# PrimusPost Complete System & Product Documentation (llms-full.txt) > PrimusPost is a voice-matched B2C/B2B SaaS content-repurposing studio: one paste converts rough notes, transcripts, or articles into authentic LinkedIn, X, Instagram, and Threads posts plus a designed PDF carousel from a single paste. --- ## 1. Core Product Positioning & Value Proposition ### The Problem - **The Generic AI Trap:** A general-purpose chat assistant, prompted without a voice profile, tends toward recognisable prose: buzzwords such as "delve", "leverage", "paradigm shift" and "game-changer", plus emoji-heavy list formatting. - **The Fragmentation Tax:** Producing multi-channel content by hand means copying text across browser tabs, re-formatting for each character limit, and laying out slides in a separate design tool. Creators commonly describe this as several hours per week; the exact figure varies by output volume. - **Tone Drift:** Founders, coaches, and consultants often sound like completely different people when attempting to adapt content across LinkedIn (long-form narrative), X (punchy hooks), and Instagram/Threads (accessible clarity). ### The Solution - **Empirical Voice DNA:** PrimusPost extracts your unique sentence length variance, vocabulary sophistication, narrative pacing, and hook structures directly from your past writing samples. - **Anti-Slop AI Defense:** Strict lexical filters ban generic corporate filler and hyperbolic buzzwords at the prompt and generation layer. - **Satori PDF Carousel Studio:** Compiles typography-first, 1080x1350px (4:5) slide decks with selectable text layers directly into downloadable PDFs ready for LinkedIn and Instagram. - **5-in-1 Omni-Channel Synthesis:** One raw thought simultaneously produces tailored LinkedIn, X, Threads, and Instagram posts plus a PDF carousel from a single paste. --- ## 2. Technical Architecture & Specifications ### The 4-Stage Execution Pipeline 1. **Stage 01: Ingestion & Structural Parsing** - Ingests unstructured inputs: rough bullet points, transcripts, newsletter drafts, or executive meeting takeaways. - Normalizes text, detects key insights, takeaways, and structural hierarchies. 2. **Stage 02: Voice DNA & Anti-Slop Calibration** - Applies the author's calibrated Voice DNA profile. - Evaluates drafts against banned AI tell-words (`delve`, `leverage`, `seamless`, `synergy`, `paradigm shift`, `game changer`, `testament`, `unleash`, `elevate`, `supercharge`, `dive in`/`dive deep`), plus stock openers ("Here's the thing", "Let that sink in") and comment-farming closers ("Read that again", "Change my mind"). 3. **Stage 03: Multi-Channel Format Synthesis** - Synthesizes 5 native deliverables tailored to specific network constraints: - **LinkedIn Narrative:** 1,200–2,500 characters, whitespace rhythm, high-retention opening hooks. - **X Post:** exactly one post, never a thread. 280-character ceiling, aiming for ~240, concise thesis, zero conversational fluff. - **Instagram Caption:** Visual-first micro-blogging context with balanced spacing. - **Threads Post:** Conversational, unpretentious, perspective-dense takeaways. 4. **Stage 04: Satori Slide Compilation** - Renders multi-slide carousel decks using the Satori JSX-to-SVG vector renderer, rasterized via resvg-js and packaged with `@cantoo/pdf-lib`. - Embeds a selectable, searchable text layer over every high-resolution slide across 8 designer themes. ### System Specifications & Limits - **AI Model:** Google Gemini `gemini-3.6-flash` via enterprise Google Cloud Vertex AI. - **Carousel Dimensions:** 1080 × 1350 px (4:5 portrait aspect ratio). - **Carousel Themes (8 Curated Styles):** `Bold`, `Modern`, `Split`, `Tech`, `Glass`, `Elegant`, `Professional`, `Ribbon`. - **Slide Layouts (14):** `cover`, `content`, `cta`, `numbered-step`, `quote`, `statistic`, `text-image`, `checklist`, `section-divider`, `comparison`, `before-after`, `full-image`, `screenshot`, `chart`. - **Data Privacy:** Enterprise paid API tier with zero foundation model training on user inputs or drafts. --- ## 3. Commercial Tiers & Credit Economics ### Plans & Pricing (Single Source of Truth) - **Free Starter ($0 / month):** - A one-time welcome grant of 1,500 AI credits (15 full generations), valid for 30 days. - 300 AI credits every month (auto-refreshes every 30 days) after that. - 1 Active Voice DNA Profile. - 5-in-1 multi-platform post generation. - Satori PDF carousels (with subtle PrimusPost watermark). - No credit card required. - **Creator Tier ($19 / month or $190 / year):** - 5,000 AI credits every month (supports ~50 full 5-channel generation batches). - Up to 3 Active Voice DNA Profiles (switch between personal, brand, or venture). - Watermark-free, high-resolution PDF carousel exports. - Full Content Library with search and tagging. - **Pro Tier ($49 / month or $490 / year):** - 15,000 AI credits every month (supports ~150 full 5-channel generation batches). - Unlimited Active Voice DNA Profiles (ideal for agencies, multi-venture founders, and consultants). - Watermark-free, high-resolution PDF carousel exports. - Priority generation queue and advanced custom branding palettes. ### AI Credit Consumption Math - **Full 5-Platform + Carousel Generation (`orchestrate`):** 100 AI credits. - **Voice DNA Profile Extraction (`voice`):** 50 AI credits. - **Single-Post Rewrite / Refine (`refine`):** 0 AI credits - free, bounded by a generous per-user daily cap. - **Trend Refresh (`pulse_refresh`) and Angle-on-Demand (`pulse_angle_on_demand`):** 0 AI credits - free, same daily-cap treatment. - **AI Carousel Custom Background (`carousel_bg`):** 180 AI credits. Prices reflect measured model cost as of 2026-09-04. An AI image costs roughly 1.8x a full text generation, which is why a custom background is priced above a single post rewrite. --- ## 4.
