OpenAI Platform

What is OpenAI Platform?
OpenAI Platform is where developers sign in to build with the OpenAI API, including the Playground for live prompt tests. The login page links out to developer docs, the API reference, starter sample apps, and OpenAI cookbooks for implementation patterns.
ChatGPT handles consumer conversations, while OpenAI Platform targets builders who need API keys, model parameters, and reproducible test runs before shipping code. The Playground URL in this listing is the interactive shell for trying completions without writing an app first.
Software engineers, ML engineers, and product teams prototyping LLM features use OpenAI Platform to validate prompts, compare model settings, and jump into official docs from one signed-in hub. SSO covers Google, Apple, Microsoft, and phone login alongside email.
Lightkey

What is Lightkey?
Lightkey learns how you type on Windows and suggests the next words while you write in Office apps or the browser. Accept a prediction with Tab and keep drafting emails, documents, and chat replies without stopping to fix typos.
Cloud writing assistants send keystrokes to remote servers, which is a non-starter for legal, healthcare, and enterprise drafts. Lightkey keeps prediction on your machine, supports 60-plus industry content domains, and offers a business tier with team terminology, which is the trade-off worth knowing if privacy matters more than cross-device sync.
Writers, support reps, and office teams use it in Word, Outlook, Gmail, Slack, Notion, and ChatGPT on the web. A free tier handles basic prediction, while Lightkey Pro unlocks unlimited suggestions and productivity metrics.
