Titles, descriptions, tags, thumbnail ideas — all at once. Bring your own API key, keep full control.
Stream Jarvis helps YouTube creators generate complete content kits in seconds — titles, descriptions, tags, hashtags and thumbnail prompts, all powered by AI. Bring your own API key from Google Gemini, Groq, or OpenAI and generate unlimited content at zero cost.
Every title comes with a live character counter so you never exceed YouTube's 100-character limit. Descriptions are written like real creators — no robotic timestamps or essay openers. Tags and hashtags are generated in bulk, optimized for discoverability.
Get three detailed image generation prompts per video, ready to paste into Midjourney, DALL-E, Leonardo or Ideogram. Each prompt includes composition, lighting, color palette, text overlay and style — everything an AI image tool needs.
Yes. Stream Jarvis itself costs nothing. You use your own API key from providers like Google Gemini or Groq, both of which have free tiers with no credit card required.
Your API key is stored only in your own browser's localStorage. It never touches our servers. Every request goes directly from your browser to the AI provider you chose.
Stream Jarvis supports Google Gemini, Groq, OpenAI, OpenRouter, HuggingFace and Mistral AI. Keys are auto-detected the moment you paste them — no manual selection needed for most providers.
No account, no signup, no login. Open the page, paste your API key, and start generating immediately.
Five YouTube title options with character counters, an SEO-optimized description, 20 tags, 10 hashtags, and three detailed thumbnail image prompts. Every section can be individually regenerated or copied with one click.
