Mycel
AI team for service firms: drafts recurring client work in your format, writes outreach, chases invoices.
Mycel is an AI team for service firms that drafts the recurring work you send clients in your format, delivers it through a client portal under your name and bills approved work. The first client deliverable is free with no card; plans start at $19 a month billed monthly, or $190 a year billed yearly.
About Mycel
You describe one piece of client work, add the client's files and, if you have one, a past example of that work, then set delivery rules. Mycel reads that example and writes down what it thinks your practice is for you to correct; each job then runs on your template and rules and checks itself first. A draft that contradicts its own numbers, leaves a required section empty or keeps a placeholder is held with the reason written out, and an edit you make becomes a rule for that client.
Clients read the work in a portal under your firm's name, on your own subdomain once you point DNS at it, where they download each released version, accept it or ask for changes, answer what the work is waiting on and see their invoices if you bill through Mycel. Mycel asks clients for missing files once, with a date, and nudges until they arrive; with Stripe connected, accepted work invoices itself with a pay link and late payers get a reminder in your voice.
Outside client work, Mycel watches for buying moments and drafts first notes to businesses that may need you, sending them once you approve the campaign, and it can write one post a day from work you did, for channels such as LinkedIn, and build your firm's site, previewing every change. You can ask it in plain language who owes you money, what is late or what you promised a client. Mycel's FAQ says prospect research and outreach have a separate plan and setup terms.
Billed monthly, Solo is $19 a month for 2 clients, Practice $69 for 5, Studio $129 for 10, Firm $219 for 20 and Agency $699 for 60; billed yearly they cost $190, $690, $1,290, $2,190 and $6,990 a year.

Mycel pros and cons
Pros
- You can try it on one real job first: the first client deliverable is free and needs no card.
- Only your client can mark work accepted; Mycel's docs say nothing inside your business can, not you, an agent or an admin.
- Per the security page, the AI runs in a sandbox with no secrets and never holds a credential, credentials are encrypted at rest with AES-256-GCM, and the audit log is append-only and hash-chained.
- Each client's work is kept apart, and Firm and Agency add isolated client logins.
Cons
- Mycel's pages disagree on sending: the homepage FAQ says automatic delivery is on by default for eligible work that passes its checks and can be turned off or set to require review per engagement, while its docs say deliverables always wait for your release.
- The security page says Mycel has no SOC 2 or formal pen test yet, and no data classification, field-level redaction or residency, so special-category data is out of scope.
- Its docs say Mycel does not fit one-off work with no precedent, work that is mostly a conversation, or work whose output you cannot check.
- The FAQ says checks are not a guarantee of correctness, and deep models for hard work come only with the Firm and Agency plans.
