ZeroTwo stores all your conversations in the left sidebar, organized chronologically and by project. Your history persists indefinitely unless you manually delete conversations or delete your account. It is server-side, so it syncs across every device and browser you use.

Where Your History Lives

Your chat history is in the left sidebar, organized into time-based sections with a Pinned section at the top:
SectionWhat’s Included
PinnedChats you have explicitly pinned — always at the very top
TodayChats with any activity in the last 24 hours
YesterdayChats last active the previous calendar day
This WeekChats from the current week, not covered by Today or Yesterday
OlderAll conversations before the current week, newest first
Project chats appear in separate collapsible sections below the main history — one section per project. Click any project name to expand or collapse it. Project chats are distinct from your standalone chat history and are always associated with that project’s context.
Chat history is private by default. Only you can see your conversations. On Business plans, org admins may have visibility into member activity per the organization’s policy.

Finding Old Chats

The fastest way to find a specific past conversation is the search bar at the top of the left sidebar.
1

Click the search bar at the top of the sidebar

The search input is above the Pinned section. Click it to activate.
2

Type your query

Type a keyword, phrase, topic, or model name. ZeroTwo searches both chat titles and conversation content in real time as you type.
3

Review the results

Matching chats appear in the search results. Each result shows the chat title and, where relevant, a content snippet indicating where the match occurred.
4

Click a result to open it

Click any result to open that conversation in the main area. Press Escape to dismiss search and return to the normal sidebar view.
Search is the fastest way to find old chats. If searching by the obvious keyword does not work, try a different angle — a specific phrase the AI used, the model name you were using, or a term from the response content rather than your original question.

Chat Titles

Chat titles are auto-generated from the content of your first message — ZeroTwo creates a short, descriptive 5–7 word summary automatically. For example: “Refactor auth middleware Node.js” or “Q3 marketing campaign strategy.” To rename a chat: Right-click the chat in the sidebar → Rename → type the new name → press Enter. Having meaningful titles makes search much more effective. If you frequently start chats with short or generic opening messages, renaming them immediately after creation keeps your history navigable.

Pinned Chats

Pinned chats stay at the top of the sidebar indefinitely, regardless of when they were last active. Useful for:
  • Ongoing reference conversations you return to frequently
  • Active projects or threads you need quick access to
  • Chats with important context or decisions you want one click away
To pin a chat: Right-click it in the sidebar → Pin. To unpin: Right-click the pinned chat → Unpin.

Project Chats

Chats created inside a project appear under that project’s section in the sidebar. They are:
  • Associated with the project’s instruction set (system prompt)
  • Included in the project’s file library context
  • Accessible via the sidebar project section or by navigating to /projects/:id
  • Separate from standalone chat history
If a project is deleted, all its associated chats and files are also deleted. See Projects Overview for more on project management.

Persistence and Retention

ZeroTwo retains your full conversation history as long as your account is active. There is no automatic expiration, time-based pruning, or storage cap on history. History persists across:
  • Device and browser changes — history is server-side, not stored locally
  • Session resets and logouts
  • Plan changes — upgrading or downgrading does not affect your history
History is removed only when:
  • You manually delete individual conversations
  • You use bulk delete via Settings → Data Controls → Clear Conversations
  • You delete your account

Exporting Chat History

To keep a backup of your conversations or move your data:
1

Open Settings

Click your profile avatar at the bottom of the left sidebar, then select Settings.
2

Navigate to Data Controls

In Settings, click Data Controls in the left navigation panel.
3

Click Export Data

Click the Export Data button. ZeroTwo prepares a structured download of your full conversation history.
4

Download your export

The export is made available as a direct download or sent to your registered email address. Save it to a secure location.
The export includes all conversation content in a structured format. See Data Export and Deletion for full details on what is included.

Finding an Old Chat: Strategies

If you cannot find a conversation through the search bar alone, try these strategies in order:
  1. Search by keyword — use the sidebar search for words you remember from the conversation
  2. Search by topic — try broader terms related to the subject or task
  3. Search by model name — if you remember which model you used, search that
  4. Browse by time period — scroll to the Older section and look in the approximate date range
  5. Filter by project — if the chat was part of a project, look under that project’s section
  6. Export and search — export your full history and search the exported file for content that is hard to find in the UI
