Textglow

TextGlow is a Chrome extension that rewrites drafts in place in Gmail, Slack, LinkedIn and other sites. Pick one of ten tones, click the sparkle icon, and the text is replaced. A free tier needs no account, and Pro adds higher limits.

TextGlow is a browser extension that rewrites what you type directly inside the text field where you are typing. Instead of copying a draft into a chatbot, waiting for a response and pasting it back, the writer clicks a sparkle icon that appears beside the field, picks a tone, and the draft is replaced with a polished version. The pitch is speed and the absence of prompt writing: there is nothing to configure beyond choosing how the message should sound. The tool offers ten tones, including professional, friendly, confident, concise, empathetic, persuasive, direct, polite, funny and flirty. It is aimed at people who write many short messages a day: account executives answering client email, remote teams balancing warmth and directness in Slack, LinkedIn creators who want posts that read like a person rather than a template, and non-native English speakers who want phrasing that sounds natural instead of merely correct. The homepage lists support for more than 50 languages, and dedicated pages cover Gmail, LinkedIn, Slack and translation use cases. In practice, the free plan needs no account. Installing the extension from the Chrome Web Store is enough to start, with a daily allowance of rewrites and a cap on draft length. The paid Pro plan raises both limits, promises faster responses and adds a One-Click mode that skips the tone modal and swaps the text immediately. The site also hosts a browser playground where a rough draft can be tested before installing anything. The developer states that text is processed without being stored. Among alternatives, TextGlow sits closer to lightweight rewriting add-ons than to full writing suites. Grammar checkers focus on correctness, and general chatbots offer more flexibility but require a context switch. TextGlow trades breadth for a narrow, fast workflow aimed at tone adjustment in everyday messages. Buyers who need long-form drafting, document editing or support outside the browser will find it limited, while those who mainly want quicker, better-sounding replies will find the scope matches the job.
