The system

One place for the different kinds of thinking the FRCS demands.

thinKbox FRCS is not a generic notebook with an orthopaedic label. Its workflows are organised around reading, capturing, connecting, recalling, practising and rehearsing FRCS material.

01 · Read

The FRCS library, without the friction.

Start with the protected offline corpus. Search across it quickly, move through connected notes, and use backlinks to see where a concept is referenced elsewhere.

02 · Capture

Capture first. Organise when it matters.

Create permanent notes when the thought is formed. Use Fleeting notes when it is not. Add media or a drawing, then develop the note later without losing the raw idea.

03 · Recall

Notes that come back when they should.

thinKbox extracts flashcards from Q/A and cloze syntax, while Spaced Inbox schedules whole notes. Today shows what is due, what is recent and what still needs processing.

04 · Practice

Practise, inspect the miss, then clear it.

The SBA workflow is more than sequential questions: configure a session, filter by module and difficulty, choose timing, flag uncertainty, inspect progress and work a review queue of flagged or incorrect questions.

Turn an illustration into a five-minute answer.

Viva stations present one illustration at a time with an editable description field below it, so you can build and refine a talkable answer instead of passively recognising an image.

See the neighbourhood, not just the note.

Brain Map visualises permanent notes and their relationships. Start from the current neighbourhood, zoom out to all notes, or filter by category to inspect how ideas cluster.

Ask the note. Keep the note on the device.

Import a quantized GGUF model and run llama.cpp inside thinKbox on iPhone or iPad. AI starts from the current note, and nothing is inserted or applied until you explicitly approve it.

Practice engine

A question bank that remembers what you got wrong.

Build a focused SBA session instead of merely scrolling a bank. Answers, flags and progress stay on the device, and missed or flagged questions feed a review-and-approve queue.

KneeDifficulty 4★ Fellowship topic90 sec

Which principle best explains the change in tibiofemoral contact mechanics after meniscal loss?

A. Reduced joint reaction force

B. Reduced contact area with increased contact stress

C. Increased congruity and lower peak pressure

D. Isolated increase in shear without compression change

Review the reasoning. The result panel keeps the answer and explanation adjacent to the question, then lets uncertain items remain in the review queue.

Your notes

The library is the starting point. Your connections are the system.

Permanent notes participate in links, backlinks, flashcards, Brain Map, categories and spaced review. Fleeting notes deliberately do not—until you develop them.

Linked-note navigation

Move through a sequence of recently opened notes as stacked spines, while the current note remains full-size. This preserves context without turning navigation into a separate screen.

History before regret.

Editing and AI-approved changes continue through note history / backup, so you can inspect previous states rather than treating save as irreversible.

Fleeting stays deliberately lightweight.

Capture a rough idea fast. Until it becomes permanent, it stays out of Brain Map, backlinks, flashcards, Spaced Inbox, tags/categories and default search.

On-device intelligence

Local AI, with a hard boundary between suggestion and edit.

thinKbox runs llama.cpp inside the iOS app. Import a quantized GGUF model from Files; the current note is the default scope, and AI output remains a suggestion until you explicitly choose Insert or Apply.

Runtime: llama.cpp inside thinKbox on iPhone or iPad.
Model: User-imported quantized .gguf model; 1B–3B Q4 is the practical starting point described in the app.
Default scope: Current note only. Link suggestions additionally receive note titles / aliases, not other note bodies.
Write policy: AI never replaces a note automatically. Insert / Apply requires explicit user action.
Tools: Ask, Summarize, Explain, Generate Q&A, Generate Clozes, Suggest Links, Suggest Tags.

> Explain the key management decision in this note.

The note frames the decision around stability, remaining growth, deformity and the risk of progression. The note does not contain enough information to extend beyond those stated criteria.
