Frequently asked questions

Everything you need to know about SnapKit, ChatGPT screenshot generation, and using mockups for marketing.

General

SnapKit is an API and MCP server for generating pixel-perfect screenshots that look like real social media and platform UIs. Send structured JSON, get back a PNG. No browser automation, no design tools, no manual screenshotting.

SnapKit currently supports ChatGPT, Reddit, LinkedIn, and Instagram screenshot generation. Facebook and Twitter/X templates are coming soon.

Send a POST request to /api/v1/render/{template} with your content as JSON. The API validates the payload, renders the screenshot server-side, and returns a high-resolution PNG. You can also connect via MCP server for agent-native workflows.

Marketers creating ad creatives and social content, developers building tools that need UI screenshots, and AI agents that generate visual content programmatically. The API is designed to be consumed by both humans and machines.

Free tier with no account required. Premium unlocks higher-resolution exports, watermark-free downloads, and additional customization options.

Yes. SnapKit creates mockups — the same way designers use Figma to mock up UI screens. You control every word, so the output is your content in a familiar visual format. Check each ad platform’s creative policies before publishing.

No. SnapKit is a hosted API. You make an HTTP request and get an image back. There’s nothing to install or run locally.

Yes — that’s a first-class use case. Connect via MCP server or call the REST API directly. Any agent that can make an HTTP request or speak the Model Context Protocol can render screenshots with SnapKit.

ChatGPT screenshots

The easiest way to make a fake ChatGPT screenshot is with a dedicated generator tool like SnapKit.ai. Type both sides of the conversation, select light or dark mode, and export a PNG without needing a ChatGPT account or design software.

A fake chat generator is a tool that creates realistic-looking chat conversation screenshots by letting the user write both sides of the dialogue without needing a live account or active conversation. ChatGPT screenshot generation is the highest-demand use case due to the growth of AI content in marketing, but social platform mockups are increasingly used for ad creatives, tutorials, and content demos. SnapKit currently supports ChatGPT, Instagram, Reddit, and LinkedIn, with additional templates rolling out next.

No. SnapKit generates the screenshot entirely from your JSON input. There is no connection to OpenAI’s servers, no API key required, and no ChatGPT account needed. You write both sides of the conversation and SnapKit handles the visual rendering.

Yes. With SnapKit you write both sides of the conversation, giving you complete control over the user prompt and the AI response. This makes it ideal for marketing content, client demos, and educational examples where you need a specific, predictable AI output every time.

SnapKit.ai is built for pixel-accurate ChatGPT screenshot generation, replicating the platform’s current fonts, message bubble dimensions, spacing, avatar placement, and color schemes for both light and dark mode.

SnapKit gives you full control over every message, pixel-perfect visual accuracy, and instant high-resolution exports — without needing a ChatGPT account. Real ChatGPT screenshots depend on unpredictable AI responses, require an active subscription, and often need manual cropping or editing before they are usable in ads or content.

Yes. SnapKit supports both light mode and dark mode, accurately matching ChatGPT’s current interface design in both themes. You can toggle between modes before exporting, so your screenshot matches the visual style you need for your ad or post.

Currently SnapKit supports single-turn conversations — one user prompt paired with one AI response. This covers the vast majority of use cases including ads, social posts, and educational content. Multi-turn support is on the roadmap.

High-resolution PNG at 2× pixel density. PNGs preserve sharp text rendering and are universally supported across social platforms, ad managers, presentation software, and web browsers. The default canvas is 800×600 but fully configurable via the API.

Marketing & ads

AI conversation screenshots act as visual social proof that feels authentic and trustworthy. They combine the authority of AI with the relatability of a natural conversation, making them ideal for ads, landing pages, and social content. Marketers report higher engagement rates compared to traditional static creatives because the conversational format draws readers in.

The conversation format triggers curiosity. Users are conditioned to read chat interfaces, so the format feels like content rather than advertising. This bypasses ad fatigue and drives higher click-through rates because people want to see the full response. The perceived authenticity of an AI conversation creates trust that traditional ad creative cannot replicate.

You can use ChatGPT screenshot creatives on Facebook, Instagram, TikTok, LinkedIn, Twitter/X, Pinterest, and Google Display Network. The PNG format is universally supported. Always check each platform’s current creative policies before launching campaigns — guidelines around AI-generated content vary and update frequently.

Any size from 400x400 to 1920x1920 pixels. Common ad dimensions include 1080x1080 for Facebook and Instagram feed ads, 1080x1920 for TikTok and Instagram Stories, and 1200x627 for LinkedIn sponsored content. You specify the exact width and height in the API request.

Yes. Use vertical 1080x1920 dimensions for TikTok ads. The full-screen format is ideal for hook-style ChatGPT conversations that stop the scroll. Keep prompts short and provocative, and let the AI response deliver the value proposition.

Under 60 seconds. Script the conversation with your marketing message, pick your visual style (light or dark mode), and export as a high-resolution PNG. No design tools, no templates to configure — just structured JSON in, pixel-perfect image out.

No. SnapKit handles all the visual rendering — typography, spacing, avatars, and interface chrome are all pixel-perfect replicas of the real ChatGPT UI. You focus on writing the conversation copy, and SnapKit produces a production-ready image.

Unlimited. The API accepts different conversation data each time, so you can generate hundreds of variations for A/B testing in minutes. Change the prompt, the response, the model name, light or dark mode, and the dimensions to create unique creatives for every audience segment.

Absolutely. Create mockups that demonstrate AI capabilities, illustrate product use cases, or pitch creative concepts to clients. Agency teams use SnapKit to prototype ad creatives and social content before going into production.

Requirements for ChatGPT-style mockups vary by platform, jurisdiction, and how the asset is presented. SnapKit images are simulated screenshots, not actual ChatGPT outputs. Review the applicable platform policies and legal requirements before publishing, and disclose mockups where that distinction matters.
