for your AI chats.

We hope to offer a more comfortable environment for your daily work. Use folders, tags, and search to replace that long flat list, and let our little AI assistant help you tidy up your history. Everything runs locally in your browser, quiet and secure.

02  /  why we built this

As time goes by, we found that the long, flat chat list becomes increasingly difficult to manage.

01
Finding a great conversation from last month can often take quite a bit of scrolling.
02
Carefully crafted prompts are sometimes hard to locate again without a proper place to keep them.
03
When you want to find a specific thought buried deep in a message, limited search can feel a bit frustrating.

We created Better Sidebar hoping to provide a slightly better way to organize. You can use folders and tags to sort your ideas, full-text search to retrieve memories, and an AI assistant to help share some of the tedious sorting work.

Type > and let it help you.

After some exploration, we’ve added a small feature: an AI assistant. It understands your local data and can help with consecutive tasks. Since it runs locally using your current Gemini session, it requires no API keys and sends no data outside.

no api keysyour own sessionmulti-stepeasily reversible
safety first
We respect your data. All write operations will wait for your explicit approval before executing, while reads run smoothly.
If you find it reliable, you can enable Speed Mode to reduce interruptions. Don’t worry, you can always undo its actions.
Its status rests quietly above your input box, keeping you informed and giving you the control to stop it at any time.
If it encounters an issue or gets stuck, it will pause automatically and honestly report the reason.

01
auto-organize
If you’d like, it can read titles, build categories, and neatly file your recent chats into folders with tags.
02
backfill search index
Due to platform limits, older chats might not be fully recorded. This feature helps sync your history so search and exports are complete.
03
query your own data
You can chat with it like a friend, asking for stats and details about your own conversation history.
04
prompts & snippets
We hope this saves you a little time by helping you rewrite, rearrange, and deduplicate your prompts in bulk.
05
custom skills
If you have specific habits, you’re welcome to define your own custom workflows in the settings so it can serve you better.

A few small designs that might bring some convenience.

01  /  search

Search the content, not just titles.

You can perform full-text searches across all your history by combining keywords, tags, or platforms. You can also scope it to your active chat if needed.

02  /  prompts

Keep your prompts safely organized.

Store your frequently used prompts in one place with variables. Simply type / to summon them without leaving the input box, making your workflow smoother.

You can export your chats perfectly formatted as Markdown, plain text, or JSON. If you prefer Notion or Obsidian, we offer support for those too (Power Pack).

Organize your thoughts with colors.

You can assign different colors to folders and tags to make sorting more intuitive. New chats from Gems and Notebooks can also automatically find their designated homes.

Please rest assured, your data remains yours.

01
local by default
The database runs entirely locally within your browser. We have no servers to receive your data.
02
no collection
We do not collect, store, or transmit your chat content or any personal settings.
03
no training
We deeply respect your privacy and will never read your conversations for model training or any other purpose.
04
minimal permissions
Permissions are strictly limited to the necessary domains. We cannot see any of your other browsing activities.

Because we need to adjust the interface and read titles for sorting, your browser will request permissions for these domains upon installation. This is only to let the extension function properly. Your data is kept locally, or synced through your own Google Drive.
