As answered by people managing CodeSandbox and TextWisely.
TextWisely's answer:
TextWisely is built specifically for macOS users who write a lot and donβt want to break their flow. Unlike browser-based tools or clunky extensions, TextWisely works natively across any Mac app β from Slack and Notes to Mail and Safari β without requiring you to copy-paste into ChatGPT or switch contexts.
Itβs fast, always available via a shortcut, and designed with real-world writing tasks in mind β like replying to emails with full context, fixing grammar instantly, or changing your tone before sending a message. It doesnβt just polish your text β it removes the friction around writing.
In short: TextWisely brings GPT-quality writing help into your daily Mac workflow without getting in your way.
TextWisely's answer:
TextWisely was born from a personal itch π§©
β οΈ Sending numerous Emails and Slack messages daily, I found myself constantly switching apps and re-entering the same prompts into ChatGPT to refine my writing.
π‘ This inspired me to create TextWisely to boost writing speed, reduce context switching, and improve quality with instant text actions: βοΈ Grammar corrections, βοΈ Email drafts, βοΈ Structured writing, βοΈ Tone changes, βοΈ Translations ...and more
π It's a native macOS desktop app β shortcut-heavy for power users, but also click-friendly for those just starting out.
π Give it a try: https://textwisely.ai
TextWisely's answer:
Most writing tools force you to copy, paste, and jump between apps β or lock you into a browser extension that only works in certain places. TextWisely is different.
Itβs a native macOS app that works everywhere you write β Slack, Mail, Notes, Google Docs, you name it. Just hit a shortcut, and you can instantly rewrite, correct, or respond to text without breaking your flow.
You get: π No context switching β stay in the zone, β‘ Super fast β opens instantly, runs smoothly, π© Email context support β attach threads, get smart replies, π Built for privacy β nothing is stored on our servers, βοΈ Natural tone control β adjust writing style on the fly
If you care about speed, fluidity, and staying focused while writing β TextWisely is built for you.
