Beta Tooling & Resilience

Shipping to real users means handling real failures.

  • PerformanceSession loading now scales to hundreds of completed days without bloat — your dashboard timeline shows your last 30 days, and asking the mentor about anything older pulls that day's full content on demand
  • FeatureFirst-run feature tour — new users are walked through every part of the dashboard on their first login, so nothing feels unfamiliar
  • FeaturePersistent feedback button — available on every page so you can flag anything the moment you notice it, not after you've forgotten it
  • FeatureReset Account — beta users can wipe their data and redo onboarding cleanly, without needing to create a new account
  • InfrastructureSession generation is significantly more reliable — a edge case that could leave the loading screen stuck permanently after a failed attempt has been resolved
  • InfrastructureAI generation now has a hard 2-minute ceiling — if your provider is slow or unresponsive, the app recovers gracefully instead of hanging indefinitely
  • InfrastructureGenerating a session now shows a cancel button after 15 seconds and a clear 'taking longer than usual' signal after 30 — you're never left guessing whether something is working
  • FixFixed: completing onboarding could in rare cases redirect you to an empty dashboard with no Learning DNA. It now catches this, rolls back, and asks you to try again

v0.8

Production Hardening

The difference between a prototype and a product is what happens when things go wrong.

  • InfrastructureYour AI Readiness Score now updates correctly every time — a sequencing issue that caused score drift when retrying a completed session has been resolved
  • InfrastructureRapid clicks and page remounts no longer trigger duplicate AI generations — eliminates the edge case where two API calls could fire simultaneously and double-charge your key
  • FeatureCost transparency in mentor chat — you now see exactly what each conversation cost on your API key, not an estimate
  • FeatureGemini users: AI costs were previously being undercounted because reasoning tokens weren't included. This is now fixed — what you see is what you actually spent
  • InfrastructureYour Learning DNA is now protected against data conflicts — if you complete sessions from multiple devices or tabs, the most recent update always wins cleanly
  • FeatureErrors across the dashboard now tell you what went wrong and what to do — invalid API key, rate limit hit, network failure — each surfaces a clear, specific message instead of a blank screen
  • FeatureOnboarding form answers now save automatically as you type — refreshing the page or losing your connection no longer means starting over
  • FixFixed: if AI generation timed out during onboarding, the app previously sent you to the dashboard anyway with no Learning DNA. It now returns you to the API key step with your answers intact

v0.7

Public Architecture

Open source requires explaining your decisions, not just your code.

  • FeatureArchitecture page — full technical breakdown of how Day01.AI works: AI routing, skill file lifecycle, scoring model, BYOK security model
  • FeatureScroll-driven technical walkthrough animation (5 scenes, Framer Motion)
  • FeatureOpen source on GitHub under MIT License
  • FeatureInvite-only beta launch with closed-access gating via environment flag
  • PerformanceLanding page rebuilt: mobile-responsive nav, reduced bundle, semantic structure

v0.6

AI Readiness Score

Learning without measurement is just reading. We added measurement.

  • FeatureAI Readiness Score — composite metric across quiz accuracy, exercise quality, streak consistency, and phase progression
  • FeatureXP system: +15 XP for perfect quiz, +15 XP for substantive exercise, +5 XP for 7-day streak
  • FeaturePhase multipliers — later phases weight contributions higher (Hands-On: 1.5×)
  • FeatureStreak tracking with decay: 3+ inactive days reduce score by 1/day
  • InfrastructureScoring pipeline runs atomically — score update and session completion in a single guarded transaction

v0.5

Onboarding & Multi-Provider

Cold-starting personalization at sign-up, not after 5 sessions.

  • FeatureFull 8-step onboarding: role, industry, goals, learning style, experience level, timeline, self-assessment, API key setup
  • FeatureMulti-provider AI: Anthropic Claude, OpenAI GPT, Google Gemini — user selects and brings their own key
  • FeatureLearning DNA generated at onboarding completion — users arrive at their first session already profiled
  • FeaturePer-provider model fallback chain — if primary model fails, silently retries on next available model
  • FeatureAPI Keys Guide: step-by-step instructions with cost transparency (~$0.02/session, no subscription)
  • InfrastructureAES-256 client-side encryption for API keys — keys never reach the server

v0.4

AI Mentor

A lesson teaches. A mentor remembers.

  • FeatureAI Mentor — persistent chat assistant with full session history context
  • FeatureMentor system prompt loads skill file + last 10 sessions on every turn
  • FeatureContext badge shows 'N sessions loaded' — transparency into what the mentor knows
  • FeatureMessage history stored per-user with 50-message cap and 4,000-char per-message limit
  • InfrastructureStreaming responses via SSE for all three providers (Anthropic, OpenAI, Gemini)
  • InfrastructureFallback to non-streaming with word-delay simulation for providers where streaming is unavailable

v0.3

Learning DNA

The core insight: AI tutoring shouldn't start from zero every session.

  • FeatureLearning DNA — a versioned markdown document capturing role, goals, curriculum, mastery signals, and gaps
  • FeatureDNA auto-updates after every completed session: topics mastered, weaknesses surfaced, next session pre-planned
  • Feature4-phase curriculum structure embedded in DNA: Foundations → Role-Specific → Hands-On → Stay Current
  • InfrastructureSkill file stored in Supabase with version column — full history preserved, conflicts resolvable
  • InfrastructureCurriculum generation uses user profile + industry context + previous session data as AI prompt inputs

v0.2

Structured Sessions

A lesson alone isn't a session. A session tests, applies, and closes.

  • FeatureQuiz module: 4-option multiple choice, instant feedback, explanation on correct answer
  • FeatureExercise module: open-ended written response with minimum length validation
  • FeatureMyth Buster: one AI misconception debunked per session, relevant to the lesson topic
  • FeatureSession state machine: lesson → quiz → exercise → complete
  • InfrastructureSession data stored in Supabase with completed flag, quiz_responses, and exercise_response columns
Feb 28, 2026
v0.1

Initial Release

Started as a tool built for one person who felt behind on AI.

  • FeatureAI-powered lesson generator: role + topic → structured 5-minute lesson
  • FeatureLesson format: concept explanation, real-world application, key takeaway
  • InfrastructureNext.js 15 App Router, Supabase Auth, Tailwind CSS v4, multi-provider AI abstraction layer
  • InfrastructureDirect browser-to-provider AI calls — no proxy, no usage data, no server-side AI handling
