Source: OpenAI ChatGPT Watermark in 30 Seconds Announced October 5, 2026: OpenAI will add an invisible watermark to eligible ChatGPT and Codex text over the coming weeks. EU only. Outside the European Union, including the US and UK, ChatGPT text is not watermarked. API: opt-in for select models worldwide, off by default. Images are different: ChatGPT images already carry C2PA Content Credentials and a SynthID watermark in every country. No public detector. Only approved researchers get OpenAI’s text detector, and swapping 25% of words for synonyms drops detection from about 92% to 17%. For years the honest answer to “can anyone tell I used ChatGPT?” was “not reliably”. OpenAI has now said it will leave a machine-readable mark in ChatGPT’s text, but only where the law forces it to. ...

Summary: The 30-Second Answer Yes, Google Vids is free. Anyone with a Google account can generate AI video at vids.new on desktop. Since 23 September 2026 the model is Gemini Omni 1.1 Flash; before that it was Veo 3.1. The free limit is 6 AI video clips a month on a personal account, shared with AI avatars. Clips run 3 to 10 seconds, so the ceiling is about one minute of footage. Under Veo 3.1 it was 10. The “50” you keep seeing is credits, not videos. Personal accounts get 50 credits a month for voiceovers, images and drafts. Video clips come from the separate pool of 6. Google AI Plus adds nothing for video. It gets the same 6 clips. The first paid tier that helps is Google AI Pro at 500 seconds a month. Clips are 720p or 1080p, 24 fps, 16:9 or 9:16, with audio, and carry an invisible SynthID watermark. Gemini Omni 1.1 Flash, the video model that needs a Google AI subscription in the Gemini app, has been free inside Google Vids since 23 September. No card, no trial, just a Google account. ...

Summary: Gemini 3.8 TTS in 30 Seconds Yes, it is free to use. Both Gemini 3.8 Flash TTS and 3.8 Flash-Lite TTS are “Free of charge” on the Gemini API free tier, and you can use them in Google AI Studio with just a Google account. The catch: on the free tier, Google uses what you submit to improve its products, and human reviewers may read your inputs and outputs. Outside the EEA, Switzerland and the UK, keep private text and voices off the free tier. Free limits are not published. Google shows your per-model rate limits inside AI Studio, not in the docs. Paid pricing: about $0.81 per hour of audio with Flash TTS and $0.54 with Flash-Lite, at launch prices that run until December 31, 2026. On January 1, 2027 they double. Voice cloning works from a roughly 30-second sample, but only with a spoken consent recording from the voice’s owner. Commercial use: Google does not claim ownership of generated audio. You are responsible for how you use it. Google shipped two new text-to-speech models on September 23, 2026, and announced them in a launch post: Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS. They follow Gemini 3.8 Flash and the Gemini 3.8 Live API, and they do three things: read your script aloud, design a brand-new voice from a text description, and clone a real voice from a short recording. ...

Summary: Claude's Watermark in 30 Seconds Claude models released on or after August 2, 2026 embed an imperceptible mark in the text they generate. Older models are being retrofitted. The mark lives in the text itself. It survives copy and paste, and can survive light editing. Files get a separate mechanism: .svg, .png and .jpg outputs carry signed provenance metadata following the C2PA standard. Coverage is broad: the API, Claude apps, Claude Code, Cowork, Claude Tag, plus access through AWS, Google Cloud and Microsoft Foundry, worldwide. A detected mark means the content may have been processed by Claude. The absence of a mark proves nothing about whether text was AI-generated. Detection tooling and technical documentation are not published yet. Today, no third party can actually verify a mark. Watermarking an image is easy. You nudge millions of pixel values by amounts no eye can catch, and you are done. Watermarking text is a different problem entirely. There are no pixels, only words, and you cannot change a word “slightly”. It is either that word or a different one. ...
