Introducing SpawnGraph: Real-Time Collaborative Mind Mapping Board Free Tool
How often each product is chosen within a category, 0–100% relative to the other.


As answered by people managing Zistemo and SpawnGraph.
SpawnGraph's answer:
SpawnGraph is the only mind mapping tool that combines three things in one product: (1) browser-native natural-language processing — every PDF, document, and transcript is parsed entirely client-side, so your content never reaches our servers and you can verify it in DevTools → Network; (2) automatic mind map generation from 93+ source file formats including PDFs, Word, PowerPoint, EPUBs, YouTube transcripts (auto-fetched), audio recordings (Whisper WASM), and images (Tesseract OCR); and (3) real-time multi-user collaboration with named cursors on every plan including the free tier, with no per-seat pricing. Every other tool in the category sends your content to a cloud AI service, charges per generation, or locks collaboration behind a paid tier.
SpawnGraph's answer:
Three reasons:
Speed-to-first-map. Drop a 30-page research paper and SpawnGraph produces a hierarchical mind map in under 2 seconds. Tools like MindMeister, Miro, and Whimsical require you to type every node yourself. AI tools like Mapify or MyMap upload your document, charge per generation, and wait several seconds for a model round-trip.
Genuine privacy. Confidential pre-prints, interview transcripts, legal contracts, embargoed materials — none of it leaves your browser during generation. This isn't a marketing claim; open DevTools → Network and watch zero outbound requests during a generation. Critical for researchers, lawyers, and anyone working with sensitive content.
Free tier is the product, not a trial. Miro caps you at 3 editable boards. MindMeister at 3 maps. Heptabase has no free tier at all — just a 7-day trial. SpawnGraph's free tier covers 2 saved mindmaps, 8 export formats including watermarked PNG, real-time collaboration with up to 5 editors per board, and unlimited generation from any of 93+ file formats. Solo Pro at $5/month annual unlocks unlimited boards and the full export set — but the free tier is genuinely usable forever.
SpawnGraph's answer:
SpawnGraph's primary users are knowledge workers who deal with a lot of source material and need to extract structure from it quickly:
Secondary audience: PKM enthusiasts (Obsidian, Heptabase, Logseq users) looking for a visual synthesis tool that complements their long-term knowledge management vault.
SpawnGraph's answer:
I built SpawnGraph because every "AI mind map" tool I tried in 2024–2025 had three problems: they required signup, they uploaded my PDFs to their servers, and they charged per generation (sometimes hidden as "credits"). I wanted to map research papers, technical docs, and YouTube talks without any of those constraints.
The technical insight was that modern browsers can do most of the heavy lifting client-side: pdf.js for PDF text extraction, Intl.Segmenter for tokenization (built into V8), heading-hierarchy reconstruction in plain JavaScript, Whisper.cpp WASM for audio transcription, and Tesseract.js for image OCR. The "AI" part of AI mind maps was largely unnecessary — most real-world documents already have implicit structure (headings, paragraphs, lists) that can be extracted deterministically.
Real-time collaboration was added next because mind mapping is genuinely better as a multi-player activity. We used Yjs CRDTs over a custom binary WebSocket protocol — the same underlying tech as Linear, Figma's multiplayer layer, and AFFiNE.
The product is solo-built and bootstrapped. We're currently pivoting toward a local-first desktop model (Tauri 2.x) for power users who want the same workflow without any browser dependency, modeled on Obsidian's approach.
SpawnGraph's answer:
Frontend (browser): - React 19 + Vite + TypeScript - @xyflow/react for the canvas - Yjs + y-indexeddb + y-protocols for real-time CRDT collaboration - Zustand for client state - Tailwind CSS for styling - pdf.js for PDF text extraction - Intl.Segmenter for tokenization - Whisper.cpp WASM for audio transcription - Tesseract.js for image OCR - @xenova/transformers for browser-side ML utilities - pdf-lib + pptxgenjs + jszip for client-side export to PDF/PPTX/zip - React Router v6 + SSR prerender for marketing pages
Backend: - Hono framework on Node.js (single VPS) - Postgres for primary storage - Lucia Auth for session management - Yjs sync server (WebSocket binary protocol) - Dodo Payments for billing (not Stripe) - Cloudflare Pages for static hosting + edge caching - Cloudflare DNS + Cloudflare Insights for analytics
Infra cost is ~$30/month at current traffic — single VPS + Cloudflare free tier + small Postgres instance.
