Do I need to be a developer to use ReadmeDB?

No. If you use ChatGPT, Claude, Gemini, or any AI assistant, ReadmeDB lets you write your preferences and context once, then paste it into any chat instantly. No technical setup required — just sign up, write a file, and copy it when you need it.

How do I keep my context across ChatGPT, Claude, and Gemini?

Write a markdown file in ReadmeDB with your preferences, ongoing projects, and anything you want every AI to know. Copy the file content and paste it at the start of any chat. When things change, update the file once — every future session gets the latest version.

What is ReadmeDB for AI agent builders?

ReadmeDB is a hosted MCP (Model Context Protocol) server that gives AI agents persistent file storage. Agents lose state between sessions — ReadmeDB fixes that. Add one JSON config line, and your agent gets 16 tools to read, write, search, and version markdown files across any session.

Which AI tools does ReadmeDB work with?

For agents via MCP: Claude Code, Cursor, Windsurf, Codex CLI, Claude Desktop, and any MCP-compatible host. For everyone else: ChatGPT, Claude, Gemini, Grok, Perplexity — any AI you can paste text into.

What is MCP (Model Context Protocol)?

MCP is an open standard by Anthropic that lets AI agents connect to external tools and data sources. ReadmeDB implements an MCP server so agents can read and write your files automatically — without you copying and pasting anything.

Is there a free plan?

Yes. The free plan includes 50 files, 5 MB storage, 3 API keys, and 60 requests/minute. No credit card required. The Pro plan is £5/month for unlimited files, 50 GB storage, and unlimited keys.

How is ReadmeDB different from each AI's built-in memory?

Each AI's built-in memory is siloed — your ChatGPT memory doesn't carry over to Claude or Gemini. ReadmeDB gives you one central file that works with every AI. You also control exactly what's in it, can see its full history, and can update or delete it at any time.

Who it's for

Two problems. One solution.

For builders

Building an AI agent?
Give it a memory.

Agents lose state between sessions. ReadmeDB gives your agent a hosted filesystem via MCP — it writes task notes, reads them back next run, and keeps a full version history. One config line.

# mcp.json
"readmedb": {
  "url": "app.readmedb.com/api/mcp",
  "auth": "Bearer rdb_…"

How it works

Three steps. Any AI, always ready.

Write your context

Store anything as a plain markdown file — agent rules, task queues, your preferences, your current project. Plain text you control.

# my-context.md
## Preferences
— concise answers only
— bullet points, not prose
## Current project
Building an AI scheduling agent
✓ Saved · versioned · searchable

Use it anywhere

Connect via MCP for automatic agent access. Or copy and paste the file into ChatGPT, Claude, or Gemini — any AI, any time.

# Two ways to use it
MCP → agent reads automatically
Copy → paste into any AI chat
ChatGPT · Claude · Gemini · Cursor
Windsurf · Codex · any MCP host

Always current

Update the file when things change. Every AI session after that gets the latest version. Full version history kept automatically.

# version history
› get_file_history("my-context.md")
  ↳ v4 · today
  ↳ v3 · 2 days ago
  ↳ v2 · last week
✓ Restore any version

What it can do

Three jobs. Sixteen tools.
Zero ceremony.

Write plain markdown files — notes, decisions, context, rules. Anything your AI needs to remember next time.
