How Twin keeps you inside the funder's rules
Every scheme has its own structure, its own questions and its own limits. Twin holds that shape for you, so what is left to do is the substance.
The document type carries the funder's structure
A document type is the scheme's form, encoded. When you start a document with it, you get the sections the funder asks for, in the funder's order, each with the funder's own guidance. A WBSO application opens with Projectomschrijving and runs through sections such as Fasering werkzaamheden and Technische knelpunten en oplossingsrichtingen programmatuur. Expand Instructions on a section to read what that section is expected to contain.
Length limits per section
Where the scheme caps a section, the section shows its length against that cap, as a word count or a character count depending on what the funder measures. Sections the scheme does not cap show no counter.
Input quality shows what is still missing
Every section carries an Input quality score: how much of what the funder asks for is actually present in your material. Open the Table of contents in the document header to see the score for the document and for each section, with Twin's own explanation: "A higher input quality score means more of the required information is provided, resulting in less AI hallucination."
To see how a score was reached, open the three-dot menu on a section and stay on the Input criteria tab. It lists every criterion the scheme sets for that section, what Twin found for it, and the Score weight that criterion carries in the total.

You approve the plan before anything is written
The assistant drafts a project plan first and then stops. The project page shows Waiting for your approval with the note Twin won't start writing sections until you approve. Nothing is written until you press Approve, which is your chance to correct the reading of the call before it reaches every section. When the plan changes later, the assistant re-checks the sections it has already written against the new plan instead of leaving them behind. See Projects: where an application comes together.
The assistant says what it cannot do
Where your sources do not support a claim, the assistant says so instead of filling the gap. Take that as a task for you or your client, not as a failure: the fastest fix is usually to add the missing source. See Working with the assistant.
Comments are the correction loop
You stay the expert on the scheme. Where Twin gets a section wrong, leave a comment on it: the assistant reads open comments the next time it works on that section, and you can hand a comment to it directly with Apply. See Giving expert feedback on a section.
Good to know: Twin holds the structure, the limits and the funder's instructions. The judgement about whether the application is good enough to submit stays yours.
