The short answer
Perplexity has no native push to Gemini. You'll copy each Space's Instructions, download its Files, and rebuild as a Gem with Drive-stored Knowledge — instructions pasted into the Gem, files uploaded to a dedicated Drive folder. Plan 20–40 minutes per Space; Threads do not transfer. A shared MCP-based memory layer like MemoryLake lets both tools read the same source.
Why people switch from Perplexity to Gemini
Three drivers in 2026:
- Native Workspace pull. Gemini reads Drive, Docs, Sheets, Slides, and Gmail without re-uploading.
- Bundled access. Gemini comes with many Google One or Workspace plans.
- Multi-file synthesis. Long-input handling across many documents is a Gemini strength.
What "memory" means in Perplexity vs Gemini
Different surfaces.
Perplexity memory lives inside Spaces: each Space has its own Instructions, Files, and Threads. There is no global cross-Space memory.
Gemini memory spans Saved Info (short snippets, account-wide), Gems (custom personas with their own instructions and optional referenced files), and Past Chats / Activity (governed by Activity controls).
A Perplexity Space usually becomes a Gem reading from a Drive folder. Space Instructions become Gem instructions. Space Files become Drive folder contents.
Step 1: Export your Perplexity Spaces
Perplexity has no Space-export bundle.
- Copy each Space's Instructions. Open the Space → Settings → Instructions. Paste into a text file labelled with the Space name.
- Download each Space's Files. Open the Files area and download every file in its original format.
- Archive Threads (optional). Copy salient Q&A pairs from important Threads into Markdown.
- List collaborators. Note who had access — Gemini's sharing model differs.
End state: one folder per Space with instructions.txt, downloaded files, and any archived Threads.
Step 2: Import into Gemini
Gemini lands the import via Drive plus Gems.
- Upload exported files into Google Drive. Create a dedicated Drive folder per Gem; place the downloaded files inside.
- Create a Gem per Space. Open Gem Manager → New Gem.
- Paste Instructions as the Gem's instructions. Add a line telling Gemini which Drive folder holds the Space's content.
- Drop account-wide preferences into Saved Info. Gemini settings → Saved Info → Add.
- Validate. Open the Gem and ask a question that depends on a moved file.
Gemini reads Drive content live, so updates to the uploaded files propagate.
What you'll still lose after migrating
- Citation grounding. Perplexity's inline citations don't carry over.
- Thread context continuity. Threads stay in Perplexity; only what you archive comes across.
- Shared Space collaboration. Gemini's sharing model differs.
- Ongoing sync. A snapshot today doesn't propagate later Space changes unless you re-upload.
The better way: one memory layer, every AI
The structural cost is the per-tool walls. The fix is to hold memory outside any single AI.
MemoryLake holds your documents and rules once and exposes them through MCP. Gemini integrations can read the same MemoryLake project through a Workspace add-on or external integration calling its REST endpoint.
- One source of truth. Update once; both sides see the change.
- Standard file formats. PDFs, Word, Excel, PowerPoint, Markdown, and images live in MemoryLake's Document Drive as-is.
- Drop-in for the next AI. Add Claude or ChatGPT with a config change.
Connect MemoryLake in 3 steps
Step 1: Create a project and load your context
Sign in to MemoryLake, open Project Management, and click Create Project. Name it "Perplexity ↔ Gemini shared context." Drag your downloaded Space files (PDF, Word, Excel, PowerPoint, Markdown, or images) into the Document Drive under My Space, then open the Documents Tab and click Add Documents. Paste each Space's Instructions and any archived Thread highlights into the Memories Tab via Add Memory.

Step 2: Generate an MCP Server endpoint
Open the MCP Servers Tab inside the project, click Add MCP Server, describe it (e.g., "Perplexity + Gemini bridge"), and click Generate. MemoryLake returns a Key ID, a Secret, and an Endpoint URL. Copy the Secret immediately — it is shown only once.

Step 3: Point both tools at the endpoint
For Gemini, run a Workspace add-on or external integration that calls the REST endpoint with the Bearer token and injects the returned context into a Gem's instructions or your prompt. For Perplexity, build a small integration that calls the same REST endpoint with the Bearer token and injects context into a Space's Instructions or thread opener.

Native migration vs MemoryLake
| Dimension | Native Perplexity → Gemini | MemoryLake bridge |
|---|---|---|
| Steps required | 7–10 manual | 3 one-time |
| Estimated time | 20–40 min per Space | ~5 min setup |
| Preserves Space → Gem boundary | Yes (manual) | Yes (one Project) |
| Live document sync | Drive folder (yes) | Files in MemoryLake, integrations fetch live |
| Syncs ongoing changes | No (Perplexity side) | Yes (within MemoryLake) |
| Works with a third AI later | No (rebuild) | Yes (add MCP) |
