Details

This app allows you to easily organize paper documents, notes, web links, etc. that you receive in your daily interactions, and share them smoothly with everyone in your group.

■What you can do with Postock

① Organize documents
Take a photo of paper documents or handouts with your smartphone and save them neatly as is. PDF is also supported.

② Share notes
You can share small messages, contacts, memoranda, etc. with your group.

③ URL bookmarks
Bookmark sites and documents that you think might be useful and look them over later with everyone.

④ Organize by category and tag
You can save information by adding categories and tags to make it easier to organize.

⑤ Share information with groups
Information can be delivered only to group members. You will receive a notification when you post, so you can prevent it from being overlooked.

⑥ Private management
You can manage notes and links that you don't want to share in your own space.

⑦ AI summary
AI automatically summarizes the contents of the documents you photographed. It's useful when you want to check them quickly.

■Features of Postock

-Simple and easy-to-use screen design
A design that anyone can use without hesitation.

-Delivers information properly only to those who need it
Specialized for sharing information in groups, reducing missed or overlooked information.

-Can be checked at any time from your smartphone
You can immediately see the information you need even when you're out or on the move.

■Reason for development

Even if you want to share information with someone, it doesn't get across well if you only communicate through paper or messages.
Postock was born out of a desire to reduce such situations where "you want to communicate but can't get it across."

Family, team, club, project, etc.
We aim to create an app that can be used just right in any situation where multiple people handle information.
