Strokes
Strokes is a desktop text editor for macOS and Windows with the AI inside the document. Select a passage, describe the change, and GPT, Claude, Gemini or Grok proposes it as a diff you accept or reject — nothing changes silently. You pick the model per request, and the assistant can work across the files in a project when you ask it to. Documents are files in folders on your computer: write, edit and export with no internet connection (AI features need a connection). Import from Word, Markdown and Notion exports; export to PDF, Word, EPUB, Markdown and HTML in one click; publish a document as a public read-only web page. Page view and pageless mode, standard blocks, version history kept on your device. Strokes does not train AI models on your content. Free plan with base models and no credit card; Pro at $25/month adds frontier models, voice mode and 15× the AI usage.

ToneBird
ToneBird is a socially fluent AI reply assistant that understands your relationships, what you have already said, and where you left off, then drafts the next reply in your voice inside the apps you already use. It works alongside readable reply fields in Gmail, Slack, WhatsApp, iMessage, Discord, WeChat, Lark, X, and other apps, so users do not need to leave the conversation, rebuild context, or copy responses back and forth. ToneBird uses earlier conversations, commitments, preferred forms of address, and relevant facts to create replies that fit both the person and the situation. It can also bring in information from connected documents or knowledge bases, such as agreed prices, project details, or other terms. Users can compare three drafts, tweak the wording, insert the preferred option into the reply box, review it, and send it themselves.

Sonaopus
Sonaopus gives your AI (Claude, ChatGPT, or Gemini) everything it needs to write the recurring work documents HR Managers, Executive Assistants, Project Managers, Real Estate Agents, and Recruiters need, over and over, from your situation, entered once.

From there, Sonaopus structures what your AI needs, stage by stage, so it writes job adverts, HR policies, status reports, listing descriptions, CVs screening, and more, in your voice, correctly the first time.
Free to try, no sign-up required. One-time purchase for the full version. No subscription.
Built for 5 professions: HR Management, Executive Assistant, Project Management, Real Estate, and Recruiting.
