CursorMemory — AI Session Context Dashboard for Cursor Users
Cursor AI doesn't persist memory across conversations by default, leaving developers confused about what context is lost between sessions. CursorMemory gives you a visual dashboard to save, tag, and inject project context into every new Cursor conversation — so you never re-explain your codebase again.

— sourced from real search demand
Developers are actively searching to understand whether Cursor AI retains memory between separate conversations, indicating real frustration with context loss across coding sessions.
What is it?
Developers using Cursor AI constantly hit the same wall: each new conversation starts blank, with no memory of previous decisions, architecture choices, or debugging history. CursorMemory solves this by letting users save named 'memory snapshots' — structured context blocks about their project — that can be copied into any new Cursor session with one click. Users paste a generated system prompt block into Cursor's rules or chat, instantly giving the AI full project context. The app also shows a timeline of what context was active during past sessions, answering the exact question: 'does Cursor track memory across conversations?' (short answer: no — and here's how to fix it). Monetized as a $9/month SaaS with a free tier capped at 3 memory snapshots.
Why now?
Cursor crossed 500k active users in early 2025 and still has no native cross-session memory. Searches for 'cursor ai memory' are rising monthly. The pain is real, documented, and unsolved — and no purpose-built tool exists yet.
- ▸Memory Snapshot Editor — structured form to capture project name, tech stack, architecture decisions, known issues, and coding conventions, saved to Supabase and editable anytime
- ▸One-Click Context Generator — instantly compiles a snapshot into a formatted system prompt block optimized for Cursor's chat or .cursorrules file, with a copy-to-clipboard button
- ▸Session Timeline — log entries showing which memory snapshot was active when, so users can see exactly what context Cursor had access to in past sessions
- ▸Snapshot Switcher — quickly switch between project memory snapshots when jumping between codebases, with a browser extension bookmarklet shortcut
Target Audience
Cursor AI power users — solo developers, indie hackers, and freelancers who use Cursor daily and manage 2+ projects simultaneously, estimated 500k+ active Cursor users globally.
Example Use Case
Priya works on 4 client projects in Cursor. She saves a memory snapshot per project — stack, conventions, known bugs — and pastes the generated block into each new Cursor chat in 2 seconds instead of typing 3 paragraphs of context every time.
User Stories
- ▸As a freelance developer juggling 4 client projects in Cursor, I want to save and instantly reload each project's context so that I stop wasting 10 minutes re-explaining the codebase at the start of every session.
- ▸As a Cursor power user curious about AI memory, I want to see a clear explanation of whether Cursor tracks memory across conversations and a practical workaround so that I understand what context the AI actually has.
- ▸As a Pro subscriber with 10+ projects, I want to switch between project memory snapshots in one click and see a log of when each was last used so that I can manage my AI context the same way I manage git branches.
Done When
- ✓Snapshot creation: done when a user can fill in the structured form, save a snapshot, and see it listed in their dashboard within 1 second.
- ✓Context block generation: done when clicking 'Copy to Cursor' compiles the snapshot into a formatted prompt block, copies it to clipboard, and logs the session event — all without a page reload.
- ✓Auth: done when Google OAuth redirects back to the dashboard showing the user's display name and their snapshots are scoped to their account only via Supabase RLS.
- ✓Payment: done when clicking 'Upgrade to Pro' launches Stripe Checkout, payment succeeds, webhook fires, and the user's dashboard immediately unlocks unlimited snapshots without a manual refresh.
Is it worth building?
$9/month x 120 users = $1,080 MRR by month 3. $19/month Pro tier x 30 power users adds $570. Total: ~$1,650 MRR at month 3.
Unit Economics
CAC: ~$2 via organic Reddit/X posts (time cost only). LTV: $108 (12 months at $9/month, 70% annual retention). Payback period: immediate (no paid ads). Gross margin: ~97% (near-zero infra cost at early scale).
Business Model
Freemium SaaS subscription
Monetization Path
Free tier: 3 memory snapshots, no history. Pro $9/month: unlimited snapshots, session timeline, export. Team $29/month: shared team memory library. Free-to-paid conversion target: 10%.
Revenue Timeline
First dollar: day 8 (beta user upgrades). $500 MRR: month 2. $1,500 MRR: month 3. $5k MRR: month 10.
Estimated Monthly Cost
Supabase Free tier (first 500MB): $0. Vercel hobby: $0. Resend free tier: $0. Stripe fees: ~3% of revenue. Total fixed cost at launch: $0. Scales to ~$25/month at 500 users.
Profit Potential
Full-time viable at $5k MRR (month 10-12). Side-income viable at $1k MRR (month 3-4).
Scalability
Medium-High — team shared libraries, Cursor extension in V2, API for power users to sync context programmatically.
Success Metrics
Week 1: 200 signups from Reddit/X launch post. Month 1: 30 paying users. Month 2: 85% monthly retention. Month 3: 120 paying users.
Launch & Validation Plan
Post in r/cursor and r/ChatGPTCoding asking 'how do you handle memory across Cursor sessions?' — gauge pain. DM 15 active Cursor users on X offering free beta access. Build landing page first, collect 50 emails before writing app code.
Customer Acquisition Strategy
Day 1: Post in r/cursor, r/SideProject, r/ChatGPTCoding with screenshot of the context block generator. Day 3: X thread explaining why Cursor has no memory and how to fix it manually — CursorMemory as the solution. Week 2: ProductHunt launch. Month 2: SEO blog post targeting 'cursor ai memory' and 'cursor ai context between sessions'.
What's the competition?
Competition Level
Low
Similar Products
Notion (generic notes, no Cursor-specific formatting), .cursorrules files (manual, no UI, no history) — neither tracks session context or generates structured prompt blocks.
Competitive Advantage
Only tool purpose-built for Cursor's lack of cross-session memory. Competitors like Notion or plain text files require manual formatting. CursorMemory auto-formats context in Cursor-optimized prompt structure and tracks session history.
Regulatory Risks
Low. No code is stored, only developer-written text descriptions. GDPR compliance covered by Supabase's EU data residency option.
What's the roadmap?
Feature Roadmap
V1 (launch, day 10): snapshot editor, context block generator, session timeline, Stripe Pro upgrade. V2 (month 2): AI-assisted snapshot generation from pasted README or package.json, snapshot sharing via public link. V3 (month 4): Chrome extension for one-click inject into Cursor web, team shared snapshot library.
Milestone Plan
Phase 1 (Days 1-5): Supabase schema, auth, snapshot CRUD API, basic dashboard UI — done when a logged-in user can create and read snapshots. Phase 2 (Days 6-10): context block generator, copy + session log, Stripe upgrade flow, landing page — done when a stranger can sign up, create a snapshot, copy context, and pay for Pro. Phase 3 (Month 2): AI snapshot generation from README input, ProductHunt launch, 50 paying users milestone.
How do you build it?
Tech Stack
Next.js 14, Supabase (auth + DB), Tailwind CSS, shadcn/ui, Stripe — build the whole thing with Cursor
Suggested Frameworks
Supabase Auth, shadcn/ui component library, Stripe Checkout, Resend for email
Time to Ship
10 days
Required Skills
Next.js basics, Supabase CRUD, Stripe Checkout, copy-to-clipboard UI patterns.
Resources
Supabase quickstart docs, Stripe Checkout guide, shadcn/ui component docs, Cursor .cursorrules documentation.
MVP Scope
app/page.tsx (landing + explainer), app/dashboard/page.tsx (snapshot list), app/dashboard/[id]/page.tsx (snapshot editor), app/api/snapshots/route.ts (CRUD), lib/db.ts (Supabase schema), components/SnapshotCard.tsx, components/ContextBlock.tsx (generated output)
Core User Journey
Sign up with Google -> create first memory snapshot (guided form) -> copy generated context block -> paste into Cursor chat -> see session logged in timeline -> hit free tier limit -> upgrade to Pro.
Architecture Pattern
User creates snapshot -> saved to Supabase -> context block generated client-side -> copied to clipboard -> user pastes into Cursor. Session log written on each copy event.
Data Model
User has many Snapshots. Snapshot has many SessionLogs. Snapshot fields: id, user_id, project_name, tech_stack, architecture_notes, conventions, known_issues, created_at, updated_at. SessionLog fields: id, snapshot_id, copied_at, cursor_context_block_hash.
Integration Points
Supabase Auth (Google OAuth), Supabase Postgres (snapshot storage), Stripe Checkout (Pro upgrade), Resend (welcome + upgrade emails), Vercel (hosting + edge functions).
V1 Scope Boundaries
V1 excludes: browser extension, Cursor plugin, team shared libraries, AI-assisted snapshot generation, version history of snapshots, mobile app.
Success Definition
A paying stranger creates a memory snapshot, copies the context block, uses it in Cursor, and returns the next day to update the snapshot — without founder help.
Challenges
Distribution is the core challenge — Cursor users are technical but scattered across Reddit, X, and Discord. Must reach them before Cursor ships native memory (which would kill the product).
Avoid These Pitfalls
Don't wait for Cursor to ship native memory — build and launch in 10 days before the market closes. Cursor has signaled memory is on the roadmap. Don't over-engineer the context block format — ship one opinionated template first and let user feedback drive iteration. Avoid building a flexible template engine in V1.
Security Requirements
Supabase RLS policies ensuring users can only read/write their own snapshots and session logs. Google OAuth only (no password auth in V1). Rate limiting 60 API requests/minute per user via Supabase edge functions. No raw code stored — text descriptions only.
Infrastructure Plan
Vercel for Next.js hosting (edge runtime for API routes), Supabase for Postgres DB + Auth + storage, GitHub Actions for CI (lint + type-check on PR), Sentry for error tracking, Vercel Analytics for page-level metrics.
Performance Targets
Dashboard load under 1.5s. Context block generation under 100ms (client-side string operation). API snapshot save under 300ms. Target: 500 DAU, 5k requests/day at month 3 — well within Supabase free tier limits.

First Run Experience
On first login, a demo snapshot called 'Example: Next.js SaaS Starter' is pre-loaded with sample data. User can immediately click 'Copy to Cursor' to see the generated context block — then edit the demo or create their first real project snapshot. No blank state, no setup friction.
How to build it, step by step
1. Define Supabase schema (users, snapshots, session_logs tables with RLS). 2. Set up Supabase project and enable Google OAuth. 3. Scaffold Next.js 14 app with shadcn/ui and Tailwind. 4. Build snapshot CRUD API routes in app/api/snapshots. 5. Build snapshot editor UI with structured form fields. 6. Build context block generator function that compiles snapshot into formatted prompt string. 7. Add copy-to-clipboard with session log write on copy. 8. Add Stripe Checkout for Pro upgrade with webhook to update user tier. 9. Add Resend welcome email on signup. 10. Deploy to Vercel, verify full user journey end-to-end with a real Cursor session.
