The real catalog of tools for AI agents

Cross-session, cross-device memory for your agent: remember and recall notes. No key to start.

Statements, invoices, tables, ledgers — every result carries its own arithmetic proof.

Translation that never breaks structure: .srt timings, i18n key trees, PDF layout.

Chinese almanac: lunar calendar, BaZi 八字, daily 宜忌, lucky-day picker, public holidays.

Messy spreadsheets in, clean checkable tables out. Every result carries its arithmetic proof.

Markdown in, any format out. PDFs merged, split, watermarked. Runs on our own doc engines.

Diagrams, badges, charts and QR codes as plain image URLs you can paste into Markdown.

China facts a server outside China cannot get: real mainland reachability, 调休 holidays, ID/phone val

JSON/YAML, regex, diff, JWT, SQL dialects — the keyless millisecond ops an agent needs mid-task.

Recurring agent jobs that run on our servers and ping you only when the result changed.

Tables and ledgers checked by arithmetic, not by a model. 24 tools. MCP 2026-07-28 ready.

Live data: weather, air quality, FX, CN/HK/US stocks, IP geo, domain, SSL, China reachability.

Deploy a live web app from one sentence. build_app + poll to a public HTTPS URL you own.

Encrypted long-term memory shared across your AI assistants (Claude, ChatGPT, Perplexity).

Persistent semantic memory storage, associative recall, and recent memory index by namespace.

Persistent memory for AI agents. Semantic search, memory graph, W3C DID identity.

Persistent business-intelligence memory for AI agents.

An MCP memory server. One memory your agents share — across models, devices and apps.

Cross-session memory for AI agents with a Source Receipt for every memory, over MCP.

Private cross-media memory for AI assistants: recommendations, progress and controlled actions.
