Best atAutomating repetition.
Watch forIsak may build a tool when a one-off would do. Say when the job really is one-off.

Give Isak a job like this: “Isak, fact-check a 1,500-word article seeded with six errors; return the claims table.”

  • Nothing marked confirmed without a source

Works with

Work Trial

The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.

Where Isak stops

  • Works only in Claude, on your own Claude account.
  • No invented sources, quotes or data. Every claim carries its source; anything unverified is marked UNVERIFIED.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
