Post Signatures

What signatures are for

A signature is a short block — typically your CTA, sign-off, contact line, or affiliate disclosure — that Aidelly automatically appends to the bottom of every post. Set it once at the workspace level and stop pasting "👉 link in bio" into every caption.

Useful for any account that ships the same closer on every post, or for agencies that want a per-client default closer without re-typing it.

Where it lives

Open Settings → Social accounts → Post signatures (/settings/social-accounts). Signatures are workspace-scoped.

Plan availability

Available on every paid plan. Variables resolve per workspace, so agencies can use a single template across all client workspaces.

Step 1 — Set the workspace default

1. Open the Post Signatures section.
2. The first row is Workspace default — applies to every platform unless an override exists.
3. Type the signature text. Use variables freely (see below).
4. Toggle Enabled by default to make every new post include this signature.
5. Click Save.

Step 2 — Add per-platform overrides (optional)

Below the default, each connected platform gets its own row:

1. Click Add override on a platform row.
2. Write a platform-tuned signature (e.g. longer CTA for LinkedIn, hashtag-heavy for Instagram).
3. Save.

If the override is empty, the platform falls back to the workspace default. If both are unset, no signature is appended.

Variables

Resolved at publish time per workspace context:

Variables that don't resolve render as literal text ({{cta}} stays as {{cta}} if brand memory has no CTA set).

Example signature:

— Sent from {{name}}
{{site}} | {{cta}}

Step 3 — Compose a post

1. Open the composer for any post.
2. Above the publish button, you'll see a signature preview block with the resolved text for the current platform.
3. Write your post normally — the signature stays anchored to the bottom of the preview.
4. To disable for this one post, toggle the signature switch in the preview block.

Nothing is ever silently appended — the preview block always reflects what publishes.

How signatures count toward character limits

Aidelly resolves the signature before validating platform limits:

• X (Twitter) — 280 chars (or 25,000 with X Premium long posts). Aidelly auto-trims the preview when caption + signature exceeds the limit.
• Instagram — 2,200 chars.
• LinkedIn — 3,000 chars.
• Other platforms — see platform limits.

If the signature would push the post over the limit, Aidelly warns you in the composer and won't let you publish until you shorten one or the other.

How signatures interact with other Aidelly features

• Composer, chat, API, agents, auto-post, repurpose — every publish surface runs the same signature resolver, so the signature is consistent regardless of where the post came from.
• Crosspost Routes — fanned-out destinations resolve their own signature per destination workspace + platform.
• Posting Sets — sets can include a "signature: off" override so a particular preset never appends.
• Brand Memory — {{cta}} reads from brand memory's default CTA field.

Step 4 — Edit or delete

From the Post Signatures section:

• Edit — change the text, toggle on/off, update variables.
• Delete — removes the row. The workspace default falls back to "no signature".

Troubleshooting

• My signature isn't appearing in the composer — check that "enabled by default" is on for the workspace default OR for the active platform override.
• Variable shows as literal {{name}} — the workspace doesn't have that field populated. Set the workspace name in /settings.
• Signature is duplicated — you probably typed it into the post body too. Aidelly never auto-removes typed text; check the body field.
• Different platforms show different signatures and I didn't expect that — you have per-platform overrides set. Open each row in the Post Signatures section to review.
