Ancroo

Point. Prompt. Done. An AI prompt launcher for any page — run prompts with your own LLM, no tab switching.

Ancroo is an AI prompt launcher for your browser. Select text on any page or type input manually, fire an AI prompt, and get results right where you need them. No tab switching. No copy-paste. SETUP IN SECONDS Connect to OpenAI, Anthropic, Google Gemini, Ollama, OpenRouter, or any OpenAI-compatible API. Add your API key, pick a default model, and you're ready. To get you going, eleven ready-made actions are set up instantly — a starting point you can edit, rename, or replace with your own: - Summarize - Translate to English - Rewrite Formal - Explain - Fix Grammar - Fix Capitalization - Draft Reply - Polite Decline - Thank-You Note - Convert to Markdown - Ask AI MAKE IT YOURS These eleven are just examples. The real power is building your own: write a custom prompt and system prompt, pick the model (the editor auto-detects available models from your provider), choose how input and output work, and assign a hotkey — for exactly the tasks you do every day. TRY THE STARTER ACTIONS Once installed, open our practice page and put the starter actions to work right away. Select sample text, form fields, code, or example emails, open the side panel, and run an action to see Fix Grammar, Translate, Draft Reply, and more in action — including replace-in-place and show-in-panel outputs. → https://ancroo.github.io/ancroo-web/ POINT.
