Professional publishing intelligence for indie authors & publishers. The Gutenberg Signal transforms book reviews into actionable opportunities, competitive insights, and direct-to-fan strategies.
Where reader feedback becomes publishing strategy.
What the signal does
Reviews aren't just sentiment — they're a map of what readers want next. TGS reads that map for you.
Every review surfaces what readers are actually asking for — turned into concrete next moves, not a wall of star ratings.
See how your titles stack up against the field, and spot the gaps reviewers keep naming in books like yours.
Turn reader feedback into a direct line to the people who already love the work — and the ones about to.
