Features

Everything that makes a draft unmistakably yours.

Zsper is an intelligence layer: capture, scoring, assembly, and craft — with a human gate on anything that speaks in your voice. Built for how Indian founders actually write and sell.

The brain

A memory of how you think — not a chat history.

Every opinion, story, framework, and product fact is a discrete record with an explainable confidence score. Editorial records say how you write; commercial records are what your company knows.

  • Explainable confidence

    Trust is computed from recency, corroboration, endorsement, and reuse — minus conflict and cut prose. You see the component breakdown, never a bare number.

  • Review by exception

    Novel stances land as proposals; near-duplicates merge; everything else auto-confirms humbly. You only weigh in when it matters.

  • Self-optimizing

    The brain consolidates duplicate clusters into canonical records and sweeps for conflicts on its own — it stays sharp instead of bloating.

Drafting & craft

It compiles your knowledge, then writes.

Before the model runs, a deterministic engine selects your most-relevant, most-trusted knowledge and hands it a brief. The model only phrases it — grounded strictly in what you actually said.

  • Deterministic assembly

    Selection by relevance × confidence × recency, type-balanced and budgeted. Same inputs, same choice — the model never freestyles which ideas to use.

  • Voice fingerprint

    Drafts against real excerpts of your published prose with measured rhythm and vocabulary — not adjectives about your style. Your Indian English stays yours, never flattened into American blog-speak.

  • AI-tell audit

    A deterministic detector flags banned phrases, uniform openings, and summary closers, then runs one targeted rewrite to remove them.

  • Grounded, always

    Never invents a stat, name, date, or quote that isn’t in your brief. If you didn’t say it, it doesn’t ship. Your numbers stay in rupees, lakhs, and crores — exactly as you gave them.

Why WhatsApp beats an app for Tier 2 retail

A kirana owner in Nashik doubled his monthly orders the week he moved billing to UPI. No app download, no onboarding call. The difference wasn’t technology — it was meeting him where his customers already were…

…our partners repay in 11 days against the 45-day industry norm. Trust first, app later.

Built using 2 opinions · 1 customer story · 1 product fact from your brain.

Trust & control

Nothing speaks for you without your sign-off.

New stances are proposals until you confirm them. Contradictions go to a review queue with both sides shown. Losing beliefs are suppressed and traced — never silently overwritten.

  • Conflict review

    The deterministic resolution ladder proposes a winner; you settle it. Destructive edges never land as approved on a guess.

  • No auto-publish, ever

    There is no path where the system publishes on its own. Every draft waits for a human yes.

  • Full provenance

    Every article ends with a real trace of the records it was built from — receipts, not vibes.

And more

The rest of the toolkit.

Three formats

Articles, newsletters, and LinkedIn posts from the same memory — one argument, three ways to publish it. LinkedIn is where Indian founders build distribution; it's a first-class format here.

Smart content calendar

Plans what to write and when, with reasons you can read — pillar coverage, cadence, and open drafts, never a black box. You still publish.

Content pillars

Organize around strategic themes; accept AI-suggested ideas the brain already supports with a one-click status flip.

Conversational outlines

A short editorial Q&A replaces the blank prompt box — who it’s for, what you believe, which story proves it.

Import your back-catalog

Paste posts or upload files; each extracted insight is staged for your approval before it enters the brain.

Brand fingerprint

A learned profile of your positioning and tone that keeps every draft on-brand across a workspace.

Publishing flywheel

Shipping promotes what survived your edits and penalizes what you cut — the brain gets more yours over time.

Per-workspace isolation

One brain, brand, and pillars per voice. Client voices never cross-contaminate.

Bring your own key

Run on your Anthropic or OpenAI key — encrypted, metered, and never billed by us.

MCP connectors

Expose your brain read-only to Claude, ChatGPT, or any MCP client, scoped to one workspace.
