PostNext

PostNext brings social publishing, planning and AI-assisted content creation into one workspace for solo publishers and teams managing several brands. Its broad channel and format support is a strong fit for coordinating a publishing calendar; the main trade-offs are tight free-plan limits and sending AI prompts and text to OpenAI and Google Gemini.

Overview

PostNext can schedule or publish immediately to X, Instagram, LinkedIn, TikTok, YouTube, Threads and Bluesky. A visual calendar supports advance planning, moving posts when dates change and using best-time suggestions. It handles videos, photos, text updates, carousels and reels, giving publishers more flexibility than a text-only queue.

PostNext says it publishes through official platform APIs using OAuth 2.0 and does not store social account passwords. Its privacy policy says the service is hosted on Amazon Web Services, personal data sent over the internet is protected with SSL/TLS, and social account OAuth tokens are encrypted in Azure Key Vault. Optional MCP assistant access requires explicit OAuth authorization and can be revoked. The iOS and Android apps offer optional on-device biometric authentication.

Key features

AI tools generate captions, hashtags, ideas and images, and provide AI-powered fact-checking. Prompts and text go to OpenAI and Google Gemini for processing, a meaningful consideration for anyone working with sensitive material. Brand voice controls, templates and bulk generation give content work more structure, but AI use is limited by monthly credits on paid plans.

Teams get role-based access, draft review and shared content libraries. Separate brand profiles keep each brand’s voice, assets and channel logins apart, which is useful for agencies or publishers juggling distinct identities. Integrations include MCP AI assistants, WordPress and API keys. The Chrome extension can send a page, image or selected text to PostNext, draft with AI, schedule a post or save a draft.

The fair-use allowance is up to 1,000 scheduled posts per connected account. That is ample for many active calendars, but it is a ceiling to account for when managing high-volume publishing across multiple accounts.

Pricing

The free plan costs nothing and includes one connected account, one user, 10 scheduled posts per month, unlimited ideas, 10 MB of storage and limited customer support. It is a sensible way to try the calendar, but the post cap and single account make it a poor fit for sustained multi-channel publishing.

Premium costs $11 a month (billed €11 / month; annual plan saves €96). It raises the allowance to 15 connected accounts and unlimited scheduled posts, with one user, 10 GB of storage and 150 AI credits per month. This suits an individual managing several channels, provided one seat is enough.

Business costs $39 a month (billed €39 / month; annual plan saves €120). It includes 20 connected accounts, one user, unlimited scheduled posts, 50 GB of storage and 500 AI credits per month. The larger storage and credit allowances suit heavier solo use, but the single-user limit still rules it out for a team.

Teams costs $4 a month (billed €4 / user / month, from €20 / month; annual plan saves €36 / user), with a five-seat minimum. It includes unlimited users, five connected accounts per user, unlimited scheduled posts, 10 GB of storage per user and 50 AI credits per user each month. This is the plan built for shared work, though the minimum commitment starts at five seats. Enterprise has custom pricing for enterprise needs, volume discounts or custom integrations.

A free plan and 7-day trial offer two ways to evaluate the service before committing. Premium includes 24-hour email support; Business adds priority support within 24 hours; Teams includes live chat and email support within 12 hours.

Platforms

PostNext supports web, iOS, Android, an extension and an API. Its supported social channels are X (Twitter), Instagram, LinkedIn, TikTok, YouTube, Threads and Bluesky.

Who it's for

PostNext is strongest for social publishers who need one calendar for multiple formats and channels, and for teams that need review, permissions and brand separation. Premium fits a solo operator with several accounts; Teams is the more natural choice when colleagues need their own seats and shared workflows. It is less suitable for someone who only needs occasional captions or cannot send content to the named AI processors.

Pros and cons

Pros: Seven supported social channels and several post formats let users coordinate a varied publishing schedule in one place.

Pros: Team review, role-based access and separate brand profiles support collaborative work across distinct brands.

Pros: OAuth-based publishing and encrypted social tokens avoid storing social account passwords, according to PostNext.

Cons: The free plan permits only one account and 10 scheduled posts a month, so it is mainly an entry point rather than a full publishing setup.

Cons: AI text and prompts are processed by OpenAI and Google Gemini, which may not suit sensitive content.

Cons: Premium and Business are limited to one user; Teams requires at least five seats.

Alternatives

For a narrower focus on AI caption writing, compare the AI Social Media Caption Generators list. For turning existing material into new formats, see AI Content Repurposing Tools.

Optimate is worth considering if a smaller starter allowance suits: its free plan has three connected accounts, five scheduled posts at a time and five AI text generations, with Android, iOS and web apps. Ahrefs is a different choice for readers seeking site data and SEO tools, with limited Site Explorer and Site Audit access on its free plan. HIX.AI offers a free plan with 20 credits and supports web, Windows and macOS.

InMedia is a paid alternative with a free trial; its Starter plan costs $8.90 a month and includes 75 generations per month, one Brand Kit, templates, history and PNG/JPG export. Predis.ai may suit buyers looking for a paid content tool with 1,300 monthly credits and publishing to 10 channels on its Core plan, though that plan has no auto-posting.

Simplified offers a free plan with 1GB of storage and supports web, iOS and Android. TextCortex has a free plan with 50 MB of file storage. CaptionCraft is another freemium option for web-based caption generation.

Verdict

Choose PostNext if you want a multi-channel calendar, varied post formats and, on Teams, structured review and brand workflows in one service. Its strongest case is bringing planning and publishing together; look elsewhere if the AI data flow is unsuitable, you need a genuinely useful free publishing allowance, or your team cannot meet the five-seat minimum.
