journaling made effortless

place for your whole thinking life

Your best ideas deserve better than a forgotten tab.

Most people aren't bad at thinking. They just don't have a system that makes thinking easy.

Thoughts disappear as fast as they arrive

You write it in Notes, voice memo it in the car, scribble it on a receipt. By morning, most of it's gone — or buried somewhere you'll never look again.

Journals start strong, then stop

You've started three this year. The habit never sticks because the tool makes it feel like work. There's no AI to help you develop an entry — just you and a blank page.

Your notes don't connect

You know you wrote something about this once. It's in there somewhere. But finding it — and connecting it to what you're thinking about now — takes longer than just starting over.

One place to think, write, and remember everything that matters.

Cleve turns your scattered thoughts into a second brain that actually works.

Personal Context

Your mind, organized once and useful forever

Write in your own voice, organize naturally, and let AI surface what's relevant when you need it. Your context builds up over time — and gets more useful as it grows.

Writing Made Easy

From raw thought to developed writing in seconds

Dump ideas, draft entries, write essays. Cleve helps you develop a rough thought into something worth keeping — no blank page, no pressure, no friction.

Cleve

From scattered thoughts to a working second brain

Write without friction

Open Cleve, write what's on your mind. Journal entries, rough ideas, half-formed thoughts — no templates, no pressure. Just you and your thinking.

Let AI help you go deeper

Ask questions, explore threads, turn a rough note into something worth sharing. AI that knows your context, not just your query.

Build a second brain that compounds

Over time, your notes connect. Patterns emerge. What you wrote three months ago becomes useful today. The more you put in, the more you get back.

Security

Enterprise-grade security and privacy.

Your docs, notes, ideas, thoughts and sensitive work should never be used to train AI models, and should be protected. Cleve offers industry-leading practices in ensuring your data is secure. Learn more.

Never used to train AI models

None of your data is ever used to train AI models in Cleve, making it more secure than using ChatGPT, Claude or Gemini directly, where model training is default-on.

Encrypted everywhere

Everything you store is encrypted at rest using AES-256. All connections use TLS 1.2 or higher, including every call to an AI provider.

Prompts never stored

When you use an AI feature, your prompt is sent, a response is returned, and nothing is stored on the provider's side. We don't allow providers to hold onto it.

SOC 2 Type II infrastructure

Every service that processes your data (database, authentication, payments, file storage) is independently security-audited and SOC 2 Type II certified.
