Assemblr
built the world's first behavioural intelligence platform

What is Assemblr?
Assemblr is a workflow discovery and autonomous agents platform designed specifically for engineering teams. It reads every PR, commit, review, and message across GitHub, Slack, and Linear — along with the actual codebase — to identify routines your team keeps doing on autopilot. It then turns each routine into a ready-to-run agent with citations to the exact file and line number. Unlike traditional context brains that hoard data and resell search, Assemblr watches how teams work, grounds every claim in the code, and ships agents that close the loop.
The platform operates through four key stages: Mine (patterns mined from actual team activity with no labeling or templates), Name (patterns get plain-English names like silent merges, workflow gaps, fading routines), Mirror (a weekly briefing in investigative journalism style with specific events, dates, and patterns), and Activate (once a routine fires consistently, activate it as an agent with one click, inheriting tone, timing, and identity). The Mirror surfaces gaps in your engineering process, and Agents fix those gaps.
Assemblr is built for engineering teams who live across tools like GitHub, Linear, and Slack. It provides a vocabulary for what teams actually do through ThePatterns — a growing dictionary of work patterns like Cold review, Decay drift, Half-Friday ship, Workflow gap, Load-bearing actor, Orphan ticket, Phantom standup, Postmortem skip, Routine fading, Silent merge, Solo handoff, and Stale-design code. The engineering trio (GitHub, Slack, Linear) provides read-only data access by default, never writing to sources unless an agent explicitly does so on your behalf.
Key integrations include Vercel, Supabase, Anthropic, Cursor, Linear, and Bun. The platform positions itself as a new category called behavioral intelligence — showing what teams actually do, not what they declared. It's suitable for engineering, ops, revenue, and support teams who need to identify and automate recurring workflow patterns.
Assemblr pricing
Pricing model: Freemium
No public pricing information is available on the website. The platform appears to be in early launch stage with a waitlist model. Users can get the Mirror and see a public Mirror, but specific pricing tiers, free tier details, or paid plan costs are not disclosed on the website.

Frequently asked questions about Assemblr
What is Assemblr?
Assemblr is a workflow discovery and autonomous agents platform for engineering teams. It reads every PR, commit, review, and message across GitHub, Slack, and Linear along with your actual codebase, names the routines your team keeps doing on autopilot, and turns each one into a ready-to-run agent with citations to the exact file and line.
How is Assemblr different from a context brain?
Assemblr is not a context brain. Unlike context brains that hoard your data and resell search, Assemblr watches how your team works, grounds every claim in the code, and ships agents that close the loop. It doesn't store data for search purposes.
What tools does Assemblr integrate with?
Assemblr integrates with the engineering trio: GitHub (pull_request, push, review), Slack (message, reaction, thread), and Linear (issue, transition, cycle). It also has integrations with Vercel, Supabase, Anthropic, Cursor, Linear, and Bun. Existing Notion, Google, and Asana connections continue to ingest, but new connections to those toolkits are paused while focusing on the engineering trio.
How does the Mirror work?
The Mirror is a weekly briefing in the language of investigative journalism. It provides specific events, specific dates, and specific patterns mined from your team's actual activity. It surfaces workflow gaps and routines your team does on autopilot, giving you a vocabulary for what your team actually does.
How do I activate an agent?
Once a routine has fired consistently, you activate it as an agent with one click. The agent inherits the routine's tone, timing, and identity hints from the Mirror. Agents are never speculative and fix the gaps the Mirror surfaces.
Does Assemblr write to my tools?
No, Assemblr is read-only by default. It never writes to your sources unless an agent explicitly does so on your behalf. The data from GitHub, Slack, and Linear is read-only access.
What patterns does Assemblr identify?
Assemblr identifies patterns like Cold review (PR opened and merged with reviewer = author or no approval), Decay drift (routine firing less frequently), Half-Friday ship (deploy after 3pm Friday with no rollback plan), Workflow gap (cross-tool routine fires N-1 of N expected steps), Load-bearing actor (one engineer holds 75%+ of behavior class), Orphan ticket (Linear issue closed without code merge in 7 days), Phantom standup (standup pattern ran 4+ weeks then stopped), Postmortem skip (incident channel created, no postmortem in 7 days), Routine fading (team habit moved from thriving to dormant), Silent merge (PR merged with no Slack or release-notes followup), Solo handoff (load-bearing actor performs 80% of behavior class), and Stale-design code (code shipped while design doc untouched 30+ days).
Who is Assemblr for?
Assemblr is built for engineering teams who live across tools like GitHub, Linear, Slack, and other integrations. It's suitable for engineering, ops, revenue, and support teams who need workflow discovery and want to turn recurring routines into autonomous agents. It's for teams who have thought this should be an internal tool but it's not worth the engineering time.
What is behavioral intelligence?
Behavioral intelligence is a new category that shows what teams actually do, not what they declared. It's the same instinct as Process Mining (observe what's real, not what's declared) but applied to a new substrate: humans plus SaaS, not bots plus ERP. Assemblr uses behavioral intelligence to observe team routines and turn them into agents.
How do I get started with Assemblr?
You can start your team's Mirror by joining the waitlist on assemblr.net. You can also get the Mirror and see a public Mirror to understand how the platform works. The platform is currently in early launch and building a new way to create internal production-grade tools generated from natural language.
