You skip the Wall of Flesh for three in-game days because you're not ready. Your companion respects the caution. The Corruption is spreading. The respecting continues.
You use a Gravitation Potion for the first time and spend six minutes not touching the ground. Your companion watches the biome count increase rapidly.
You dig straight down to the Underworld and survive. Your companion calls it unorthodox but acknowledges the result.
You accidentally trigger a Blood Moon on Night 1 before you have armor. Your companion watches what happens next with focused attention.
You summon the Eye of Cthulhu at 9pm in-game and realize you have no arena. Your companion has been thinking about this moment since you dug into the Spider Cave without a platform.
You craft a Terrablade and feel unstoppable. Then you walk into Duke Fishron's arena. Your companion notes this is an important learning experience.
You enter Hardmode, the Hallow spreads across your base, and your Jungle biome turns purple within 48 in-game hours. Your companion was going to warn you about the V-pattern. Timing just didn't work out.
You find the Shimmer liquid in the Aether and immediately throw your best weapon into it to see what happens. Your companion watches with genuine scientific curiosity.

Real-Time Screen Vision for Terraria
Questie's Vision Language Model reads your screen the same way a human would watching over your shoulder — no game APIs, no plugins, no special setup.
AI Watches Your Screen Like a Friend Over Your Shoulder
Questie's Vision Language Model spectates your Terraria session by analyzing your screen in real time. It reads boss progression and biome exploration, the resource screen, player positions when visible, and map state — the same way a human coach watching your stream would.
No API integration required. The AI processes what's actually on your display and responds through voice chat while you're still in the session.
What the AI sees
When feedback arrives
Commentary Arrives When You Can Actually Use It
Feedback lands during natural breaks — between engagements, after a death, or when you're repositioning. The AI doesn't talk over active high-stakes moments but pipes up when you can actually act on the advice.
After an engagement resolves, it might call out a repeated mistake with your crafting trees and class builds or remind you about a positioning principle you've been ignoring all session.
Context-Aware Commentary Matches Your Play Style
The AI adapts its tone based on how you play. Aggressive players get timing and boss progression and biome exploration reminders. Methodical players hear about positioning and macro decision-making. It responds to what's actually happening in your specific session.
This isn't cookie-cutter tips pulled from a database. The AI watched your last twenty minutes and has opinions about what specifically keeps costing you.
Not another generic chatbot
Five Things Your Terraria AI Notices
Each area targets a real Terraria-specific skill gap — not generic gaming advice.
Boss Progression Order and Arena Preparation
- Terraria's progression is boss-gated -- skipping a boss or fighting one in the wrong order means you're underprepared for the gear it drops, which feeds directly into your ability to tackle the next one. The correct pre-Hardmode order is King Slime, Eye of Cthulhu, Eater of Worlds or Brain of Cthulhu, Queen Bee, Skeletron, then Wall of Flesh. The AI watches your current gear, health, and biome status and tells you when you're ready for the next boss fight, which one to target first, and when you're not ready and need to farm another biome first.
- Arena building is Terraria's most overlooked skill. A flat 300-tile platform with Campfires, Heart Lanterns, and Sunflowers placed every 40 tiles transforms a boss fight from a survival scramble into a positioning game you can actually win. The AI watches your boss fight preparation and tells you when you're about to attempt a Skeletron fight without a platform, or a Wall of Flesh run without a hell bridge -- the two most common pre-Hardmode deaths that are entirely avoidable.
Class Build and Weapon Progression
- Terraria's four classes -- Melee, Ranged, Magic, and Summoner -- each have distinct weapon progressions, armor requirements, and accessory priorities. The gap between a focused class build and random weapon collection compounds with every boss tier. A Melee player who still uses a Copper Sword in Hardmode isn't playing Melee, they're just dying slowly. The AI watches your equipped items and tells you when your weapon, armor, and accessories are mismatched for your chosen class, and which upgrade to prioritize from your current inventory.
- The 1.4 Journey's End and 1.4.4 Labour of Love updates reshuffled class priorities at multiple tiers -- the Zenith sword as Melee endgame, the Terraprisma summon requiring Empress of Light during daytime (one of the hardest optional fights in the game), and the Celebration MK2 for Ranged. The AI knows the current meta progression path for your chosen class and tells you which boss loot or biome chest to farm next.
Hardmode Survival and Biome Management
- Defeating the Wall of Flesh triggers Hardmode -- and immediately starts a clock on your world. The Corruption or Crimson and Hallow biomes spread in a V-pattern from the center of the world, converting nearby blocks. If the Jungle gets corrupted, you lose access to essential Hardmode crafting materials that you cannot get any other way. The AI watches your world map and tells you when biome spread is approaching a critical area, when to use Purification Powder, and when a Clentaminator run (unlocked post-first Mechanical Boss) should be your immediate priority.
- Hardmode Mechanical Bosses -- The Destroyer, The Twins, and Skeletron Prime -- are the three mandatory checkpoints after Wall of Flesh. The Destroyer is widely considered the easiest first target using a Daedalus Stormbow with Holy Arrows, a strategy that carries most players through all three. Defeating any Mechanical Boss spawns Plantera's Bulbs in the Jungle. The AI knows your current Hardmode progression stage and tells you what the most time-efficient next step is for your class and current gear.
Crafting Trees and Item Discovery
- Terraria's crafting system is an invisible web. Many items require combining components at specific crafting stations -- the Tinkerer's Workshop for accessories, the Mythril Anvil for Hardmode gear, the Ancient Manipulator for endgame equipment. Most new players don't realize an item exists until they accidentally find a component for it or see it on a wiki. The AI knows the full crafting tree and tells you when an item in your inventory is a component for something significantly better that you're two materials away from crafting.
- Shimmer liquid -- added in 1.4.4 and found in the Aether mini-biome underground -- lets you transmute items into rarer versions or deconstruct crafted items back into components. It's one of the most powerful late-game systems and one of the least understood. The AI knows the Shimmer transmutation table and tells you when you have an item that Shimmer transforms into something worth the biome expedition to find it.
Expert Mode and Master Mode Adaptations
- Expert Mode in Terraria isn't just harder stats -- it changes boss behaviors. The Eye of Cthulhu gains a second phase charge pattern. The Wall of Flesh becomes faster the longer the fight lasts. The Twins split into Retinazer and Spazmatism with independent phases that punish players who kill one too quickly. Every boss fight in Expert Mode has a mechanical wrinkle that punishes the same tactics that worked in Normal Mode. The AI knows the Expert Mode behavioral changes and tells you what's different before you're dead learning it firsthand.
- Master Mode adds 1.5x Normal health and damage, plus exclusive cosmetic drops and the Master Mode Trophy for each boss. It also grants the Relic system and special Master Mode-exclusive pets. Running Master Mode without the right class build and arena infrastructure is survivable but punishing. The AI watches your difficulty setting and calibrates its advice to the specific boss behaviors and stat multipliers active in your current world.

What Your Terraria AI Focuses on at Your Level
The companion adapts to where you are — not everyone gets the same generic advice.
Building Fundamentals
boss progression and biome exploration and basic positioning are the highest-leverage areas at this level. The AI focuses on building consistent habits before layering in more complex decision-making. Most players in Pre-Hardmode Explorer are losing ground to the same correctable mistakes — the AI identifies and targets those patterns directly.
Decision-Making and Consistency
Fundamental mechanics are developing but decision-making errors are holding you back. The AI focuses on crafting trees and class builds and how to position in the situations you're consistently struggling with. Mistakes become more punishing at this level — the AI calls out the habits that compound before they compound.
Optimization and Efficiency
Mechanics are solid. Coaching shifts to finding the small edges — resource efficiency, timing refinement, reading the game state, and reducing inconsistencies that prevent further improvement. At this level the AI tracks tendencies and patterns that create predictability opponents can exploit.
Competitive Sharpness
At the highest levels the AI acts as a consistency and focus tool — keeping fundamentals sharp during long sessions and flagging mental game drift when fatigue or tilt starts showing up in your play. It also catches the subtle patterns that develop over time: predictable tendencies and decision shortcuts that work lower down but get punished here.
