Sonaopus

Sonaopus is a context-layering tool that eliminates the need to re-explain your situation to AI every time you need something written. You enter the details of your situation once — case facts, an executive's preferences, a project's brief, a listing's context, a role's requirements and Sonaopus hands that information to whichever AI you already use (Claude, ChatGPT, or Gemini), so what comes back is specific to your actual work instead of generic. It's structured stage by stage, by profession, across five verticals: HR Managers, Executive Assistants, Project Managers, Real Estate Agents, and Recruiters. Each profession has its own sequence of stages covering the recurring documents and communications that role produces — for example, HR runs from Weekly Priority Planner through Job Adverts, HR Policies, Offer Letters and Contracts, Employee Relations Case Documents, Internal HR Communications, and HR Reports. Pricing: free to try (the first three stages, capped generations, no signup friction), then a one-time purchase for full access — no subscription. What it doesn't do: Sonaopus never sends, submits, or acts on anything automatically. Every output is a document or recommendation the user reviews, edits, and decides on themselves. It covers the writing and communication layer of these roles, not the entire job.

Sonar

Sonar drafts LinkedIn and X posts for founders from what actually happened in their working week. It connects read-only to the tools where the work already happens: Google Calendar, Google Meet, Zoom, Slack, Notion, Microsoft Teams, Granola, Fireflies and Wispr Flow. Each week it finds the moments worth saying, a decision made, something a client said, a number that moved, and drafts posts in the founder’s own voice, learned from their real published posts rather than from a style preset. LinkedIn and X each get their own register from the same identity. Every post is approved by the founder before anything publishes. Private individuals named in a meeting never reach a draft, and raw transcripts are discarded once the moments are extracted. One plan at $99 a month or $990 a year covers both platforms, every feature included, with a 7-day free trial. Agencies and ghostwriters run each founder in their own workspace.

Spintax

Spintax is a template language for producing many variants of a text from a single source. Beyond flat alternatives, it covers permutations that pick and order a subset, scoped variables, value-driven conditionals, locale-aware plurals and includes. The point is where variation comes from. Generating each text from a model costs money per output and drifts in quality across a large run — by page 400 the outputs converge on the same shapes. Spintax inverts that: have a model draft one richly varied template, review it once, then expand it locally, deterministically and for free. Every variation is one you defined, and an editor proofreads a single template instead of a thousand texts. The language is implemented by five independent open-source engines — JavaScript, PHP, Python, Object Pascal and .NET — all verified against one shared corpus of golden fixtures, so a template renders identically wherever it runs. Nothing calls a hosted service: rendering happens inside your own runtime.
