SpawnGraph turns any PDF, URL, YouTube video, Word doc, PowerPoint, EPUB, or 90+ other file formats into an editable hierarchical mind map in seconds. All natural-language processing runs entirely in your browser โ no data uploads, no AI API costs, no signup required. Real-time multi-user collaboration is included on every plan including the free tier. Built for students, researchers, consultants, and content creators who need to synthesize source material fast.
Key differentiators: โข Browser-native NLP โ verifiable in DevTools, your content never leaves your device during generation โข 93+ file formats supported (PDFs, Word, PowerPoint, EPUB, YouTube transcripts, images via OCR, audio via Whisper WASM) โข Real-time multi-user collaboration on every plan including free โข No per-seat pricing โข Free tier is the product, not a trial
Ayoa takes online collaborative whiteboards to new heights. By seamlessly blending idea generation, task management and team collaboration features, Ayoa goes beyond convention and provides a platform for teams to work together and cultivate knowledge that can be used to drive success.
The Ayoa way of working gives users the speed and fluidity to capture and grow great ideas, instantly action them and develop better working practices. Our flexible features allow teams of any size to do it all, whether itโs planning a project, conducting effective meetings, or anything in between.
SpawnGraph AyoaSpawnGraph's answer
SpawnGraph is the only mind mapping tool that combines three things in one product: (1) browser-native natural-language processing โ every PDF, document, and transcript is parsed entirely client-side, so your content never reaches our servers and you can verify it in DevTools โ 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 โ none of it leaves your browser during generation. This isn't a marketing claim; open DevTools โ 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 โ 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 โ 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 2024โ2025 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 โ 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 โ 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.

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 โ single VPS + Cloudflare free tier + small Postgres instance.

Ayoa is like a combination of Slack, Miro and Trello in a single app. I love to work visually and with the mind mapping, combined with very visual task management (especially the canvas view), it is a nice way to work for me and the team. I can't wait for the new whiteboard view that Ayoa is releasing soon.....
I'm using Ayoa at work. After using Ayoa, it became possible to share the work of team members in real time. As a result, unnecessary or repetitive communication has been reduced. And Ayoa includes most of the functions needed for collaboration, such as Project Management, Gantt chart, Calendar, Mindmap, Brainstorm and Video Meeting. You can do most of the work within Ayoa without the need for multiple applications. Above all, Ayoa is able to share parts with the entire, playing a guiding role in achieving the team's goals.
AYOA is the evolution of iMindMap and now it is so much more. I am amazed by what this app can do! We can still do mindmaps, and we can have task management and project management! We can collaborate with colleagues and with our team members! And it all is perfectly integrated! And I know what's coming: videoconference and whiteboard! Then AYOA will be not only super but unbeatable! I manage many aspects of my business on AYOA and I recommend you give it a try!
