The most powerful free LinkedIn content tool: write, format, preview, audit, schedule, and publish better LinkedIn posts - no signup required.
linkedinpreview.com · Blog · Changelog
LinkedIn's native editor gives you no preview, no drafts, no formatting, and no feedback. LinkedIn Preview fixes all of that - and has grown from a formatting tool into a full, open-source LinkedIn content platform. The core editor stays free and login-free forever: accounts are anonymous by default, and you can bind an email or connect LinkedIn whenever you want cross-device sync, scheduling, and one-click publishing.
- Rich text editor with Unicode bold, italic, underline, strikethrough, bullet and numbered lists
- Pixel-accurate live preview on mobile, tablet, and desktop widths - including the "see more" truncation exactly where LinkedIn cuts it
- Realistic feed preview: see your post surrounded by feed posts, like it will actually appear
- Image and video upload, copy-to-clipboard in LinkedIn-ready format, shareable draft URLs
- Embeddable widget variant for third-party sites
- Generate posts from a topic, your notes, your voice (audio), a file, or any URL
- AI chat assistant, quick actions (shorten, lengthen, variations), hook generation, and inline suggestions
- AI post analysis with quality scores, plus client-side scoring: readability, sentence flow, length status, character/word/line/hashtag/emoji counts
- Branding-aware generation: your positioning, expertise, writing style, dos and don'ts, and knowledge base are injected into every prompt
- Connect your profile (OAuth, URL, or just your name) and get a real audit of your recent posts: content mix, hooks, CTAs, engagement by category, topics you cover, and the gaps that matter for your goal
- Every number is measured server-side from scraped data - the AI only labels, it never invents metrics
- The audit feeds a personalized content plan with pillar post ideas generated in your voice
- Multi-draft management with statuses, format labels, filtering, and 2-second auto-save (Supabase-backed)
- Post scheduling, content calendar, best-time-to-post, and one-click publishing via LinkedIn OAuth
- Carousel creator: drag-and-drop slide editor with 14 templates, 11 themes, AI generation, and watermark-free PDF/PNG export
- Content strategy wizard with weekly AI post ideas
- LinkedIn analytics import and performance insights
