Our verdict on Prose
Prose is a Chrome extension for professionals, non-native speakers, and anyone who wants on-demand writing assistance without rewriting their voice. It corrects grammar, spelling, punctuation, clarity, flow, and awkward phrasing in selected text. The workflow is direct: select text in a Chrome text field, right-click, and choose “Fix my text.” Corrected text can also be produced through a clipboard-based workflow, giving users a lightweight way to refine writing where they already work.
The pricing model has two clear paths. The free plan, “Free — your own API key,” includes unlimited fixes and supports OpenAI, Claude, or Gemini. There is no Prose subscription, but usage is billed by the selected AI provider. The paid option is “Buy credits,” a one-time $10 purchase that requires no API key. Credits never expire, and users can top up anytime and use Prose when needed. This structure suits people who already have an AI provider account or prefer prepaid access over subscription billing.
Prose fits writing workflows built around Chrome, with integrations or supported use across Gmail, Slack, Notion, LinkedIn, Google Docs, Linear, and X. Its focused correction feature set and right-click workflow make it a practical choice for users who want targeted edits rather than a broader writing suite. Chrome users comfortable with an API key should find the free plan especially relevant. People who need a desktop app, broader platform coverage, or an all-in-one checker should choose an alternative.
