Keryo vs PostMimic

Keryo is a web service that creates and schedules social media posts, rewriting one idea in a native style for each platform. It is aimed at freelance social media managers, ghostwriters, studios, and agencies handling client accounts. Supported networks are LinkedIn, X (Twitter), Instagram, Facebook, TikTok, YouTube, and Threads, and all seven are included on every plan. Users can set client brand guidelines once for generated posts. Scheduled content appears in calendar, list, or gallery views, and failed publishes can be retried with one click. Keryo tracks post performance by platform and keeps history over time. Its MCP server lets Claude, ChatGPT, and other compatible assistants create, schedule, publish, and check statistics. Plans are priced by client workspaces rather than connected channels. The Freelance plan costs €19.50 a month for three workspaces; Studio costs €44.50 a month for ten and adds advanced brand voice, post import, and per-platform analytics; Agency costs €99.50 a month for 30 and adds guided onboarding. A free plan and seven-day trial are available. The interface is bilingual in French and English.

PostMimic builds a model of a user’s writing voice from connected social accounts or uploaded posts and drafts, then uses it to prepare social content. Drafts can be reviewed, edited, or approved before publication, and content is rewritten for each supported network: X, LinkedIn, Facebook Pages, and Instagram. Brand rules can guide generations with topics, forbidden words, alliances, and other content guidelines. Paid subscriptions add cloud scheduling that can publish with the user’s computer off. The Free plan costs nothing and includes five cloud AI posts as a one-time allowance, one profile, all four platforms, basic analytics, and a read-only web portal. Starter costs $19 a month, billed monthly, with 200 cloud AI posts per month and one profile. Cloud AI uses DeepSeek by default; users can instead provide keys for DeepSeek, OpenAI, Anthropic, or xAI, or run local models through Ollama. Paid plans also list image generation, a content library, analytics, and manual DM replies; higher tiers add automation and Agent Mode. PostMimic is available on Android, iOS, macOS, web, and Windows.
