ChatCapsule
Turn bloated AI chats into memory chips for Obsidian
Stop browser lag from long AI chats. ChatCapsule extracts high-density memory chips from Claude & ChatGPT, syncing directly to your local Obsidian vault via W3C File System API. 100% private, zero token loss, and a $29 one-time purchase with no subscriptions.
Hey Product Hunt! 👋 I'm Joanne, the maker behind ChatCapsule.
Like many heavy AI users, my breaking point was losing a critical 47-turn brainstorming session on Claude when the tab froze and crashed. Browser memory bloat, lost project context, and the repetitive pain of "re-explaining everything to the AI" in a new chat was killing my daily workflow.
I built ChatCapsule to solve this permanently. Instead of letting long conversations degrade your browser, ChatCapsule distills the entire context into a high-density "Memory Chip." You can inject it into a fresh chat window to pick up instantly with zero latency—and seamlessly sync clean Markdown notes into your local Obsidian vault. Zero cloud servers, 100% local storage.
Why $29 lifetime? Like many of you, I have extreme subscription fatigue. Why pay $10/month forever ($600 over 5 years) just to manage your own notes? ChatCapsule is a $29 one-time purchase that pays for itself in less than 3 months.
I’d love to hear your thoughts, feedback, or any edge cases you run into! I'll be hanging out here all day to answer every single question. 🚀
Hi Product Hunt! 👋 I'm Joanne, the creator behind ChatCapsule.
As someone running long-term technical projects across Claude, Gemini, and ChatGPT, my chat threads easily hit 1,000+ messages. Over time, I ran into two deal-breaking problems:
1. The virtual DOM wall & browser freezing: Deep chats make browsers crawl. Copying manually or using naive scrapers almost always drops unmounted DOM nodes, leaving truncated code and missing context.
2. The "New Chat Amnesia": Starting a new chat meant losing all project boundaries, non-negotiable architectural decisions, and refined personas. Generic chat summaries just water down these hard-earned rules into useless bullet points.
I built ChatCapsule to introduce a 100% local, friction-free "Context Handover" workflow:
- 🪜 Ladder-Scroll DOM Scraping: Automatically traverses massive threads to capture full conversation fidelity directly to your local Obsidian vault without dropped tokens.
- 🧹 Clean Text Mode: Folds giant code blocks (>15 lines) with one toggle, so your exported vault notes stay clean and readable—or leave it unchecked for raw code preservation.
- 🧬 Self-Extracting Role Capsules: Trigger "Extract Persona" in your current thread to let the AI formalize its own identity, strict constraints, and finalized decisions. Hitting "Append Sync" locks this directly into the top of your local `.md` file as a permanent Memory Chip.
- ⚡ One-Click Hot-Swapping into Fresh Chats: Open any fresh chat tab (Claude, Gemini, or ChatGPT), import the capsule `.md`, and hit "Inject Memory". The new AI instance instantly inherits the exact identity, context boundaries, and decisions to pick up right where the previous thread left off.
Everything runs strictly on your machine using the Chrome File System Access API—zero servers, zero cloud middleman, no API keys required.
Try the free version directly on the Chrome Web Store (includes 2 free role capsules):
I’d love to hear feedback from fellow Obsidian builders and heavy AI prompters! 🚀
