Instead of a blank-slate chatbot, ContentIn starts by reading your LinkedIn profile and past posts to build a model of how you actually write — sentence length, vocabulary, and how you open a post. It then runs a short structured interview to fill a knowledge base with what you are building, who you serve, and the stories only you have. The daily loop is intentionally simple. You drop in what happened during the week — wins, client conversations, half-formed thoughts — and ContentIn turns that raw material into a batch of scheduled posts. Each edit you make and each post that goes live feeds back into the voice model, so the drafts supposedly get closer to your own writing over time rather than drifting away, which is what happens with generic AI tools that start from zero every session. Beyond the writing itself, the platform bundles the rest of the publishing loop: an idea manager and generator, AI images and quote cards, carousels and other LinkedIn formats, a scheduler for both personal and company pages, post analytics, scheduled follow-up comments, and AI-generated comments based on your ICP. There is also a Telegram bot and an MCP server so you can work from your phone or from an MCP client such as Claude or Cursor. Pricing sits far below hiring a human ghostwriter, with a seven-day free trial and monthly tiers in the $39–$48 range depending on whether you need company pages and business features. **Pricing & Plans:** Seven-day free trial. Growth is $39/month; Pro is $48/month and adds company pages, more planned posts, 100 AI images a month, custom AI instructions, the MCP server, and Telegram bot. - **Voice-trained ghostwriter:** Reads your profile and past posts to model tone and structure, then writes drafts most users edit by less than 10%. - **Weekly batch planning:** Drop in the week's raw material and get a set of drafted posts distributed across your content pillars. - **Scheduler and follow-up comments:** Queue weeks ahead for your profile and company page, and automatically add the link or lead magnet after a post lands. - **Visual formats built in:** Attach AI images, quote cards, GIFs, video, and carousels to drafts without leaving the editor. - **Analytics and AI comments:** See which angles performed, and generate meaningful replies based on your ideal customer profile and pillars. **Strengths:** Voice model trains on your own posts rather than generic prompts; Full publishing loop in one tab, from idea to analytics; Substantially cheaper than a human ghostwriter **Limitations:** Focuses on LinkedIn only, unlike broader social suites; Quality still depends on how much you feed the knowledge base [Profile (Markdown)](https://openaitools.app/tool/contentin.md) ## Spiral Most AI writing tools produce text that reads generically because they have no model of who is writing. Spiral approaches the problem with stylometry, the long-standing statistical practice of identifying authorship from patterns in language — sentence length distribution, punctuation frequency, word choice ratios, and syntactic habits. You supply samples of your own writing, past brand documents, or connected social accounts, and Spiral measures those patterns into a reusable style. The output is channel-aware. Spiral adapts the same voice to different formats, producing hook-first short posts, subject-first long-form pieces, or narrative LinkedIn posts, and it highlights the AI tells it strips out — filler openers, overused hype verbs, and em-dash clutter. Styles can be shared with a team so brand voice stays consistent no matter who is drafting. Spiral is built for live collaboration with AI agents as well as human writers. You can run multiple drafts at once, get feedback as you go, and copy prompts straight into an agent workflow, keeping voice consistent whether you are writing a short social post or a several-thousand-word essay. It is distributed through the Every bundle rather than as a standalone subscription. **Pricing & Plans:** Access to Spiral is included in the Every bundle at $30 per month, which combines Spiral with the publisher's AI analysis, courses, and other software. There is a free way to start writing on the site, with the dashboard available to bundle subscribers. - **Stylometry-based style engine:** Measures your sentence length, diction, punctuation habits, and openers from your published work, then applies that measured signature to new drafts across channels. - **Voice from your own sources:** Build a style from writing samples, uploaded brand and verbal-identity documents, or by connecting your social channels, with prompts when more input is needed. - **Channel-specific drafting:** Produces hook-first short posts, subject-first long-form pieces, and narrative formats, with AI tells like filler openers and hype verbs flagged and removed. - **Team-shareable brand styles:** Custom styles can be reused by an entire team so on-brand copy is available from day one without prompt engineering. - **Agent and live-writing workflows:** Run several drafts at once with real-time editorial feedback, and copy prompts directly into your own AI agent. **Strengths:** Combines measurable style analysis with practical drafting, not just tone sliders; Handles multiple formats, from short social posts to long essays; Team-shareable styles keep brand voice consistent at scale; Works alongside external AI agents via copyable prompts **Limitations:** Full access is tied to the wider Every bundle rather than sold separately; Style quality depends on having enough of your own writing to analyze; Aimed mainly at writers and marketers, not general-purpose chat [Profile (Markdown)](https://openaitools.app/tool/spiral.md) ## Frequently Asked Questions ### How do ContentIn and Spiral compare in monthly traffic?
