Get a free Gemini key
Sensei runs on Google's Gemini API. It's genuinely free — no credit card, no trial that expires — you just need a key tied to your Google account.
What you'll see over there
1
If asked, sign in with your Google account
2
Tap Create API key
3
Under "Name your key," type Flowverse BJJ — so you can find it later
4
Under "Choose an imported project," tap Create project → name it Flowverse BJJ
5
Tap Create key — if Google shows an error, just tap it again
Paste it in
Click Copy key next to the key named for this app in AI Studio's API Keys page, then paste the whole thing here — not the project name, not your Google account.
{{ wizardDraftHint }}
Free tier basics: plenty of requests per day for personal training use, resets daily. Google may use free-tier conversations to improve their models — switch to a paid Anthropic key in Settings later if that matters to you. Exact current limits at aistudio.google.com/rate-limit once signed in.

Your belt is your one overall rank. Each technique tracks its own DRILL stage — independent of the belt you wear.
Model: gemini-3.5-flash. Free tier available at Google AI Studio (aistudio.google.com). Note: free-tier requests may be used by Google to improve their models — use a paid tier if privacy matters to you.
Anthropic API Key
Model: claude-haiku-4-5. Pay-per-use billed to your Anthropic account. No free tier — each message costs a fraction of a cent.
Runs a small AI model ({{ localModelName }}) entirely in this browser tab — no internet needed once it's downloaded, nothing you say ever leaves this device. Lower quality than Gemini/Anthropic, but works with zero signal. Needs a WebGPU-capable browser (recent Chrome/Edge on desktop or Android; not supported on iOS Safari yet). One-time download, ~{{ localModelSizeMB }}MB.
⚠ Known limitation: small on-device models sometimes over-flag grappling terms (choke, submission, attack) as violence and refuse to answer — a quirk of their generic safety training, not something this app controls. Gemini and Anthropic don't have this problem. If it happens often, Gemini's free tier is the better default.

Pulls if remote is newer, pushes otherwise. Token needs repo write scope. The target repo should be private — separate from the app's public source repo.
💾 Backup & Restore
Saves a JSON file with your progress, notes, chains, dilemmas, and settings. Keep it somewhere safe — restoring replaces what's on this device.
🔮 Export to Obsidian
Writes one Markdown note per technique you've worked on — with [[wikilinks]], your notes, journal, tagged film, and DRILL stage — plus journal / flow / chains / curriculum summaries, into a vault folder you pick. On phones (no folder access) it downloads one combined .md instead.
