The place where you understand what you wrote
therka is a companion for the development phase of a screenplay. It isn’t trying to compete with the formatters, and it isn’t trying to write for you.
It works best once you have a script, finished or in progress. You can start a new one here too, but the chat and the analysis only know what’s on the page.
Talk to your character
They answer only from what’s actually on the page — nothing invented, nothing assumed.
See what they’re not saying
Every reply comes with one sentence of what the character is thinking underneath — and it shifts as the conversation goes on.
The shape of your story
Emotional arc, scene appearances, and key moments — surfaced from the script itself, not from what you think is in it.
Your work stays yours
You can import and export at any time. Your script is sent to the AI to answer your request and for nothing else — it is not used to train AI models. See the privacy notice.
Where it stands
therka is under development, and it’s growing slowly, from the ground up. Not a finished product we’re trying to sell — a direction we think is missing.
Where it came from
I once had a character I had very little source material on. I knew what he did. I didn’t know how he spoke, what he denied, what would offend him. The structural tools you can learn were no help here — those handle the shape of the story, not what a particular person would say in a particular moment.
So I started talking to him. In my head, the way every writer does. therka grew out of that conversation.
I didn’t want it to write for me. AI can be more surprising than you with the first idea, but by the hundredth it’s repeating itself. A 2024 Stanford study showed this too. A writer’s work, though, is the hundredth idea. That’s why therka doesn’t generate text: you talk to your characters, and they answer from what’s actually in the script.
