EsTime: AI Project Estimates

"How long will this take?" Estimating the time a project needs is the hardest part of your job — and the most expensive to get wrong: underestimated hours, deadlines that slip, and quotes that fall short.

EsTime fixes that. Using artificial intelligence (AI), it breaks any project down into tasks with their hours in seconds, so you can plan and quote with confidence from day one. And it's much more than a calculator: it learns from every project you finish and sharpens the next estimate — more accurate than the last, and tailored to how you actually work. Stop guessing and start estimating with data.

HOW IT WORKS
1. Describe your project — "a landing page with a hero, features and a contact form."
2. Review the AI's task breakdown and adjust anything you like.
3. Work through it and log your real hours. When you finalize, EsTime learns.

BUILT TO LEARN FROM YOU
• Every task carries a tag (design, copywriting, API…) and a complexity, from Trivial to Very complex.
• EsTime keeps a personal hours-per-tag model and refines it every time you finish a project.
• Once it has seen enough of your work, it shows a confidence range instead of a single number.
• Big projects get an automatic buffer for the context-switching that always creeps in.

FEATURES
• AI project estimates from a plain-text description
• Personalized hour estimates that improve with every finished project
• Configurable routine tasks: set them once (meetings, email, admin…) and they're added automatically to every new project, counting that invisible time without skewing the learning
• Tag dictionary: rename, merge, archive and fine-tune hours
• One-off tasks specific to a single project
• A quick profile at the start, so your very first estimates already fit your field
• Works offline — your projects live on your device

And this is just the beginning: EsTime keeps adding features release after release.
