Get More From Google Antigravity Using a Memory Hub

Google Antigravity can plan, edit code, run tools, and manage development work inside an agentic coding environment. A productive conversation may contain architectural decisions, completed tasks, rejected approaches, and the exact next step for the project. If that conversation becomes unavailable, the repository may remain intact while the reasoning and project state become difficult to recover.
Memside gives Antigravity a separate place to save the parts of a session that should continue. Checkpoints can record current project state, Notes can preserve decisions and investigation results, and Tasks can hold unfinished actions. The goal is not to copy every chat message, but to keep enough verified context for a new session or another AI to continue safely.
When Antigravity chat history is unavailable
Antigravity chats may sometimes become difficult to find after an unexpected application closure, operating system restart, SSH reconnection, or software update. Conversation history may be missing from the interface even when project plans, files, or task records still exist locally. If this situation occurs, a separate project checkpoint can make it easier to understand the last confirmed state.
Conversation files or the local history index may also become unavailable or fail to show an earlier session correctly. This does not mean every Antigravity installation will experience the same problem. It does show why important project state should have a durable record outside one local conversation index.
A missing chat and a missing project are not the same problem. Source files, tests, commits, and local planning artifacts may still show what changed, but they may not explain why a decision was made or what remained unfinished. A Memside checkpoint adds that project-level explanation without attempting to replace the repository.
Connect Antigravity and save useful state
Antigravity can connect to Memside through the remote MCP endpoint at 'https://api.memside.com/mcp/'. The connection uses a Memside API key in the authorization header, and the key should be entered only in the trusted MCP configuration. Current setup instructions are available in the Memside Antigravity guide.
After the connection works, the first useful record is a project Subject. Related checkpoints, design Notes, Tasks, Facts, and operating rules can be connected to that Subject. This keeps the project state organized without turning every temporary debugging message into permanent memory.
Antigravity quota usage can rise quickly, especially when startup context is large or many project files are repeatedly referenced. A new session may also spend context rebuilding the goal, earlier decisions, completed work, and current task. A compact Memside checkpoint can help reduce some of that repeated startup context by loading the selected project state instead of a long conversation summary.
Memside cannot control which files Antigravity reads, change model pricing, or remove quota limits. It can help keep the initial request focused by providing the current goal, confirmed decisions, relevant files, and next task in a smaller record. This may reduce avoidable context use, although the actual quota consumed still depends on Antigravity, the selected model, the repository, and the work being performed.
Useful checkpoints should be created at natural milestones. Examples include completing the plan, finishing a database change, validating an API endpoint, resolving a difficult bug, or stopping work for the day. The following request can capture the required state.
Save a Memside checkpoint with the current goal, completed work, decisions, changed areas, test results, blockers, and next task.
Resume a project in a new Antigravity session
Consider an inventory application with an incorrect stock total. Antigravity inspects the code, identifies a duplicate event handler, changes two files, and confirms that the focused test now passes. Before the session ends, it saves a checkpoint with the root cause, changed files, test command, result, and one remaining regression check.
If the original conversation later disappears from the sidebar, a new Antigravity session can begin with the repository and the saved checkpoint. The new agent checks the recorded state against the current files and runs the listed test before continuing. This is safer than assuming the checkpoint alone proves that the code still matches the saved description. The resume request can remain simple.
Load the latest Memside checkpoint for the inventory project, verify it against the repository, and continue with the recorded next task.
Memside cannot recreate tool output, unsaved reasoning, or chat messages that were never stored. It also cannot repair Antigravity's local conversation database or restore a corrupted interface. It helps by preserving selected project state before a failure, making a fresh start faster and more accurate.
Switch to another AI for review or continuity
An Antigravity project may need a second opinion on architecture, security, testing, or product behavior. The current agent can save a review checkpoint with the expected outcome, completed changes, known risks, and unresolved questions. ChatGPT, Claude, Codex, or another connected AI can load that checkpoint without receiving the complete Antigravity conversation.
This is also useful when Antigravity is temporarily unavailable or its model quota has been reached. Another connected AI may not be able to edit the local repository, but it can review the saved plan, examine pasted code, organize remaining work, or identify questions for the next coding session. Availability and capabilities depend on the selected AI tool, so the review should clearly separate project context from verified code access.
If the reviewing AI is not connected to Memside, the checkpoint or a Memory Bundle must be copied into the new conversation. A non-connected service cannot retrieve private Memside memories by itself. The shared record still provides a focused review brief without requiring a raw chat export.
Keep checkpoints small and dependable
Saving too much creates another form of context clutter. The most useful checkpoint contains the current objective, confirmed decisions, completed work, blockers, verification evidence, and next task. Background research can remain in separate Notes, while stable project details can be stored as Facts connected to the project Subject.
The checkpoint should also distinguish between confirmed and assumed information. A passing test, committed file, or verified endpoint can be recorded as evidence, while an untested idea should remain a proposed next step. This makes it easier for a fresh agent to understand what is known and what still requires checking.
Google Antigravity already stores project and conversation data for its own workflows. Memside adds a portable continuity record that can be used outside that individual session and across other supported AI tools. When conversations are missing, corrupted, too long, or simply hard to resume, the saved project state provides a practical place to continue.
