Ghost Writing in Phasmophobia Explained
The notebook is one of the most useful tools you have for identifying a ghost, and ghost writing is the passive mechanic where the ghost occasionally writes entries in it without you triggering anything. It happens on its own timer, and the type of writing can narrow down your ghost significantly. Most players barely look at their journal during a contract because they're too focused on doing evidence tasks, but if you actually read what the ghost writes, you can save yourself from having to do the Ouija board at all. Every ghost in the game has a chance to produce a writing event, but the probability varies, and certain ghosts will never write at all under normal conditions. The base chance on Normal difficulty is roughly 30% per interval, then scales down about 12% per difficulty step. So on Nightmare it drops closer to 6%. This means ghost writing is far less reliable on higher difficulties, and if you're playing with two people who keep killing each other with flashlights, you might not see a single write across an entire hour-long session. There are several categories of writing events. Random writing just appears out of nowhere, usually a sentence like "Don't touch me" or "Go away". Hunt writing triggers right before or during a hunt cycle and often contains more aggressive content. The Ouija board write is directly linked to using the board and is one of the most common forms. There's also the ghost table writing, which pops up when the ghost interacts with the table, and a few others that are tied to specific triggers like dropping below certain sanity thresholds.
Not all ghosts are equal here. The Oni, Demon, and Mare have elevated write rates and tend to produce notes more frequently than average. The Revenant and Shami are on the lower end and may go multiple sessions without leaving anything behind. I ran into a specific issue on my end a while back on the Canyon view cabin on Normal with a Shami — the ghost wrote exactly once in forty-five minutes, and I was ready to rule it out entirely. The workaround was just to leave the room and let the ghost roam freely; once it left the building, it started writing every few minutes. The Shami's movement speed drops significantly indoors, and the writing timer seems to be loosely connected to how much the ghost moves around. That's not official documentation, just what I observed across several sessions.
How to Read Ghost Writing Events
The text itself often contains keywords or phrases that point to a specific ghost. The game generates these from a pool, and some words appear far more often depending on the ghost type. For example, references to fire or burning almost always indicate the Demon, while mentions of children or family tend toward the Yurei or Moroi. If the note includes something about "speed" or "slow", that's more likely the Deogen or Revenant respectively. The trick is learning to scan for the telling word rather than reading the whole sentence like a novel. One thing most people get wrong is assuming ghost writing can confirm your ghost outright. It can't. Writing events are supportive evidence at best, never definitive. The worst scenario is seeing a note that says something vague like "I feel cold" and then spending twenty minutes convincing your team you've found the Banshee when the ghost table shows otherwise. I learned this the hard way during a Pinecrest house run where we locked onto Hantu purely because of a couple of writing clues about freezing temperatures, only to find out halfway through the contract it was a Jinn the whole time. The writing had said nothing about the bathroom specifically, and we just latched onto whatever seemed relevant.

What Makes Ghost Writing Useful
The real value of ghost writing isn't in replacing evidence gathering. It's in confirming suspicions before you run out of sanity. If the ghost writes "Stay away from the mirror" and you already have a hunch about the Myling based on your EMF readings, you now have enough confidence to start pulling triggers without burning through half your sanity reserves first. That's the shortcut. You can also use ghost writing as a sanity-saver on Nightmare difficulty where you need to be efficient. Running around checking evidence rooms blindly when you already know the ghost type wastes time and sanity. I keep a mental shorthand for the most common writing phrases and what they map to. "Can you hear me?" is typically the Spirit. "It's dark" points to the Wraith or Banshee more often than not. These aren't hard rules, but they cut down the confusion when you're trying to decide whether to bring a spirit box into a room or just check the temperature sensor instead. The writing system does have real limitations. As difficulty increases, the frequency drops steeply, and on Insanity it can be genuinely difficult to get any write event at all during a full session. There are also ghost interactions that can suppress writing — if a ghost is locked in a hunt loop for most of the game, you simply won't get as many random writing opportunities. In those cases the standard evidence approach is the only reliable path forward, and hoping for a write is just poor planning.
If you're looking to study ghost writing patterns for a project, there are public resources and spreadsheets tracking the exact wording pools for each ghost. The community has done more research than the game itself bothers to publish. The writing mechanic is well understood at this point, even if the developers never really explained the underlying system.
