Whether you need a quick reply, better wording, a grammar check, or help writing from scratch, AI Keyboard puts useful writing tools right where you type. KEY FEATURES • AI Keyboard: Access AI writing tools directly from your keyboard while typing messages, emails, social posts, and more. • Write with AI: Turn an idea or short prompt into a complete message, email, caption, or other text. • Smart Replies: Generate relevant responses when you’re not sure what to say or want to reply faster. • Rewrite & Improve: Make your text clearer, more natural, concise, or polished while keeping the original meaning. • Grammar & Spell Check: Fix grammar, spelling, and awkward wording before you send. • Change Your Tone: Make your writing sound professional, friendly, casual, confident, or appropriate for the situation. • Translate Text: Translate messages and other text when communicating in different languages. • Summarize: Turn long text into key points when you need a shorter version.

WHO IS AI KEYBOARD FOR?

CAN AI KEYBOARD HELP ME WRITE MESSAGES AND REPLIES? Yes. Create new messages, generate replies, or improve text you’ve already written for everyday chats, work conversations, emails, and social media. CAN I USE AI KEYBOARD FOR WORK AND EMAILS? Yes. Draft emails, improve grammar and wording, adjust tone, summarize text, and make professional communication clearer. CAN AI KEYBOARD HELP IF ENGLISH ISN’T MY FIRST LANGUAGE? Yes.

Propel is an AI-powered proposal management platform designed to help freelancers and teams create compelling project proposals faster. From a single project opportunity, Propel streamlines the entire proposal workflow—from AI-generated content and visual frame planning to final approval. Simply submit a project opportunity, and Propel automatically generates a professional proposal, a detailed frame description, and a real-world use case using intelligent automation. The frame description outlines how the final visual content should look, helping turn your approved concept into a set of AI-generated images. Review each item, request revisions when needed, and approve content before it moves to the next stage. ### AI-Powered Proposal Generation Generate high-quality project proposals in minutes using AI-powered workflows. Save time while maintaining a professional and personalized approach for every opportunity. ### Frame Description Generation Create detailed frame descriptions tailored to each project. These descriptions outline the visual composition, content, and direction for each frame, providing a clear plan for the images that will be generated. ### AI-Generated Frames Once the frame content is approved, Propel uses the approved descriptions to generate the corresponding visual frames as images. Generated frames can be reviewed and downloaded together as a ZIP file for convenient access. ### Real-World Use Cases Automatically generate relevant use cases that demonstrate your understanding of client requirements and strengthen your proposals. ### Review & Approval Workflow Review each generated component, request revisions when needed, and approve content before moving forward. Approving the frame descriptions initiates the frame generation process, keeping the workflow organized and controlled. ### Simple & Efficient Propel brings proposal creation, content planning, AI-generated visuals, and approval together in a clean, intuitive interface designed to improve productivity and consistency. Whether you're an independent freelancer or part of a growing team, Propel helps you prepare professional proposals and supporting visual content with confidence and efficiency.
