The AI that actuallyknows you

Most AI forgets you after every chat. meld is different — you and AI share a knowledge base. Both read, write, and build on the same files. The more you use it, the smarter it gets.

How it works

Ask anything. Agent handles the rest.

meld indexes your vault, then answers from your personal context — past decisions, projects, notes. Not generic AI. It creates and updates notes autonomously.

I'm considering pivoting to B2B. What do my notes say?

Based on [[March Retro]], [[Pricing Research]], and [[Customer Interviews Q4]], there’s a strong signal:
Your March retrospective noted 68% of inbound interest was from teams, not individuals. Pricing research shows B2B willingness-to-pay is 3–5x higher…

01

You ask

Natural language, just talk. No syntax, no commands.

02

It knows

Answers from YOUR context — past decisions, projects, notes. Not generic AI.

03

It acts

Creates, connects, and grows the shared knowledge base. Every conversation compounds.

The meld Effect

AI that gets better because it’s yours

01Week 1

You talk, it captures

Share your projects, ideas, decisions. meld captures everything as structured notes. Ask what it doesn't know — it researches, saves, and never forgets.

02Month 1

It knows your context

References past decisions without being asked. Connects ideas you hadn't linked yourself. Starts to feel like it actually understands your work.

03Month 3+

It becomes YOUR AI

Understands your thinking style, priorities, patterns. No other AI has this depth — because no other AI has your vault. A fundamentally different experience.

Why meld

Three pillars, not a feature list.

Personalization

The more you use it, the more it knows

You and AI share one knowledge base — both read, write, and build on the same files. Every conversation enriches it with your projects, decisions, thinking style. Not session memory that vanishes — a structured knowledge base that compounds over months and years.

Shared knowledge base · Compounds over time

Ownership

Your files. Your AI. Forever.

Everything lives on your device as plain Markdown. Open source, AGPL-3.0. If meld disappears tomorrow, your knowledge stays. Zero lock-in, zero compromise.

Agency

Not a chatbot. An agent.

meld doesn't wait for commands. It plans, researches, creates, and connects. You set the direction — AI does the work. From a quick question to a 50-note research mission.
