Ainna AI

AI brainstorming and evidence-based idea grading for product teams

Opportunity grading on ten dimensions

Every shortlisted concept receives a letter grade with the underlying market, competitor and user research shown, plus a clear callout of the dimension doing the most damage to the score.

Brainstorming mode

Generates additional concept variations across multiple rounds and adapts to what the team rejects, so the solution space keeps expanding beyond the obvious options.

Blind expert review

Invite colleagues and trusted specialists to grade the same concepts independently, with their scores kept separate from the AI verdict rather than averaged into it.

Twelve generated document types

Turn the work into pitch decks, PRDs, FRS documents, architecture outlines, one-pagers, problem-framing decks and social carousels, all editable in PowerPoint or Word.

Strengths & Pros

+Grades ideas critically instead of complimenting them, which surfaces weak concepts before significant investment
+Every score comes with visible reasoning, sources and stated assumptions rather than an opaque number
+Document generation is tied to the actual research, so PRDs and decks reflect the work rather than being empty templates
