An architecture designed for notes

Still managing notes with coding tools?

Claude Code, Codex, OpenClaw, Hermes. They are built for software engineering, not for notes. Expensive, and not well managed: pay for costly model quotas, just to find a few notes?

Born for notes, not for engineering

  • Completion-first agent loop, repeated calls blocked
  • Library Graph local retrieval, no embedding API or vector DB
  • DeepSeek-compatible and cache-friendly, cost visible in chat
  • Replaceable models, locked to no expensive vendor
TierNote AI workspace
The more you use, the more you save

Every token earns its keep

Deeply optimized for DeepSeek and other affordable models. Cost engineering, not a crippled budget mode.

AI chat with token cost

Cheap models, done right

  • Cache hit rate visible in the chat
  • Memory routing, not whole-library dumps
  • Token, calls and cost shown per request
Your context stays yours

Give AI the context that actually matters

Keep goals, experience, lessons, and key records local. You decide what AI can retrieve.

Useful memory, under your control

  • Enable or disable each personal context independently
  • Connect long-term goals with the work in front of you
  • Local files remain readable, editable, and portable
TierNote personal contexts
One click, short video to note

Any video URL becomes a note

From "watched and forgotten" to searchable, quotable, reviewable.

Media transcription dialog

Short video, three steps to a note

  • Paste a video link: TikTok, YouTube, X
  • Auto-transcribe: video to audio, audio to text, API or local engine
  • Agent writes the note: spoken content becomes structured Markdown
Capture from your phone

Send a link. Get a finished note

Connect Weixin or Telegram, send a video or webpage privately, and let TierNote organize it on your computer.

Your desktop does the work

  • Weixin for China, Telegram for everywhere else
  • Results are saved directly into your local note library
  • Private pairing and restricted channel permissions
