A good idea rarely arrives fully formed. It starts with a thought, then another—often when you're busy doing something else.

First Thought gives you a place to capture those moments and bring them together. Save a new idea, add a thought to something you're already working on, or jot down a to-do. You don't have to organize everything before you write it down.

Capture now. Keep thinking.
Write what's on your mind and let First Thought help find where it belongs. It looks for connections with your existing ideas and files clear matches. When it isn't sure, your thought stays saved, with a suggestion you can choose to accept. You can always change where something goes.

Give your ideas room to grow.
Keep the notes, questions, and to-dos behind an idea together as it develops. Browse a visual library of idea cards, find a thought with search, and organize work around your projects. An unfinished idea is welcome here. So is one you're saving for another day.

See what connects.
Explore a visual map of your ideas and discover relationships you might otherwise miss. One thought can belong to several ideas without being copied, so a useful insight doesn't have to live in just one place.

Your thoughts. Your choice.
Capture and organize on your device, even offline. Sorting works on your phone on its own; if you want sharper filing you can turn on AI sorting, and the app shows you exactly what it sends. Anything marked Local only stays on that device — outside cloud sync, and never sent to any AI. Mark an idea or thought Local only to keep it on that device, outside cloud sync.

Pick up where you left off.
Use First Thought on your phone, then open it in a web browser on your laptop or computer. Sign in to the same account and your synced ideas and thoughts follow you. Local only material stays on its original device.

Take the next step when you're ready.
Turn your idea into a clear brief with Prompt Studio. Choose the thoughts and details to include, then copy the result to an AI assistant if you want help developing it. Creating a brief happens locally; sharing it is your choice.

Keep a copy of your own.
Export a backup of your library, including Local only material, and restore it when you need to.

Made for creatives, makers, writers, and anyone with more ideas than places to put them.

First Thought. Never lose a good idea.
