Claude 4.5 raises the bar on agentic coding
Minimalist card layouts — mood board
tanstack/react-virtual — v3 release notes
A power-user bookmark manager,
disguised as a timeline.
AI categorisation
Every link is auto-tagged by Claude Sonnet 4.5 — category, tags, and clean metadata.
Hybrid semantic search
Ask in natural language. We blend OpenAI embeddings with keyword scoring for razor-sharp recall.
Bulk ingest queue
Paste 500 URLs — a FIFO worker chews through them with retries and a dead-letter queue.
Virtualised timeline
Renders 550+ cards without breaking a sweat. Chronological or grouped by month.
Command palette
Cmd+Shift+K opens a fuzzy palette for every action — with recents pinned on top.
Browser extension
One click to send the current tab (or a text selection) to your timeline.
Multi-level undo
Every bulk delete, retag or recategorise is stashed on a Cmd+Z stack up to 20 deep.
Markdown & JSON export
Own your data. Export the current view or the whole archive in one click.
Yours only
Google login, session cookies, per-user isolation. No trackers, no re-selling.
Paste. Wait 3 seconds.
Timeline appears.
Threadline ingests URLs in the background so the UI never blocks. The queue panel surfaces progress, retries handle transient failures, and the timeline lights up as cards land.
Free forever.

FAQ
Is my data private?+
Yes. Each user's links, tags and notes are strictly isolated. We don't share, resell, or train models on your data.
Can I cancel Pro?+
Anytime, from the Stripe customer portal. Your links stay accessible on the free tier (up to 50).
Which browsers does the extension support?+
Chrome, Edge, and Brave (MV3 manifest). Firefox port is on the roadmap.
Do you use OpenAI?+
Only for semantic search embeddings (title + description). Categorisation runs on Anthropic Claude via the Emergent LLM proxy.
