Perplexity AI started as a real-time answer engine, but with Spaces it becomes something bigger: a place to organize, share, and grow research over time.
Instead of random, one-off chats, Spaces give you persistent workspaces where you and (optionally) your team can:
Group related threads by topic
Upload files and let Perplexity reason over them
Add custom instructions for that Space
Collaborate, comment, and share results with others
Think of a Space as a mix between a project folder, a shared notebook, and a smart research assistant—all in one.
Perplexity’s help center defines Spaces as “dedicated workspaces that allow individual users and teams to organize, collaborate, and manage research more effectively.”
Inside each Space you can:
Keep multiple threads (conversations) about that topic
Attach files and links for Perplexity to analyze
Use custom instructions so the AI answers in a specific tone or format
Share the Space with classmates, teammates, or clients for collaborative research
So instead of one messy global chat history, you get topic-based hubs like:
“Perplexity vs other AI tools”
“Tech Stocks & Market Insights”
“Japan Trip Planning 2026”
“Client X – SEO Strategy Research”
Each hub keeps its own context, files, and instructions.
Each Space is focused on a single topic or project:
All related questions, follow-ups, and Deep Research runs live inside that Space
You can revisit any thread later to continue from where you stopped
Spaces act as knowledge archives, not disposable chats
This is especially helpful for long-running projects (courses, client accounts, content series, stock research, etc.).
Spaces integrate with Perplexity’s Internal Knowledge Search:
You can upload documents (PDFs, slides, notes) directly into a Space
Perplexity then searches both your files and the live web when answering
Answers can cite your internal docs and external sources side by side
Community and official guides note that even free accounts can upload a small number of files per Space (for example, 5 docs), while Pro and Enterprise raise these limits significantly for serious research work.
This turns a Space into your own mini knowledge base.
Spaces support Space-level custom instructions, so you can tell Perplexity how to behave only inside that Space:
Examples:
“Always answer as an SEO expert and use UK English.”
“Summarize in bullet points under 300 words.”
“Write explanations at a high-school reading level and include definitions of jargon.”
Every new thread created in that Space automatically follows those rules—no need to paste the same mega-prompt each time.
Perplexity Spaces are built for collaboration, not just solo work:
Share Spaces with classmates, colleagues, or clients
Invite people to view, comment, or contribute new threads
Use Space-level access controls (Pro/Enterprise) to manage who can see or edit what
Guides mention:
Pro users can typically share Spaces with a small group of collaborators
Enterprise plans can support larger teams and more granular controls (space-level permissions, retention policies, etc.)
Public link sharing is also available, so you can publish a Space as a resource for others to read.
Because Spaces group threads and files, they’re ideal for long-form projects:
Keep separate threads for different sections of a report or article
Store research, outlines, and drafts in one Space
Use custom instructions to enforce consistent tone/format across all outputs
Tutorials show people using Spaces for:
Book notes and chapter-by-chapter summaries
40+-point stock research checklists with separate prompts per criterion
Multi-module online courses with one Space per subject
Open perplexity.ai and sign in.
Click Spaces in the sidebar.
Hit “New Space” (or “+” button).
Give it a name and optional description, like “Perplexity AI Review Research”.
Inside your new Space:
Upload PDFs, slides, notes, or CSVs that are relevant to this topic.
Set Custom Instructions for that Space (tone, audience, output style).
Example instructions:
“You are a research assistant helping write long-form blog posts. Always show sources, avoid plagiarism, and suggest headings and tables when useful.”
Create your first thread with a clear, focused question:
“Give me a high-level overview of Perplexity Spaces and how they compare to Notion & Obsidian.”
“Summarize each of my uploaded PDFs into 300-word notes with key quotes.”
Each thread stays inside the Space, so you can come back later and add follow-up questions without losing context.
For group work:
Share the Space via invite or a shareable link.
Decide whether collaborators can edit, comment, or just view (depending on your plan).
This is especially useful for team projects, client research, or study groups.
Over time, your Space becomes:
A living knowledge base on that topic
A place to re-run Deep Research, update comparisons, and keep things current
A reusable asset you can share with new teammates or classmates
Perplexity’s own blog highlights Spaces as ideal for students:
One Space per course or exam (e.g., “Physics 101” or “World History Final”)
Upload lecture notes, PDFs, and slides
Use AI to:
Generate study guides & flashcards
Create practice questions from your notes
Simplify hard concepts in your own words
Study groups can share a Space and build a shared knowledge hub instead of scattered chats.
If you run a content site or YouTube channel, you can:
Create one Space per topic cluster (e.g., “Perplexity content series”, “AI video tools”, “EV reviews”).
Store research, outlines, and drafts in that Space.
Use Space instructions to keep tone and structure consistent across all articles.
Because all threads and files live together, it’s easier to avoid duplication and keep your info up-to-date.
For teams, Spaces become project or client hubs:
Sales teams – store client decks, proposals, and notes; use AI to draft emails and RFP responses based on shared docs.
Product teams – centralize research on competitors, user interviews, and feature ideas.
Support teams – turn internal manuals and FAQs into an AI-queryable knowledge base; draft help-center articles.
Enterprise features like access controls, retention policies, and larger file limits make Spaces suitable for company-level deployments.
On Reddit and blogs, many users talk about using Spaces for stock research:
Upload company reports, investor presentations, and 10-Ks.
Create separate threads for each part of a research checklist (moat, growth, risks, valuation).
Let Perplexity summarize, compare competitors, and turn findings into written memos.
Because the Space keeps all that information together, you can re-open it when new earnings come out and add updated Deep Research.
Exact quotas change over time, but docs and community posts show a general pattern:
Free plan
Access to Spaces
Basic file uploads with modest limits (e.g., a handful of documents per Space)
Great for individuals, students, and light research
Perplexity Pro
Higher limits on Spaces, file uploads, and collaborators
Better suited to active researchers, content creators, and small teams
Enterprise
Org-wide Spaces with advanced access control, SSO/SCIM, and custom retention
Unlimited or high collaborator counts
Designed for companies integrating Perplexity into daily workflows
If you frequently hit upload or collaboration limits, that’s your sign to move from Free → Pro.
To get more out of Spaces, combine good structure + good prompts:
Create one Space per project, not “Everything AI”.
Use one thread per question or sub-task (pricing research, competitors, outline, FAQ, etc.).
Name threads clearly:
“01 – High-level overview”
“02 – Competitor comparison table”
“03 – FAQ draft for Perplexity vs ChatGPT”
Research summary:
“Using all files in this Space plus the live web, create a 1,000-word overview of [TOPIC] with headings, bullet points, and citations.”
Content writing:
“Act as an SEO writer. Based on our research threads in this Space, draft a blog post on ‘Perplexity AI Spaces’ with an intro, 5–6 H2s, FAQ section, and internal links suggestions.”
Study mode:
“From my uploaded lecture notes, generate 20 flashcards (Q on one side, A on the other) and highlight any definitions I should memorize.”
Team briefing:
“Summarize everything we’ve researched in this Space into a 2-page internal brief for executives. Include key stats, risks, and a short recommendation.”
Even though Spaces are powerful, keep a few things in mind:
AI summaries can still miss nuance or misinterpret sources—check important claims against the original files or links.
File and collaborator limits depend on your plan; very large teams or data sets may need Enterprise.
For sensitive topics (legal, medical, financial), treat Perplexity’s outputs as draft research, not final professional advice.
Use Perplexity AI Spaces whenever you need to:
Work on a topic over days, weeks, or months, not just one quick answer
Combine your own files + web research
Collaborate with classmates, colleagues, or clients in a shared AI workspace
Turn Perplexity from a simple Q&A tool into a persistent knowledge hub
If you’re already relying on Perplexity for answers, Spaces is the feature that turns all that one-off research into organized, reusable knowledge—so every new project starts a little smarter than the last.
