It doesn’t write for you, and it doesn’t tell you how to write
therka is a companion for the development phase of a screenplay. It isn’t trying to compete with formatting software, or with AI writing tools.
It works best once you have a script, finished or halfway there. therka recognises screenplay-formatted text (Fountain, FDX, TXT, .therka). It doesn’t work well with treatments, free text or literary works.
Talk to your character
They answer only from what you wrote, or what you told them. They add no new facts, and assume nothing.
See what they’re not saying
Every reply comes with one sentence about what the character might be thinking underneath. It shifts as the conversation goes on.
Emotional arc, scenes, key moments
Drawn from the script itself, not from what you think is in it. It adds nothing and takes nothing away.
Your work is yours
We send your script to the AI provider (Anthropic) only so we can analyse it and your characters can speak. We don’t use it to train AI models. You can import and export at any time. Details in the privacy notice.
Languages
The menu, the analysis and the chat are available in English and Hungarian. In beta, you can also work in German, Polish, Romanian, French, Spanish, Italian, Portuguese and Dutch: the chat, the inner voice, the profile, the memory and the analysis all work in these languages too, with the menu in English.
Where it came from
You’ve probably been there: you knew what your character does, and why. Still, something was missing. How do they really talk? What would they say if you could sit across from them? Would they keep something from you?
That’s what isn’t written in the script, yet you want the audience to feel it. That’s where therka came from.
About AI
If you’ve tried, you know: a feature-length script, up to 180 pages, isn’t easy to work through with AI. therka knows your whole script, from the first scene to the last. The analysis is always made from all of it, and your characters answer from it too. If you’ve kept writing, run the analysis again and they’ll know the new version.
AI’s first idea can be more surprising than yours, but by the umpteenth it starts repeating itself. A 2024 Stanford study shed light on this too. A writer’s work, though, is exactly that umpteenth idea. That’s why therka doesn’t write for you: it uses AI where it genuinely helps, and in a way that leaves you in charge.
therka works on desktop. Open it on a computer when you’re ready.
