Receipts for the age of AI writing.

RedInkAI creates a clear, timestamped record of your writing process — every draft, every prompt, every edit.

So when "Did you really write this?" comes up, you don't explain. You just show.

We never read your text

Hashes only — your words stay yours.

You own your record

Export every event as PDF or JSON, anytime.

No judgement of content

We document the process. Reviewers decide.

Cryptographic chain

Tampering breaks the chain — and shows it.

What most people miss

RedInkAI doesn't just prove your work.
It improves it.

Most AI tools write for you. RedInkAI thinks with you — asking the questions that strengthen your draft instead of replacing it. Your voice gets sharper. The receipts prove it was yours all along.

Generative AI

"Write me a paragraph about X."

  • Replaces your thinking with generated output.
  • Your voice flattens to the model's voice.
  • No record of how you got there.

RedInkAI guidance

"Where is this argument weakest?"

  • Strengthens your thinking with structured prompts.
  • Your voice gets sharper — not replaced.
  • Every prompt is timestamped in your InkTrail.

Real prompts your editor will run

"Tighten this paragraph without losing the voice."

"Where is this thesis weakest?"

"What's missing from this argument?"

"Suggest 3 structural revisions for the opening."

Every prompt and your response is logged in your InkTrail — so the same record that proves authorship also shows the thinking behind it.

The moment this matters

It usually starts with a question.

"Did you use AI for this?"
"Can you prove this is your work?"
"Where did this come from?"

Suddenly, you're explaining instead of showing. Reaching for screenshots. Searching old chats. Trying to remember exactly when you wrote what.

The reframe

Show your work — don't defend it.

RedInkAI runs quietly while you write. It captures every draft, every prompt, every revision — timestamped, hash-chained, and yours. When the question comes, you don't argue. You hand over a packet that already exists.

Use it when you need it. RedInkAI is not a daily habit — it's the receipt you reach for when someone asks.

Why this exists

It started with a children's novel and a blank page.

Midway through writing a middle-grade adventure novel, the words stopped coming. So I did what any writer in 2026 does: I turned to AI for help. The prose came back polished. Competent. And it sounded nothing like me.

I didn't need a tool that writes. I needed one that thinks with me, and proves the work is still mine.

That's why RedInkAI exists. For every novelist, journalist, op-ed writer, and researcher who wants to use AI without losing their voice, and who wants the receipts to prove it. Authenticity first. Verification second. Both, always.

The hardest question we get

Can someone fake this?

Short answer: no. The whole point of RedInkAI is that post-hoc reconstruction is detectable. Here is what makes that true.

Real-time event capture

Every consultation is logged the moment it happens, with a server-side timestamp the user cannot edit. There is no "save" button on the record. The record IS the session.

Cryptographic chain

Each event is hashed into the previous event. Insert a new event in the middle, and every subsequent hash breaks. The chain detects any tampering, including by us.

Locked sessions

Once a session is locked for an attestation, the record is immutable. Subsequent edits create a new session linked to the previous one, preserving the audit trail of revisions.

Independent verification

Anyone, including your editor or integrity officer, can verify any attestation at /verify/{id} without trusting RedInkAI. The math checks out, or the chain breaks visibly.

Open testing

Our adversarial test suite (21 tests covering hash tampering, timestamp spoofing, lock bypass, and cross-user access attempts) runs against every release. Results are public.

Frequently Asked Questions

The short answers

What is RedInkAI?+

RedInkAI is a record-keeper for the way you write. It works alongside you, helping you think through your draft and quietly logging every step — the questions you asked, the AI suggestions you took or rejected, and the parts you wrote on your own. When someone asks how you made it, you have receipts.

What are guidance credits?+

Guidance credits are how the Free plan tracks usage. One credit = one guidance question ("Tighten this paragraph," "Where is this argument weakest?"). You get 25 free — enough to take a full essay or chapter from blank page to a finished, defensible draft. Student, Premium, and Professional plans get unlimited guidance, no cap.

What is the InkTrail?+

Your InkTrail is the time-stamped record of how a piece of writing came together. Every guidance question, every revision, every AI suggestion you accepted or skipped — all logged in order, linked together with a tamper-proof hash chain. Think of it as version history for your thinking.

What's an Authorship Packet?+

An Authorship Packet is the export of your InkTrail — a shareable, signed document you hand to an editor, professor, agent, or reviewer when they ask how the piece was written. It includes a verifiable link, an adoption breakdown (what AI suggested vs. what you actually used), and a clean disclosure summary. Five-minute defense, ready when you need it.

How is this different from ChatGPT or Claude?+

Those tools write for you. RedInkAI thinks with you. We don't generate paragraphs; we ask sharper questions about the paragraph you wrote — and we keep the receipt that proves the words are yours. Use AI in the room. Don't put AI on the page.

Who actually needs this?+

Anyone whose name is on the work. Students whose papers get flagged by detection tools that are wrong more than 1-in-10 times. Novelists agents now ask before requesting a full manuscript. Op-ed writers whose editors are starting to ask "is this really your voice?" Researchers facing journal AI-disclosure policies. Lawyers, consultants, policy writers — anyone for whom "I wrote this myself" is part of the deliverable.

What's TrailMap?+

TrailMap is the visual version of your InkTrail — a timeline that shows how a piece of writing evolved, with milestones for major edits and structural decisions. Useful for novelists tracking a manuscript across months, and for researchers showing the arc of a paper.
