, and publish content across multiple clients and channels.

In Planable, every client gets its own workspace with a visual preview of how posts will look before they go live. Team feedback, internal notes, and client approvals happen in one place. Clients can approve without creating an account.

Approval workflows Optional โ€” approval available but not required Required โ€” at least one approver must sign off before publishing Multi-level โ€” sequential stages (team โ†’ legal โ†’ client)

Posts can auto-schedule on approval. Lock content after sign-off so nothing changes last minute.

Supported channels: Facebook, Instagram, LinkedIn, X, TikTok, YouTube, Pinterest, Google Business Profile, and Threads.

Planning tools: Feed, Calendar, Grid (Instagram), and List views. Campaigns group posts by launch or theme. A shared Media Library keeps brand assets reusable across workspaces.

Analytics and listening: Per-page and cross-channel Analytics with customizable reports, Competitor Analytics, Social Listening across X, Reddit, YouTube, and TikTok, and a Social Inbox for replying to comments and DMs without switching tabs.

AI tools: AI caption generation, AI-generated ALT text, and Brand Context. Set a client's tone of voice once, and Planable's AI uses it every time content is generated for that workspace.

Planable also offers a Public API and an MCP integration, so teams can connect AI assistants like Claude, ChatGPT or build custom automations on top of their content workflows.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

Questions & Answers

As answered by people managing Planable.io and KnowCSS.

Who are some of the biggest customers of your product?

Planable.io's answer

KFC, Ecco, Mastercard, Soedexo, Peroni, Bolt, SMEG, Warner Music Group

How would you describe the primary audience of your product?

Planable.io's answer

Marketing agencies and in-house social media teams managing content across multiple clients, brands, or locations. Typically 5 to 60 people, running 5 or more client workspaces across 10+ social channels. Common industries include digital marketing agencies, real estate, hospitality, retail chains, financial services, and B2B/SaaS brands.

What makes your product unique?

Planable.io's answer

Planable is built around collaboration first, publishing second. Every post lives in a visual workspace where teams, clients, and stakeholders see a realistic preview of how content will look on each platform; before anything goes live. Clients can approve posts directly without creating an account. Approval workflows are a first-class feature: optional, required, or multi-level. Internal comments stay hidden from clients. Content locks after approval. Posts auto-schedule on sign-off. Each client gets a separate workspace with its own pages, roles, and settings, so agencies can manage 10+ clients without mixing work.

Why should a person choose your product over its competitors?

Planable.io's answer

Most social media tools are built for publishing. Planable is built for the review cycle that happens before publishing. The structured approval flow (combined with per-client workspaces, granular roles, internal vs. client visibility, and real platform previews) makes it the tool agencies reach for when spreadsheets and email chains stop working. It also covers the full content pipeline: planning, collaboration, scheduling, analytics, competitor tracking, social listening, and community management, all in one place.

What's the story behind your product?

Planable.io's answer

Planable was founded in 2016 by Xenia Muntean, Nicolae Gudumac and Vlad Calus. Xenia was running a social media agency and spent more time managing content feedback over email than actually creating content. They built Planable to fix that: a single visual space where content gets created, reviewed, and approved without the chaos. The company joined Y Combinator in 2018 and has since grown to serve thousands of agencies and brands worldwide.

    Useful App

    In general, Planable is great and I feel that it saves me a ton of time. It's very simple to use, and as I have a staff to work with as my agency grows, I'll appreciate it even more.

    My favorite aspect of Planable is how simple it is for my clients to approve posts, even though it's simple to set up and use. I must also add that I like how smoothly the phone app functions.
