THE PROBLEM

Writing code isn't the hardest part of building software.

It's deciding what to build. How to build it. What order to build it in. And making sure nothing important falls through the cracks between standup and commit.

ML

“The bottleneck isn't typing. It never was.”

— Maria L., Engineering Lead · Stripe alumni

THE SOLUTION

Four movesfrom a sentenceto shipped code.

Synter doesn't replace your engineers. It does the thinking, planning, and scaffolding so the humans can do the interesting part.

01FOUNDATION

It starts by learning what you're building, not just what you're typing.

Synter reads your docs, code, and conversations to build a shared understanding of the project before a single story is written. Tech stack, architecture, compliance — all grounded in your reality.

02SPECIFICATION

Features become user stories, priorities, and acceptance criteria.

Every feature is broken into P1 / P2 / P3 stories with the criteria the code will be measured against. Ambiguity gets caught before it becomes a bug.

  • P1User can sign up with email & password
  • P1User can log in to an existing account
  • P2User can reset a forgotten password
  • P3User can enable two-factor auth

USER STORY

As a user, I want TOTP-based 2FA so my account stays secure if my password is compromised.

ACCEPTANCE

  • Backup codes generated on enable
  • Recovery email required
  • Trusted device list
03ROADMAP

A plan that knows what blocks what.

Stories arrange themselves into phases. Dependencies are automatic. Risks and edge cases surface before they become Friday-night regressions.

04AUTONOMOUS BUILD

The agent opens a pull request. You review it.

Code is written against the spec, one task at a time, with tests and commits that follow your conventions. The first thing you read is a PR — not a prompt.

HOW IT WORKS

Minutes from idea to the first commit.

00:00STEP 01

You describe it.

A plain sentence. A napkin sketch. A Notion brain-dump. Synter accepts the mess.

“A tool that lets me track client projects, time, and invoicing.”

01:24STEP 02

Synter writes the spec.

Features, stories, priorities, and the questions you haven't thought to ask.

  • · 8 features
  • · 47 stories
  • · 12 acceptance criteria
03:48STEP 03

You approve the plan.

Reorder, cut, or rewrite. A single click sends the agent to work.

It ships — in PRs.

Each commit arrives as a pull request with tests, context, and a rationale.

EVOLUTION

Three generations of talkingto machines.

1960sPAST

Speak the machine's language.

MOV AX, 01h MOV DX, OFFSET msg INT 21h

Assembly and punch cards. Every instruction explicit, every byte accounted for.

2010sPRESENT

Meet it halfway.

function send(msg) { console.log(msg) }

High-level languages, frameworks, and copilots. Still English-shaped code — not code-shaped English.

NowFUTURE

Speak your own.

Build an auth system with OAuth, email login, and two-factor auth.

living

Natural language coding. The machine learns your stack, reads your intent, and writes the code.

OUR THESIS

We've spent sixty years teaching humans to think like computers.

Synter teaches computers to think like you.

DIFFERENTIATORS

Tools either plan or build. Synter does both.

PLANNERS— end of thread

Think. Then nothing.

LinearNotionFigma AIMiro
synterONE THREAD
FOUNDATION · SPEC · PLAN · BUILD · SHIP
BUILDERS— start of thread

Build. Without context.

CursorBoltLovablev0
· 01

One thread, not ten tools.

Foundation, spec, plan, and build live in one place — which means the code always reflects the spec, and the spec always reflects the idea. Nothing goes stale between tools.

· 02

It thinks before it types.

Synter doesn't generate code the moment you ask. It asks back: clarifies the ambiguous, surfaces the unknown, and grounds every decision in your codebase before the agent picks up a keyboard.

· 03

Your conventions, not ours.

Synter learns your naming, your folder structure, your test patterns. It writes code that matches what's already there — so review feels like editing a teammate, not onboarding an intern.

BUILT FOR

Built for the people who have to ship.

i.DEVELOPERS

Skip the ceremony. Keep the craft.

Spend your day in pull requests, not in planning rituals. Synter writes the boring scaffolding so you can focus on the parts that need your judgment.

› integrates with GitHub, VS Code

ii.PRODUCT MANAGERS

Specs that survive the sprint.

Write the intent. Synter handles the breakdown, the acceptance criteria, the edge cases your engineers will ask about on Wednesday.

› syncs to Linear, Jira, Notion

iii.FOUNDERS

An idea on Monday. A demo on Friday.

Go from whiteboard to working product without waiting on hires. When your first engineer joins, they inherit a real codebase — not a pile of prompts.

› loved by YC & solo founders

iv.AGENCIES & TEAMS

Three clients. One weekend. No drama.

Scope, price, and deliver without bottlenecking on engineering capacity. Synter scales with your book of work — shared specs, shared conventions, no context loss.

› SSO, audit logs, workspaces

FITS YOUR STACK

It arrives already plugged in.

01

GitHub

Two-way sync with repos, branches, and PRs — the source of truth stays yours.

02

AI models

Claude, GPT, and Gemini — bring your own keys, keep your own data.

03

Real-time sync

Spec and code stay in step — edits in one place reflect in the other within seconds.

04

Notifications

Slack, email, and webhooks — the agent tells you when a PR is ready, not all day.

Stop typing.

Start shipping.

Free while Synter is in beta. No credit card, no wait-list — just a sentence and under ten minutes.
