Project Ideas

You might notice that the ideas listed are sometimes vague or incomplete. This is on purpose, as in real-world development, you often need to define the problem and scope your solution before coding officially begins. If you wish to submit a proposal based on these ideas, you are encouraged to contact the mentors on Discord and find out more about the particular suggestion you're looking at.

Desktop features

  1. Table (it's taken)

Add simple tabular content to a page

Expected Outcome:

  • The user can insert a table into a page via the slash '/' command

  • The user can delete and duplicate an existing table

  • The user can add/delete/duplicate/update rows and columns to an existing table

  • Each table cell supports rich-text editing

  • Test covered

Difficulty: Medium to High

Skills Required: Flutter

  1. Calendar Database (it's taken)

Calendars are a great way to visualize how things connect to certain dates from any database in AppFlowy. Use them for task management and event planning.

  • Expected Outcome: the user can create a calendar page and add an item to a certain date or a range of dates in the calendar.

  • Difficulty: High

  • Skills Required: Flutter

  • Mentor: Nathan.fooo


  1. Themes (it's taken)

Control the accent color used for interactive elements such as links, handles, and text selection. The editor cursor can also choose to use the same accent color.

Other customizations:

  • Fonts

  • Font sizes, font weights

  • Font colors

  • Text background colors

Difficulty: Medium

Skills Required: Flutter

Mentor: Lucas

  1. Shortcuts (it's taken)

Add more shortcuts and enable users to customize hotkeys

Difficulty: Easy to Medium

Skills Required: Flutter

  1. AI writers (it's taken)

Utilize AI models to assist in writing. For example, generate to-do lists, outlines, and blog posts.

Difficulty: Medium

Skills Required: Flutter

Mentor: Lucas

  1. AI image generator

Generate images from text and beyond

Difficulty: Medium

Skills Required: Flutter

Mentor: Lucas


  1. Code Block for AppFlowy Editor (it's taken)

Develop a code block in Flutter as a standalone package that can be used by AppFlowy and other Flutter applications

Difficulty: Medium to Hard

Skills Required: Flutter

Mentor: Alex


  1. Outline Plugin for AppFlowy Editor (it's taken)

Adding the outline block to the document will automatically generate a list of anchor links to the headings within the document.

Expected Outcome:

  • insert an outline via the slash '/' command

  • convert highlighted lines into an outline

  • the content of the outline will be generated automatically based on the document

  • click on the content of the outline will take users directly to the corresponding heading

  • different levels of headings are indented differently. For example, H1 will have no indentation, while H2 will be indented once, and so on.

Difficulty: Medium

Skills Required: Flutter

Mentor: Lucas

  1. Favorites (it's taken)

Allow us to quickly access favorited pages via Favorites in the left navigation panel.

Expected Outcome:

  • Favorite and unfavorite a page or subpage

  • Favorited pages can be accessed from the "Favorites" list in the left panel

Difficulty: Hard

Skills Required: Flutter, Rust

Mentor: Mathias, Nathan

  1. Importers (it's taken)

Import data from third-party sources, eg: Notion importer, Joplin importer

Difficulty: Easy / Medium / Hard

Skills Required: Flutter, Rust

Mentor: Lucas

CI tools

1. Report Binary Size

We consider binary size as an important metric, although it is easy to overlook. We would like to create some GitHub integrations that would automatically do a release build of a new PR and report the difference in binary size between that PR and the current main branch.

  • Expected Outcome: an easy-to-use tool to report binary size

  • Difficulty: Easy / Medium

  • Skills Required: Flutter, Rust, GitHub API

  • Mentor: Nathan.fooo

2. Speed up building the release package

It takes almost 20 minutes to build the AppFlowy release package. It would be nice if we can speed it up using GitHub cache or matrix.

  • Expected Outcome: the cost of the time of the PRโ€™s GitHub actions should be reduced

  • Difficulty: Easy / Medium

  • Skills Required: Flutter, Rust, GitHub API

  • Mentor: Nathan.fooo

Tracing performance regressions

1. Tracing performance regressions

Performance could become a key differentiator for AppFlowy. Weโ€™d like to keep tracking it. To track it, we need to come up with a metric system. The system includes a set of metrics and a running process that collects results and persists them for analysis.

  • Expected Outcome:

    • A metric system that measures the performance of AppFlowy

    • A working tool that collects results and persists them for analysis

  • Difficulty: Medium / High

  • Skills Required: Rust

  • Mentor: Nathan.fooo
