What's an AI productivity tool?
AI productivity tools are small, focused helpers that use AI patterns to save you time on everyday tasks — drafting prompts, counting tokens, rewriting sentences, generating hashtags, and more. Each tool here runs entirely in your browser, so your data stays private.
1. Prompt Generator
Combine a role, tone, and task into a complete prompt ready for ChatGPT, Claude, or any LLM. Saves time on the boring part of writing AI instructions.
2. Token Counter
Estimate how many tokens your text uses (GPT-4 / Claude approximations) so you stay within context windows and budget API costs.
3. Sentence Rewriter
Apply a style (professional, casual, concise, engaging, formal) to your text. Our heuristic rewriter transforms common patterns to match the chosen voice.
4. Email Subject Generator
Get multiple subject line ideas in different tones. Open rates often come down to the subject line — give yourself options.
5. Hashtag Generator
Generate a mix of popular and niche hashtags for Instagram, TikTok, or YouTube based on your topic.
6. Word Counter
Live counts of words, characters, sentences, and estimated reading time.
