The everyday reality

Reviews rarely fail because of the book. Usually it's the organisation.

Ten requests, three channels, two deadlines in your head. After the third collaboration, you lose track.

Contacts are buried in DMs

Commitments are scattered across Instagram messages, emails and comments, and none of it is searchable.

Material sent out again and again

Review copy, cover, blurb and sales links go out to each person individually, gathered together from scratch every time.

Deadlines with no home

Who agreed when, when was the review supposed to come out, and where was that link again?

What you get

One place for everything that's part of working together.

Find the right partners

Search for bloggers and invite them with your own link.

How it works

From request to review.

Create material

Bundle book, files and sales links in one pack.

Invite bloggers

Find them via search or bring them in with an invitation link.

Send a request

Request a collaboration and track its status.

Track the deadline

Commitments with a date keep everything in view.

Receive proof

Bloggers submit the link to their review.

Material

A pack that speaks for itself.

For each book, you create a material pack: title, series, files and sales links. Anyone who commits gets access, without you having to send anything individually.

Files of up to 25 MB can be uploaded, from the sample chapter and the cover to the press kit.

  • Files up to 25 MB per upload
  • Sales links right next to the material
  • One pack per book or series
Pipeline

Every request has a status.

Open, accepted, declined: the status of a collaboration is always clear. Your roster collects the partners it has worked well with.

Bloggers see their own view with the requested titles, deadlines and what is still open.

  • Clear status values instead of message threads
  • Roster for recurring partners
  • Separate views for both sides
Commitments

Commitments with deadline and proof.

Anyone who accepts a review copy makes a commitment with a date. Both sides can see when the review is planned.

Published posts are saved as a proof link, so at the end of the campaign you have a documented list instead of a vague memory.

  • Commitments with deadlines
  • Proof links for each collaboration
  • Status open or done
Reach

Numbers before you ask.

Reach and engagement data is retrieved for profiles on Instagram and TikTok, insofar as the platforms provide it.

That way you decide whom to approach based on numbers, rather than on gut feeling and follower counts.

  • Instagram via the official Graph API
  • TikTok profile data
  • Engagement alongside pure reach

FAQ

Frequently asked questions.

A tool that authors use to organise collaborations with book bloggers: provide material, send requests, track commitments with deadlines and collect proof of published reviews, all in one place instead of in email threads.

For authors who hand out review copies and plan blog tours or social media collaborations, and for book bloggers who want to manage requests, deadlines and materials clearly.

All plans, including the Free plan. The number of bloggers and orders increases with the plan, from 5 bloggers and one order per year on the Free plan to unlimited on the Expert plan.

Yes. They register via an invitation link and get their own view with their requests, deadlines and materials. Authors and bloggers see the same status, each from their own perspective.

Files up to 25 MB per upload, for example the sample chapter as a PDF and the cover and press material as images, plus sales links. One pack applies per book or series.

Open, accepted, declined or completed: clear values that leave no room for interpretation. So you can see at a glance where each collaboration stands.

Every commitment has a deadline, such as the planned publication date of the review. Open and completed commitments are shown separately, so nothing gets lost.

Bloggers add proof links to their published posts. At the end of a campaign, you can see exactly what was actually published.

From the platforms themselves: Instagram via the official Graph API, plus TikTok profile data. No figures are estimated; engagement is shown alongside pure reach.

Your list of recurring partners. You can reach bloggers you have already worked with directly for your next release, without a new search.
