WriteFlow AI door Anish upreti

WriteFlow AI helps you write better in any text box, and get better answers from AI chat assistants. It uses your own API key from OpenAI, Anthropic, Google Gemini, Groq or OpenRouter, so your text goes straight from your browser to the provider you choose. There is no WriteFlow account and no WriteFlow server in between.

NEW IN 0.50.0: COMPARE AIS
Ask the same question to two to four AI models at once and read the answers side by side. WriteFlow then points out where the answers agree, where they give different facts or figures, and which claims have no evidence. It never picks a winner for you. You can save the question and all answers to your Review Workspace.

ONE-CLICK PROMPT IMPROVE
In ChatGPT, Claude or Gemini, click Improve beside the message box (or press Alt+Shift+I). Your AI rewrites your draft into a clearer prompt with the task, context, format and limits, and marks details you may have left out. Choose Best, Shorter, More detailed or Step by step, then use it, edit it or undo it. The first 100 Improves are free, with no time limit and no card needed.

WRITE AND REPLY WHERE YOU TYPE
• Rewrite, shorten, fix grammar, change the tone or translate your text.
• Write It For Me: describe what you want to say and get a draft that fits the site.
• Replies that read the post, comment or email thread you are answering, so the draft fits the conversation. When WriteFlow reads a post from the page, it shows you what it read and lets you edit it first.
• Style settings, so drafts sound like you.

SPEND LESS TIME AND MONEY IN AI CHATS
• Checks that run on your device point out prompts that are missing details or likely to need a retry.
• Optimize tightens a long prompt and keeps every requirement you wrote.
• When a conversation gets too long, continue in a new chat with a short summary.
• Simple tasks such as arithmetic, unit conversions and word counts can run on your device instead of calling the AI.
• Model advice suggests a cheaper or stronger model from the ones you enabled. It never switches models without telling you.

REVIEW WORKSPACE
Save answers and selected text, compare and verify them, link sources, and record decisions. Everything is stored on your device, and you can export or back it up at any time.

PRIVACY AND CONTROL
• Your API keys stay on your device and are never added to web pages.
• Text is sent only to the AI provider you chose, and only when you ask for a result.
• WriteFlow never posts, sends or submits anything for you.
• No ads and no selling of data. Usage counts stay on your device and never include what you write.
