Meridian

Your IDE,
Now has an IDE.

Intelligent Document Editor

Request a demo

Meridian is an intelligent document editor built right into your agentic coding platform and IDE. It's a home outside of chat conversation, where you, your team and your agents can build context-aware plans, and documents that never go stale. Every team member can bring their own AI and platform to write and read Meridian docs. Get started in seconds.

We are in trials with teams that build world-class software

Core features

Documentation for engineers and product managers in the AI age

Plan, design, share and ideate in documents, not chats, using Meridian’s content-rich format. Build a repository of knowledge your colleagues actually read, while saving tokens. And never worry about docs going stale.

Markdown is dying

And the people killing it built Claude Code. Working in md has become default practice for engineers in the AI era but AI and humans prefers HTML and that's why Claude and Meridian is built on top of it.

Save Tokens

When engineers don’t have docs, you pay an agent to re-explain the system every time someone asks. And when you do have docs, they go stale and can’t be trusted. Either way, it costs you tokens.

Designed for engineers and product

code-aware docs both teams can read

Cursor CanvasBuilt for engineers in the editor. Product teams are left out.

NotionStrong for product teams, but it knows nothing about the code.

Staleness checks

flags docs whose sources changed

MeridianEvery doc remembers the code and docs it was written from, and flags itself when any of them change.

Embed docs in code

docs that open right inside your repo

MeridianReplace README.md with README.mrdoc to see your Meridian docs directly in your codebase.

ObsidianMarkdown notes can live in the repo, but nothing ties them to the code.

Live code references

doc text linked to code on main

MeridianCode references in a doc stay synced to your main branch on GitHub, and flag when the code they point to changes.

Inline editing, not regeneration

change one line without redoing the rest

Cursor CanvasA canvas is regenerated from scratch to change it.

ChatGPT SpacesArtifacts are regenerated from scratch to change them.

Claude ArtifactsArtifacts are regenerated from scratch to change them.

Multiple authors

anyone on the team can edit

Cursor CanvasOnly the person who made a canvas can edit it.

Claude ArtifactsOthers can remix a copy, but only the author can edit the original.

ObsidianOnly through community plugins.

Runs code

scripts run from the doc in your terminal

ChatGPT SpacesRuns code in a hosted sandbox, not on your machine.

Testimonials

I write a runbook, hit cmd+enter, and the command runs in the terminal beside it. It changed what 'documentation' even means for our oncall rotation.

Anderson

Full-stack engineer, Stripe

Code references alone justified the rollout to our team. A new hire clicks a symbol in an onboarding doc and they're inside the function.

Wesley

Senior Engineer, Okta

The 'docs are stale' excuse died the day we switched - every PR now updates the spec it touches, because the spec sits in the same repo.

Anne

Full-stack engineer, Stripe

The code references feature especially caught my eye. Keeping docs from going stale is such a real pain point.

Lia

Engineer, Datadog

Baking code and docs in the same context window makes working with AI so much better. Meridian gives AI the toolbox to represent plans, in a human-readable way.

Ben

CTO, Flagship

Stickies is my favourite. In the AI age, I run shell scripts and terminal workflows many times a day and now everything is easier. I love it.
