Use Case Recommendations
Best for: Kerlig
Kerlig is a macOS writing assistant that works inside whatever application you are already in rather than asking you to paste text into a separate window. A global hotkey (option-space by default) opens it over any app, so proofreading a Slack reply, rewriting an email, tightening a Jira ticket or converting a blob of JSON into a TypeScript interface all happen without a context switch. It ships built-in actions — proofread, improve, summarise, shorten, simplify — and lets you write your own, including specialised personas, so recurring tasks become one keystroke. A tone-of-voice setting keeps rewrites sounding like you instead of like a model. It reads attachments, so you can chat with documents, web pages, ebooks and images, and a deep-research mode drives reasoning models through multi-step research against online sources with citations you can open. Models are entirely bring-your-own-key across more than 350 options from OpenAI, Anthropic, Google, Groq, Perplexity and OpenRouter, plus local execution through Apple Foundation Models, Ollama and LM Studio, which means messages go directly from your Mac to the provider and history stays encrypted locally. There is a headless mode for background actions and CLI-based deployment for teams. The licence is a one-time purchase, so the only recurring cost is your own token spend.
Ideal use cases:
- •Teams or individuals who need global hotkey invocation over any macos app
- •Teams or individuals who need built-in and fully custom actions
- •Teams or individuals who need tone-of-voice personalisation
- •Teams or individuals who need chat with documents, web pages, ebooks and images
- •Anyone focused on macos workflows
- •Anyone focused on byok workflows
Best for: TypeBoost
TypeBoost is a macOS and iOS writing tool built around a single ergonomic decision: your saved AI prompts apply to selected text in whatever application you are already in, triggered by one keyboard shortcut, with no copy-paste and no switching to a chat window. That removes the friction that stops most people using AI writing help for short everyday text — the effort of moving the text somewhere else and bringing the result back exceeds the value of the edit. The prompts are yours and fully customisable, so the tool becomes a personal writing toolkit rather than a fixed set of vendor-chosen actions like 'make professional'. A prompt library is published for people who do not want to write their own from scratch. Voice input is supported alongside text selection, so you can dictate as well as transform. There is an interactive demo on the site showing the basic flow before you install anything, and an iOS app alongside the Mac download. The audience it names is freelancers, founders and indie hackers. Pricing is unusually modest: the free plan includes a fast default model at no cost, and the paid plan at $5/month adds multiple model choices.
Ideal use cases:
- •Teams or individuals who need apply saved ai prompts to selected text inside any macos app
- •Teams or individuals who need single keyboard shortcut — no copy-paste, no app switching
- •Teams or individuals who need fully customisable prompts rather than fixed vendor actions
- •Teams or individuals who need published prompt library as a starting point
- •Anyone focused on macos workflows
- •Anyone focused on ios workflows
