Stop Typing Prompts.
Start Speaking Code.
CoScript is the voice-to-text engine built for the agentic era. Dictate architecture, debug verbally, prompt engineer at 150 WPM, and paste directly into Cursor, VS Code, terminal, or any AI tool.
You already talk to yourself while coding. Now it writes itself down.
The Problem
You're building with AI agents. You spend 40% of your day writing prompts — not code. Every interaction with Cursor, Claude, or ChatGPT starts with a lengthy text input that you type at 50 words per minute.
Meanwhile, you speak at 150 words per minute. Your brain is 3x faster than your fingers. Every minute you spend typing a prompt is 40 seconds wasted.
CoScript eliminates that gap. Press F9, speak your intent, press F9 again. Clean, structured text appears wherever your cursor is — in under a second.
Developer Workflows
Dictate Your Architecture
Speak your system design out loud. CoScript transcribes your thinking into clean, structured text that you can paste directly into a PRD, GitHub issue, or AI agent prompt.
"Okay so the auth flow needs to hit the middleware first, validate the JWT, check if the session is expired, and if it is, redirect to the refresh token endpoint before retrying the original request."
The auth flow hits middleware first → validates JWT → checks session expiry → redirects to refresh token endpoint → retries original request.
Debug by Talking Through It
Rubber duck debugging, but the duck writes everything down. Speak your hypothesis, CoScript captures it, and you paste it into your AI coding assistant for instant analysis.
"The race condition is happening because the WebSocket handler fires before the database write completes. I think we need to await the Firestore set call before broadcasting the event."
Root cause: WebSocket handler fires before DB write completes. Fix: await Firestore set() before broadcasting the event.
Prompt Engineer at the Speed of Speech
Stop typing 200-word prompts. Speak your intent naturally, switch to Prompt Mode, and CoScript restructures your words into an optimized AI prompt — ready to paste into Cursor, Claude, or ChatGPT.
"I need a Next.js API route that accepts a POST with a JSON body containing a user ID and returns their last 10 transactions from Stripe, sorted by date."
Create a Next.js API route (POST) that accepts {userId: string} in the request body. Query the Stripe API for the customer's last 10 charges, sorted by created date descending. Return the array with id, amount, currency, status, and created fields. Handle authentication errors and rate limiting.
Document as You Build
Write README files, API docs, and changelogs by speaking. CoScript's Clean Mode removes filler words and corrects mid-sentence changes, producing publish-ready documentation instantly.
"This endpoint accepts a — wait no, it returns a paginated list of all active subscriptions. Each object contains the subscription ID, the plan name, and the... uh... the renewal date."
This endpoint returns a paginated list of all active subscriptions. Each object contains the subscription ID, plan name, and renewal date.
Who Uses CoScript
AI Agent Builders
Dictate complex multi-step prompts, system instructions, and agent architectures. Stop typing thousand-word prompts — speak them in 30 seconds.
Cursor / Windsurf / Copilot Users
CoScript is the missing voice layer. Press F9, describe what you want built, and paste the optimized prompt directly into your AI coding assistant.
Technical Writers
API documentation, README files, architecture decision records — speak naturally and get clean, professional technical prose without typos.
Content Creators & DevRels
Script YouTube tutorials, conference talks, and blog posts by dictating. Content Mode reformats your speech into engaging, publish-ready copy.
Remote Engineers
Compose detailed Slack messages, PR descriptions, and Loom scripts 3x faster. Perfect for async communication in distributed teams.
Indie Hackers & Solo Founders
You're building alone — every minute counts. Dictate user stories, landing page copy, investor pitches, and customer emails without breaking your flow.
Under the Hood
On-Device Whisper AI
English transcription runs locally via faster-whisper with int8 quantization. Sub-second inference on any modern CPU. Zero cloud latency. Works offline.
Gemini 2.5 Flash Cloud
Non-English languages and AI modes (Email, Brainstorm, Prompt Engineer, Content) route through Google's Gemini 2.5 Flash for 100+ language support and intelligent restructuring.
OS-Level Injection
CoScript operates at the operating system level — not inside a browser or IDE. Global hotkey → clipboard write → Ctrl+V into whatever window has focus. Works everywhere.

Developer FAQ
How does CoScript help with agentic AI development?+
CoScript lets you dictate complex prompts, architecture decisions, and debug hypotheses at the speed of thought. Instead of typing lengthy prompts for Cursor, Claude, or ChatGPT, you speak naturally and CoScript transcribes, cleans, and pastes directly into your editor or terminal. The Prompt Engineering mode automatically optimizes your spoken words into structured AI prompts.
Can CoScript paste directly into VS Code, Cursor, or terminal?+
Yes. CoScript works at the OS level — it captures your voice with a global hotkey (F9), transcribes locally using on-device AI, and pastes the result directly into whatever application has focus. VS Code, Cursor, terminal, Slack, Notion, browser — anywhere you can type, CoScript can paste.
Does CoScript work offline for developers?+
Yes. CoScript's core English transcription runs entirely on-device using a local Whisper AI model. No internet required. Cloud features like translation and advanced tone modes require connectivity, but raw dictation and code documentation work fully offline — even on airplanes.
Is CoScript free for developers?+
CoScript offers a free tier with 3,500 words per week of local AI transcription — enough for most individual developers. Pro plans start at £12.99/month for unlimited local AI and 50 hours of cloud AI features like translation and advanced modes.
How is CoScript different from GitHub Copilot Voice?+
CoScript is not IDE-specific — it works across your entire OS. While Copilot Voice is limited to VS Code commands, CoScript transcribes anywhere: into prompts for Cursor, documentation in Notion, messages in Slack, terminal commands, commit messages, and more. It also supports 100+ languages and 30+ professional tones.
Can I use CoScript for prompt engineering?+
Yes. CoScript has a dedicated Prompt Engineering mode that takes your spoken idea and automatically restructures it into a highly optimized AI prompt. Speak your goal naturally, and CoScript outputs a prompt ready to paste into ChatGPT, Claude, Cursor, or any AI tool.
