WriteFlow adds an AI writing assistant to every text box, from Gmail to LinkedIn, and a one-click prompt coach to ChatGPT, Claude and Gemini. It uses your own API key and has no WriteFlow server.
A thin, transparent layer between you and the AI provider you already use. You stay in control of every word that gets sent.
Click the W beside any text box.
A quiet helper beside the message box in AI chats.
The Review Workspace, on your device.
These are the extension running, not mockups. The AI-chat shots use a local test chat page.
Tailored support on these sites, plus any other site you turn on from the popup.
Social sites change their layouts often. When WriteFlow reads a post from nearby text, it shows you exactly what it read, and you can edit it before anything is sent.
WriteFlow has no server of its own, so there's nowhere for your writing to go except the AI provider you chose.
OpenAI, Anthropic, Google Gemini, Groq or OpenRouter. Your key stays in this browser.
Text goes from your browser to your provider, and only when you ask for a result.
WriteFlow never posts, sends or submits for you. You choose Use it, Insert or Copy.
No ads and no data sales. Usage counts stay on your device and never include what you write.
Read the full Privacy Policy.
You pay your AI provider directly for what you use. Pro unlocks the extras.
WriteFlow updates itself through the Chrome and Edge stores.
Comment boxes now open reply options for the post. When WriteFlow reads the post from nearby text, it shows "Replying to…" with an Edit link. New-post boxes get options that fit the site.
Everyone gets 100 finished Improves with no time limit and no card. Only finished rewrites count, and everything else stays free.
Rewrite any prompt in ChatGPT, Claude or Gemini using prompt-engineering best practice, streamed as it's written. Choose Best, Shorter, More detailed or Step by step, then Use it, Edit or Undo. Shortcut: Alt+Shift+I.
Pick the models you have, and WriteFlow suggests a cheaper or stronger one for each request. It never switches silently, and automatic routing is opt-in.
Save tasks from chats, compare two answers, link sources and evidence, and keep a decision trail. You can set preferences by category too.
Prompt checks, Optimize with requirement protection, context health, continue in a new chat, retry prevention, task splitting, and a local usage and cost summary.
No account, ever. To try it without a key, leave Settings → Provider on Mock: every feature returns sample results and nothing is sent anywhere. For real results, add your own key. Google Gemini's free tier in Google AI Studio is the easiest place to start.
OpenAI, Anthropic (Claude), Google Gemini, Groq and OpenRouter. You choose the provider and the models you want to use. Your key is stored only in this browser.
In ChatGPT, Claude or Gemini, type a prompt of six or more words and click ✨ Improve beside the message box, or press Alt+Shift+I. Your AI provider rewrites it into a clearer prompt, and you choose whether to use it. You get 100 free Improves with no time limit. Errors and cancelled ones don't count. After 100, Improve is part of Pro, and every other feature stays free.
When you ask for a result, the text you're working on, plus the post or email you're replying to for replies, goes directly from your browser to your AI provider, using your key. WriteFlow has no server and never sees it. Prompt checks run on your device. Details are in the Privacy Policy.
Never. Every result waits for you to choose Use it, Insert, Replace or Copy. Prompts in AI chats are never sent for you.
Pro is unlocked with a licence key from Gumroad, and the Gumroad page shows the current price and terms. The key is checked with Gumroad at most once a week. If the check fails because you're offline, you keep Pro.
Most often the selected provider doesn't match the key. For example, an OpenAI key won't work with Anthropic selected. Also check that the key hasn't expired or run out of credit. See Support for more.
WriteFlow is new, so there are no customer reviews here yet. If you try it, real feedback, good or bad, is wanted at helloanishupreti@gmail.com. This space will show real reviews once they exist.
