15 best content writing tools for agencies and marketers in 2025

Dedicated content writing tools speed up content strategizing, research, and the creation process itself — all without compromising on quality. Plus, they help content collaboration tools move faster with approvals, in-document comments, and a bunch of other handy features already baked in.
To cut you some slack, I’ve compiled a list of some of the best content writing tools available, spanning across various categories from platforms that help with the writing process to SEO software, editing tools, and more.
1. Planable – best for collaboration, approvals, and social media scheduling
Planable is a collaboration platform that makes it easy to work on anything and everything content-related — social media posts, blogs, newsletters, scripts, just to name a few.
Planable content writing tool interface
The platform includes numerous collaboration tools like in-document comments (internal and external), clear text suggestions, and annotations — just like Google Docs, but better.
Planable stands out through its customizable approval workflows. You can streamline review and approval through four different workflow types: none, optional, required, and multi-level — the latter being the highlight here. You can set up multiple approval layers, and content has to go through each specific level to get published.
Planable’s review and approval workflow interface
The platform also takes care of content planning — you can set up your blog content calendar via a drag-and-drop interface. Plus, Planable also doubles as a social media management tool.
That means you can schedule social media posts across most popular social platforms, while its color-coded labels are perfect for planning, organizing, and tracking multi-channel marketing campaigns.
Planable’s content calendar interface
Other handy features include the AI Creation Hub — great for content ideation or editing — and the option to invite external stakeholders to your workspace by simply sharing an email link.
Key features:
- Real-time collaboration: Work with team members in real time through comments, suggestions, and annotations. Keep work-in-progress content away from your client’s view through internal comments and posts.
- Media asset library: Store content assets (images, videos, GIFs) directly within the platform. Collaborate and work on visuals through comments and Planable’s built-in visual editing tools.
- Content editor: Write content from scratch with the platform’s native content editor. Embed YouTube videos or Tweets, add bullet lists, checklists, and more.
- Social media scheduling tools: Schedule content across one or multiple networks simultaneously. Use Planable’s Content Recycling feature to automatically re-post evergreen content.
- Workspaces and views: Keep work organized through client or brand-specific workspaces. Plan content via list, calendar, grid (Instagram-specific), or feed views. Leave comments and approve posts directly from the content preview.
Drawbacks: Planable currently lacks integrations with CMS platforms — you cannot publish posts from Planable to your CMS.
Pricing: Planable starts at $33 per month per workspace (billed yearly). You can also plan your first 50 posts completely for free.
2. Google Docs – best free tool for long-form content writing
Google Docs is simple, free, and effective. Writers and editors can collaborate on long-form content through comments, annotations, and suggestions.
Plus, you can use Google Gemini to write up quick first drafts, rewrite existing or AI-generated content, and create images. Google Docs also includes paid versions with a few extra features like simple approval workflows, for example.
Key features:
- File-sharing and collaboration: Share files via links with custom permissions (editor, commenter, viewer). Collaborate with multiple team members in real time, leave feedback via comments and suggestions, and see whether it was implemented correctly through version control.
- Extensions: Use Chrome’s add-on library to add extra features — SEO tools, form builders, and integrations with graphic design platforms are just a few examples.
- Templates: Speed up the content creation process through numerous use case-specific templates — from reports and newsletters to sales quotes, brochures, and more.
Drawbacks: Google Docs doesn’t go beyond basic functionalities — it lacks more advanced features like multi-level approvals, direct publishing, and so on.
Pricing: Paid versions start at $6 per user per month (billed yearly).
3. ButterDocs – best for collaborative writing and editing
ButterDocs helps writers and editors work better together. The platform lets editors set up content briefs and assign them to particular writers — complete with extra notes and references for research.
Once a draft is ready, writers and editors can make tweaks in real time via comments, track changes through version control, and so on. Branch copies are also super handy — you can edit content separately without altering the original draft.
Key features:
- Blocks: Create content outlines through a Kanban-style interface — each column corresponds to a specific blog post section, while each card represents a particular sub-section. Leave descriptions under each card and add extra research links or instructions through notes for easy writer access.
- Writer productivity tools: Use Focus Mode and Dark Mode to eliminate distractions or push yourself out of writer’s block through timed word sprints. Save scrapped paragraphs in the platform’s Stash.
- Status tracking: Easily see work-in-progress or completed posts through a unified dashboard with pre-defined labels. Let writers mark their content for feedback and tag their editors.
Drawbacks: ButterDocs is still in early access — it’s not a complete product yet.
